depth you plow and the time you 
plow have a great deal to do with the size 
of your yield. 

any other kind of farm work. It was always 
hard to do it with horses or mules. It is 
harder than ever now that you must plow 
deeper and at exactly the right time: 

plow deep and to plow quick; power that 
is not stopped by hard ground, hot weather 
or flies; power that will run day and night, 
if necessary; and power in a concentrated 
form, so that you can do as much work as 
two or more men with horses. And after 
you plow you can also disc, harrow, pulver- 
ize and do all of the work of preparing your 
seed bed with a tractor better and cheaper 
than you can with horses. 




THERE IS NO POWER required in 
raising a grain crop that a tractor 
cannot supply. After preparing the 
seed bed, a tractor will pull a drill to put 
the crop in, pull a binder or header to har- 
vest it, drive a separator to thresh it, pull 
the wagons to haul it, and drive the 
elevator to unload it. 

PROBABLY there is no kind of work for 
which a tractor has been found more satis- 
factory, outside of plowing, than for har- 
vesting. The grain must be cut quick when 
it is just ripe, and it is then about the hot- 
test time of the year. It is a wonderful 
satisfaction to cut your grain with a tractor, 
for it doesn't have to stop to rest, eat or 
even sleep, as do horses or mules. With a 
tractor you can save your grain after you 
raise it. 

can also get a thresher and thresh your own 
grain just when you are ready, and then 
thresh as much for your neighbors as you 
want to. There's a size Avery Champion

IT WAS NOT THOUGHT at first that 
motor power could do so much in handling 
a row crop, but it has been found of equally 
as much value as in handling a grain crop. 
It is this fact which is now causing many 
farmers, who at first hesitated about using 
motor power, to become strong advocates 
of motor farming and to buy tractors and 
motor cultivators in large numbers.

A MOST ANY CROP can be handled 
better and cheaper with motor power. 

QUITE A NUMBER of tractor owners use 
their tractors to mow their hay. Many of 
them use their tractors to pull their hay 
loaders and do their hauling. Of course, if 
the hay is to be baled the tractor will also 
furnish the belt power. 

potatoes on a large scale are rapidly adopt- 
ing tractor power to do their work. Those 
who already have them say that the tractor 
makes it possible to cultivate an orchard 
much better than it can possibly be done 
with horses. Pulling a potato digger is 
also a hard job for horses, but an easy one 
for a tractor. Then, of course, you can haul 
your crop anywhere you wish with a tractor. 

THE AVERY COMPANY also builds a 
special nursery tractor, as shown here, 
about which full information will be sent to 
anyone interested. 

AN AVERY TRACTOR turns short and 
the question of using it is largely only a 
question of getting the tools you wish to 
use properly attached.

to list all the kinds of work that are being 
done with tractors. They can be used for 
supplying almost every kind of pulling 
power required. 

YOU CAN USE A TRACTOR for pulling 
a manure spreader, pulling stumps, moving 
houses, stretching fence, pulling a tile ma- 
chine, and almost anything else you have 
to do. 

MOST MEN who buy tractors find after 
they get them that they use them for many 
more kinds of work than they had planned 
on when they bought them, and they also 
learn that the extra power they have is 
of great advantage to them in doing their 


TRACTOR gives you both belt and 
traction power all in the one ma- 

over a portable engine is that it is equally 
as good a machine for doing your belt work 
and has the added advantage of being able 
to move itself anywhere you want it and 
pull a load besides. 

OWNERS OF TRACTORS use them for 
such work as feed grinding, baling, shelling, 
pumping, sawing, etc., and many men are 
buying their own silage cutters and 
threshers and doing their silage cutting and 
threshing with their own outfits, in order 
to get the work done when they want it.

WHEN THE PRICE is right and you are 
ready, you can haul your crops to market 
quick with a tractor. If you need any lum- 
ber, fuel, tile, sand, cement, etc., haul them 
back with your tractor. It has the power 
to pull heavy loads over most any kind of 

tractor can hardly realize the many places 
where a tractor owner finds that it fur- 
nishes just the power he wants for hauling. 


TRACTORS are far better than horses 
or mules for doing road work. The 
steady pull required in grading, level- 
ing and hauling road materials is too much 
for animal power, and when you hitch 
enough horses or mules to a road grader or 
a big leveler you have an awkward outfit to 
drive or turn around. It also requires too 
many men to handle such an outfit. But a 
tractor gives you a lot of power concen- 
trated in a small form that one man can 
readily handle. 

A TRACTOR will do the grading, leveling, 
hauling, rock crushing, etc., and besides 
these kinds of work you can also get a road 
roller attachment and roll your roads as

for plowing. Now they are used for all kinds of 
work. A tractor is a general all-year-around machine. 
In the spring you can plow, disc corn stalks, disc and 
harrow, drill, and pack your ground. In the summer you 
can harvest, thresh, make hay and do road work. In the 
fall you can cut silage, plow and shred corn. In the 
winter you can shell, saw, grind feed, do hauling and other 
work. The Avery Motor Cultivator also makes it possible 
now to plant and cultivate with motor power and replace 
animal power for such work. 

prices of crops, to produce all your land can possibly raise 
and do it with the least expense. It is not so much a 
question of whether or not a man can afford a tractor or 
motor cultivator as it is a question of how he can afford 
not to have one. As one man has said, "You have to be 
rich to farm entirely with horses now." 

IT IS USUALLY THE MAN who first appreciates the 
advantage of adopting better methods who profits most. 
Right now is the best time you will ever have for buying 
a tractor and motor cultivator. The reasons are because, 
in the first place, motor farming is a proven success. 
There isn't any question about motor farming being a 
success and there isn't any question about being able to 
get a successful tractor or motor cultivator. You don't 
need to experiment now the experimenting has all been 
done. In the second place, the prices of farm products 
are still based on the higher cost of horse farming. What 
you save in production with a tractor and motor cultivator 
you have as extra profit over and above your usual 



generally recognized as the most important thing necessary 
in preparing the seed bed. There are only a few days when 
the ground is in the best condition to plow, disc, harrow and plant. 
Right then is when you must do the work quick in order to raise 
the largest crops. 

IT IS ALSO JUST AS NECESSARY to do the work in the right 
way as at the right time. Reports from agricultural college ex- 
periment stations say the average depth of plowing should be 
doubled. More discing and harrowing is constantly recommended 
in order to better pulverize the ground and thus make more plant 
food available and save the moisture. 

harrow oftener would require more horses or more time. To 
double the depth of plowing would require 70 per cent more horses 
or 70 per cent more time. You can't afford to take the time or to 
keep the extra horses. To keep 70 per cent more horses would 
increase your expense to the same amount, and to take 70 per cent 
more time would mean smaller crops. 

own experience, that doing farm work at the right time and in the 
right way meant bigger crops, but when it came to the question of 
the power to do it there's where the rub came in. Horses can- 
not supply sufficient power to do farm work as it should be done 
they cannot supply power in a concentrated form so that one man 
can handle enough with his own hands they can only work a few 
hours until they must stop to eat, rest and sleep^-they are soft in 
the spring, right when you need to push your work they get over- 
heated if you push them in hot weather flies and other insects 
constantly bother them and reduce the work they do. 

THESE ARE SOME OF THE REASONS why tractors are be- 
ing bought by the thousands every year because tractors are the 
only real answer to the problem of having the power you need to 
do all your work in the right way and at the right time and thus 
raise bigger crops. 

in all parts of the country tell about the bigger crops they are now 
able to raise with tractor power. An Avery Tractor will give you 
the power you must have to practice the best farming methods. 
It will give you a lot more power power in a concentrated form 
that one man can handle power that hot weather can't stop and 
power that will work as long hours as you want to run it. An 
Avery Tractor gives you the power to raise bigger crops by doing 
all your work in the right way and at just the right time.

FARM HORSES ONLY WORK, on the average, about 100 full 
days' time per year, but they eat all the time whether they are 
idle or working. When you farm with horses or mules, they 
eat about one-fourth of all you raise. It takes the crops from five 
acres to feed each horse. 

YOU HAVE TO FEED THEM the other 265 days all for nothing, 
just to get 100 days' work out of them. It's entirely different 
with a tractor. When it isn't working it costs you nothing for fuel 
and when it is working it costs you less to do the work than to do 
it with animal power. 

DON'T FEED YOUR CROPS into idle extra horses any longer. 
Sell them then you can haul your grain to market and sell it or 
feed it into profit-making hogs or cattle. 

IT ALSO TAKES TOO MANY MEN to farm with horses or 
mules. One man cannot handle enough power with his own hands. 
This means extra hired help, with wages constantly increasing and 
men hard to get at all when you need them. 

WHEN YOU CONSIDER upkeep expense you will find that the 
cost of repairs for an Avery Tractor will average less than the 
cost of shoeing, veterinary and other expense, to keep the horses 
in shape. The investment in an Avery Tractor and Plow will 
average less than the cost of horses necessary to do the same 
amount of work The depreciation on an Avery Tractor from 
year to year will be less, if properly cared for, than with horses 
or mules. The life of an Avery Tractor will average, at least, 
as long as the working life of an average horse, and a tractor 
never dies. It can always be fixed, but you can't fix a dead horse 
with a monkey wrench like you can a Tractor. A tractor can't 
get overheated and die, it can't be poisoned by eating the wrong 
kind of food, and it isn't subject to all of the common diseases 
that attack and kill valuable horses without your being able to 
prevent them. If an Avery Tractor is given reasonable care, it 
will run steady right along, but you can never be sure what is 
going to happen with animal power. 

OTHER MEN HAVE PROVEN that farming with an Avery 
Tractor is cheaper than with horses. Why shouldn't it pay you 
also as well as it does them?

IT TAKES TOO MUCH TIME and hard work to care for horses 
and mules. In the morning you have to feed, water, curry, 
harness up and hitch up. At noon it's unhitch, feed, water and 
hitch up. At night it's unhitch, feed, water, unharness and bed. 
And horses have to be taken care of whether they are idle or 
working. They average only about 100 days' work a year and 
take vacations of 265 days' time but there is no vacation for the 
man who has to take care of them. He must at least feed and 
water them every day of the year whether they are idle or work- 
ing. Government investigations show that it requires 170 hours 
of a man's time each year to take care of one horse, or 17 full 
ten-hour days' time. Just to take care of four horses requires 
time equal to two and one-half months of ten-hour days a year. 

ENJOY LIFE MORE by farming with a tractor. Don't spend 
your time in the winter taking care of a lot of surplus idle horses. 
Sell them and get a tractor that doesn't take any care after you 
run it in the shed until you want to use it again. 

SAVE ALL THE TIME it takes you to care for your extra horses 
every day and spend it instead in enjoying life more and in 
studying out how to farm better. 

YOUR TRACTOR will also save you a lot of hard work and time 
every day you use it. In the morning it will only take about as 
much time as to care for one horse and at noon and night all you 
will have to do will be to turn the switch and you are through. 
All the extra time it takes to feed, water, harness, curry and bed 
horses you can spend in more profitable work or in getting more 
enjoyment out of life.

Some General Facts You Should Know About 

Avery Tractors 

WHEX YOU BUY A HORSE you ask how old he is and then you look 
at his teeth to see whether the facts bear out the answer that 
you get You inquire about his weight and then drive him across 
a scale to make sure. You ask about how he travels and then hitch him 
up and drive him around to make certain that he has the kind of action that 
is claimed for him. You know what a good horse is and you investigate 
the facts behind the claims that are made. 

BUYING A TRACTOR is just like buying a horse. Of course, men have 
not had so much experience in buying tractors, but by careful investigation 
and comparison you can find out what points are necessary to make a good 
tractor, and then by carefully investigating the claims for each machine you 
can determine the tractor which has the features you want. 

The Only Real Standardized 
Tractor Design 

YOU SHOULD STUDY the design and construction of a tractor from two 
points of view first, the design and construction of the individual units, 
and, second, the results of the combination of these into the complete 



Fuel System 

Ignition System 

Oiling System 
Cooling System 




YOU SHOULD INVESTIGATE the design and construction of each of these 
nine units and then should consider how well they are combined into the 
complete tractor to produce these nine results 


Light Weight 



Ease of Handling 

IT IS NO EASY THING to build a tractor where every part motor, fuel 
system, ignition system, oiling system, cooling system, clutch, transmission, 
frame and wheels are each so designed as individual units, and so com- 
bined into the complete machine as to produce a tractor that possesses 
durability, reliability, simplicity, light weight, power, speed, economy, 
accessibility and ease of handling. A chain with a broken link is useless. 
A boat with a hole in it will sink, even though the rest of the boat may be 
all right. So it is with a tractor if any part fails, the whole tractor fails. 

ON THE FOLLOWING PAGES you will find full detailed illustrations and 
discussion of the design of the nine units in an Avery Tractor and the 
results of the combination of these into the complete machine. 


facts about Avery Tractors, this one thing stands out strongly as proof of 
the success of the Avery design that Avery Tractors are the only make 
built in five sizes all alike. When a company starts building one si/.e 
tractor and then, because of its success, builds another size, then another, 
then another, and then another, until it has five sizes all of the same design, 
it is proof in itself that that design must be successful, otherwise it would 
be changed or the company would not be successful. The fact that the 
Avery Company is the only company building five sizes of tractors all of 
the same design is strong proof in itself of the superiority of Avery 

MOST OTHER COMPANIES building new sizes of tractors are building 
them of a different design than their former tractors, which is an admission 
of the fuilure of their former design, and the best that can be said of any 
new design is that it is an experiment. 

Put to the Hardest Tests 
of Any 

A TRACTOR may appear to have n pood design and construction and yet 
not show up as one would think when it comes to the actual test. 

THERE ARE THREE KINDS OF TESTS which you should investigate 
first, those made by the company itself; second, those made in public com- 
petition; and, third, those made by the users of the tractor. 

WE DO NOT BELIEVE than any company has more efficient testing appar- 
atus than the Avery Company, or that any company subjects its machines 
to a more thorough test before shipping them out to the customer. We 
are always glad to have anyone visit our factory and see how we test our 

YOU WILL ALWAYS FIND AVERY TRACTORS entered in every important 
contest and demonstration. We are always glad to show them in com- 
petition with other makes. They were the only make entered in every 
Winnipeg Motor and Plow Contest and have been entered in every important 
tractor demonstration held since the Winnipeg Contests. 

AVERY TRACTORS have also met the test of actual field use in the hands 
of owners and have proven themselves to be what we claim for them. They 
were introduced and sold for three years on a sold-on-approval policy, to be 
paid for only after they had made good in the field and been accepted by 
the purchaser. Prominent men are buying them, others in the same 
family, neighbors of the first buyers and repeat orders are also being placed 
by many men. Such men wouldn't be buying them if they were not a 

THEY ARE THE ONLY MAKE which has been proven out by all of these 
tests. They have met every kind of a test that is known and have proved 
that they will do all we claim for them and even more. 

Why You Can Buy an Avery 
Tractor at a Low Price 

AVERY TRACTORS are sold at low prices. We are able to make these 
low prices for the following reasons: First, Avery Tractors have the 
simplest construction of any. Second, they are built in large quantities 
in our own large factory, with modern equipment. Large quantity produc- 
tion in our own factory makes possible a low manufacturing cost. Third, 
owing to the decree to which Avery Tractors have been perfected, there is 
comparatively little service work required in connection with them. Fourth, 
the Avery Company has also perfected its selling methods to the place 
where we are able to market our machinery at the least expense consider- 
ing the giving of real service to our customers after they get the machinery. 
Fifth, our cash prices save you the amount necessary to add to cover the 
average collection expenses and losses on time deals. 

basis of quality plus service for the price. 

The Company Behind an 
Avery Tractor 

WHO AND WHAT IS BACK OF IT is as important a question to consider 
about a tractor as it is to consider the pedigree of an animal. Men are 
coming more and more to realize the importance of the company behind the 
tractor they buy. 

THERE ARE FIVE THINGS of which you should satisfy yourself about any 
company whose tractor is offered you first, the experience of the company; 
second, the spirit; third, the factory; fourth, the methods; and, fifth, the 

THE EXPERIENCE of the Avery Company in building tractor farming 
machinery has extended over many years in fact, the Avery Company was 
the first company in this country now manufacturing tractors and plows to 
design and build a power plowing outfit. We are, however, never satisfied. 
Our designing department is constantly at work endeavoring to make Avery 
Tractors even more successful than they are. It is this progressive spirit 
and policy which has made the Avery line so successful. The Avery Com- 
pany owns its own large and up-to-date factory where Avery* Tractors are 
built under careful supervision. The Avery policy in dealing with its cus- 
tomers is "A Good Machine and a Square Deal." We are proud to refer you 
to those who are already our customers as to our methods. And we do 
not stop with simply building and selling you a machine we have estab- 
lished our own branch houses at points most convenient for our customers, 
where we carry complete repair stocks and have our own service men ready 
to take prompt care of you in case you need any help or repairs. Avery 
Tractors are backed by prompt and permanent service. 

WE GUARANTEE and stand behind Avery Tractors and are in position to 
buck up the guarantees we give.

The Avery Motor 

The Best Combination Traction and Belt Power Plant on Wheels 

(The First Unit in a Tractor) 

BECAUSE OF THE FACT that stationary gas engines and automobiles 
were developed in advance of the tractor, it has been easy for almost 
anyone to buy a motor and mount it on wheels and call it a tractor. 
Hut there is a great deal of difference between such an assembled 
machine and a tractor where the motor and every other part were designed 
especially and exclusively for tractor use. It is easy enough to assemble a 
machine using a stationary gas engine or automobile motor, but when put 
to actual tractor use the faults of such motors at once begin to show up. 

THERE ARE FOUR TYPES of motors used in tractors the single cylinder, 
twin cylinder, automobile type and opposed motor. We will discuss here 
all four kinds of motors and show why Avery opposed special tractor motors 
are superior. 

THE SINGLE CYLINDER MOTOR. It is not necessary to spend much time 
in discussing the disadvantages of the single cylinder stationary gas engine 
when used as a tractor motor. It is entirely too heavy for the power it 
develops. It is unbalanced, which makes necessary the use of counter- 
weights on the crankshaft, and even with them it is impossible to vary the 
speed to any great degree. 

THE TWIN CYLINDER MOTOR. This type of motor is no more nor less 
than two stationary gas engine cylinders placed side by side. It has the 
same faults as the single cylinder engine it cannot be made to balance and 
run at greatly varied speeds, which is necessary in a successful tractor. 
Furthermore, the placing of the two cylinders side by side makes the motor 
wider than it should be for the best mounting in a tractor frame. 

THE AUTOMOBILE TYPE MOTOR. The automobile type motor was built 
to be carried on spring mounted axles and pneumatic rubber tires it was 
not built to stand the shocks of rigid axles and solid steel tires or to pull 
a heavy load behind, as is required of a tractor motor. Again, an auto- 
mobile motor was not built to develop regularly anywhere near as large a 
percentage of its power as is required in a tractor motor. An automobile 
motor must develop an average of only about 25 to 33 1/3% of its rated 
horsepower, while a tractor motor must develop up to 80% of its horse- 
power almost steadily for hours afc a time. One authority says, "An auto- 
mobile motor running on low gear up a heavy, sandy grade is not operating 
under as severe conditions as a tractor motor in ordinary plowing." 

BESIDES ITS LACK OF STRENGTH, an automobile motor does not have 
the proper design to mount in a narrow tractor frame and combine with the 
proper kind of tractor gearing. The straight or spur gear type of trans- 
mission is generally conceded to be the best transmission for use in a 
tractor. It is also generally conceded that a tractor should be as narrow 
in width as possible. If an automobile motor is placed crosswise of the 
frame in order to use the straight spur gear type of transmission, it necesr 
sarily, because of its length, makes the tractor too wide. If an automobile 
type motor is placed lengthwise of the frame in order to narrow up the 
tractor, it is necessary to use some other form of transmission than all 
straight spur gears in order to turn the power at right angles. When an 
automobile type motor is \ised, it is necessary to sacrifice either one or the 
other of these two important features in a tractor narrow width or straight 

All Avery Motors are of the Valve 
in the Head Type 

THE VALVE IX THE HEAD TYPE MOTOR is admitted to be the most 
powerful and economical type of all. The full explosion of the gas drives 
directly against the head of the piston instead of part of the power and fuel 
being wasted in valve chambers, as in the case of the T and L-head motors. 
The cylinder heads on an Avery Tractor are easily removable and the valves 
readily ground. 

spur gear transmission the tractor is bound to be too wide or it is neces- 
sary to use some other form of transmission to turn the power at a right 

AVERY OPPOSED MOTORS are the only type which combine all the four 
necessary features of the most successful tractor motor first, balance; 
second, slow speed; third, narrow width; and fourth, strong construction. 

AVERY OPPOSED MOTORS are perfectly balanced and possess the import- 
ant feature which single cylinder and twin cylinder motors lack. They also 
run at low speeds only from 500 to Gf>0 revolutions per minute and thus 
possess the important feature of low speed which automobile motors lack. 

THESE TWO FEATURES of perfect balance and slow speed which opposed 
motors alone possess, make this type the most successful as a combination 
traction and belt power motor. A balanced motor is plainly superior for 
either traction or belt work, as it does not shake the tractor to pieces and 
delivers a constant steady stream of power. Low speed means long life, 
less wear and greater economy, it means less gears in the transmission to 
reduce the power to the low speed which a tractor travels, it means a larger 
belt pulley with more grip to the belt, a greater variation in speed to meet 
the constantly changing loads in belt work, and a longer, harder pull with- 
out "killing" under a heavy load. 

AVERY OPPOSED MOTORS are much stronger in construction than the 
automobile type motor and are able to stand up under the severe strains of 
traction work. Furthermore, the cylinders overlap one another, as will be 
seen in the illustrations, and hence the motor is very narrow. This is the 
reason why it is possible to combine in the Avery Tractor these two neces- 
sary features narrow width and all straight spur gear transmission. The 
opposed motor lends itself most successfully in its shape and construction 
to the requirements of tractor purposes. The illustration on page 28 of 
the top view of an Avery Tractor shows how the Avery opposed motor com- 
bines with a narrow frame and* a straight spur gear transmission as no 
other type of motor does. 

IT IS ESTIMATED by Government authorities that the work required of a 
tractor is equally as great for belt as for traction work. A tractor motor is 
the only kind called upon to perform a combination of traction and belt 
work. The single cylinder motor meets the requirements very well for light 
belt work the automobile type motor is successful for fast traction work 
but the Avery opposed special tractor motor is much the most successful In 
meeting the requirements of heavy belt work and low speed heavy traction 
work such as a tractor must perform. 

Avery Crankshafts are Mounted 
on Adjustable Bearings 

YOU CAN SEE HERE CLEARLY the construction of the Avery adjustable 
crankshaft bearings. The upper bearing is subject to very little wear and, 
as the lower bearing wears, adjustments to take up the wear can be easily 
made by the set screws, saving the trouble and expense of rebabbitting the 
bearings. The side of the crank case above the adjustable bearings is re- 
movable, as is also shown here, and the crankshaft can be removed if desired 
without having to separate the two halves of the crank case.

All Avery Tractors Will 
Burn Kerosene or Distillate. 

Avery Fuel System 

(The Second Unit in a Tractor) 

Avery's are the Tractors Which Burn All the Kerosene the Patent-Applied-for 

Avery Gasifier Does the Trick 

WE HAVE DISCOVERED the way to burn kerosene more successfully than it has ever been done before. 
WE BURN THE KEROSENE that other so-called kerosene tractors waste. 

WE USE LESS KEROSENE by gasifying it all instead of part going past the pistons and being wasted on account of not 
being fully vaporized. 

WE GET AS MUCH POWER out of a gallon of kerosene as the old style so-called kerosene burning tractors get out of a 
gallon of gasoline. 

WE BURN KEROSENE without the troubles previously experienced in burning this fuel, such as fouled spark plugs, pitted 
valves, carbon in the cylinder, pre-ignition, etc. 

WE BURN KEROSENE so successfully that we are able to use a closed crank case and gear pump oiling system, which is 
much superior to the mechanical oilers which builders of so-called kerosene tractors use to prevent the kerosene which 
passes their piston rings diluting the oil and causing the crankshaft bearings to be cut out. 

WE BURN KEROSENE successfully with a long manifold so that we are able to use an opposed perfectly balanced motor, 
while others are forced to use unbalanced twin motors with short manifolds in order to burn kerosene even as well as 
they do. 

THE SECRET of all these wonderful results is found in the Avery fuel system, consisting of an air heater, fuel heater, 
double carburetor, duplex gasifier, cold air inlet and water spray. 

AVERY TRACTORS don't just run on kerosene they burn all the kerosene. 

How Avery Tractors Burn All the Kerosene 

FIRST OF ALL, the fuel pipe passes through the exhaust side of the gasifier and the kerosene is heated on its way to the 
carburetor. An air heater is also provided for heating the air as it is drawn to the carburetor, whenever the weather con- 
ditions make it desirable. This fuel heater and air heater are both shown in the illustrations here. 

ALL AVERY TRACTORS are equipped with double carburetors. One bowl is for gasoline and the other for kerosene. The 
motor is started on gasoline and when it warms up you pull the lever and instantaneously switch over to kerosene without 
having to make a single adjustment of any kind. This double carburetor is the first special feature of the Avery fuel 
system. See illustration above. 

BUT WHILE A CARBURETOR will mix gasoline with air and form a gas which bums readily in the cylinder, no car- 
buretor has yet been designed which alone will successfully handle kerosene. In the Avery fuel system we accordingly place 
on each cylinder head our duplex gasifier, which takes the mixture of kerosene and air as it comes from the carburetor and 
so reduces the particles of kerosene and mixes them with the air as to form a gas that burns more successfully than 
kerosene has ever burned before. 


WE THEN PROVIDE an auxiliary air inlet and water spray which can be used 
when needed for tempering this gas to the proper degree to get the most power 
out of it. 

THE ILLUSTRATION AT THE RIGHT shows a cross section view of an Avery 
gasifler. A thin wall separates the exhaust and intake chambers. This wall 
is heated to a high degree by the heat of this exhaust. The mixture made by 
the carburetor is drawn into the intake chamber of the gasifier, which is so 
shaped that by centrifugal action the heavier particles are thrown against the 
hot wall and if not instantly gasified are held in suspense until they are fully 
turned into gas. 

ANY LACK OF THOROUGH VAPORIZING on the part of the carburetor or any 
condensation of the vapor in the manifold is thus taken care of by the Avery 
gasifier. which is attached directly to each head of the motor and which 
thoroughly gasifies the mixture and delivers it immediately into the cylinder in 
a form which makes it possible for Avery Tractors to burn all the kerosene. 

The 1917 Tractor Demonstration Proved Avery 
Tractors to Be Real Kerosene Burners 

THERE IS A LOT OF DIFFERENCE between the way different makes of 
tractors burn kerosene. 

SOME JUST "GET BY" others really "make good." 

AN AGRICULTURAL ENGINEER, who is an authority on tractors, writes, in 
reporting on the 1917 National Tractor Demonstration. "Some of the kerosene 
burners appeared to get along without any trouble, where others, judging from 
the smoke, looked as though they were burning soft coal. To be painfully 
exact and truthful, I may say that there are mighty few successful kerosene 
burning motors." Another authority says, in reporting on the demonstration, 
"Unfortunately there was no final checking up on the amount of kerosene 
passing the pistons into the crank case on any of the machines." 

THE RULES OF THE DEMONSTRATION were that a tractor which burned 
kerosene was allowed only 5% as much gasoline as kerosene for starting. All 
tanks were drained, filled and sealed under the supervision of a fuel inspector. 

THE AVERY COMPANY accepted the rule gladly as an opportunity to show 
that Avery Tractors were real kerosene burners. The tanks on every Avery 
Tractor were filled with kerosene, and every day of the entire demonstration 
every Avery Tractor proved that it was a real kerosene burner. 

Avery Tractors Did More Than Just 
Burn Kerosene 


They burned kerosene without calling for any more gasoline during the 

entire week than the 5% allowed for the first day's filling of kerosene. 
They burned kerosene without a lot of black smoke coming out of the 

exhaust showing that they did not waste fuel, but burned all of it. 
They burned kerosene without the fuel passing the pistons and cutting the 

lubrication the oil in the crank case did not have to be changed. 
They burned kerosene without wasting oil as do tractors with mechanical 

oilers where the oil is used only once. 
And to show that Avery Tractors would do even more, two sizes were run 

on distillate. 

Owners of Avery Tractors Burn Kerosene 

AVERY TRACTORS are making records in the field burning kerosene as well as 
at demonstrations and exhibitions. Read below what owners say. 

"Our engine runs as smoothly on kerosene as on gasoline. We haven't 
had a bit of trouble with it." J. D. Steele, Daviess Co., 111. 
"Am using kerosene all the time except for starting, and it works just as 
well with it as with gasoline." Wm. F. Schroeder, Renville Co., N. D. 

"There are eleven gas and oil tractors in our county. None of them 
handles kerosene as well as the Avery." Hosea O. Stoner, Hancock Co., 

"Am using my Avery Tractor plowing every day and it is giving the best 
of service with pure kerosene." Geo., R. Squire, Wood Co., Ohio. 

"Our Avery Tractor burns kerosene as good as any other make of tractor 
burns gasoline." J. W. Eggleson & Sons, Bates Co., Mo. 

"The Avery Tractor sold me last fall is the only successful tractor burning 
kerosene in this territory." Fred Caves, Jackson Co., Okla. 

Running on Kerosene is One Thing 
Burning All of it is Another 

IT IS A BIO STEP IN ADVANCE from burning gasoline to burning kerosene, 
but it is just as much or more of a further step from burning kerosene (as 
most any tractor can do for a little while) to burning all of the kerosene, as 
do Avery Tractors. 

AVERY TRACTORS arc the only make of tractors with a Double Carburetor 
and Duplex (iaxifier Fuel System, and the only make of tractors that really 
burn all the kerosene.

Cylinder Wall May 
be Removed. 

Pull Out This Inner Cylinder Wall 

A VERY SPECIAL FEATURE of Avery motors is 
the fact that they have renewable cylinder walls. 
The inner cylinder wall is cast separately from the 
main cylinder. Just consider what this renewable inner 
cylinder wall means. 

First, should you have any trouble, such as scoring from lack of lubri- 
cation or from any other cause, you can easily and quickly take out the 
inner cylinder wall and replace with a new one at very small cost. With 
other tractor motors, should you have trouble of this kind there is just one 
of two things to do either take out the motor, crate it up, ship it back to 
the factory where it was made, get it rebored, reground and an oversized 
piston turned up and fitted, or throw it to one side and get a new cylinder, 
either of which is a pretty expensive proposition, and, more than that, is 
certain to delay you seriously in doing your work. 

12-25 H. P. Tractor Crankshaft. 

Avery Tractors Have Practically 
Unbreakable Crank Shafts 

The smallest Avery crankshaft is 2 % inches in diameter and the largest 4 V 2 inches. The 
diameter of an Avery crankshaft is one-half or more than the diameter of the cylinders. The 
diameter of each bearing is the full size of the crankshaft and the length nearly equal to or even 
longer than the diameter of the cylinders. Furthermore, on account of using opposed cylinders. 
Avery crankshafts are also shorter, which increases their strength. The size of the Avery crank 
shaft, together with the wide bearings and the shortness of the shaft, are the reasons why an 
Avery crankshaft is practically unbreakable. The breakage of a crankshaft is one of the most 
serious things that can happen in any machine and a little investigation on your part will show 
you that it is an occurrence which quite often happens with some tractor motors. 

25-50 H. P. Tractor Crankshaft. 

Second, all things wear out in time, and when an Avery cylinder wall 
has become worn it can be removed and replaced with a new one by you in 
your own shop, or right in the field, and your motor made just as good as 
the day it left the factory. 

Third, if the water which you use for cooling contains sediment which 
collects on the inside of the cylinder, you can remove the Avery inner 
cylinder wall and clean the scale off by scraping it, and thus insure the 
motor being cooled perfectly at all times. 

ner cylinder walls is in itself one of the strong reasons 
why so many men are buying Avery Tractors when one 
fully appreciates the advantages of this feature, he will 
not consider having anything else.

Avery Oiling System 

(The Third Unit in a Tractor) 

AVERY TRACTORS are equipped with gear pump oiling systems. They 

/\ have few parts and the oil pipes are large. Mechanical oil pumps, 

* * which are used by many, mean pipes for each bearing and a pump 

for each pipe with small holes in the pipes to clog up and many parts 

to cause trouble. All this is eliminated in an Avery Tractor. 

THE ABOVE ILLUSTRATION shows the Avery Oiling System in detail. 
The surplus oil is carried in the lower part of the crank case. It flows 
down through a strainer to the gear pump, which forces it up the pipe into 
the sight feed glass bottle. It then flows down through the pipes to the 
openings just above each crank, out of which it pours in a steady stream, 
lubricating the crankshaft bearings, and is then thrown by the motion of 
the cranks into the cylinders and lubricates them. A cork gauge shows 
the operator the exact level of the oil in the crank case at all times and the 
glass sight feed enables him to be sure that there is a constant flow of oil. 

Avery Ignition System 

(The Fourth Unit in a Tractor) 

EACH AVERY TRACTOR is regularly supplied with a high tension magneto 
with an impulse starter. With the impulse starter the motor can be started 
off the mairneto. The high tension magneto eliminates batteries, coils, 
switches and a large amount of wiring, which are the parts that cause most 
of the trouble with ignition systems. 

Avery Cooling System 

(The Fifth Unit in a Tractor) 

IN THE COOLING SYSTEM on an Avery Tractor we use the thermo-siphon 
system, in which the heat of the water causes its own circulation. No cir- 
culating water pump Is used on Avery Tractors and thus all wearing of 
gears, packing of pumps, draining, freezing and such other troubles are 
done away with* 

FURTHERMORE, by the construction of our radiator we do away with the 
fan and use the exhaust to draw the cool air past the tubes, which saves 
the power required to drive a fan, as well as doing away with the fan, fun 
belt and pulleys, which are trouble makers and make a tractor more 

THE RADIATOR itself is round and made of vertical copper tubes. It is 
open on all sides. The air will strike the radiator no matter from what 
direction it is blowing, while with the styles of radiators open only in front, 
the wind does not blow on the tubes unless coming in just the right 
direction. |

Avery Direct Drive Transmission and Patented Sliding Frame 

TRACTORS drive direct from the crankshaft in both high and 
low speed gear and in belt driving. 

' AS YOU WILL SEE by the above illustration, the belt pulley and 
the high and low speed pinions are all on the crankshaft. 

ALL THE POWER of an Avery motor is delivered to the belt, on account 
of the belt pulley being on the crankshaft. There is no train of gears 
between the crankshaft and the belt pulley through which the power must 
be transmitted in belt driving. No power is wasted and no gears are worn 
out when you use an Avery Tractor in the belt. 

THE AVERY DIRECT DRIVE from the crankshaft in both high and low 
speed gear is made possible by the patented Avery sliding frame. Both the 
high and low speed pinions mesh directly into the compensating gear without 
any intermediate gear. The traction power lost in other tractors through 
an intermediate gear contact is saved in an Avery Tractor and delivered to 
the draw-bar, and there are less gears, shafts and bearings to wear out. 

BECAUSE OF THE AVERY SLIDING FRAME, -which makes possible the 
elimination of the intermediate gear, intermediate shaft and bearings, Avery 
Tractors also have the least gears, the least shafting and the least bearings 

of any two-speed double drive tractors built. Only six gears are used in 
forward drive. Avery Tractors have only one countershaft and only five 
transmission bearings. 

ANOTHER ADVANTAGE in the Avery Transmission is that Avery Tractors 
have all straight spur gears. The spur gear type of transmission is the 
type which years of steam engine experience developed as being the most 
successful transmission for heavy traction work. The chain drive trans- 
mission was used on steam engines and discarded. The bevel gear trans- 
mission was used on steam engines and discarded. Both proved to be 
inefficient as the means of transmitting power for heavy traction work. 
The spur gear type, such as used on Avery Tractors, has proved to be the 
type of transmission which delivers the power to the rear wheels with the 
least loss and stands up under heavy traction work. 

NO OTHER TRACTOR has a combination of all of these superior trans- 
mission features -direct drive from crankshaft to belt direct drive from 
crankshaft to both high and low speed gears all straight spur gears and 
such a small number of gears. The combination of all of these features 
which you get in an Avery Tractor is made possible by the patented Avery 
Sliding Frame. 

Take Hold of This Lever and 
Slide the Frame 


THIS PATENTED SLIDING FRAME does away with the intermediate gear 
shaft and bearings, and is the reason why an Avery Tractor has the least 
gears, the least shafts and the least bearings of any double drive, two-speed 
tractor built (In this view the low speed pinion is in mesh with th 
compensating gear for traveling ahead. See illustrations on next pages 
shmving operatirn of sliding frame and two-speed gears.)

The Patented Avery Sliding Frame and 
How It Operates 

THE WONDERFUL SIMPLICITY of the gearing and shafting on Avery 
Tractors is made possible by the use of a patented sliding frame as shown 
in the illustration on the opposite page. 

IN THE AVERY TRACTOR the entire power plant is mounted on a sliding 

WHEN TRAVELING AHEAD on low gear the low speed crankshaft pinion 
meshes directly into the compensating gear no intermediate gear is used. (See 
side and top views of gearing No. 1, above and below.) 

FOR BELT WORK, backing up, or high speed, the sliding frame is pushed 
forward until the low speed crankshaft pinion is disengaged from the compen- 
sating gear. 

WITH THE CRANKSHAFT PINION disengaged from the compensating gear, 
you are in position for belt driving. (See side and top views of gearing No. 2, 
above and below.) 

IF YOU WISH TO TRAVEL AHEAD in high gear, slide the high-speed pinion 
over to engage the compensating gear. (See side and top views of gearing No. 3, 
above and below.) 

IF YOU WISH TO BACK UP, draw back the reverse gear to engage both the 
crankshaft pinion and the compensating gear. (See side view of gearing No. 4, 
at right.) 

gear is required for traveling ahead and the intermediate shaft and bearings are 
done away with, thus eliminating loss of power by the friction of the extra gear 
and shaft, decreasing the dead weight to move around and reducing the expense 
of wear and breakage.

Top View of an Avery Tractor, Showing the Two Speed Geir on the Crank- 
shaft and the Double Drive to Both Rear Wheels. Alco Note How the 
Avery Opposed Motor Makes Possible the Use of Both a Narrow Frame and 
an All Spur Gear Transmission. 

All Avery Tractors Have Two- 
Speed Gears 

THE SLIDING FRAME on an Avery Tractor makes possible the 
simplest two-speed gear on any tractor. The low-speed gear 
is double the width of the compensating gear and the high-speed 
gear slides back and forth over it. No gear box, third crankshaft 
bearing or double ring gear are necessary for speed changes. 

FURTHERMORE, AVERY TRACTORS are direct drive on both 
high and low gear. Both gears when in mesh are directly against 
the crankshaft bearing, thus making a third crankshaft bearing or 
double ring gear unnecessary. 

THE COMBINATION SLIDING FRAME and sliding gear con- 
struction on an Avery Tractor is unquestionably the most simple and 
successful two-speed gear made. The advantages of having a two- 
speed tractor with a low speed for plowing and other work and a fast 
speed for light work and traveling on the road does not need to be 
discussed to be fully appreciated by anyone. 

All Avery Tractors Have Double 
Gear Drives 

AVERY TRACTORS have two rear wheels o equal size 
and are geared to both rear wheels. 

A NUMBER OF ATTEMPTS have been made to build 
tractors with single drives. All of them, however, have 
developed serious faults. 

WITH A DOUBLE DRIVE there is no constant twisting 
strain on the frame. With a single drive the power de- 
livered at the draw-bar is determined by the ability of the 
frame to resist being twisted and the weight of the tractor 
to resist being tipped over. Many single drive tractors 
have shown that they will tip over very easily, especially 
when pulling a load and turning a corner. 

WITH A DOUBLE DRIVE a tractor can be turned 
short either way, as the compensating gear will enable 
either drive wheel to travel faster than the other in turn- 
ing a corner. Where a single drive is used, it is difficult 
to turn in a short circle in both directions. If the drive 
wheel is located on one side of the frame, with a balancing 
wheel opposite to it, the only way you can turn to the 
right is by forcing the front wheel into the ground 
sufficiently to slide the drive wheel around on the ground. 
If there is only a single drive wheel behind and two front 
wheels, you cannot turn either to the right or to the left 
except by forcing one or the other front wheel into the 
ground and thus sliding the drive wheel around. Remem- 
ber, also, that in plowing you must turn to the right prin- 
cipally, and that is just the direction in which single drive 
tractors find it difficult to turn in a short space. 

A DOUBLE DRIVE also makes a strong, durable trans- 
mission for traction work much stronger and longer 
lived than any single drive can possibly be. 

THE SINGLE DRIVE construction, therefore, has these 
three principal faults: There is a constant tendency to 
twist the frame or tip over it; it is difficult to turn short; 
and the single drive lacks durability. A double drive, as 
used on all Avery Tractors, eliminates all frame twisting, 
makes it possible to turn short either way, and is strong 
and durable for heavy traction work. 


Other Advantages of the Avery 
Transmission and Frame 

used on Avery Tractors also make possible a narrow 
tractor, as will be seen by comparing the width of 
Avery Tractors with other makes. A narrow tractor 
means less side draft, less double travel on the ground in 
field work, shorter turning and being able to pass through 
narrower gates. The Avery Motor is also located cen- 
trally between the sides of the frame, giving an equal 
distribution of weight on both rear drive wheels. 

ALL AVERY TRACTORS have steel and semi-steel 
gears no cast iron gears are used. All Avery Tractors 
have revolving rear axles no stub axles are used. All 
Avery Tractors have the rear axle and countershaft bear- 
ings in one casting with oil wells in the center, thus mak- 
ing them easily oiled and keeping the bearings always in 
line no separate bearings are used for each end of the 

THE MESH OF ALL AVERY GEARS is adjustable for 
wear. The countershaft and rear axle are tied together 
with rods threaded on each end, making it possible to ad- 
just the mesh between the bull pinions and bull gears. The 
adjusting screws on the sliding frame also make it pos- 
sible to adjust the mesh between the crankshaft pinions 
and compensating gear. 

in the transmission easily accessible. There is no com- 
plicated speed change gear box. The compensating gear 
is on the outside of the frame and there is no third bear- 
ing on the crankshaft to be removed to get at the crank- 
shaft pinions. 

THIS COMBINATION of a spur gear transmission, 
sliding frame, two speeds and double drive, with all these 
advantages, is found only in Avery Tractors and has a big 
part to do with their unusual success. 

Avery Clutch 

(The Eighth Unit in a Tractor) 

ONLY ONE CLUTCH IS USED, on Avery Tractors. 
Many Tractors have two or even more. This is so de- 
signed that it serves for traveling ahead, reversing or belt 

THE AVERY CLUTCH has three clutch arms, on the 
ends of which are riveted Raybestos brake linings. It has 
a good grip on the belt wheel and yet will release easily. 
The shoes push straight out against the inner surface of 
the belt wheel and do not cause any end thrust on the 

THE BELT WHEEL on the Avery Tractor does not 
travel with the motor unless the clutch is engaged. This 
makes it possible to put the belt on the belt wheel and 
back into it, by slipping the clutch, much more easily than 
it is possible when the belt wheel is fast to the shaft and 
revolves at the motor's speed. Furthermore, the same 
lever which throws the clutch in, when drawn back, en- 
gages a brake on the outer surface of the belt wheel, by 
which it can be quickly stopped for engaging the gears or 
should any accident happen to the thresher, sheller, saw 
or other machine which is being driven. 

Avery Wheels 

(The Ninth Unit in a Tractor) 

AVERY TRACTORS have round, built-up steel wheels 
with flat spokes. They are cheaper in first cost, longer 
lived and require less repairs than any other wheel built. 

wheel tractors proved themselves able to travel anywhere 
the sprocket type of wheel would go. Avery Tractors will 
travel on any ground in fit condition to be worked. 

BOTH REAR DRIVE WHEELS on Avery Tractors, be- 
ing located outside of the frame, can be equipped with 
extension rims for traveling over very soft ground, while 
with drive wheels located inside of the frame, you are 
limited to traveling over the ground which will carry the 
regular width wheels, as it is impossible to attach exten- 
sion rims. One tractor owner has written us that he has 
found more places where he needed three drive wheels 
than where he could have gotten along with one, and with 
his Avery Tractor he can get what amounts to the width 
of three wheels by simply attaching extension rims to his 
two regular drive wheels. 

WE HAVE SPENT A GREAT DEAL of time and effort 
devising various forms of cleats, spuds and lugs to be used 
on Avery drive wheels to meet all conditions. We are in 
position to supply five types of lugs, as may be desired. 
All these are bolted to the drive wheel, making it also 
possible to have smooth drive wheels when wanted. See 
illustrations on page 34 of the various styles of wheel 
equipment we are in position to furnish. 

AVERY WHEELS are built-up steel with flat spokes 
riveted hot to the hubs and rims. This construction makes 
them extremely durable under hard traction work. 

THE QUESTION OF THE WHEELS on a tractor is a 
very important one, and we believe that you will find this 
question has been better solved on an Avery Tractor 
on any other make. 


Belt Wheel 


Why Avery Tractors are Reliable and Durable 

AWE HAVE SAID BEFORE, the success of any 
tractor is dependent upon the design of the nine 
units in the tractor motor, fuel system, ignition 
system, oiling system, cooling system, clutch, transmission, 
frame and wheels and the combination of these into a 
complete machine to produce these nine results relia- 
bility, durability, simplicity, light-weight, power, speed, 
economy, accessibility and ease of handling. 

ON THE PREVIOUS PAGES we have discussed the 
design of these nine units in an Avery Tractor now we 
will tell you how they are combined to produce these nine 

Why an Avery Tractor Stands Up 

So Well Under Hard Work 

and is So Long Lived 

THE FIRST TWO RESULTS of the successful com- 
bination of the nine tractor units in an Avery Tractor 
have been to secure an unusual degree of reliability and 
durability. These are the points of first importance in 
buying a tractor. How much a tractor is worth depends, 
first of all, upon how well it will stand up under the work 
and how long it will last. 

IN AN AVERY TRACTOR the nine individual units are 
so designed and combined as to produce a tractor that 
runs steady and is built to last. 

motor makes an Avery Tractor extremely reliable and 
durable. It is of the opposed type, which makes possible 
an extra strong construction. It runs at a low speed only 
around 500 revolutions per minute which means that 
there is little wear on the parts. Being of the opposed 
type, no balancing counterweights are required on the 
crankshaft, which are a constant source of trouble and re- 
pair expense with many makes of motors. It balances 
perfectly and prevents the great vibration found in many 
tractors, which is constantly jerking them to pieces. 
Watch an Avery Tractor and see how still it stands and 
then watch the others and you will appreciate this fact. 
In the Winnipeg Motor Contest Avery Tractors were first 
in lackrof vibration in all four classes in which they were 

AN AVERY TRACTOR is so perfectly balanced that our 
customers often stand nails on their heads on the frame 
when the motor is pulling a full load, to show how little 
vibration there is. 

THE ELIMINATION of the fan, fuel pump, water pump 
and lubricator also does away with a lot of delicate parts 
that often break and cause trouble on other tractors. 

THE CLUTCH on an Avery Tractor is large and strong 
and of the type which has shown itself to be the most 
durable for heavy traction work. 

THE ALL SPUR GEAR TYPE of transmission as used 
on Avery Tractors has proven itself to be the most 
reliable and durable type for heavy traction work. 

FURTHERMORE, no ordinary cast iron gears are used 
on Avery Tractors. A combination of steel and semi-steel 
gears is used. We have found that this combination of 
gearing wears much longer than all steel and by using a 
high grade quality of material, we are able to produce 
semi-steel gears that for tractor use are almost as un- 
breakable as all steel. The best proof of this is that we 
have comparatively little call for gear repairs. 

A STRAIGHT SPUR GEAR TYPE of transmission, with 
the fewest gears of any, together with a combination of 
steel and semi-steel, are the reasons why the transmission 
on an Avery Tractor causes so little trouble and is so 
long lived. 

THE CRANKSHAFT on an Avery Tractor is extremely 
large in diameter. It is short in length. It is made from 
forged steel. It is mounted in wide bearings. The coun- 
tershaft is cold rolled steel and revolves in a solid bab- 
bitted box. The rear axle is a cold rolled steel shaft and 
also revolves in a solid babbitted boxing. We do not use 
stub axles as do many. The countershaft box and rear 
axle box are not only bolted solid to the frame, but special 
rods are provided for holding these positively at the cor- 
rect distance apart to give the proper mesh to the gears. 
Remember, also, that because of the Avery sliding frame, 
an intermediate shaft and bearings are unnecessary. Large 
shafting, wide bearings, and fewer shafts and bearings 
than on other tractors, are further reasons for the 
unusual reliability and durability of Avery Tractors. 

THE WHEELS are built-up steel with flat spokes. The 
rear wheels on the larger sizes have reinforcements rolled 
from the solid stocl> on the inside outer edges of the rims. 
This is the longest lived wheel construction known. 

THE MAIN FRAME on an Avery Tractor is a combina- 
tion of channel steel bars and angle bars. The Avery 
frame has proven to be of absolutely dependable and 
durable construction. 

ALL THESE FEATURES a strong opposed motor with 
a large crankshaft and wide bearings, the strongest type 
of clutch known for traction work, a straight spur gear 
transmission, all steel and semi-steel gears, a revolving 
rear axle and strong wheels and frame all these make up 
a combination that results in unusual reliability and dura- 
bility and are the reasons why an Avery Tractor stands 
up so well under hard work and is long lived. 


Why Avery Tractors Are Simple and Light Weight 

The Facts Which Prove That 

Avery Tractors are the 

Simplest Tractors Built 

THE THIRD RESULT of the successful combination 
of the nine tractor units in an Avery has been to 
produce a tractor that is the simplest tractor built. 
And we don't simply stop with making this claim 
we give you below the facts to back it up. 

AN AVERY TRACTOR has a simple opposed motor with 
no counterweights on the crankshaft to come loose and 
tear the motor to pieces. No heavy flywheel is required 
for keeping up the momentum. There are but two bear- 
ings on the Avery crankshaft instead of three or more as 
on many others which increase friction and make it more 
likely for the boxes to wear and cause the crankshaft to 
bind and spring out of line. 

AN AVERY TRACTOR has no fuel pump to leak and 
require packing or to break. The fuel is fed to the 
carburetor by gravity. 

AN AVERY TRACTOR has no troublesome clockwork 
lubricator to get out of order or to clog up and cause the 
motor to overheat. 

AN AVERY TRACTOR has no cooling fan to waste 
power or cause trouble the exhaust draws the cool air 
past the tubes for cooling. It has no fan belt to get loose 
or break. 

AN AVERY TRACTOR has no water pump to leak and 
require packing or to freeze and cause delays and expense. 
The thermo-siphon system of water circulation is used 
and the pump eliminated. 

AN AVERY TRACTOR has no fan belt, no governor 
belt, no pump belt and no sprocket chains to break or 
wear out. 

AN AVERY TRACTOR has the fewest gears of any two- 
speed double drive tractor no intermediate gear is used 
in traveling ahead the crankshaft pinion meshes directly 
into the compensating gear. Only six gears are used in 
traveling ahead. There are but two gear contacts crank- 
shaft pinion to compensating gear and bull pinion to bull 
gear. There are no idle gears in mesh and running, either 
when belt driving or pulling. 

AN AVERY TRACTOR has no intermediate shaft there 
are but two main engine shafts, crankshaft and counter- 
shaft. It has no intermediate shaft bearing. There are 
only five transmission bearings. 

NO SUCCESSFUL TRACTOR ever has been or, we be- 
lieve, ever can be designed with less gearing and shafting 
than are used in an Avery Tractor. 

AN AVERY TRACTpR has but one friction clutch, 
which serves for traveling forward or backward or when 
working in the belt. This saves a lot of unnecessary parts. 

AN AVERY TRACTOR has no counterweights on the 
crankshaft, no fuel pump, no clockwork lubricator, no fan, 
no water pump, no intermediate forward gear, no inter- 
mediate shaft, no intermediate shaft bearings, only one 
clutch. Claims of simplicity are sometimes made with- 
out being backed up. These facts prove that Avery 
Tractors are the simplest tractors built. 

The Lightest Weight Tractors 

Built Considering Their 

Draw-Bar Efficiency 

LIGHT WEIGHT is the fourth result of the successful 
combination of the nine units in an Avery Tractor. But 
do not confuse the meaning of the word light-weight with 
the question of size and think that Avery "Light-Weight" 
Tractors mean only our small size tractors. Every Avery 
Tractor is built "Light-Weight," from the small 8-16 
H. P. size to the large 40-80 H. P. size. 

WHEN WE SAY "LIGHT-WEIGHT" per draw-bar 
efficiency, we mean that Avery Tractors are the Lightest 
Weight of any, considering the power they deliver at the 
draw-bar and their ability to keep it up. Weight must be 
considered in connection with both power and strength of 
construction to mean anything. It's easy to build a 
"Light-Weight" Tractor, but the hard thing is to build a 
Tractor that is Light-Weight for its power and also has a 
strong enough construction to stand up in the field, year 
in and year out. 

the_ Lightest Weight Tractors built, considering both 
their power and their strength of construction. 

The Advantages of the "Light- 
Weight" of Avery Tractors 

AN AVERY "LIGHT-WEIGHT" TRACTOR doesn't waste fuol or nower 
moving useless dead weight. It's an absolute waste of power and money 
to move around all day the tons of surplus iron and steel found in heavy 
weight tractors. For every surplus ton of weight in a tractor you can figure 
a waste of about the power of one good farm horse. In other words, this 
means that if you have from 2 to 3 tons of surplus weight in a tractor to 
move around you will have to waste about enough power to pull one extra 
plow, which means so much less work. You can also figure that for every 
unnecessary ton of weight it takes about 2 gallons of fuel per day to move 
it around. And all of this waste of power and fuel is all for nothing. It is 
not necessary to have this extra weight to make a strong and durable tractor. 

AN AVERY "LIGHT-WEIGHT" TRACTOR won't pack your ground to 
injure your crop. The pressure of an Avery Tractor wheel on the ground 
is much less per square inch than the pressure of a horse's foot. 

WITH AN AVERY "LIGHT-WEIGHT" TRACTOR you can get into the field 
earlier in the spring or after a rain. Reliable reports state that owners of 
hundreds of the "Heavy- Weight" Tractors have to let them stand idle in the 
spring because they can hardly move themselves, let alone pull plows and 
other machinery. One letter says that one-half of the tractors in a certain 
locality were idle. At the fairs Avery "Light-Weight" Tractors have 
followed behind the "heavy-weights" and plowed right along over ground 
where the "heavy-weights" mired down or had to unhitch from their plows. 

AN AVERY "LIGHT-WEIGHT" TRACTOR will work on any ground that Is 
in condition to be worked with horses or mules. The best possible evidence 
of this is reports from actual users of Avery "Light-Weight" Tractors. Here 
are samples: "The tractor is working fine so far and could not be beat on 
this soft marsh. We can use it where horses mire; in fact, we crossed 
places without the least trouble where it would not be safe to cross with a 
team of horses." "I want to tell you what I have been doing with my 
tractor pulling a binder cutting rice where the ground was so soft that 
mules could not go and pull the binders." "From my experience there is 
no danger of tractor wheels packing ground when drilling, for my Avery 
Tractor is not the heavy kind." "Owing to their light weight in comparison 
to the power they develop, they do not pack the ground any more than 


WE CANNOT EMPHASIZE the advantages of this "Light-Weight" feature 
of Avery Tractors too strongly. It means these most important things to 
you saving expense because of not wasting fuel moving around useless 
dead weight more work because no wasting of power no packing your 
ground to injure your crops and being able to do your work whenever the 
ground is in condition to be worked. 

REMEMBER that Avery "Light-Weight" Tractors are the Lightest Weight 
Tractors built considering their draw-bar efficiency and durability. 


Why Avery Tractors are Powerful and Speedy 

You Get a Fine Combination of 

Power and Speed in an 

Avery Tractor 


the successful combination of the nine units in an 
Avery Tractor. 

POWER AND SPEED must, of course, be considered 
together. Everybody knows the law of physics that when 
you increase speed you lose power, and when you decrease 
speed you increase power. 

SOME MANUFACTURERS build tractors with a low 
speed and then talk about the large number of plows their 
tractors pull when, if you compare their speed in the field 
with others, you will find that they actually turn over less 
ground in a day's time than tractors pulling less plows. 

unusually fast speed. It's easy enough to build a tractor 
that way, but a race horse tractor isn't any more fitted for 
farm work than a race horse animal. 

that Avery Tractors have two speeds, and that the low 
speed is not too slow and the fast speed not too fast. 
They are all built to pull a maximum number of plows on 
slow speed or a lesser number on high speed as the condi- 
tions of the ground make advisable or as the operator 
may prefer. 

Why Avery Motors Develop an 
Unusual Amount of Power 

AND NOW WE WANT TO TELL YOU also why it is 
that Avery Motors develop an unusual amount of power 
and why more of this power is delivered to the draw-bar 
than in any other tractors. 

large amount of power they do is because, in the first 
place, we use motors of large dimensions, considering the 
size tractors in which they are used; in the second place, 
we use a valve in the head type motor; and in the third 
place, we use five piston rings which are closely fitted by 
careful hand filing into accurately bored cylinders. The 
large dimensions, the valves in the head, and the 5 piston 
rings, with extra good fitting, are the things which make 
Avery motors so powerful. 

Why More of the Power Devel- 
oped by the Motor is Delivered 
to the Draw-Bar in an 
Avery Tractor 

THE MOTOR in an Avery Tractor is placed lengthwise 
of the frame, which makes it possible to drive through 
straight spur gears, which deliver more of the power of 
the motor to the drive wheels than any other kind of 

transmission. Furthermore, because an Avery Tractor 
has no intermediate shaft and no intermediate gear is used 
in traveling ahead, the power lost by friction of these 
parts on other tractors is also eliminated. Engineering 
authorities say there is a loss of from 8% to 10% of 
power in every gear contact. The one less gear contact 
on Avery Tractors saves this power for use at the draw- 
bar, which in other tractors is lost in the transmission. 

WE HAVE ALREADY EXPLAINED in discussing the 
question of weight as to the heavy loss of power in mov- 
ing around the surplus tons of iron and steel found in 
heavy-weight tractors and how in Avery "Light-Weight" 
Tractors this power is saved for pulling at the draw-bar. 

IT HAS ALSO BEEN SHOWN that it requires about 
3 Brake H. P. on the average to drive the fan used on 
most tractors. This power is not wasted on Avery 
Tractors. No fan is used, the exhaust being piped in such 
a way as to draw the cool air past the radiator tubes. 

THESE FOUR FACTS are the principal reasons why 
Avery Tractors deliver a large amount of power in the 
belt or on the draw-bar. 

FIRST, Avery Tractors drive only through straight spur 
gears, which deliver more of the power of the motor to 
the drive wheels than any other transmission. 

SECOND, Avery Tractors have but two gear contacts, in- 
stead of three, as in the ordinary tractor construction, and 
thus save the power lost by friction of this extra gear 
contact and the friction in intermediate shaft boxings. 

THIRD, because Avery Tractors are "Light-Weight" 
their power is not wasted in moving around surplus un- 
necessary weight, but is delivered to the draw-bar. 

FOURTH, Avery Tractors save the power lost in driving 
a fan. 

POWER IS WHAT YOU WANT when you get a tractor. 
You get the full rated belt and draw-bar power when you 
buy an Avery Tractor. The motor develops more than 
the necessary amount of power and this power is not 
wasted in driving useless accessories, it is not used up in 
unnecessary friction of shafting and gearing, and it is not 
lost through having to move around a lot of surplus weight. 

AVERY TRACTORS are regularly equipped with a two- 
speed gear a low speed for plowing and other heavy work 
and a fast speed for light work and traveling on the road. 

THUS IN AN AVERY TRACTOR you get the full rated 
horsepower either in the belt or at the draw-bar; you get 
a tractor that doesn't waste its power in useless friction 
or in moving around unnecessary weight; you get a 
tractor that travels at a good rate of speed, and you have 
a different speed to use as you may need for the special 
work you are doing. 


Why Avery Tractors are Economical, Accessible 

and Easy to Handle 

Avery Tractors Have Demon- 
strated Themselves to be 
Unusually Economical 
in Fuel Consumption 


units in an Avery Tractor you get as the seventh 
result an unusual degree of economy. 

AVERY TRACTOR MOTORS have demonstrated them- 
selves to be unusually economical in fuel consumption, 
both in competitive tests and in the hands of users. 

THE REASONS for the greater economy of Avery 
Tractors, considering the work they do, are first, their 
ability to burn cheap kerosene or distillate successfully, 
and burn all of it; and second, the fact that less of this 
power is used in moving the tractor itself on account of 
the simple transmission and light weight. 

AN AVERY MOTOR is, first of all, of the valve in the 
head type, which is admittedly the most economical of all. 
Second, it has 5 cylinder rings for holding the compres- 
sion. Third, the inner cylinder wall of an Avery motor, 
being a separate casting, stays round better, which means 
better compression and increased power. 

THE FACT that in an Avery Tractor there is less loss 
of power in the transmission than in other tractors has 
been fully explained under the subject of Power and 
Speed, and it is not necessary to repeat it here except to 
point out that this fact not only means increased power at 
the draw-bar, but also that less fuel is required for doing 
the same amount of work. 

GASOLINE, kerosene, or motor spirits can be used in an 
Avery Tractor as desired. You can have the choice of 
burning whichever fuel is the cheapest in your locality, no 
matter what the price may be from year to year, a thing 
which you can never determine in advance. 

You Can Easily Get at Any Part 
of an Avery Tractor 

ACCESSIBILITY is the eighth advantage of the success- 
ful combination of the nine units in an Avery Tractor. 

THE CYLINDER HEADS are easily removable for 
grinding the valves. 

THE INNER CYLINDER WALLS are easily renewable 
in case of wear. 

REMOVING THE CAM CASE gives a wide opening for 
using wrenches in tightening the connecting rod boxes. 

THE VALVE RODS are adjustable from the outside. 

THE CRANKSHAFT BEARINGS are adjustable, which 
can be done easily with a socket wrench. 

THE GEARS are all located outside the frame and handy 
to get at. 

IN EVERY WAY POSSIBLE an Avery Tractor is de- 
signed to be easy to take care of and keep in good running 

It Doesn't Take an Expert 

to Run an Avery 


THIS IS THE NINTH and last important result of the 
successful combination of the nine units in an Avery 
Tractor ease of handling. 

AN AVERY TRACTOR is so simple that anyone who is 
able to handle the levers can easily operate it. 

EVERY AVERY TRACTOR is regularly equipped with 
pur special easy safety starting lever as shown in the 
illustrations of the complete tractors on the previous 
pages. This is by far the finest thing ever devised in the 
hand tractor starter line. The lever is permanently at- 
tached to the flywheel and rests in the hook on the side of 
the frame. To start the motor, the operator raises the 
lever to the position shown in the illustration. When he 
pulls down, the block on the lever presses against the rim 
of the flywheel and revolves the motor. This lever makes 
starting the motor wonderfully easy. It is even easy to 
turn the motor over with all the priming cocks closed. 

AVERY TRACTORS are built to turn around in an un- 
usually short space, which is of special advantage. In the 
steering device we use double cross chains with accurately 
shaped rollers so that the chains remain taut at all times. 

THERE IS MUCH LESS to cause trouble in operating 
an Avery Tractor than with many others no fan or fan 
belt to break, no fuel or water pumps to leak or clog up, 
no clockwork lubricator to choke up. 

ABOUT ALL THERE IS TO DO to run an Avery 
Tractor is to pour in the fuel, lubricating oil and water, 
and keep everything tightened up. It does not take an 
expert to run an Avery Tractor. It is simple and easy for 
an ordinary man to handle and keep in running order.

"Power -Lift" 
Tractor Plows 

IN ADDITION to having a complete line of 
tractors from which you can select a size to 
exactly fit your needs, we are also in position 
to supply you with the size plow you need in 
either light or heavy styles. You will find our 
heavy independent beam type shown on the 
two following pages and on these two pages 
our light combination tractor plows. 

here are built in four combination sizes i and 
2 2 and 3 3 and 4 and 4 and 5 bottoms. 

IF YOU HAVE a 2, 3, 4 or 5 bottom plow and 
find you can pull one plow less to better ad- 
vantage, you can detach the rear bottom and 
beam by removing five bolts and shifting the 
rear wheel and axle to the next plow. If you 
have a i, 2, 3 or 4 bottom plow and want the 
next larger size, you can add a beam and 
bottom. This combination feature is very 
valuable when you have varying conditions of 
plowing or when you desire to plow some fields 
at a greater depth than others. 

THESE PLOWS do first-class work and are 
easy to handle. The bottoms are guaranteed 
to scour in any soil where any other moldboard 
plows will scour.

Special Features of Our Combination Light 

Tractor Plows 

OUR COMBINATION PLOWS are all built with a 
special power lift device operated from the plow 
wheel. The Tractor operator has full control of 
the plows from his position on the tractor. One rope 
attached to one lever controls the simple positive clutch 
by which the plows are either raised or lowered. One 
pull of the rope and one-half revolution of the clutch 

raises the plows from the ground. Another pull of the 
rope and the plows are released and quickly take their full 
depth. It is not necessary to stop or slow up tractor 
when either dropping or raising plows. 

AT FURROW ENDS or at will of operator a pull of the 
string automatically lifts all plows five inches high. The 
cranking backward of the front wheels raises the front 
plows and an ingenious lever connection between power 
lift bracket and rear wheel attachment raises the rear 
plow five inches and levels all bottoms. This feature 
eliminates all chance for gathering trash on plow points 
and the annoyance and inconvenience incidental thereto. 

break pin prevents share breakage, and being rigidly 
fastened to the tractor permits of backing the plow. 

TWO LEVERS, within convenient reach of the operator, 
at the front of the plow govern the depth of plowing. 
Change of depth can easily be accomplished when plowing 
or when plow is in or out of ground, as both levers are 
always within easy reach of operator of the tractor. By 
these levers all of the plows may also be lifted out of the 
ground when plow is not in motion. The land lever re- 
mains stationary at all times, while the furrow lever 
travels about 30 forward when plows are raised from the 
ground. Plowing can be done to a depth of nine inches. 
The beams are extra heavy, made of high carbon steel, 
bent to provide ample clearance. 

SINGLE PLOWS SELDOM CLOG even when plowing 
the most trashy ground. Clogging usually occurs, if at 
all, between first and second or second and third plows. 
In these plows, not only is ample throat room provided for 
each bottom, but an unusual distance is allowed between 
beams for the turn of each furrow slice, which is most 

THE WHEELS ARE STRONG and of good height, with 
wide tires, equipped with long distance magazine boxes, 
with grease caps on the ends. A spring lock device on 

the rear wheel permits the wheel to swivel in turning at 
ends and automatically is locked into position when 

THESE PLOWS are built with either 12-inch or 14-inch 
bottoms. Regular equipment includes stubble or turf and 
stubble bottoms. These will interchange with breaker, 
rod breaker, black land or slat bottoms. 

STANDARD EQUIPMENT includes rolling coulters, 
weed hooks, scraper for rear wheel and tractor hitch. 
Special equipment includes chilled cast shares, fin cutters 
for breaker bottoms and jointers. 

THIS COMBINED CpULTER and Jointer consists of 
an ordinary coulter with a jointer blade so connected 
to the left hand fork of the coulter yoke that the blade 
will ride along the furrow side of the coulter blade and 
turn over a small furrow of soil, weeds, trash, etc., leaving 
the plow mouldboard an easy job of covering. 

THE JOINTER BLADE is adjustable on the standard 
and standard and blade are fastened to an adjustable plate 
attached to the coulter yoke so proper set of blade may 
be had to suit the working conditions. 

THE BLADE, made of hardened soft center steel for 
easy scouring, consists of two parts, and as the point is 
subject to the greater wear, it will only be necessary to 
buy this part of the blade to renew the jointer. If it is 
desired to use a jointer only without the coulter, the blade 
may be inserted on the regular 1^6-inch or 1^-inch 
coulter stem. Jointer point is regularly furnished with 
soft center steel point, but cast iron point will be furn- 
ished, if desired. 

FOR A GOOD JOB of covering under the most trashy 
conditions, this Combination Coulter- Jointer cannot be

Engine Gang. Showing the Double Straight Heavy Beams. 

Independent Beam Heavy 

"Self-Lift" Tractor 


IN THE AVERY Independent Beam "Self-Lift" Engine 
Gang, each plow is attached to the frame independent 
of the others. It is free to raise or lower according to 
the conditions of the ground and to follow its furrow 
without being affected by any other plow. If one plow 
strikes a stone or other object it does not affect any of 
the others. 

THE AVERY "SELF-LIFT" PLOW also has unusual 
strength. Each plow has double heavy beams spread at 
the front end to give a wide bearing where coupled to the 
frame. One of the beams is straight, while the other re- 
ceives only a side bend. The Avery Plow may be pulled 
through ordinary rocky ground without danger of break- 
age or bending of the beams, but if by any accident a beam 
should become sprung, it can be straightened by an 
ordinary blacksmith. 

wheel on an Avery Plow is also worthy of special note. 
It is located directly in front and just forward of the 
point of the plow. Each plow being entirely independent 
of the others and the gauge wheel being located in this 
position, it carries the point of the plow at a uniform 
depth at all times, which is one of the most important 
elements in perfect plowing. 

AVERY "SELF-LIFT" PLOWS were the first "Self- 
Lift" Engine Gang Plows built, and are fully covered by 
patents Nos. 819,223; 909,919; 933,858; 936,767. We have 
numerous other applications for patents pending, also 
Canadian patents and patents pending in Canada. The 
matter of infringement of patents and damages has al- 
ready been taken up and will be pushed vigorously against 
all infringers not licensed under our patents. Manufactur- 
ing licenses under our patents have been granted only to 
the following companies: Deere & Co., M. Rumely Co., 
Grand Detour Plow Co., Holt Mfg. Co., and Cockshutt 
Plow Co. in Canada. 


How the Avery "Power Lift -Self 
Drop" Device Works 

IN THE CONSTRUCTION of the "Power Lift-Self 
Drop" Device on the Avery Plow, a large simple clutch 
is used. When the cord is pulled, the clutch immedi- 
ately engages and the cord can be at once released. It is 
not necessary to hold it. All you have to do is to pull it 
an instant until the clutch is engaged. 

THE PLOW WHEEL is provided with grouters to pre- 
vent slipping, and the axle, to which the wheel is rigidly 
attached, carries a sprocket wheel from which power by 
means of a sprocket chain is conveyed to the clutch 

WHEN THE OPERATOR wishes to lift the plows, he 
simply pulls on the cord and this engages the clutch 
much after the fashion of the ordinary binder trip. 
This transmits the power to a diagonal shaft, extending 
the length of the plow frame, upon which is located an 
individual cam and lever for lifting each plow. This 
shaft turns one half revolution when the clutch is 
engaged. The cams are placed on the shaft at different 
angles. When the shaft turns, the cam for the forward 
plow operates to raise its plow first and each of the other 
plows are raised in turn when they reach the point where 
the first plow emerged from the ground. 

TO DROP THE PLOWS, the cord is again pulled and 
the clutch engaged, when the diagonal shaft turns the 
other half revolution, the first plow drops ahead of the 
rest and each plow in turn drops when it reaches the point 
where the first plow entered the ground. 

Accurate Adjustments 

THE ADJUSTMENTS on the Avery Plow are unusually 
accurate. The depth of plowing is regulated by a hand 
screw, as will be noted in the illustration, and can be 
changed easily and accurately. Much finer adjustments 
can be made than with a hand lever. In an advertisement 
one manufacturer states that the lever notches on their 
plow provide adjustments of ^-inch in depth, while with 
the screw thread adjustment on the Avery Plow you can 
adjust the depth to any fraction of an inch. 

A SET SCREW is also used on the plow standard to raise 
or lower the point of the plow to give more or less suck. 
An absolutely accurate adjustment can thus be easily 

IN ATTACHING THE PLOWS to the frame an 
eccentric coupling is employed for lining or winging the 
plows. After this very important adjustment has once 
been made, it is rarely ever necessary to adjust again 
during the life of the machine. 

Other Features on Avery "Self- 
Lift" Plows 

THE AVERY PLOW is mounted on supporting wheels 
of wide face and large diameter, all of which run on the 
unplowed ground. The construction of the Avery Plow 
is such that there is no side draft requiring a furrow 
wheel. The plow will follow the engine without slipping 
on the ground, and as all the wheels run on the unplowed 
ground, no special adjustments are necessary when open- 
ing up a new land. The width of the first furrow is gauged 
uniformly by a self-guide on the tractor. 

BY USING CROSS CHAINS for hitching the plow to the 
engine, the operator may commence turning at the end 
when the front wheels of the tractor are even with the end 
of the plowing and the plow will follow straight out, thus 
requiring only a short turning space at the end. 

THE GAUGE WHEEL itself is 13 inches in diameter 
and has a 4-inch face. It is made of two shell castings 
bolted together, and constructed in such a way that both 
faces of the wheel are completely enclosed and there is 
no rim to pick up and fill with mud or soft earth. It is 
carried on a hard maple bearing. This bearing receives 
a special treatment which thoroughly saturates it with 
special oil, and it will run in dust an indefinite period 
without lubrication. If it should ever wear, the box can 
be replaced as good as new at a very slight cost. 

AN ADJUSTABLE SCRAPER on the gauge wheel pre- 
vents accumulations on the face of the wheel and may be 
used or removed as desired, according to the condition 
and character of the ground. It is constructed in such a 
way that it does not interfere with the adjustment and 
working of the rolling coulter. 

ON THE 3, 4 AND 5 BOTTOM PLOWS we use a mal- 
leable standard; on the 6, 7, 8 and 10 bottom we use a 
heavy cast standard. The plow bottoms are made of 
heavy material and will stand the grief incident to being 
pulled by steam or gas tractors in tough or stony land. 
Any type of bottom will interchange with the beams on 
any size plows. 

THE PLOW FRAME, including the plow hitch, is made 
of steel plates, angle iron and channel bars riveted solidly 
together, thus making a construction that is very strong 
and proof against breakage. The castings that undergo 
the most severe strains are malleable, and the whole ma- 
chine, aside from being very strong, is so designed as to 
be light in weight. 

THE 6, 7, 8 AND 10 GANG PLOWS are mounted on four 
wheels. The 3, 4 and 5 gang plows have two main plow 
wheels and one of the single plow gauge wheels serves as 
a third bearing for the frame. The wheels are built with 
renewable boxes and are equipped with hard oil cups and 
so designed that they do not gather mud or trash in wet 
soil to cause them to clog. They are possessed of suffi- 
cient freedom to overcome any trouble of this sort.

Sanders Tractor Disc Plows 

THEY ARE LIGHT DRAFT. They will plow deep, 
taking the place of subsoil plows. They pulverize the 
soil equal to one harrowing. They will plow in sticky 
or hard ground. It hardly ever gets too dry to plow with a 
disc plow. They are simple in construction with nothing to 
get out of fix. They are strong and rigid. 

Framework of Sanders Plows 

THIS CONSISTS of a main frame, which is a solid steel bar 
made expressly for the purpose, to which is bolted a series 
of strong beams which carry the discs. All the principal 
parts of the plow are bolted direct to the main frame. One- 
inch bolts are used throughout the frame. 

Sanders Tractor Disc Plows 

CAN BE SET TO CUT either 6, 8 or 10-inch furrows. They 
are fitted with either 24, 26 or 28-inch discs. They have self 
guiding hitch, which does not change direction of plow when 
the front wheel is raised or lowered. They can be furnished 
with Power Lift, if desired. The wheels have combined 
Grease Cups and Dust-Proof Caps. They are set up to cut 
10-inch furrows unless otherwise ordered. They are fur- 
nished with 5-foot chain to attach direct to tractor. They 
can be easily changed to a different number of discs. Wheels 
either 3 or 6 inches wide can be furnished. 

Sanders Patent Discs 

THEY ARE MADE with a patent countersunk seat by 
pressing back the center of the disc into the shape of a 
countersunk head bolt, which gives a perfectly smooth sur- 
face over the entire face of the disc. One large bolt is used 
and that is at the center of the disc, where there is no motion.

Avery 5-10 H. P. Tractor 

IN ADDITION TO OUR FIVE larger size tractors 
from 8-16 to 40-80 H. P. previously illustrated and 
described, we also build a special small 5-10 H. P. size 
as shown here. It weighs only 2,250 pounds. 

THIS SMALL TRACTOR is designed for all around use 
on small farms and for doing the lighter work on large 
farms. The demand for this tractor is very large. 

THIS SMALL AVERY TRACTOR is intended to pro- 
duce a draw-bar pull equal to that of three 1,400-pound 
draft horses. It will accomplish as much work in the 
course of a day as four horses. Here are some of the 
things it will do: 


2 12-inch plows at a depth of 6 inches in ordinary 

stubble ground; 

a 16-inch plow under difficult conditions; 
an 8- foot disc harrow over plowed ground; 
a 3-section spike tooth harrow over plowed ground; 
a grain drill; 
a grain binder; 
a road drag; 
a loaded farm wagon; 
a potato digger; 
a manure spreader; 
and other loads ordinarily pulled by a 3-horse team. 

a small silo filler; 
a feed grinder; 
a pump; 

a fanning mill; 
a saw mill. 

WE BUILD THIS 5-10 H. P. TRACTOR with a special 
hitch so that you can use your old horse plow. Just at- 
tach your horse plow to the draw-bar and you have a 
complete tractor plow outfit. 

IF YOU HAVE HILLY GROUND and want to use both 
right and left hand plows to throw the furrows one way, 
you can attach both as shown in the illustration. When 
you do not want to plow back and forth, the left hand 
plow can be detached without interfering with the work of 
the right hand plow. 

YOU CAN RAISE AND LOWER the plows at the end of 
the furrows by a handy lever on the side of the tractor 
frame in easy reach of the operator while sitting on the 
seat. With the plow raised you can back up and turn 
around in a short space easier than you can with a team. 

THIS ATTACHMENT has many advantages over an 
engine gang plow. It is cheaper in first cost and lighter 
weight. It can also be easily detached when desiring to 
use the tractor for other kinds of general farm work.

Now You Can Also Cultivate Corn, Cotton, Potatoes 

and Other Crops Planted in Rows 

With Motor Power 

TRACTORS supply the demand for power to do plow- 
ing and other heavy farm work. But no sooner does 
a man get a tractor and find out the wonderful ad- 
vantages of using motor power for plowing, discing, drill- 
ing, harvesting, etc., than he begins to want to be able to 
also use the same kind of power for cultivating and other 
similar work. 

AFTER LONG CONSIDERATION and experimentation 
on this problem the Avery Company now offer their an- 
swer to the demand for motor power to do all kinds of 
farm work. For heavy work we build six sizes of Tractors 
a size to fit every size farm. For cultivating and other 
lighter work we now offer the Avery Motor Cultivator. 

TRACTORS HAVE PROVED that they are able to do 
away with the surplus horses formerly required the 
Avery Motor Cultivator now offers you the chance to do 
away with still more horses and use motor power prac- 
tically altogether, if not exclusively, for your farm work. 

MANY MEN HAVE HAD THE IDEA of a combination 
machine for doing all kinds of farm work. But the at- 
tempts to build such a machine seem only to have resulted 
in building something which is lacking on one or both 
sides. If it is built with the features necessary for heavy 
work it is not satisfactory for cultivating and such lighter 
work, if it is built for light work it lacks things which are 
required in a machine for heavy work. 

THE FIRST BIG ADVANTAGE of two independent 
machines a tractor for heavy work and a motor cultivator 
for light work over a combination machine is in the fact 
that while a two-row motor cultivator satisfies all the 
demands for light work, the same size machine, when used 
as a tractor, cannot supply all demands for heavy work. 
With the Avery independent machines you can get an 
Avery Two-Row Motor Cultivator to do your light work 
and can then get an Avery Tractor in whichever one of 
the six sizes is best suited to do your heavy farm work. 

THE SECOND BIG ADVANTAGE in having two inde- 
pendent machines a trnctor and a motor cultivator is in 
the fact that each machine is built with the design, 
strength, power, speed and all other features especially 
required for the class of work it is intended to perform. 

THE THIRD BIG ADVANTAGE in having two inde- 
pendent machines a tractor and a motor cultivator is in 
the fact that either machine can be attached to any tool 
you desire to pull by simply using a clevis without having 
to spend a big lot of work and time changing over 
attaching parts. 

MOTORIZE YOUR FARM the Avery way. Plainly the 
Avery plan offers you the most successful method of motor- 
izing your farm work an Avery tractor in the size which 
best fits the amount of heavy farm work you have to do and 
an Avery two-row motor cultivator for your light work. 

Double the Number of Acres You Cultivate 

with an Avery Motor Cultivator double or more as much 
as one man ordinarily handles with horses. 

THINK WHAT IT MEANS to start out for a day's 
cultivating with an Avery Motor Cultivator compared 
with the old horse way. 


curry them, harness them and clean out the stable. Then 
after eating breakfast, go out to the barn and get them 
out, water them and hitch up. All of this work to get 
started. Then it's unhitch, water, feed and hitch up at 
noon, and unhitch, water, unharness, feed and bed at night.

all this extra work before you can get started and after 
you get through? 

can do far differently. Getting the machine ready should 
not take you more than the time required to care for one 
horse. That's all it takes to get started. At noon and 
night, turn a switch. That's all it takes to get through. 
The time you save will enable you to take care of more 
profit making hogs, sheep or cattle.

How the Avery Motor Cultivator Is Built 


13. two-row machine. It will ordinarily 
cultivate about 16 to 18 acres per day. 

you a wide variation of speed so that you can 
plow as slow as necessary the first time over 
when your crop is small and at faster speeds 
when your crop is larger. 
THE CULTIVATOR is guided by a single 
front wheel which runs between the two rows. 
It is driven by two rear wheels which run 
outside the two rows. 

WHEN PLOWING along, the power of the 
motor is applied to both rear wheels by means 
of two clutches. Both rear wheels drive the 
cultivator and a compensating gear takes care 
of any variations in the direction of the rows. 
The front wheel guides the Cultivator rnd is 
operated by a hand steering wheel. 

WHEN THE END of the row is reached, the 
operator releases the steering wheel, which 
allows the front wheel to act as a caster. At 
the same time he takes hold of the two levers 
operating the drive wheel clutches, and by 
releasing one clutch and allowing the other to 
remain engaged, one drive wheel remains 
stationary while the other revolves around it 
until the Cultivator has turned around onto 
the next two rows. The other clutch is then 
also engaged and both wheels begin to travel 
forward. The operator releases the clutch 
levers and again guides the Cultivator with 
the steering wheel. 

THIS CULTIVATOR will turn around in its 
own length. It will turn either way depending 
upon which drive wheel the power is applied to. 

THE MOTOR used in this Cultivator is the 
same as used in our 5-10 H. P. Tractor. The 
Cultivator is gear driven no sprocket chain 
drive is used. The Cultivator itself is the 
regular Avery Two-row Cultivator which has 
been on the market for years.

of kinds of work you can do with 
an Avery Motor Cultivator. 

YOU CAN CULTIVATE corn, cotton, 
potatoes, or other such crops planted in 
rows. If you live in a listed corn ter- 
ritory you can get an Avery Motor Cul- 
tivator with a special lister attachment. 

YOU CAN ALSO PLANT corn, cotton 
and other similar crops with the same 
machine by getting a special planter 

THEN, BY REMOVING the gangs, 
you have a machine which you can use 
for various kinds of lighter traction 


work such as shown here hay raking, 
drilling, harrowing, road dragging, etc. 

YOU CAN ALSO DO lighter belt work 
feed grinding, pumping, sawing, silo 
filling, etc. 

THE AVERY Motor Cultivator is, in 
fact, an all around machine for lighter 
traction and belt work, in addition to 
being made with a design especially 
suitable for cultivating and planting.

Avery Threshers Are Backed by the Best Field Tests 

and the Strongest Guarantees 

Avery Threshers Have Made the 

Best Proven Grain Saving 


Threshers the average saving was 99 9/10 per cent 
practically perfect. Each of these tests was made on a 
different machine in a different locality and while being 
operated by the regular crew. Each of the tests was wit- 
nessed by a number of farmers who voluntarily signed 
statements showing the average percentage of saving. 

THESE TESTS PROVE that Avery Threshers are Won- 
derful Grain Savers. These tests are the best proven 
record of grain saving ever made by any make of 
Thresher. No other make of Thresher is backed up by 
such a record of grain saving field tests. 

Avery Threshers Are Also Backed 
Up by the Strongest Guarantees 

when you buy an Avery Thresher, in addition to the 
ordinary warranties against defects.

Warranty against breakages for life.) 

Special Warranty on Cleaning 

Thresher are guaranteed to clean the grain in perfect 
condition for the local market. 

Special Warranty on Feeders

IF ANY PURCHASER of Avery Machinery prefers the 
form of warranty adopted by any other manufacturer of 
this class of machinery, we will allow him the privilege, 
when placing the order, to substitute such other manu- 
facturer's form of warranty for ours, and such purchaser 
is hereby authorized before signing the order, to write 
across the face of the warranty in our order blank the 

"THIS ORDER IS GIVEN with the understanding that 
the warranty and all conditions of (insert name) Company 
are substituted in place of the warranty printed herein."

Avery Company stands squarely back of them and will 
make good on every point. 

AND THE REASON we can make these strong warran- 
ties much stronger than those given by any other manu-

Avery Threshers Have the Most Improved 
and Original Features 

THE FOLLOWING are some of the Original and Im- 
proved Features designed and introduced by the Avery 
Company which you get in an Avery "Yellow-Fellow." 

WE ORIGINATED and were the first to use the Big 
Cylinder Tooth called the Jumbo. This tooth has always 
been made from Razor Tool Steel and by an original pro- 
cess of forging and tempering, the wearing corner being 

WE ORIGINATED the double belting system from the 
cylinder to the crankshaft. Also the system of belting all 
the other important parts of the separator direct from the 
cylinder shaft, such as the fan, separating device and the 
beater, thereby driving them in proper speed relation to 
each other and giving wider belt surface from the cylinder 
shaft back. 

WE ORIGINATED the belt reel, which is of great con- 
venience in winding up, unwinding and taking care of the 

WE ORIGINATED the Wind Stacker without gears, 
with the fan located inside the frame work and driven 
with a straight open belt direct from the cylinder shaft, 
this belt being provided with a tightener so that the 
belt can be adjusted while the machine is in operation. 

WE ORIGINATED the band cutter and self-feeder with 
reciprocating knives and a governor located on the crank- 
shaft, whereby the crankshaft and all of the feeding parts, 
including the carrier, will stop when the speed of the 
cylinder falls below threshing speed. 

WE ORIGINATED a tailings elevator drive, with the 
lower sprocket located below the entrance of the tailings, 
which prevents clogging. We also originated the idea of 
leaving the upper end of the tailings elevator open, which 
permits the tailings to deliver on the ground in case the 
down spout is choked and thus prevents clogging the 
elevator in the head. 

WE WERE THE FIRST to introduce steel axles for 
carrying the weight of the separator. Previous to that 
time wood axles had been used, which resulted in numer- 
ous breakdowns, causing delays and loss of time and 

WE WERE THE FIRST to adopt an extension tongue 
of large size and so designed that it may be lengthened 
for horses and shortened when pulling the separator with 
an engine.

Avery Threshers Have the Most Improved 
and Original Features 

(Continued from previous page.) 

WE WERE THE FIRST to build a thresher with 
the grain pan, separating table, vibrating table and 
shoe all driven direct from one crankshaft, in such 
a way that the shaking parts counterbalance, so that the 
machine stands so steady that threshermen sit on top of 
them and write us testimonials to show that there is not 
enough vibration to make their hand shake at all. 

WE WERE THE FIRST to adopt a compressed paper 
cylinder drive pulley, which does away with all anxiety 
about the lagging coming loose in the middle of a hot day 
on a rush job. 

WE ORIGINATED the first really successful belt guide, 
and the only one today that carries the belt on the center 
of the pulley in a high wind when the engine is several 
feet out of line. 

WE WERE THE FIRST to adopt the marvelous separat- 
ing device known as the I. X. L., which hunts around in 
the straw for the last kernel and gets it, and we furnish it 
regularly with Avery Threshers, because we have proven 
its merits as a Grain Saving Device. 

WE ORIGINATED a pivoted cylinder box, which has a 
natural tendency to keep in line,.in striking comparison to 
the stationary type which had to be scraped by a thorough 
mechanic to ever get in line and then spends the rest of 
its time trying to get out of alignment. 

WE WERE THE FIRST to use a rubber feeder web on 
the Band Cutter and Self-Feeder, which runs noiselessly 
and without much wear and takes up all the loose grain 
and delivers it into the machine without wasting a large 
percentage of it. 

WE ORIGINATED a concave adjusting device by which 
the operator can raise or lower both the front and rear 
concave and adjust them for the different kinds of grain. 

WE ORIGINATED and were the first to use diagonal 
frame cross rods, located underneath the deck of the sep- 
arator which hold the frame work so rigid that it will run 
through a long number of years without twisting and caus- 
ing the shafting to bind in the boxes and quickly wear out. 

WE WERE THE FIRST to introduce and put on a sep- 
arator leveling jacks, attached to the separator, which are 
a great convenience for leveling and holding the front of 
the machine rigid while threshing. 

WE WERE THE FIRST to build a fan with bands to 
distribute the blast over the shoe and overcome the cross 
currents of air which had previously given threshermen 
so much trouble in properly cleaning the grain. 

WE WERE THE FIRST to encourage the manufacture 
of and to adopt the Closz & Howard Adjustable Sieve, 

which enables the thresherman to change his sieves for 
the different kinds of grain without stopping, adjustment 
being made by a small lever operated from outside the 

WE WERE THE FIRST manufacturers of threshing 
machinery that ever had the nerve to send out men during 
the threshing season in the various states where our ma- 
chines are in operation and make field tests for the benefit 
of our customers to show the actual amount of waste that 
was going into the straw stack, and then publish a correct 
report of these tests, after putting out a guarantee that 
these machines would save 99 52/100 per cent OR MORE 
of the grain. 

ALL OF THESE THINGS certainly show that the 
Avery "Yellow-Fellow" is without question the mcst 
original and improved machine built today and that's the 
kind of a machine that will make you money and you'll 
be proud to run. 

OTHER MACHINES have some of these features 
copied from the Avery or prompted by our introduction 
of them but no other machine offers you anywhere near 
all of them. You get them all only in an Avery. 

by hundreds to threshermen for use on other machines. 
But, after all, only a few of these can be gotten in this 
way as only a few can be attached to other machines.

ing Jack, I. X. L. Separating Device, and other Avery fea- 
tures to help cure the troubles he finds in some other 
make of separator, it would add just that much to the cost 
of his other machine, and after getting all these he would 
still not have the Avery Heavy Crankshaft, Steel Rod 
Pitmans, Double Belting System, Belt Winder, Steel Bot- 
tom No-Choke Elevator, Heavy Tongue, and all the other 
improved features found in the Avery "Yellow-Fellow." 

THE WAY TO GET ALL of these improved features is 
to buy an Avery "Yellow-Fellow." 

THIS LIST OF IMPROVEMENTS, designed and intro- 
duced by the Avery Company, will show you that the 
Avery Company is progressive that we keep pushing 
ahead that we are always designing and adopting im- 
proved features in our machines, and you will realize that 
in placing your order for an Avery Separator you get 
the most improved and up-to-date machine that can be 

detailed illustrations of these special features in an Avery 
Thresher on the following pages.

Look at This Strong Avery Separator Frame 

AN AVERY SEPARATOR FRAME is unusually strong 
and long lived. One of the most valuable features is 
the two diagonal steel brace rods just underneath the 
deck, which connect the upper ends of each of the 

two front posts of the main frame with the upper 
ends of the rear posts on the opposite side. These 
form a cross tie which prevents twisting and sagging 
of the frame. 





You Can Get the Grain Out of the Heads With 

an Avery Thresher 


can get the grain out of the heads with an Avery 

THE FIRST REASON is because it has a Long Concave 
and date Surface. In actual running inches an Avery 
Thresher has an open concave and steel concave grate 
surface of 18 inches; then at the rear of the cylinder a 
14-inch grate, and then under the beater a 20-inch grate, 
making 52 inches of grate surface, the whole width of the 
machine. This more than equals the grate surface of the 
so-called big cylinder machines. 

THE SECOND REASON is because the Concaves are 
Adjustable, Both Front and Rear. With the common 
arrangement for adjusting concaves you can only raise the 
front concave about half the length of the tooth, and can- 
not raise the rear concave at all, but with the Avery you 
can raise and lower both concaves and also adjust them 
the full length of the teeth. Furthermore, an Avery 
Jumbo Tooth is tapered and when you raise the concaves, 
the cylinder and concave teeth not only come closer to- 
gether endwise, but sidewise as well, so that you get a 
double adjustment. 

THE THIRD REASON is because an Avery "Yellow- 
Fellow" has an Adjustable Grate Behind the Cylinder. A 

good grate at the rear of the cylinder is a very important 
feature. Some manufacturers place a stationary grate at 
this point. A stationary grate may be all right in some 
conditions of the grain, but it can never be all right in all 
conditions of the grain. In an Avery Thresher the rear 
end of this grate is hung from two adjusting rods, allow- 
ing it to be raised or lowered. In wet grain you can let it 
down, and thus prevent wrapping; in dry grain you can 
raise it up closer to the cylinder. The fact that you can 
adjust this grate according to the condition of the grain, 
is a strong reason why you can get the grain out of the 
heads better with an Avery "Yellow-Fellow." 

THE FOURTH REASON is because of the Moving 
Grate Underneath the Beater. The 20-inch grate under- 
neath the beater is a part of the straw table. It moves 
back and forth with the table and the beater constantly 
pounds the grain through this moving grate. 

BECAUSE OF THIS Concave and Grate Construction, 
an Avery "Yellow-Fellow" when properly adjusted, will 
get the grain out of the heads and also separate out the 
largest possible percentage of the grain from the straw 
right at the cylinder. An Avery "Yellow-Fellow" has a 
better combination of devices to get the grain out of the 
heads than can be found in any other machine. 


Avery 36-Inch REGULAR Heavy Cylinder Filled With 

Jumbo Tool Steel Teeth 

AVERY CYLINDERS are built strong. The bars are 1% x % inches and are backed up by 
an inner bar l?/ 8 x f inches. The cylinder shaft is 2% inches in diameter and the cylinder 
has wide, heavy bands. They are also built extra heavy. The 36-inch size weighs 692 pounds, 
ready to run. That's why Avery Cylinders last longer and run smoother than others.

WE BEGAN MAKING Jumbo Tool Steel Teeth because 
we wanted to make it possible for our customers to get 
rid of so much trouble and expense with broken and worn 
out teeth. All the teeth used at that time were small; 
they were also untempered. They not only broke easily, 
but wore out very quickly, so that a full set of teeth had

to be replaced very often. A few years ago, in fact, even 
now with many machines, the sound of a broken tooth is a 
familiar one, and each time it is heard it means a shut 
down of from ten to fifteen minutes to put in a new tooth. 
A large amount must be charged up against many ma- 
chines because of the profits lost and the heavy expense 
of an idle crew while broken teeth are being replaced. 

THE FIRST THING WE DID was to design a large 
tooth. The Avery Company made the first large tooth 
ever used in a separator. That is why we call it by the 
name "Jumbo." 

THE NEXT THING was to get a metal that was strong 
enough so as not to be easily broken and that would wear 
long enough so that the teeth would not have to be often 

THE ONLY METAL we could find that in our opinion 
was good enough for the purpose, was genuine tool steel. 
We wanted breaking strength, and everyone knows the 
strength of tool steel. We wanted wearing strength, to- 
gether with a tempered wearing corner, and so we used 
tool steel, because machine steel will not take a temper. 
(Note this: That there is a big difference between tool 
steel and machine steel. Do not let anyone confuse you 
by telling you that they use steel teeth. Be sure you 
know whether they are machine steel or tool steel.) 

EVERY JUMBO TOOTH is guaranteed to be genuine 
tool steel. We hammer forge them from square Tool 
Steel bars and the wearing corner is tempered extra hard. 

HAVE YOU HAD EXPERIENCE with teeth that are 
easily broken and quickly worn out? Does your separator 
have that terrible toothache? Do you want a machine 
that never has this disease? If you want to be relieved 
of all tooth troubles, get an Avery "Yellow-Fellow" with 
its Jumbo Tool Steel Teeth. Pitchforks seldom even bend 
them, and even wrenches, spades and other similar things 
run through right along without breaking a single tooth 
or stopping the machine for a minute. Jumbo Teeth will 
bend double, are almost unbreakable, and will wear longer 
tb,an other makes. They are a big expense-saver for the 

WHEN YOU ARE BUYING a Thresher, remember that 
by getting an Avery "Yellow-Fellow" you will be free 
from tooth troubles.

two seasons which has given me perfect satisfaction, especially 
the cylinder teeth. They can't be beat. When I was operating

You Can Save the Grain With an Avery 


HE ILLUSTRATION above shows clearly why an 
Avery machine is built right to save the grain. 

NOTE IN THE FIRST PLACE the construction of 
the concaves and grates. The concaves are both ad- 
justable. The rear concave is not stationary as in many 
machines. The grate behind the cylinders in an Avery 
Thresher is also adjustable to suit the condition of the 
straw and not a solid stationary grate as used by others. 
There is also a moving steel grate underneath the beater. 
These three special features of construction in an Avery 
machine are such that a large percentage of the separation 
of the grain from the straw is done right at the cylinder. 

AFTER THE STRAW passes the beater it is thrown 
back on a lattice work section of the straw rack and is 
carried along by the motion of the rack. 

IT THEN REACHES the famous I. X. L. Grain Saving 
Separating Device which is furnished with every Avery 
Thresher. Underneath this separating device is a set of 
toothed steel plates. 

THERE NEVER HAS BEEN a separating device of any 
description made that will do the work that this I. X. L. 
does in tearing up the bunches and spreading the straw out 
into a thin layer so that the grain is free to drop through. 

THIS I. X. L. SEPARATING DEVICE consists of six 
bars on which are located a number of fingers. The bars 
are driven by gears connected with the main shaft as 
shown in the end view illustration here. The movement 

of these bars is such that the fingers remain at all times in 
a perpendicular position. Six sets of fingers dip into the 
straw at each revolution of the main shaft, which runs 125 
revolutions per minute, thus 750 times per minute one set 
of fingers dips into the straw and loosens it up. 

each set of fingers at each turn. They draw the straw out 
into a thin layer, spread it apart, move it rapidly and tear 
up all bunches of straw, whether wet or dry, and let the 
grain drop through. The layer of straw is very thin at 
this point and the kernels that are left in it cannot help 
but drop out. This separating device runs steadily and 
quietly and the guards and its own speed easily keep it 

BEHIND THE I. X. L. are placed toothed fish backs on 
the straw rack slanting upwards. This rack has a strong 
motion upward and backward and as the straw moves 
along over these toothed fish backs it is well shaken and 
every chance is given any few remaining kernels to drop 
through out of the straw. 

THIS COMBINATION of Separating Parts Adjustable 
Concaves, Adjustable Grates, I. X. L. Separating Device 
and Toothed Rack makes an Avery "Yellow-Fellow" a 
wonderful Grain Saver, as is proven conclusively by the 
Records of Field Tests and our Strong Grain Saving 
Guarantee given on the opposite page. 

YOU CAN SAVE THE GRAIN with an Avery "Yellow 
Fellow-Grain Saver" Thresher. 


Avery Threshers are the Cham- 
pion Grain Savers 

THERE IS JUST ONE WAY to absolutely prove what a 
Thresher will do in saving grain, and that is to make a field test. 
For several years we made field tests on Avery "Yellow- 
Fellows" to prove what they would do. Twenty-seven tests 
were made at different times. Each of these tests was made on a 
different machine, in a different locality, in eight different states and 
while being operated by the regular crews. Each of the tests was 
witnessed by a number of farmers who voluntarily signed statements 
showing the average percentage of saving. 

THESE TESTS PROVE that Avery Threshers are Wonderful Grain 
Savers. The average saving in the 27 tests was 99 9/10 per cent 
practically perfect. 

JUST THINK OF IT! Twenty-seven actual field tests, threshing 
on canvas, and an average saving of 99 9/10 per cent. This is the 
best proven record of grain saving ever made by any make of 
Thresher. No other make of Thresher is backed up by such a record 
of grain saving as this. It is so good that we have added the words 
"Grain Saver" to the name of the Avery Separator and now call it the 
"Yellow Fellow-Grain Saver." 

AND BESIDES BEING BACKED UP by these tests when you 
buy an Avery "Yellow Fellow-Grain Saver" you also get the strongest 
definite guarantee on grain saving ever given with any make of 
machine. This guarantee is printed right in the order blank. 

"AVERY SEPARATING DEVICES are guaranteed to shake out 
99 52/100 per cent OR MORE of the loose grain that is in the straw, 
the grain to be dry and in fit condition to thresh. When desired we 
will submit the machine to test." 

THIS IS THE STRONGEST definite grain saving warranty ever 
given. It is absolutely plain and straightforward. It means exactly 
what it says and there are no impossible conditions connected with it 
in any way, shape or form. We guarantee a saving of 99 52/100 per 
cent OR MORE and the "or more" means anywhere up to 99 99/100 
per cent, for this record has been made by "Yellow-Fellows" in 
field tests. 

THESE TESTS and this strong guarantee are positive proof that 
you get a genuine Grain Saver when you buy an Avery Thresher.

You Can Clean the Grain in Fine Shape With an 

Avery "Yellow-Fellow" 

why an Avery Thresher does extra fine cleaning of 
the grain : 

FIRST The steel bands in the fan give an even distribu- 
tion of the blast over the entire surface of the sieves and 
prevent the usual cross-blast. Every experienced sep- 
arator man will understand the advantage of this. 

SECOND The fan is placed farther from the shoe, and 
because of this greater distance the blast has time to 
spread out more uniformly over the sieves than in other 

THIRD The fan-housing is built up higher between the 
fan and the sieves. 

WITH THIS CONSTRUCTION, the blast enters the 
shoe through a narrow opening and is strongest just as it 
strikes the sieves (right where they are loaded the 
heaviest) and as the blast passes back it gets softer and 
softer and so does not blow the grain over at the back end, 
where the sieves are loaded the lightest. With other 
separators, where the housing is not built up behind the 
fan, the blast enters the shoe through a large opening and 
is choked down to a point at the back end, so that you get 
the lightest blast at the front end where the sieves are 
loaded the heaviest, and the strongest blast at the back 
end, where the sieves are loaded the lightest (it is just 
like forcing a 4-inch stream of water through a 1-inch 
nozzle). Then when you close the wind boards sufficiently 

to keep the grain from blowing over, the blast is not 
strong enough on the front end where the sieves are 
loaded heavy, to do perfect cleaning of the grain. Look 
into other separators and see the short distance between 
the fan and the shoe and the wide opening where the blast 
enters the shoe, and you will understand why many 
machines do poor cleaning.

tors All Say That Avery

All Avery Threshers Have Two 
No-Choke Chaffers 

ONE IS ATTACHED to the rear end of the grain pan 
and extends back over the shoe 30 inches. The other is in 
the shoe. These chaffers are so constructed that all ma- 
terial passing over them is easily and quickly separated. 
The corrugations and the turned-up edges of metal be- 
tween them carry all the material very loosely, enabling 
the wind-blast, which is turned in an upward direction by 

Closz & Howard Adjustable 

in place of the regular Sieves, when desired, and without 
extra charge. 

AFTER INVESTIGATING and experimenting with dif- 
ferent makes of adjustable sieves we are able to recom- 
mend this one when an adjustable sieve is wanted, and feel 
sure that it will prove more satisfactory than any other 
adjustable sieve on the market. It is built in a very 
strong and substantial manner and is adjustable from out- 
side the separator. Made with our special malleable sieve 
corners. We charge extra for these sieves, but will allow 
for regular sieves not taken. 


Strength and Convenience 

RE TWO THINGS we have always worked for in designing an Avery 
Thresher. And we have given unusual attention to the smaller 
features which are often passed by. 

READ HERE ABOUT some of the original and improved smaller fea- 
tures in an Avery Separator and see how they are designed to give you a 
stronger and easier handled machine. 

All Avery Threshers Have Iron 
Crank Shaft Posts 

WHEN THE CRANKSHAFT BOXINGS are bolted to wood posts in the 
separator frame, there is always a possibility of the post springing and 
the shaft bending out of line. The Avery Iron Crank Shaft Posts over- 
come all this and hold the crankshaft firmly in position, without danger of 
springing under heavy strains. 

The Avery Main Thresher Crankshaft is 2 Inches in Diameter 

OUR SEPARATOR CRANKSHAFT is 2 inches in diameter, or from % to % of an inch 
larger than the ordinary separator crankshaft, and on that account much stronger. It is 
made of the best steel and is neatly bent and turned. The size of the Avery shaft makes it 
extra strong, and almost wholly does away with all possibility of its being sprung out of 
line in any manner. 

Avery Vibrating Tailer Pitmans Are Made from Steel Pipe 

THEY ARE LIGHT IN WEIGHT and much stronger and neater than wood pitmans. 
They have maple boxings at each end with hard oilers attached and take-up provisions for 
wear and lost motion. This pitman leads from the separator crankshaft to the rear rock 
shaft, and drives the rear straw rack and the return grain pan. 

Avery Shoe Pitmans Are Made from Double Steel Pipes 

THEY HAVE HEAVY MAPLE BOXES at each end. Bolts extend through the pipes 
from one end to the other, thus holding the boxes in a substantial manner and providing a 
simple method for taking up wear and lost motion at either end. This pitman is operated 
by the main crankshaft, and one is used on each side of the separator to drive the shoe. 


This is the Famous Avery Double 
Cone Pulley Belt Guide 

OUR BELT GUIDE is constructed with tapering 
cone pulleys set at such an angle that the belt sur- 
face is flat and runs at the same speed at all times. 
Notice that the flanges are a part of the pulleys, and as the 
belt is driven by the wind it is held by the flanges, which 
are running just as fast as the belt is, and so protect the 
edges of the belt instead of wearing them off, as other 
makes of belt guides do, where the edges of the belt are 
constantly rubbing against pulleys that only run when the 
belt is forced against them. When the belt is blown to 
the side, the guide quickly runs the belt back to the center 
of the pulley. It also holds the under part of the belt up 
closer around the cylinder pulley, giving you more lap, 
preventing slipping and adding that much more to your 
power. This is, without question, the best belt guide 
made. It must be a fine thing, for we sell hundreds of 
them every year to threshermen to be used on other makes 
of machines. 

All Avery Threshers are Equipped 

with Compressed Paper 

Cylinder Pulleys 

ing advantages: 

IT GRIPS THE BELT much better than wood, leather 
or iron; there is no covering to quickly wear out; it saves 
time and trouble replacing worn out laggings ; it lasts 
longer than others; the main belt can be run slacker, 
which increases the life of the belt. 

All Avery Threshers, Size 32x54 

and Up, are Double Belted from 

the Cylinder Shaft to 

the Crankshaft 

WE ALSO USE WIDE BELTS, the narrowest belt being 
4 inches wide. On single, narrow belted machines the 
belts have to be drawn up to such a tension that they wear 
out quickly and also draw the shafting tight so that the 
machine runs harder. Avery Separators, from 32 x 54 up, 
are driven with 22 inches of belting surface, besides the 
main drive belt; the smaller sizes with 18 inches. Easy 
on belts and the separator always runs smooth. Another 
valuable point in an Avery is that all the principal belts 
are equipped with belt tighteners. 

This Improved Belt Winder is 

Furnished With All Avery 


THE BELT IS CARRIED underneath the feeder it is 
out of the way when pulling between the stacks. It is 
also protected from injury by the weather. With this 
Belt Winder you can very easily wind up or unwind the 
drive belt. There is no sagging of the separator fram*, 
as often happens when the heavy drive belt hangs on one 
corner of the frame. 


An Avery Tailings Elevator Has 
Four Original Fine Features 

FIRST It has a steel bottom which doesn't cut out in 
ridges or wear the face of the blocks uneven, as do the 
wooden bottom elevators. 

SECOND The drive sprocket is located below the en- 
trance of the tailings, which keeps the sprocket clear and 
prevents clogging. 

THIRD The sprocket chain drive also does away with 
slipping, common with belt-driven separators. 

FOURTH The upper end of the tailings elevator is 
open, which permits the tailings to be delivered on the 
ground in case the down spout becomes choked and thus 
prevents clogging the elevator in the head. 

Avery Threshers Have Remov- 
able Iron Beater Castings 

IF FOR ANY REASON you wish to remove the beater 
from an Avery Separator, all that you have to do is unbolt 
the iron casings on either side, after which the beater can 
be easily lifted out.

THE TONGUE CENTER on all except the "Yellow- 
Kid" sizes measures 2% x 6 inches, and each of the two 
sidebars 2^4 x 4 inches. This is a slip-tongue and the 
tongue center can be extended far enough so that you can 
pull the separator with horses or so that you can couple 
your engine on and make a move without having to fold 
the feeder back over the deck.

All Avery Threshers Have Steel Axles 

THEY ARE MADE FROM STEEL BARS, bridge trussed and bolted together. 
Each axle has a carrying capacity of several times the weight that rests upon it. 
There is no comparison between them and the old style, wooden axles, still used by 
some manufacturers, which rot out and break down and cause so much expense and 
loss of time.

This Bartholomew Automatic Band Cutter and 
Self-Feeder Feeds Even, Fast and Clean 

AERY FEEDERS do even feeding without slugging. 
They are built to feed the bundles in the same way 
as is done by hand. The knife bars dip into the 
bundles and thoroughly loosen them up. The motion of 
these arms also feeds the bundles in from off the top, 
while the steel plates and pins in the grain pan hold back 
on the lower part of the bundles. This is exactly the way 
that hand feeding is done. That's why you get even 
feeding without slugging with an Avery Feeder. 

them say that the capacity of Avery Feeders has never 
been reached. We do not use any delicate feeding devices, 
such as are often used, which greatly reduce the capacity 
of the feeding and wear out quickly. 

equipped with solid rubber feeder carriers, which carry 
the loose grain and chaff into the machine instead of wast- 
ing the grain and leaving a lot of litter to clean up. They 
are also much more durable and do not break and cause 
the trouble which the chain carriers do. 

YOU ALSO GET the following strong warranty with 
this feeder: 

FEEDER is guaranteed to feed all kinds and conditions 

of loose, headed or bound grain without slugging the 
cylinder, and faster and more evenly than feeding can be 
done by hand. 

YOU GET THIS WARRANTY printed right in the 
order blank. 

YOU CAN SEE from the construction of an Avery 
Feeder that it is built to do even, fast work and to last a 
long time. If it didn't do it we couldn't give this strong 
warranty that goes with every order. Read the letters 
from users which we publish telling about the work of the 
Avery Feeder and ask anybody who owns one and you will 
find that Avery Feeders do all we claim for them. 

This is One of the Strong Avery Feeder Knife Arms. A Hard Oiler 
is Furnished for the Journal. The Knife Bars are Adjustable to

The Crankshafts on Our 36 and 42-inch Feeders are Made from 1 34-inch Open Hearth Steel. Those on the Smaller Sizes from 1^2-inch. 
All the Bearings are Accurately Machined. They are Heavier than Many Others and Less Liable to Spring or Break. 


The Avery Feeder Governor is 
the Best Governor Made 

the carrier and hence allow the feeding parts to 
keep on pulling grain into the cylinder, even when 
the speed is low, but the Avery Governor cuts off and 
stops the feeding parts, as well as the carrier. Further- 
more, on other machines the feeding parts start with the 
cylinder, and thus often slug or choke it at the start, but 
with an Avery Feeder no part of the feeder will go to 
work until the cylinder has reached threshing speed, then 
the whole feeder starts into operation and takes care of 
the grain which the pitchers have pitched into it while the 
machine was stopping. 

THIS GOVERNOR IS, furthermore, very sensitive in 
stopping and starting, and also has a wide range of adjust- 
ment, so that it will give you perfect control in all kinds 
of grain, whether threshing a small or large number of 
bushels per minute. Another feature of importance is 
that our governor is strong enough to control a feeder 
extension also. 

The large pulley is loose on the shaft and is driven by the 
feeder drive belt. Attached to it are three clutch arms, 
on the ends of which are wooden, clutch blocks. The 
smaller inside pulley is keyed to the crankshaft. 

pulley revolves until the speed becomes fast enough to 
overcome the tension of the springs which hold the ends 
of the clutch arms, the clutch blocks then engage the in- 
side pulley and the feeding parts and carrier start in mo- 
tion. When the speed gets too low the clutch blocks 
release from the small pulley and the feeding parts and 
carrier stop. The weights on the clutch arms give a wide 
range of adjustment for different conditions. 

THE GOVERNOR is one of the most important parts of 
a feeder, and the Avery leads them all. 

This Shows the Steel Division 

Plates and Retarding Pins on 

the Avery Feeder Pan 

STEEL PLATES are bolted to the feeder pan. These 
plates straighten any bundles that have started in cross- 
wise. No bundles can pass through to the cylinder with- 
out being thoroughly split up by these plates and the knife 
bars. Notice also the steel retarding pins in the bottom 
of the feeder pan which hold back on the bottoms of the 
bundles and cause them to be fed in from off the top. 

Avery 6 and 8-Foot Feeder 

NO LEGS ARE REQUIRED to hold up the end of either 
our 6 or 8-foot carriers. There is nothing for the wagons 
to run against and cause the carrier to fall ; neither does 
the carrier have to be folded when a move is to be made. 

OUR FEEDER CARRIERS fold easily over the top and 
out of the way. The springs are attached just right to do 
almost all the work.

that with our Extensible Tongue only the first fold 
need be made to couple the engine on and make a 
move. The second or top fold is excellent for stor- 
ing the thresher, the carrier being entirely out of 
the way. 

Avery 18 -Foot Mounted 
Feeder Extension 

REMEMBER THAT, unlike other makes, the 
Avery Feeder Governor is strong enough to control 
this Extension also, and that the carrier on the 
Feeder Extension does not keep running and piling 
up the grain after the feeder carrier has stopped. 
This is an exclusive Avery feature.

You Pay the Same Price and Get a Whole Lot More for 
Your Money When You Buy a J. B.'s Wind Stacker 

WE INVITE COMPARISON between our Wind Stacker and all other makes. 
Just notice the cast iron elbow, special hood, heavy fan, steel fan housing 
and other parts, and compare these with others. Our Wind Stacker is made 
from heavier and better materials and costs more to build than any other 
stacker on the market. 

OUR STACKER FAN is driven with a straight open belt direct from the 
cylinder shaft. There is no gearing to rattle or break, and no power lost by 
the belt having to travel around the rear corner of the separator frame. 
^ The belt is also equipped with a good tightener by which the tension can 

be adjusted as desired and without stopping the machine. 

THE SEPARATOR MAN can stand on the ground and easily raise 
or lower the pipe by means of the ratchet lever; can extend it or 
shorten it with the cable and the crank lever, and can adjust the 
hood in the manner desired. No need to climb up on top of 
the separator. 

WHEN YOU GET an Avery 
Wind Stacker you also get the fol- 
lowing Special Stacker Warranty: 

AVERY J. B.'S Wind Stackers are 
warranted to handle dry or wet 
straw in any condition or quantity 
without choking, and to be built 
with tank steel fan housings and 
boiler plate wings. 

THE AVERY J. B.'S Farmer's 
Friend Wind Stacker is made of 
the Best Materials, has the Best 
Design, and is the Strongest Guar- 
anteed Stacker Built. 

THE STACKER PIPE is supported by a heavy steel 
brace attached to the rear lower corner of the wind 
stacker frame. No tackle or blocks needed to carry 
the pipe, and our manner of supporting it also 
prevents any strain coming on the reversing gear 
to wear it out. 


Stacker Fan 
is the 
and Heaviest 
Fan Used in 
Any Wind 

HAS %-INCH STEEL boiler plate wings 
much stronger than the sheet iron style. Pitch- 
fork handles don't bend or break them, and they 
will take care of more straw and blow it to a 

greater distance than will other wind stacker 
fans. Total weight of fan is 150 Ibs. It runs 
smoothly. The fan head alone weighs more 
than most other complete fans. 


This Wind Stacker 
Hood Spreads the Straw 
Out and Builds a Fine Stack 

r-pHRESHERMEN TELL US that our wind stacker 

hood is a fine improvement. With it you can build a 

1 better stack, and if you use a man in the straw he 

will have much easier work than with the old style 

round stacker hood. 

THIS HOOD is so hinged that it maintains a perfect 
curve, no matter in what position it is placed, thus causing 
the straw to always pass out in a steady, unchecked stream. 
The outer end of the hood has a broad, flat face, with 
square sides, which spread the stream of straw out into a 
wide, thin sheet, depositing it over a large area on the 
stack and without too great a force. These thin layers of 
straw lap back and forth upon one another and bind the 
stack into one compact mass, while with the round hoods 
large bunches of straw are delivered in one place, holes 
are bored in the stack, large chunks rolled off and the 
stack built up piece by piece. With this hood you can 
place the straw anywhere you wish, build up the stack 
more uniformly, bind it closer together, top it out in finer 
shape and make a better built and more waterproof stack. 

Reversing Gear 

INSTEAD OF ATTACHING our Reversing Gear, piece 
by piece, to the wooden wind stacker frame, the gearing is 
mounted in an independent iron frame, and this iron frame 
is then bolted to the wind stacker frame, hence the gears 
cannot get out of line and run hard or wear out un- 


Our Wind Stacker Fan 

Made of Heavy Sheet Steel 
and Boiler Riveted 

JUST COMPARE IT with one of 
those fan housings with wooden heads 

and galvanized iron nailed on for a 

casing, or with any other kind of 
a fan housing. It is the Strongest 
the Most Durable one of all. 

THE BOTTOM of our fan hous- 
ing is also widened out and when 
the straw reaches the mouth of 
the housing the force of the 
blast made by the fan carries most of the straw 
up the stacker pipe without the fan wings having 
to touch it at all. This largely increases the 
capacity and helps to prevent clogging and cut- 
ting up the straw. Threshermen ^^^ 
say that the only way to clog an 
Avery Wind Stacker, with 
this fan housing, is to 
throw off the wind 
stacker belt.

Our Wind Stacker Elbow 
Is Cast Iron 

JUST COMPARE IT with the ordinary tin or galvanized 
iron styles. The passage of the straw doesn't wear holes 
in this cast iron elbow like it does in the tin or galvanized 


Low Down Barn Style Thresher 

FOR TERRITORY in which a considerable portion of 
the threshing is done in barns, our low down barn 
style machine, as shown above, is just the thing. The 
deck of the Thresher is cut down at the rear to permit 
locating the turntable 7 inches lower than the regular 
style. The chute used on this machine differs from that 
sent out with regular wind stackers ; the elbow is shorter, 
and both the lifting and telescoping devices are arranged 
to operate from the deck. When the stacker chute is 

folded on top of the Thresher the highest point of the 
elbow is only 10 inches higher than the upper end of 
the return elevator. The reduction in height of our 
machine is not made by cutting down the size of the truck 

THIS ILLUSTRATION likewise shows the Russell type 
of Wind Stacker, which we also build and which operates 
from the deck. 

Sattley Attached Swinging Stacker 

AS AN ATTACHED STACKER there is certainly noth- 
ing made better than this one is in its construction or in 
the work which it will do. It can be furnished for any 
size thresher. Stackers for 28 x 46-inch and larger 

machines have automatic oscillating turntables. Those 
for the "Yellow-Kid" sizes do not have the automatic 
oscillating attachment, but can be swung around by 


A very 15 -Barrel Steel Water Tank 

Mounted on Our Regular 

Steel Tank Trucks 

WE SHOW ABOVE our Steel Water Tank mounted 
on our regular Steel Water Tank Trucks. The 
front wheels are 33 inches and rear wheels are 39 
inches high, with 4-inch tires. The tank is made of No. 12 
tank steel and is built round, 36 inches in diameter, and 
108 inches long over all. A good spring seat is furnished 
for the driver. Eight-inch flaring side-boards are ar- 
ranged on top for carrying anything that is desired. On 
one side, near the center, is a hook for carrying a lifting 
jack, and on the opposite side are hooks for carrying the 
flue cleaner and scraper for the engine. 

A STEEL SPLASH-BOARD is riveted in the center of 
the tank, which prevents the water from running rapidly 
from one end to the other while being hauled up or down 
hill or in bad places. At the rear is provided a step, where 
the operator may stand when pumping, or he may stand on 
top, as may be desired. An opening is made in the top of 
the tank, close to the front end, in which is fitted a piece 
of 2i/2-inch boiler flue, extending downward 10 inches; 
this leaves sufficient opening through which to insert a 

Avery 1 5-Barrel Steel Water Tank 

With Wood Saddles for Mounting 

on an Ordinary Wagon Gear 

THE AVERY STEEL TANK can be furnished mount- 
ed on our regular Steel Tank Trucks, or with bolsters for 
mounting on an ordinary wagon gear. 

1-inch hard rubber suction hose; thus water may be taken 
from the tank and supplied to the engine while moving. 
On account of the flue extending downward, water will 
not splash out at the opening. A manhole, sufficiently 
large to admit an ordinary pail, is located near the tank 
pump. The tongue is made so that by taking out one piece 
it can be coupled very short when it is desired to haul the 
tank behind the engine. Being built in cylindrical form, 
the front wheels turn sufficiently to allow a very short 
turn to be made without cramping. The tank is finished 
and painted in nice style and is complete in every detail. 
It is light, strong and durable. 

IN COMPARISON with the old style wooden water 
tanks which require soaking up, which allow a great deal 
of water to leak out, are heavy to haul and soon rot out, 
the Avery steel water tank overcomes all these disadvant- 
ages, since it is always ready for use, has no leaks what- 
ever, and will last for a much longer time. While the first 
cost may be a little more, the Avery Steel Tank is unques- 
tionably the more economical in the end.

General Description of Avery Single Cylinder 
Straight Flue Steam Engines 

These Engines have many of the special features designed by the Avery Company and used 

for years on our other steam engines. They also have a number of new 

features which have appealed strongly to engine users 

Avery Boilers are Reinforced for 
Carrying High Pressures 

AERY BOILERS are built for carrying high pres- 
sures. They are reinforced under each bracket and 
have long stay rods reaching from the front to the 
rear head. 

THE BOILERS have long flues and large fire boxes. 
There is a 1-inch space between the flues at the rear end 
which insures perfect circulation and a strong flue sheet. 
The flues are arranged perpendicularly so that there is a 
J/z-inch vertical space between each row, making it pos- 
sible for the sediment to easily drop through. Will burn 
straw, coal or wood. 

THE GENERAL EQUIPMENT of the boilers on these 
engines is unusually fine. They have Brick Arches and 
Rocker Grates. The original Avery Automatic Fire Door 
is furnished regularly. This is a fine feature. It is so 
arranged that it can be operated by the engineer either 
when standing on the platform or on the ground. The 
door is opened by pressing one foot on the lever, leaving 
both hands free to handle the shovel. The door closes 
automatically when the foot pressure is released. 

gines is the Heater. This is so constructed that it is 
wonderfully efficient. It will heat the water to the boil- 
ing point before it enters the boiler, making these engines 
unusually easy to steam and economical. 

The Avery Curved Block Reverse 

Gear Gives Equal Lead 

and Cut Off 

the expansion of your steam. To get expansion it is 
necessary to hook up your valve gear and close the steam 
ports earlier. One of the hardest problems which de- 
signers have had to solve has been to produce a simple 
valve gear that would positively give an equal lead and 

cut off at all points of the reverse lever quadrant when 
hooked up as well as when wide open and whether running 
forward or backward. 

THE LINK MOTION is too complicated and has too 
many joints and pins which quickly wear and become 
loose and throw your valve off. 

THIS AVERY REVERSE GEAR is the only valve gear 
that is positive in action and at the same time is simple in 
construction. It has few wearing points. These all have 
abundant take-up provisions. It has only one eccentric. 

IT IS EQUIPPED with our own design Curved Slide 
Block and will give an equal lead and cut off at all points 
with the reverse thrown clear over or hooked up, and 
whether the engine is running in one direction or the other. 
The curve in the block also makes it extremely quick 
opening, which allows the steam to hit the piston head a 
regular sledge hammer blow, giving you greater power on 
the start of the stroke and allowing you to hook up the 
valve and let the piston travel the balance of the way on 
expansion which produces the greatest economy. 

most important features which makes an Avery Engine 
economical and powerful. 

The Avery Friction Clutch 
is a Dandy 

OUR FRICTION CLUTCH has long, heavy shoes, which 
cover about one-half the circle of the flywheel. They 
hold fast when the clutch is thrown in. The shoes push 
straight out against the rim and thus bring no end thrust 
on the main shaft to quickly wear the engine out of line, 
as in the case of those which engage from the side on a 
beveled surface. When the clutch is thrown out they are 
drawn well back from the wheel. 

THIS CLUTCH NEVER BINDS, and yet the action is 
so delicate that the engine can be moved an inch at a time. 
You can depend upon this Clutch holding or letting go 
when you want it to. 


All Avery Engines Are Regularly 

Equipped With Automatic 

Self -Coupling 

Draw Bars 

AL YOU HAVE TO DO is to back the engine up and 
guide the end of the tongue into it when you want 
to couple the separator to the engine. To uncouple, 
pull the chain and you are ready to go. By removing the 
pins the bar can be swung to either side for convenience 
in coupling up. 

Special Avery Frame Relieves 
Boiler of Strains 

IN BUILDING THIS ENGINE our designers worked 
with the idea in mind of reducing the number of bolts in 
the boiler to the minimum. Following out this idea, they 
designed a special angle and flat bar steel frame to which 
the axle and countershaft brackets are attached instead 
of directly to the boiler. The boiler is then bolted to this 
steel frame with as few bolts as possible. It is practically 
carried in a saddle between the two angle bars of the 
frame. One of the worst sources of trouble on ordinary 
engines is where the countershaft boxes are bolted to the 
corners of the boiler. All these troubles are eliminated 
on the Avery Engine by bolting the countershaft boxing 
to the angle bar frame and not to the boiler. The counter- 
shaft box is a full length solid boxing. It has long bab- 
bitted bearings in each end. The center is arranged as an 
oil well and a grease cup is also placed on each end. 

Avery Brackets Have Many 
Improved Features 

ALL THE BRACKETS on these engines are put on with 
stud bolts. No cap screws are used. They are laid out 
in such a way that any bracket may be removed without 
removing a single bolt. All you have to do is to take off 
the nuts. You do not have to disturb the tight steam 
joint made between the stud bolt and the boiler when the 
bolt is first put in at the factory. 

site page that the pillow block and intermediate gear 
bracket are all one casting, thus insuring the absolutely 
correct mesh of the crankshaft pinion and intermediate 

gear. We also use on these engines a special tie rod be- 
tween this bracket and the frame angle bar, which like- 
wise insures a positively correct mesh between the 
intermediate and compensating gears. 

All Avery Gears are Steel 
and Semi-Steel 

the rest of the gears are semi-steel. We have found that 
for the larger gears semi-steel is superior to all-steel, as 
it wears much longer, and by using a high grade quality of 
material we are able to produce a semi-steel gear that for 
traction engine use is almost as unbreakable as all-steel. 
The best proof of the quality of these is that we have had 
but comparatively little call for gears for repairs since we 
have used this combination. Another feature of the Avery 
gears is that they are all made from cut metal patterns. 
No wood patterns are used, as is done by some companies. 
This is why Avery gears are perfectly round and true and 
always absolute duplicates. 

General Fittings

The A very Policy A Good Machine and a Square Deal 

Avery Design 

build what you want. We investigate your needs care- 
fully and work out many original improvements, but to 
a large degree we are guided by the suggestions made 
by the large number of owners of Avery machines. 
THAT'S WHY THE AVERY line of machinery leads in 
Originality and Improved Construction. The reason is, 
because we have recognized the fact that our job is to 
build the kind of machines you want and we have been 
open to suggestions from every source and these sugges- 
tions have had the consideration of practical men who 
know your needs. Doesn't this appeal to you as being the 
way in which a machine ought to be designed? 

Avery Materials 

THE STANDING ORDER originally given to every 
workman by our first president, Mr. R. H. Avery, and 
which has been continued ever since, and always will be 
continued, is not to put into a machine a piece of material 
that he wouldn't put in if he were building the machine 
for his own use. 

machinery you buy, isn't it? Well, that's why we use that 
kind of materials because we believe you want it. 

Avery Tests 

EVERY YEAR you find Avery machinery entered in 
contests or demonstrations. The "Bull Dog" is always 
there. We are willing to show you what we've got com- 
pared with others. 

WHEN THERE'S A GOOD REASON why a special test 
is required, we will make it. You can have any fair test 
you want. We're here to build machines that meet your 
needs. ' J?.; ^ 

THERE'S ANOTHER THING-Jrd you eve'r notice 
what owners of Avery machines say- about. them? 

WE SAY, "Ask any owner of an Aver^i D6 it. See 
what they say. '. - .4 

Avery Guarantee's 

WE DON'T CARE how strong a guarantee a man wants 
just so it's fair and he is willing to give us a square 
deal we will give it to him. Ave'ry Machinery is backed 
up by the strongest guarantees ever given by any company 
selling machinery. 

BUT WE DO EVEN MORE than we guarantee. These 
guarantees put the Avery Company squarely behind every 
Avery machine. It isn't just your order we want we 
want your friendship and good will, and also your backing 
and recommendation to help sell the next man. We take 
care of your needs and help you to keep your machine 
running steady and giving you the best service. It's the 
Avery policy to take care of its customers. 

WE ARE PROUD of Avery machines. We are glad to 
back up the kind of machines we build. That's what you 
want isn't it a Company to stand behind the machines 
they sell you? Well, that's just what we do. 

Avery Prices 

that you can buy articles of the same name for a different 

price. A horse is a horse, but when you buy a horse the 
price you pay depends on how much he is worth. And 
often the horse that costs the most dollars is the cheapest. 

WELL, THAT'S JUST THE WAY in buying a machine. 
It isn't a question of how many dollars it costs you that 
counts. It's how much the dollar you spend gets for you. 

YOU CAN PAY A LOW PRICE but don't think that it 
is necessarily the cheap price. Remember, it's not what 
you pay, but what you get for your money that counts. 

THE AVERY COMPANY has always built quality 
goods. The reason we build them is because we believe 
you want that kind of goods, and we don't believe we are 
mistaken. Certainly, the increasing sales of Avery 
machinery would not indicate it. 

WE BELIEVE THAT YOU want machines that are 
built of good materials, with good workmanship, that have 
the best improved features for saving time, labor and 
money. That's why we endeavor to build that kind of 
machines. The price we ask for them is a fair price 
you get a big dollar's worth of actual value for every 
dollar you invest in Avery Machines. 

Avery Factory and Branch 

date equipment and a skilled *actory force. This, to- 
gether with the high grade mateiials we use and the 
originality of our designing department, is what makes it 
possible for us to produce machinery that supplies the 
needs for which it is built in such fine shape. 

OUR BRANCH HOUSES are located at central points 
in the middle and western states, and carry on hand a stock 
of complete machines with which to fill quick orders. 
Repair stocks are also carried at each Branch House to 
take immediate care of breakdowns, although breakages 
with Avery machinery are extremely rare compared with 
ordinary machines. If they were not we couldn't give the 
strong guarantees we do against breakage. 

sign improved and up-to-dnte machines, the factory to 
build the goods, and then we take care of you in the way 
of quick repair shipments and the help of service men 
after you get an Avery Machine. 

The Avery Policy 

IT'S LIKE THIS as we see it a question of mutual 
benefit. You need good machinery we are to supply you 
with what you need you should give us a fair return for 
doing so. 

THE AVERY ORGANIZATION is built up on this basis 
to serve the customer which means you by building 
the kind of goods you want and dealing with you on a 
square basis. The Avery Policy is "A Good Machine and 
a Square Deal." That's undoubtedly why it's one of the 
largest companies in the business and why this Company 
has had such a rapid growth. 

IF THESE METHODS appeal to you, we invite you to 
take up with us further the matter of your requirements. 
Write us a letter or call at our Home Office or any of our 
Branch Houses, Jobbers or Agents. 

THE AVERY IDEAL We propose that every Avery owner shall be, in so far as we are able to assist him, the best 
profit-making machine owner and the best satisfied customer of any man owning any make of machine i
