A PRODUCT OF
POST HOLE DIGGER
ASSEMBLY AND OPERATING INSTRUCTIONS
The Series 903 Ford Post Hole Digger is designed
for use with Ford and Fordson Tractors. It mounts on
the tractor lower links and the hydraulic lift rocker as
shown in Figure 2. The digger is operated from the
tractor seat and is driven by the tractor P.T.O. at the
540 rpm speed only.
Maximum digging depth of all Ford Augers is approxi-
mately 42 inches, making it ideal for digging fence
post holes and for use in construction work to dig
holes for pilings or footings.
Augers are sold separately, and are available in a
wide variety of sizes (diameter) as detailed on page
4- All augers are 42 inches long and are provided
with either a plain or serrated cutting edge.
This manual contains information pertaining to the
assembly, lubrication, and operation of the Series
903 Post Hole Digger. Read it carefully before
attempting to assemble or operate the digger.
The Ford Post Hole Digger is shipped in one Bundle,
No. 22-63. Before assembling the unit, check the
parts against Figure 1 and the following list to make
certain that all parts are present.

Centering Lever & Control
1. Secure the lifting link (12), Figure 2, to the frame
with the long pin (6), Figure 1, and cotter pins.
Make certain that the control handle attaching
ears are slanting forward.
NOTE: The forward set of holes (A), Figure 2,
in the frame is used for row crop tractors, while
the rear set of holes (B), is used for general
2. Disconnect the gear box from the frame by re-
moving the long pin (2), Figure 2. Attach the
centering lever (3), to the top of the gear box with
the two bolts provided on the gear box. Realign
the gear box with the frame and install the pin
(2), as shown in Figure 2.
3. Secure the control handle (1), Figure 2, between
and lifting link ears (5), with the drilled pin and
cotter pin provided.
Ford and Fordson Dexta Tractors
1. Attach the lifting link pins (10), Figure 2, to the
tractor lower links and secure with linch pins.
2. Attach the frame ball socket assembly (9), Figure
2, to the tractor rocker assembly with the pin
and linch pin provided on the tractor. The lower
hole in the rocker will give the most ground
3. Fit the auger (7), Figure 2, on the drive spindle
and secure with the 7/16" x 4" hex head shear
bolt (6), lock washer, and nut provided.
4. Extend the universal drive shaft (11), Figure 2,
and coat it with grease, then slide it back in the
5. Disengage the tractor P.T.O. and remove the
P.T.O. cap. Turn the P.T.O. shaft manually until
the hole is aligned with the spring loaded joint
on the universal drive shaft and slide the drive
shaft over the P.T.O. shaft until the pin is locked.
NOTE: The universal drive shaft on the Ford
Post Hole Digger is designed for use on tractors
having a P.T.O. drive shaft of 1-3/8" diameter.
Tractors having a P.T.O. drive shaft of 1-1/8"
diameter must be adapted for use by installing a
P.T.O. Coupling Adapter, Part No. 231082.
Secure the coupling with a 5/16" x 2-1/4" bolt.

NOTE: Assemble the Ford Post Hole Digger in the
same manner as outlined for Ford Tractors, with the
lift link in the rear holes (B), of the frame support
(13), Figure 2.
1. Adjust the tractor hydraulic lift leveling rods to a
length of 24 inches to obtain auger tip ground
clearance of approximately 10 inches.
2. On F.M.D. and F.P.M. Tractors, set the tractor
leveling rods in telescoping position by reposi-
tioning the leveling rod sleeve pin EIADKN- 995250.
3. Place the leveling rod clevises in the forward
hole in the tractor lower link assemblies.
4. Lengthen the check chain linkage to permit
closing the tractor lower links to a minimum of
NOTE: Remove the Buffer Bar, ElADKN-995309,
on Fordson Tractors equipped with an. automatic
clutch release prior to post hole digger instal-
5. Position one spacer, Part No. 221799, in each of
the ball sockets of the tractor lower links, then
insert the post hole digger lifting link pins through
the spacers and secure with linch pins.
6. Position an NCA-22218-A Spacer in each side of
the tractor upper link support bracket, then attach
the frame ball socket assembly to the clevis.
Insert the pin, Part No. 100918, through the
spacers and the front link and secure with the
self-locking internal hair pin, Part No. 111856.
To complete the installation procedure, follow steps
3, 4, and 5, under Ford Tractors.
There are three lubrication fittings on the Ford Post
Hole Digger. One fitting is provided on each uni-
versal shaft joint and one on the shaft tube. Lubri-
cate these fittings with a good grade of grease after
assembly and every eight hours of operation thereafter,
or more often if required.
The gear box is shipped less oil and should be
filled with 2 quarts of SAE 90 EP oil. To fill the gear
box, remove filler plug (4), Figure 2, pour 2 quarts of
Post Hole Digger Assembled on Tractor
SAE 90 EP oil into box. Install the filler plug. Remove
plug (8), to check the lubricant level occasionally
and keep the gear box two-thirds full.
The Ford Post Hole Digger is easily operated from
the tractor seat by means of the tractor hydraulic
system and the manual centering lever.
Drive the tractor into position with the auger directly
over the center of the hole location and set the engine
P.T.O. speed according to ground conditions.
CAUTION: The 1000 rpm range on
Select-O-Speed equipped tractors
should never be used to drive the
Post Hole Digger.
Make certain the hydraulic system is in Implement
Position Control. Engage the P.T.O. and lower the
digger until the auger point and cutting edges engage
the ground. In order to drill a clean hole, drill in a
foot or so then raise the auger until it is almost out
of the hole. Then, drill deeper and repeat this pro-
cess until the desired hole depth is reached.
The Ford Post Hole Digger operates equally well on
either hillside or level land. The auger unit is sus-
pended so that it is free to swing toward or away from
the tractor. The centering lever, which is easily
reached from the tractor seat, centers the auger for
vertical drilling. The adjustment provided by the
tractor lower link leveling crank compensates for the
When operating on level ground or ground of uniform
slope, drill the first hole to the desired depth and
then set the stop on the hydraulic lift control quad-
rant so the lever will be moved downward the same
distance in drilling each successive hole. On uneven
ground or slopes it will be necessary to vary the
hydraulic quadrant setting to maintain consistent
The condition and type of soil and the experience of
the operator will determine the engine rpm for the
most efficient digging. When digging hard ground,
serrated cutting edges should be used.
IMPORTANT: In the event that the auger shear bolt
(6), Figure 2, breaks due to an obstruction in digging,
replace only with special Shear Bolt, Part No. 107328.
CAUTION: Always make certain
that the P.T.O. is disengaged
before leaving the tractor seat.
Two types of Ford Augers are available, Components
22-64 through 22-69 are standard type and Components
22-72 through 22-85 are heavy duty type. Auger Com-
ponents 22-64 through 22-69 and 22-74 through 22-85
are provided with replaceable cutting edges.
