Attaching the PTO shaft:
Before installing the PTO shaft make sure that the RPM rating and the direction of rotation match those of the
tractor. Carefully read the PTO shaft and tractor instructions. Before operation, make sure that the guards are
installed on the power take off of the tractor and PTO shaft. Make sure that they cover the PTO shaft through-
out its length. Note: The PTO shaft may be too long and require shortening. See “Shortening a PTO
driveline” below.
Press the locking pin on the PTO yoke and slide yoke on to the PTO of the tractor until the pin seats. Pull on
PTO shaft to make certain it is locked in place. Repeat the procedure for the machine end. Attach the PTO
cover’s safety chains to a stationary part of the tractor. Leave some slack in the chain to accommodate move-
ment.
Shortening a PTO driveline:
1. With the machine attached to the tractor’s
3-point hitch, and the PTO shaft not in-
stalled, separate the PTO shaft. Attach the
machine end to the machine and the other
end to the tractor PTO input shaft.
2. Raise the machine by using the tractor’s
hydraulic 3-point hitch to its maximum
lift height.
3. Hold the half shafts next to each other and
mark them so each end is approximately
1/2” from hitting the end of the telescopic
profiles.
4. Shorten the inner and outer guard tubes
equally.
5. Shorten the inner and outer profiles by the
same length as the guard tubes. Using a
rattail file, round off all sharp edges and
burrs. Grease the telescopic profile gener-
ously before reassembling.
When fully extended, the tubes must overlap by at least 1/3 of the length of the pipes
(LT). When retracted, the min. acceptable clearance is 1-2 cm (3/8”-3/4”)

Operating the Post Hole Digger:
• Warning: The auger point should be raised no higher than 12” above the ground when engaging the PTO,
(Fig. 2).
• The auger must be vertical to the ground, (Fig. 3). Adjust to the lift arm as necessary to place the auger in a
vertical position to the ground. Do not engage the PTO at this time. With the auger point off the ground,
slowly lower it until the auger point is touching the ground. If the auger is not vertical, move the tractor
forward or backward to get in the proper working position.
• Set the tractor brakes and take tractor out of gear.
• Lower the auger to the ground. With the tractor engine in idle, slowly engage the PTO.
• Increase the speed as required to move dirt out of the hole.
• Do not exceed 540 rpms! Operate at or below 540 rpms. Higher speeds can cause equipment failure and
serious injury or death.
• Depending on the soil conditions, it may be necessary to hold the hydraulic controls in position to assist
digging.
• Never allow anyone to use their body weight to press the auger into the ground.
• Before each use, check the condition of the cutting edges and auger point. If the auger is having trouble
penetrating the ground, it may be time to replace the cutting edges and point.
• Once the auger digs down approximately 12”, raise the auger to clear the dirt from the hole. Do not raise
the auger completely out of the hole. Once the dirt is cleared, lower auger and repeat the process until the
predetermined depth is achieved.
Danger: Never allow anyone to stand close to the auger and driveline when
operating. Serious injury or death can occur.

their use.
• liability
for injury or warranty.
• Check the tightness of all hardware on the Post hole digger on a regular basis.
• Check the gear box for proper amount of oil.
Shear Protection:
The 5/16”x2-1/2” Hex Bolt connecting the PTO shaft to the gearbox is a shear bolt. If the auger encounters a
hard object, such as large rocks or concrete, the auger could lock up and stop rotation. The auger bolt is
designed to shear off to prevent damage to auger or gearbox.
In the event the auger bolt shears, check the auger and gearbox for damage. Replace damaged parts with OEM
parts only!
DANGER: Stop engine, lock parking brake and remove key before performing any
service or maintenance.
Never rely on the tractor lift system. Place blocks or stands under the Post Hole Digger to
prevent it from falling, causing serious injury or death.
Always use personal protection devices, such as glasses or gloves when performing mainte-
nance on the Post Hole Digger.
Warning: Never replace the shear bolt with a bolt harder than a GRADE 2 bolt. This can
damage the implement and void the warranty. It is advisable to replace the shear bolt with
an OEM shear bolt. Contact your dealer for the correct replacement bolt.
