Illust. 1. This plow is set for one hundred per cent perfect work. Both bottoms
will turn furrows exactly the same width and depth. The hitch is at the correct
angle, neither too high nor too low, and a minimum amount of power will be
required to pull the plow. To obtain this result the adjustments noted in the
following pages are required.
The purpose of the rolling coulter is
to furnish a thin, sharp edge which
will cut trash, roots and tough soil
with a minimum amount of power.
While under usual conditions a plow
will do nearly as good work without
the coulter as with it,
it will require more
power because the shin
of the mold has a tearing
rather than a cutting
The position of the
rolling coulter with re-
lation to the plow bot-
tom has a great deal to
do with the quality and
appearance of the work.
In most cases the center
of the coulter should be
directly above the point
of the plow, as shown in
the illustration on this
page. The proper height
for the coulter depends
upon the depth of the
plow and the nature or
condition of the soil. In this illustration
(No. 2) the coulter is shown set for
plowing about six inches deep in
ordinary soils. Notice that the lower
edge of the coulter is about an inch
and a half above the point of the
For deep plowing, the rolling coulter
should be raised. It should not run more
than about three and one-half inches deep.
The position shown in Illust. 4 is about
right for plowing eight or nine inches deep.
Notice that as the coulter is raised it should
also be moved slightly to the rear, giving
the share a better chance to penetrate the
soil. If the ground is exceptionally hard
the coulter has a tendency to ride the plow
out of the ground when set too far ahead.
When a plow doesn't take to hard ground
as it should, see if the coulters are too far
forward or set too deep. For hard ground
center of coulter should set about 3 inches
back of point of share.
The position of the rolling coulter with
relation to the landside has much to do
with the quality of the work, especially
with the neatness of the furrow bank.
Under most conditions, the coulter should
be set § to f of an inch to the left of the
landside, as shown in Illust. 3. It can be
moved to right or left by loosening nuts
A and B and turning standard with a
large wrench as shown. Setting coulter
out prevents edge of furrow from crumb-
ling and preserves a better furrow bank.
Illust. 5. When the coulters are properly set, they will line up as shown above.
Notice the angle at which the offsets in the coulter shanks set — front one toward
the rear and the second and third toward the front.
Opening A "Land"
Illustration 6 shows
the opening up of a new
land with the last plow
running between six and
seven inches deep, and
the first one three to
four inches deep. This
setting will prevent a
high ridge even though
it is desired on the re-
turn trip to have the
first plow throw back
the opening furrow.
When opening a land,
the right hand or furrow
wheel must necessarily
be set higher than is the
case after the first round
has been made and this
wheel is running in the
furrow. The two levers
shown in Illust. 7 are
used to adjust the
depth and to level the
plow. To open a land,
the levers should be
about in the positions
shown. After the first
time around, the plow should be leveled
with the furrow wheel in the furrow,
and after that the levers should require
practically no attention until the land
is finished. Of course if there are tough
spots, or grades, where the draft is
exceedingly heavy, it may be necessary
to run the plow somewhat shallower.
On the Nos. 3, 4, 5,
and 7 Little Genius
plows these two levers
can be operated inde-
pendently of the power-
lift device. This feature
has the advantage that
should one of the bot-
toms encounter a stone
or root, the plow can be
backed and the bottoms
raised by hand. The
same thing can be ac-
complished on No. 8
Little Genius by backing
the plow a short distance
and raising the bottoms
with the power lift. This
permits the removal of
the obstacle, and the
plowing can then proceed
without leaving a skip.
Illust. 8. Showing proper hitch for 2-bottotn plow
One of the commonest sources of
excessive draft is the hitch between
the plow and the tractor. The draw-
bar of the plow should make, as nearly
as possible, a straight line between the
tractor drawbar and the center of the
load on the bottoms. If the hitch slopes
downward from the plow to the tractor,
unnecessary weight is thrown on the
front wheels, increasing the draft, and
wearing out the wheel bearings. The
line of hitch should slant slightly up-
ward toward the tractor.
McCormick-Deering tractor plow
hitches are now assembled for hitching
to the center of McCormick-Deering
10-20 and 15-30 tractors.
Since the center of draft in
a two-bottom plow is ap-
proximately 1 7 to 1 9 inches
from the furrow wall, the
center hitch is ideal under
average plowing condi-
tions. In the case of
the three-bottom plow
the center of draft is
approximately 24 to 26
inches from the furrow
wall, and hitching to the
center of the McCormick-
Deering 1 5-30 tractor is
correct under average
plowing conditions. Note
that the right hand trac-
tor drive wheel runs in
In hard plowing the center of draft
has a tendency to move to the right,
closer to the centers of the bottoms,
owing to the heavier mold-board
pressures. To overcome excessive land-
side pressure under these conditions, set
the plow hitch to the right. In very
shallow or very loose plowing the land-
sides may have a tendency to run away
from the furrow wall. To overcome
this tendency, and steady the plow,
adjust the plow hitch to the left. Under
extreme conditions it may be desirable
to hitch to right or left on the tractor
In hillside plowing it is often desir-
able to hitch the plow farther to the
right when throwing the furrow up-
hill than when going the
opposite way. Where the
hills are so steep as to
make frequent hitch ad-
justment necessary it is
recommended that the
plowman use the special
adjustable drawbar hitch,
which has a lever which
enables the plowman to
adjust the hitch instantly.
The weight of the bot-
toms should be evenly
counterbalanced by the
heavy tension springs in
order to make them lift
as easily as possible, either
by the operator or the power - lift
mechanism. It is easy to adjust the
tension of these springs. If the plows
raise too hard, loosen the lock nuts
(Illust. 10) on the adjusting bolts at
the ends of the springs and tighten
the second nut until the proper tension
is obtained as shown above. Spring A
adjusts the lifting tension on the axle of
the front furrow wheel, which is oper-
ated by hand lever C. Spring B adjusts
the lifting tension of the axle on the
land wheel, which is operated by hand
When the tension of these springs is
properly adjusted, the springs will assist
the lift in raising the bottoms and will
not in any way retard lowering.
With plows that depend entirely
on the weight of the bottoms to get
the bottoms into the ground, too much
tension on the springs may interfere
The Rear Wheel
The heel of the third plow should
run lightly both against the bottom
and the wall of the furrow. 1 1 should not
carry the full downward
pressure from the weight
of the rear end of the
plow nor the full side pres-
sure from the furrow.
It is easy to ascertain
whether the heel is bear-
ing against the furrow
bank or bottom by ob-
serving whether it is
leaving grooves and, if
so, how deep such
The heel of the plow
can be raised or lowered
by means of the set-
screw shown in Illust. 1 1 .
To make the adjust-
ment, first loosen lock-
nut and clamp bolt, then
turn the set screw in to
raise heel or out to
The rear furrow wheel should run
in the corner of the furrow, and be so
adjusted that it bears a part of the
weight of the rear end of the plow,
as well as a part of the side pressure
against the furrow wall. Also, this
wheel should have a lead of J to | inch
to the right. By "lead" we mean
that the edge of the tire should be
farther from the furrow wall in front
than in the rear. This will lighten
the pressure on the landside. If the
furrow wheel does not stand in proper
relation to the landside, that is, does
not lead away from the bank, it should
be changed. How to do this on the No.
8 Little Genius is shown in lUust. 13.
It is essential to good plowing
that the heel of the rear landside
bear lightly on the bottom of the
The Front Wheel
The notion prevails in many sections
that the front furrow wheel should run
against the bank of the furrow. This is
wrong. The inner edge of tire should
be about two inches from bank, as
shown in Illust. 12. In this position
the first plow will cut the same width
as the others. If wheel is run against
bank the front bottom will cut two
inches more than it should, throwing
additional draft on tractor and resulting
in an inferior job of plowing. Also, if
the wheel is run against furrow wall,
a slight deviation of the tractor from
the furrow wall causes wheel to climb
bank or cut against it in such a way
as to interfere with the work. The
wheel is run away from the bank to
provide against slight deviations of the
When difficulty is experienced in
covering trash, it is advisable to use
a jointer. It is important that the
jointer be properly adjusted. When
used in connection with a rolling coulter
as illustrated, its point should be set as
close as possible to the face of the coul-
ter without actually running against it.
Proper adjustment is easily obtained
by means of the two nuts, A and B,
and by the slotted hole in the end of
the jointer as shown in Illust. 14.
Loosening nut A slightly and tighten-
ing nut B will move the jointer away
from the coulter. To move it toward
the coulter, reverse the
A simple but very im-
portant adjustment is
provided for in the slotted
hole at the end of the
jointer shank as shown in
A, Illust. 15. This slot
permits moving the point
of the jointer toward or
away from the coulter.
The jointer should always
be adjusted as shown in
C, with the point close to
the coulter and with the
space between the jointer
and coulter widening to-
ward the rear. This pre-
vents weeds or trash from
wedging between the
coulter and jointer, as will
happen if the point is far-
ther from the coulter than
the rear of the blade. B
shows the wrong adjust-
ment, with trash wedged
between the coulter and
jointer blade. By loosen-
ing the two bolts which
hold the blade to the shank, it is easy
to get the right adjustment as shown
in C. The rear of the edge next to
the coulter should be about three-
eighths of an inch from the coulter,
while the point should be
as close as possible with-
out causing friction.
The use of the jointer
alone has been largely
discontinued, as in most
cases the combined coul-
ter and jointer does so
much better work.
Illust. 16 shows the
proper position of the
jointer in relation to the
shin of the plow, namely
about one-half inch to the
left. The jointer is moved
to the right or left as
shown in Illust. 17.
The heel of the jointer
share should run a little
above the top of the
ground. This will make
it cut a cleaner furrow
and will prevent it from
becoming fouled with
trash. The line A-B (in
Illust. 16) shows about
the depth the jointer
It is a simple matter to adjust the
position of the jointer with relation to
the shin of the plow. In order to move
the jointer farther to the left, loosen
nut A (Illust. 17) slightly, and tighten
nut B. In order to move it to the right,
reverse the operation.
To adjust the pitch of the jointer
with reference to the point of the share,
that is, to move it forward or back, the
set screw shown in Illust. 1 9 is turned
to the right or left, as the case may be.
Do not attempt to change the position
of the jointer by means of the set screw
when the two bolts which hold the
jointer to the plow beam are tight.
Slightly loosen the nuts on the two
bolts which hold it in place, then turn
the set screw until the jointer is in its
proper position, then tighten the nuts.
The set screw only changes the pitch
of the jointer.
The rolling coulter yoke permits a
slight turning movement, either to the
right or left. Since this joint is in a
position where it comes in contact with
a great deal of dust and grit, more or
less wear is likely to occur. There should
not be unnecessary looseness at this
joint as two bolts, A and B (Illust. 18),
are provided for taking up wear.
It does not pay to plow
with dull or worn-out
shares. It is always de-
sirable to have at least
one complete set of spare
shares (two sets are bet-
ter) so that one set may
be used while the other is
being sharpened. Prac-
tically all tractor plows
are now equipped with
It requires but a moment
to unscrew the nut A far
enough so that the front
end of the bolt slips over
the head of the bolt on the
share. One turn on the
nut B at the wing of the
share and the share slips
off, after which a new one can be slipped
into place, and the nuts tightened.
A new share is made with what is called
suction, that is, it is made with the point
of the share pointing slightly downward.
This is done to make the share penetrate
readily. As the point wears off, this suction
is gradually lost and difficulty will be ex-
perienced in getting the bottoms to take to
the ground. To repeat, it does not pay to
use dull shares. It costs more in fuel, time,
and patience than the cost of resharpening
justifies. (See page 20.)
Rear Wheel Scraper
Where the soil is sticky, the rim of the
rear furrow wheel is quite likely to become
caked with mud, thus increasing the diameter
of the wheel and changing the adjustment
of the plow. In order to prevent the ac-
cumulation of mud on the rim
and to keep the diameter of
the wheel uniform, the wheel
scraper should be adjusted so
that the point is at the center
oif the wheel rim and about
one-fourth of an inch from
On a plow whose furrow axle
is held against side play by
collars, as shown in Illust. 20,
the collars must be kept tight
on the axle — there should be
no side play at the points
indicated by the arrows.
Under some conditions the use of the hanging cutters is desired. The proper
position for these under most conditions is as shown in the Illust. 23, with
their points about one inch
above the points of the
P' i'^ ' ' ■ * ', shares and with the cutters
fX I C . ^jj slanted backward at a
* ^^™ shght angle.
The position of the hang-
ing cutters with relation to
the points is shown in
Illusts. Nos. 24 and 25.
Illust. 24 shows the prop-
er position of the hang-
ing cutter with relation to
the point of the plow,
namely about one-half inch
to the left and with the
left-hand side of the cutter
parallel with the landside
of the plow. The adjust-
ment of the cutter from
side to side is shown in
Illust. 25 shows how the
position of the hanging
cutter can be changed with
relation to the point of the
plow. By loosening nut A
and tightening nut B the
edge of the cutter is moved
toward the left.
To move it toward the
right the operation is re-
It is a mistake to assume, because a
plow moves slowly and has few moving
parts, that oil and grease are not neces-
sary. The bearings on tractor plows
work under severe conditions. Grit
causes wear and no plow can do first-
class work when its wheel bearings are
worn and wobbly. When there is plenty
of oil in the bearings, dust cannot get
in, for as the oil works out it carries
the dust with it. McCormick-Deering
tractor plows are now being equipped
with oilers of the Zerk or Alemite type
at points where frequent oiling is
The three wheel hubs are provided
with screw caps designed to be used as
grease cups. Fill these frequently and
force the grease into the bearing. At
the beginning of the season it is well to
squeeze in several capfuls.
While the wheels are equipped with
hard oil screw caps, which force the
grease back into the bearing, the
grease is very likely to work away from
the sand bands. A covered oil hole is
provided on the sand bands and these
should receive frequent oiling.
Keep the coulter bearings oiled —
the coulter can't do first-class work
when the bearings are worn.
The rear wheel (Illust. 29) sets at
an angle, with the wheel box pointing
downward. This means that the grease
would naturally work away from the
sand band, and frequent oiling will
prevent friction at this point.
Principles of Draft in Tractor Plows
The outstanding advantage of plowing with
tractors is, of course, economy — maximum
production per man. Tlfis is so well under-
stood now that we shall not here go into that
phase of the subject. Another advantage is
the ability, with a tractor plowing unit, to get
the plowing and tillage done in time for season-
able planting, which generally results in better
crops, and greater yields. Not only is the
hourly accomplishment of a. tractor plow
greater than that of a horse plow, but the
tractor, unlike the horse, can be worked two
or three shifts a day, and often is.
These, and other advantages, have been
discussed so much that the quality of tractor
plowing and the simplicity of using a tractor
plow, as compared with horse plows, too
frequently have been overlooked.
Tractor plowing has a uniformity of ap-
pearance, depth, and quality which can be
achieved with horse plows only by very ex-
perienced plowmen. And the adjustments re-
quired to adapt a tractor plow to varying con-
ditions are simpler and more quickly made.
Stated from another angle, there are fewer
chances for failure to do good work with a
tractor plow than there are with a horse plow.
Yet there are conditions encountered in
tractor plowing which call for some knowledge
of the principles involved in plow design and
operation, if the plow is to be given a chance
to do its best work under all conditions. Not
infrequently plows are condemned for poor
work when the trouble arises entirely from
wrong hitch or faulty adjustment of equipment.
The Center of Draft
While it is not necessary that the tractor
plowman possess the information which is
presented here, he will find it easier with this
knowledge to do more nearly perfect vyork.
Plowing must be done under an extremely
~^^(\ of Load
llluBt. 31. The cross indicates the approxi-
mate location of the center of load on a
plow bottom under average plowing con-
wide range of conditions. When tractor plows
leave the factory they are set for average
conditions. Naturally, some of them may need
adjustment to meet special conditions on the
farms they happen to reach.
One of the most frequent causes of failure
to do good work is a wrong hitch. Nor does
the damage caused by wrong hitch stop with
the work. Nearly always there is also undue
wear on the plow, and heavier draft, resulting
in higher fuel cost per acre of plowing.
To be able intelligently to hitch a plow to a
tractor it is an advantage to have an idea of
the location of the center of load on the plow
bottoms and its relation to the drawbar of
the tractor, or, in plow parlance, the line of
draft. If the center of load would stay in one
place for all conditions, hitching would be
greatly simplified, but it won't.
Most authorities agree that in a 1 4-inch bot-
tom, under average conditions and at average
depth, the center of load is 2 inches from the
shin, and not far above the joint between the
moldboard and share.
Illust. 32. Of the dotted lines the straight line shows the true line of draft with respect to the
height of the plow hitch and the tractor drawbar. The other dotted lines show high and low
hitch. The bent lines will straighten under load and the working of the plow will be aSecled
Results of Too High Hitch
The line of draft is an imaginary line from the
center of load on the bottoms to the point of hitch
at the tractor drawbar. Regardless of how high
or low we hitch, that line is going to do its best to
straighten out. If we hitch too high on the plow,
too much weight is carried by the front wheels of
the plow. The result is worn wheel bearings, and
a tendency of the bottoms to "stutter" or bob along
on the noses of the shares.
Hitching too high is also likely to cause poor
scouring. The reason for this is that when abottoin
is tipped on its point, the angle of the bottom with
reference to the furrow slice is changed — made more
abrupt — the soil encounters the turning surface of
the moldboard too squarely to push itself off. Also,
the moldboard being too abrupt, that is, too straight
up, the furrow slice breaks down before it should
and passes under the wing of the board instead of
turning over as it should. Perfectly good plow bot-
toms have been condemned for failure to scour,
and for failure to turn the furrow, when the trouble
was due entirely to a hitch too high on the plow.

the line of draft in a 3-
bottom plow with 14-
inch bottoms, and _the
correct setting of hitch
when the plow is pulled

the right locates the line
of draft in a 2-bottom
plow with 14-inch bot-
toms, and shows the cor-
rect hitch for usual con-
If Hitch Is Too Low
Hitching too low on the plow has the opposite
effect. Too much weight is thrown on the rear
wheel, or on the bottom of the rear landside if there
is no rear wheel, and the front wheels do not carry
their portion of the weight. Resistances which
should be converted to a rolling load must be' over-
come as friction, and again there is heavier draft.
The Tractor Drawbar
It is well to remember that lowering the tractor
drawbar is equivalent to raising the hitch on the
plow, and that raising the tractor drawbar is
equivalent to lowering the hitch on the plow.
Now we'll suppose we have plowed around once
and that we have started on the second through
and have the wall of a previously made furrow from
which to measure. From this we shall locate the cen-
ter of load for 2-, 3-, and 4-bottom plows, assuming
that the plows are equipped with 14-inch bottoms.
The point 2 inches from the shin, the center of
load on the first bottom, is 1 2 inches from the furrow
wall. The center of load on the second bottom
is 12 inches, plus 14 inches, or 26 inches from
the furrow wall. The center of load on the
two bottoms is, therefore, half way between 1 2
and 26 inches, or 19 inches from the furrow
wall. The center of load on a 3-bottom plow
is the center of load of the middle bottom,
which, as we have just shown, is 26 inches from
the furrow wall. In other words, when we
add a 14-inch bottom, the center of load of
the gang shifts 7 inches farther from the fur-
row wall, or half the width of the bottom
added. Add 7 inches to 26 inches and you
have 33 inches for the center of load in a
4-bottom plow. The true line of draft is
straight forward from the center of load. For
plows with 12-inch bottoms the lines of draft
are, from the furrow wall, 16 inches for the
2-bottom, 22 inches for the 3-bottom, and 28
inches for the 4-bottom.
Conditions Affecting Line of Draft
Keep in mind that these locations are based
on the more or less arbitrary assumption that the
center of load is 2 inches from the landside or
furrow wall. Often it is farther to the right than
that, and sometimes it is nearer the landside.
For stubble plowing, the figures are very close.
In hard plowing, or heavy sod, more pressure is
thrown on the moldboards, and the center of load
may shift considerably toward the centers of the
bottoms. Conditions which might cause the
center of load to shift toward the left are loose
soil, shallow plowing, blunt shares, plowing in
root-matted soil without rolling coulters, etc.
Better Than Guessing
While it is always possible to arrive at a fairly
correct adjustment of a plow by trial, the plow-
man who knows about where the center of load
is located in his plow and the relation of the true
line of draft to the line of hitch, is able more
quickly and intelligently to make the adjust-
ments necessary to adapt his plow to the con-
ditions under which it has to work. Horse plows
are far more sensitive to side draft than tractor
plows, yet it is helpful to know these things even
in the operation of tractor plows.
Instruction books supplied with McCormick-
Deering tractor plows show how to assemble the
hitches for hitching to the centers of McCormick-
Deering tractors. These hitches are correct for
average conditions. By applying the principles
outlined above, the user can recognize the effects
caused by shifting of the true line of draft, due
to unusual conditions, and adjust the hitch to
meet them. If there is too much landside pres-
sure, leading the rear wheel away from the furrow
wall or hitching farther to the right on the tractor,
drawbar will hold the landside away and make
the plow run lighter.
Hitching Too Far to Right
If the hitch is too far to the right on the plow
when hitched to the center of the tractor, shift-
ing the hitch four inches to the left on the plow
and hitching in the first hole to the left of center
on the tractor drawbar will favor the plow,
while the effect on the tractor will be scarcely
noticeable. We have shown the 3- and 4-furrow
plows hitched this way because we believe
such a hitch covers a wider range of plowing
conditions. It should be noted that a tractor
plow is not sensitive to slight off-side hitch
under ordinary plowing conditions, and that,
if the center of load on the plow does shift,
the shift is usually in favor of the hitches
Illust. 35. This shows the
proper hitch for a 4-bottotn
plow behind a 15-30 when
the right tractor drive wheel
is run in the furrow. Under
heavy draft conditions it is
sometimes desirable to run
both tractor drive wheels on
shown. That is, as the plowing gets harder,
the center of load on the bottoms shifts closer
to the line of hitch.
When Tractor Is Run On Land
Often when plowing in loose, crumbly, or
marshy land, it is desirable to run the tractor
on the land. When this is done it is customary
to hitch in the first hole to the right of the
center of the tractor drawbar, which is some-
what to the left of the center of draft of the
plow. While we can't always hitch in the true
line of draft, knowledge of where that line is
helps the plowman to understand the action
of his plow and to correct adjustments to meet
conditions. More or less landside pressure
results from running the tractor on the land,
but it can be counteracted by leading the rear
wheel (on three-wheel plows) away from the
The Front Furrow Wheel
Probably the best evidence of whether a
plow is hitched right laterally is to observe
the land wheel. If this wheel is running
straight, it indicates proper lateral hitch.
If the plow is hitched so that the front bot-
tom is cutting its correct width and the coulters
are set right, the furrows all lie alike and
there is a uniformity of appearance which
cannot be duplicated by the average plowman
Soil On Wheels Affects Depth
If the soil packs on the rims of the tractor
drive wheels, and on the plow wheels, the
depth of plowing is affected, and the addi-
tional wheel diameter should be allowed for
in the adjustment of the levers. Ridging the
soil often results from failure to level the plow.
The depth and leveling levers work together —
the plowman should always be sure to use the
leveling lever when he makes any appreciable
change in the adjustment of the depth lever.
The rear-wheel scraper should be adjusted to
keep the wheel clean. One of the functions
of the rear wheel on a three-wheel plow is to
tilt 0/ tractor

inch bottoms) hitched to the Farmall.
carry the landside lightly in the bottom of the
furrow. If the soil is allowed to pack on the
wheel, the rear end of the plow is raised too
high for good work.
We have tried in this article to cover the
factors having most to do with quality and
appearance of tractor plowing. Much that
we have said applies to plowing with horses.
Whereas, it requires an experienced plowman
to do really first-class work with a horse plow,
any man who can apply a few simple rules
in setting his plow, and who can drive a tractor
straight, can do first-class work with a tractor
How to Sharpen a Steel Plow Share
Modern plow manufacturers have expended large sums of money
for the purpose of giving the farmer the best plow shares that can be
produced. Refrigerating plants have been installed to maintain the
tempering bath at a uniform temperature ; the best three-ply soft center
steel that can be produced is used. In fact, nothing is left undone
that will produce a plow share so hard that it will scour and polish
like a mirror, yet withstand the strain and shock incident to heavy
plowing; and all that has been accomplished along the lines above
mentioned can be undone in a few minutes by the first man who
sharpens the share, either through lack of knowledge, or carelessness.
The average blacksmith, after removing the share from the plow,
plunges it into a big broad fire to heat, preparatory to sharpening, oft-
times setting it on edge in the fire. This is wrong, as it permits the
heat to extend over the entire surface of the share, withdrawing the
hardness that the manufacturers were so careful to conserve. It also
causes the share to warp and lose its original shape, causing annoy-
ance in replacing the share on the plow.
To sharpen a plow share properly:
Build a fire on the forge suitable for this particular work. This is
done by banking the fire, allowing only a small opening in the side
for the blaze and heat to escape. Commence with the point of the
share. Insert this into the fire just far enough to heat the part you
wish to draw, never permitting the heat to extend farther back on the
share than is absolutely necessary. Draw this down to the proper
shape and thickness, which should be as near the original bevel as
possible. After the point has been finished, work back toward the
heel or wing of the share, never heating more than 1 J inches from the
edge and 2^ inches wide. It is important to keep hammering after
the steel has changed from a red heat to a black as this makes the
edge tough and hard, giving a wearing surface that will last much
If once down the share is not sufficient, reheat; but confine the
heated part to the above measurements. In working along the cutting
edge, keep it straight. In so doing you will avoid having to go back
and reset the edge.
It is impossible to give the exact amount of wing bearing on walk-
ing plow shares, but it should be from 1 to 1 f inches, according to the
size of the plow. Shares used on wheel plows should have no wing
bearing. These instructions refer to both hard and crucible steel shares.
Suction of Plow Shares
Worn Shares Waste Time,
Money and Patience
It costs more to plow with worn shares, a
great deal, than it does to sharpen them — it
takes more power — it takes more time and
results in excessive wear on the plow, particu-
larly the wheel bearings if hitching high on the
plow is resorted to to make the plow take to
the ground, as it often is.
There is more to reconditioning a plow
share than merely restoring the edge. If you
will hold a yardstick under the bottom edge
of the landside of a new plow, with the edge
of the yardstick touching the point of the
share and the heel of the landside, you will
lUust. 38. Side view
of a plow bottom in
which suction is ob-
tained by bending
the nose of the share
note that at the point where the share joins
the landside there is approximately one-half
inch clearance. This is known as bottom, or
down suck. It is the characteristic which
makes the plow take to the ground. You can
check the bottom suck in a bottom having a
short landside by placing the bottom on a
level surface and placing a half-inch block
under the heel of the landside.
Too frequently when the shares begin to
lose their suck and the plow begins to run
out on the slightest provocation, the plowman
tries to overcome the difficulty by raising the
hitch on the plow. Now if you lay a rail
over a block and push down on one end, the
other end is bound to come up. That is just
what happens when you hitch too high on the
plow. The frame of the plow is the rail and
the plow wheels are the block. The result of
hitching too high is that while you do "throw
the plow on its nose" you raise the heels of
the' landsides, you lose the steadying effect of
the landsides, the plow has a tendency to kick
to the left, and there is excessive wear on the
front furrow and land wheel bearings.

This is approximately

bottoms. Notice that the
under side of the gunnel is
a straight line. The nose
of this share should not
be bent down by the
Two Types of Shares
In some plows bottom suck is secured by
bending the nose of the share down after
sharpening. This is usually accomplished by
placing the share on an anvil, with the nose
projecting over, and striking the nose with a
hammer. In some plows, the bottom suck is
determined by the angle of the share with
relation to the bottom. In this type it is
necessary merely to set the share on a face-
plate after sharpening and bring the bottom
edge of the landside portion of the share
(gunnel or stub landside) to a straight line.
It is very necessary, therefore, to know which
type of share you are using, for if the latter
type of share is given additional suction by
bending the nose down, the additional penetra-
tion will more than likely result in a strong
tendency of the plow to bury itself.
The nose of a new or properly reconditioned
share also points slightly "toward the land."
This characteristic is called side suck and is
built into the share to make the bottom "hold
its land;" that is, cut its proper width.
Reconditioning a share means sharpening
and restoring the original bottom and side
suck. Probably nine-tenths of the trouble which
some folks have in making their plows work
properly is due to worn shares. If your plow
hesitates in taking to the ground, examine the
shares to see if they have lost their bottom suck.
In reconditioning the share the point should
be brought out to its original length.

Methods for Laying Out Lands and
Plowing With Tractors
In order that tractor users might
receive the highest possible degree
of satisfaction from their outfits,
our publication Tractor Farming,
published in the March issue of
1919, an article entitled "Plowing
With Tractor Power." The accom-
panying illustrations and text are
taken from that article. We hope
this information will prove of
benefit to those who receive this
Two Methods of Tractor
Broadly speaking, there are two
distinct plans followed when plow-
ing with a tractor. In one, the field
is laid off in lands, to be plowed
out in straight furrows. The plo^Vs
are raised at each end of the field, headlands
being left for turning. Headlands are plowed
last. (See lUusts. 40 and 41.) 1 1 is customary to
leave the same space on each side as is allowed
for headlands, to permit plowing around the
field when finishing, as shown in Illust. 41.
If this is not done the headlands are plowed
out as lands, either by back-furrowing or
plowing them out to a dead furrow.
In the second plan the entire field is plowed
by driving round and round without taking the
plows from the ground at all, or for only a few
feet, while turning corners. The outfit either

lUust. 41. Most farmers leave the same space at the
sides of the field as at the ends and then plow round the
entire field in finishing up. If desired, the entire width
may be plowed in lands and the headlands plowed out
separately as individual lands.
Illust. 40. Plowing the center of the field out in lands is
the most comnion method. This shows one of the best
plans for plowing out the lands in order to reduce idle
running at the ends and eliminate about half the dead
furrows. Plow symbols show direction dirt is thrown.
starts in the center of the field and works
toward the outside, or starts at the outside
and works toward the center. (See Illusts.
42 to 45 inclusive. )
The first plan, that of laying off the fields in
lands, is by far the most common and some
variation of it will probably be found most
satisfactory on the average farm. The prin-
cipal disadvantages of the system are that it
involves considerable idle travel at the ends,
and also leaves a number of dead or "clear-up"
furrows. While there are some areas where the
rainfall is heavy and the dead furrows are con-
sidered a desirable aid to drainage,
in most sections dead furrows are
more of a disadvantage than other-
The majority of farmers, however,
recommend some variation of this
first general method, apparently
considering that its advantages
more than offset its disadvantages.
Nevertheless, unnecessary trav-
el adds somewhat to cost and
reduces the amount of plowing
which can be done in a given time,
and it should therefore be kept as
low as practicable. The narrower
the lands the less the amount of
idle traveling required, but the
greater the number of dead fur-
rows. There is a simple plan of
Sl^ ^^J^ _J^ ,_mJ~Z^ alt _A, -itS;!^

instead of two which would result
from plowing each land out by back-
furrowing. A field laid off in five
lands will have but two dead furrows
instead of four.
Illust. 42. Plowing round and round, turning to the
left and throwing the soil tovrard the fence without rais-
ing the plows from the ground. Note the wider furrows
at corners which means poorer plowing, but this method
eliminates all idle running.
plowing out lands, however, which will reduce
the number of dead furrows by approximately
one-half without increasing the size of the lands
or the amount of idle travel, and every farmer
who plows in lands should be acquainted with
Reduce Dead Furrows
This scheme consists of plowing out alter-
nate lands by back-furrowing (in some parts
of the East this is known as "striking a ridge"
and plowing around it), and then plowing round
each intermediate land to a dead furrow. In
other words, every odd land (first, third, fifth,
etc.) will be plowed round by turning to the
right, throwing the soil to the center, while
every even land (second, fourth, sixth, etc.)
will be plowed out by driving
round it, turning to the left,
throwing the dirt toward the
sides of the land, and finishing in
the center, leaving a dead furrow.
When following this plan the first
and third lands are completed
before starting the second, and
the fifth land is plowed before
starting on land four, and so on.
Illust. 40 shows this method of
plowing out a field of three lands.
As in all the illustrations, no
attempt was made to draw fur-
rows even approximately to scale
— the lines merely indicate the
line of travel of the tractor, and
1 1 pays to take care in laying off
the lands, since inaccuracy of locat-
ing the lands or insufficient mark-
ings cause considerable inconven-
ience when finishing up the work,
at the same time spoiling the looks
of the work. Very often the work
of laying off and marking the field
for plowing can be done at odd
times — in fact, several weeks before
the work is started. It pays to use
plenty of markers — it doesn't take
much longer, may save a lot of time
in finishing, and is almost sure to
result in better work. It is much
easier to plow a straight furrow by
keeping markers injine than driving toward a
single marker at the other end of the field.
The accuracy of laying off the field can be
increased by constructing a measuring frame
of light strips of wood in the shape of a letter
"A" with the lower points the exact widths of
the strip turned by the gang plow or some
multiple of this width. The use of this device
will usually make it possible to finish it
up evenly without having to plow extra
When a field is to be plowed in lands it is
always advisable to have a mark at each end,
as a guide for raising and lowering the plows.
This mark can be a single furrow plowed at
each end of the field. These furrows should
be as shallow as possible to avoid jolting the
tractor and plow when driving across them
and the furrows should be thrown in toward
the center of the field. A mere scratch parallel
with the fence or boundary of the field is all
that is required.
By following this plan a field in
which there are only three lands
will have but one dead furrow.
Illust. 43. Showing how some farmers plow out the
corners first when they wish to plow round and round the
field in the manner shown in Illust. 42. This permits all
the work to be done with the tractor and makes a gradual
curve for turning.
Plowing Round and
The system of plowing round and
round the held without taking the
plows from the ground, or for only
a few feet at the comers, has the
advemtage of greater speed and a
minimum of idle travel. The prin-
cipal objection is the quality of the
work at the corners. If the plows
are left in the ground all the way
around the work done on the turns
will not be first class unless a very
wide curve is made, and a wide
curve leaves more unplowed land in
Turning to the Right
If the curve at the corner is very
gradual the tendency to cut wide or "cut and
cover" is not so pronounced and may be
When turning to the right the bottoms will
not cut full furrows and therefore will not do a
really first-class piece of work, although the
quality will not be lowered so greatly as when
turning to the left. In a large field, however,
it will result in leaving considerable ground
in the comers by the time the furrows on the
ends and sides have reached the fence. In
order to avoid leaving a considerable amount
of unplowed land at the comers, therefore,
extra furrows should be plowed at the corners
to bring them out even. This should be done
as near the end of the job as possible when
there is just room enough left for turning on
the unplowed land, eind then plowing enough
extra furrows around the curve at each corner
to bring the corners practically the same dis-

tance from the fence as the side and end fur-
rows. By again plowing round and round the
entire field it will then be possible to plow out
practically every foot of the field with the
Turning to the Left
When plowing round and round, making
left turns, throwing the soil toward the fence,
the curve should be gradual at the corners so as
to avoid having to run the tractor off the land
or into the plowed land in order to make the
turn without the furrow wheel of the plow
leaving the furrow. To do this the corners
should be plowed out first until a wide curve
has been made, as shown in Illust. 43. The
field can then be furnished by plowing round
and round, and practically every foot can be
plowed with the tractor.
A variation of the plan of
plowing round and round the
field is shown in Illust. 45. As
can be seen, the field is plowed
round and round with the plows
raised at each corner while a
half-turn is being made, but
instead of plowing close to the
fence on all four sides of the
field a headland is left at the
two ends, the same width as the
strip between the ends of the
furrows where the plows are
taken out in turning. When the
unplowed land in the center of
the field is twice the width of
these headlands and corner
strips, the corners and head-
lands are plowed out by driving
round and round, as shown in
Illust. 44. This avoids making
lUust. 46. Method of finishing a land plowed as shown
in Illust. 45. This shows the ends, corners and center
plowed round and round to a dead furrow in the center,
starting the finishing furrowrs at the point mariced
"start.** If desired, it can be plowed out by back-
short turns in the corners of the field, which
are necessary in case the headlands are not left.
This plan permits the entire field to be
plowed with the tractor just as close in the
comers as the tractor can go, and that is about
as close as it can be done with horses. While
the method is best suited for plowing with left-
hand turns, that is, throwing the furrows
toward the fence, it can be used very satis-
factorily for throwing the soil toward the
center of the field, if the field is carefully
measured off so as to permit starting at the
proper points at the center.
Don't Plow Same Way Every Year
Most plowmen like to throw the soil toward
the fence one year and toward the land the
next. This can easily be accomplished by either
of the two general methods of plowing describ-
ed. If the center of the field is plowed out in
lands the headlands and the strips ^^____
on each side can be plowed out by ^ -=S>- '~
driving around the field either to the
right or to the left. When the meth-
od of plowing round and round is
used this can be alternated by start-
ing at the fence and turning to the
left one year and beginning at the
center and plowing round and round
to the right the next, whether the
plows are left in the ground all the
time or raised in the corners.
Most fields of irregular shape can
be plowed using either of the two
general methods described by exer-
cising a little thought in adapting
them. Plowing round and round.
making left turns, will probably
be as satisfactory as any method
for the first time. Plows can
either be raised at the corners
or left in the ground, as desired.
By making some sort of a mark at
the center of the field as located by
this method of plowing, the next
time the field is plowed the work
can be started at these points. If
the field is plowed out to a dead-
furrow, this furrow can usually be
located and used as a guide for
starting plowing and turning to
the right. Plowing in lands can
usually be followed to good advan-
tage in fields having two parallel
sides by laying off the lands par-
allel with the parallel sides and
raising the plows at the ends equally distant
from the fence at all points.
Plowing Round and Round Turning
Illust. 47 shows a method occasionally used
but involving a large number of turns with the
plow idle. It is used by some plowmen alter-
nately with the methods shown in Illusts. 42 to
45. The quality of the plowing compares very
favorably with that done by any other method.
As can be seen in the illustration, the center
of the field is located as in Illust. 44 and the
land started by back-furrowing. After the land
is several feet wide, furrows are plowed across
the end at each round, complete turns being
made at the four corners by looping to the left.
When there is no longer room left for turning
at the corners, the remaining strip can be
plowed out as shown in Illust. 41.
Illust. 47. Method sometimes practiced alternately
with that shown in Illust. 45. Points 1 and 2 located as in
Illust. 44 and a land back-furrowed a few rounds after

Illust. 48. The McCormick-Deering 15-30 — a powerful tractor for big-scale farming.
The McCormick-Deering 10-20 and 15-30
tractors have an abundance of dependable
power for the heavy plowing and seed-bed
preparation jobs. They pull large-scale harvest-
ing equipment and operate the many belt-
This low-cost, heavy-duty power places all
farming operations on an efficient, low-cost
basis. Elqually as important as disposing of
the heavy work is the ability of these tractors
to keep all farm operations on schedule, over-
coming weather delays and other handicaps
that may occur.
These tractors are McCormick-Deering con-
struction from radiator to drawbar and are
popular because of many distinctive features.
Included among these are removable cylinders,
factory-sealed governor, combination manifold
for using either kerosene or gasoline, oil filter,
air cleaner, one-piece main frame, and unit
construction. The unit construction feature
is invaluable in tractor design. Any unit —
engine, clutch, transmission, final drive, etc. —
can be removed without disturbing the adja-
cent units. Three forward speeds of approxi-
mately 2, 3, and 4 miles per hour meet all
working conditions, whether in the field or on

The McCormick-Deering TracTracTors —
Model T-20 and Model T-40 — are the crawler-
type members of the McCormick - Deering
tractor family. They are the most accessible
crawler tractors built. The rugged construc-
tion, combined with proved engineering prac-
tices and modern alloy steels, assures crawler
tractors that meet McCormick-Deering stand-
ards of performance, economy, and durability.
Their conveniently located controls and the
upholstered cushion seats are features which
contribute to the comfort of the operator and
result in a bigger and better day's work.
McCormick-Deering TracTracTors are com-
pact units which operate in close quarters. The
T-20 is especially adapted to working under
low-hanging trees, in orchards, and similar
work. More than forty ball bearings assist in
providing an unusual degree of transmitted
power in the TracTracTors. The steering
clutches and steering brakes located in the rear
compartment of the main frame introduce an
innovation in efficient steering performance for
track-type tractors. Wherever the going is
uncertain, the load heavy, and the work dif-
ficult, TracTracTors will do the job.

The Famous FARMALL
Now in Three
lllust. 53. The regular Farmall, the original
successful row-crop all-purpose tractor.
The regular FARMALL, the original row-crop,
all-purpose, two-plow tractor, meets the require-
ments of the average farm. It pulls two 14-inch
bottoms, wide tillage tools, two and four-row
cultivators, four-row planters, etc. Broadly, the regu-
lar FARMALL fits the farms in the quarter-section
class. It supplies fast, economical, dependable power
for all field and belt operations. It also provides
power through the power take-off for corn pickers,
binders, potato diggers, etc.
The FARMALL-30 is the three-plow size. It
meets the power requirements of the farms in the
200 to 300-acre class, where the power demand is
heavier, due to unusual soil conditions, or larger
tillage combinations. It supplies ample power
for two-row corn pickers, two-row potato diggers,
harvester -threshers, etc. It is a handy tractor
for the row-crop farm, and a husky, versatile
tractor for any farm.
FARMALL 12, the newest member of the
famous FARMALL line, is the tractor for the
smaller row-crop, or the very small intensively
worked farms. It pulls one 16-inch, or two 10-inch
bottoms, and tillage tools of like drawbar demand.
Already it has made a name for itself as a two-row
cultivating tractor, and many tractor
users operating larger tractors are buy-
ing the FARMALL- 12 for use as an
auxiliary tractor. A gallon of gasoline
an hour or a little over, is all the
F-12 needs on the average job, which
makes it a wonderfully economical
tractor on all drawbar and belt work
within its capacity range.
