Operating Instructions
1. Carry the auger low to the ground while traveling
between drilling positions.
2. Position tractor on the upside of the hill when drilling
a hole. This will greatly improve its balance and down
force.
3. Experiment with auger speeds before digging.
Increase engine speed to increase auger speed and
decrease engine speed to reduce auger speed. Run
at higher speeds when digging in soft and/or sandy
soils and at lower speeds when digging in hard,
rocky, or frozen soils. Never exceed an auger speed
of 300 RPM or the equipment can become damaged.

Section 3: Operating Instructions
IMPORTANT: Operate one function at a time.
Operating two or more functions at a time (lift arms,
engine speed, and positioning) can lead to damaged
equipment.
5. Maker sure auger rotation is stopped and then lower
auger point to the ground.
6. With engine running at a slow speed, start auger
turning clockwise. Increase engine speed to desired
digging speed.
IMPORTANT: Avoid side pressure on the auger.
This can damage auger and drive components.
7. Periodically adjust the machine’s position to keep the
auger and hole vertical. Be careful not to damage
gearbox or auger.
8. If Down Pressure Kit is installed, apply down
pressure to assist ground penetration. If auger speed
slows or stops, back off down pressure. Excessive
down pressure can stall the auger.
IMPORTANT: Always stop auger from rotating
before raising it out of the hole. This will keep auger
from wobbling with an unbalanced dirt load.
General Operation
By now you should have thoroughly read the Operator’s
Manual, properly installed the Post Hole Digger onto a
tractor, and performed a pre-start and operational
running checklist. Before digging, contact the local utility
companies to make sure that the planned digging site is
safe and free of underground lines. If all of the above has
not been done, please stop and do them now. This is a
must for your safety and safety of others.
Make sure that the Post Hole Digger is in the raised
position and not in contact with the ground before
transporting to the work site. You may want to secure the
auger with ropes, slings, or chains if you have an
extensive distance to travel to prevent swinging and
potential damage in transport. Transport to your digging
site at a safe speed and in such a manner that faster
moving vehicles may pass safely. A slow moving vehicle
sign should always be properly displayed when using a
public road or right-of-way.
Once you have safely arrived at your digging site,
position tractor with auger directly over the spot you want
to dig a hole. Lock tractor brakes to prevent rolling while
digging.
Do not reverse auger rotation when raising it up. This
will dump soil back into the hole.
NOTE: Damage to the gearbox or auger can result if
the tractor moves while the auger is in the hole.
9. After penetrating the ground approximately 24", stop
auger rotation and raise it up to remove soil and
debris from the hole. Lower auger back down to
continue digging. Dig another 24" and again raise
auger up except this time keep auger turning to
lessen the strain on the equipment. Stop raising
auger within 1 to 2 feet of being out of the hole and
lower it back down to continue digging. Repeat this
procedure until hole is at its final depth.
10. Allow auger to turn several revolutions at final depth.
With auger still turning, raise auger up to within
1 to 2 feet of being out of the hole. Stop auger
rotation and continue to raise auger out of the hole.
Lower the tractor’s three-point hitch to a point where the
auger clears the ground by approximately 12" and set the
three-point height limit to this position.
IMPORTANT: Stop auger immediately if auger starts
to screw itself into the soil, hits a large obstruction or
becomes stalled, raise auger up to free it and then
continue normal digging operations by lowering
auger down slowly. If auger does not penetrate
obstruction, raise auger out of the hole and remove
obstruction by other means or dig a new hole
nearby.
Before dismounting tractor you must always set park
brake, lower the three-point attachment to the ground,
turn off tractor, and remove ignition key. Always chock
tractor wheels for an extra measure of safety if you must
park on a hillside. With a little practice and experience
you should become very good at operating your Land
Pride Post Hole Digger.
It is best to leave drilling through hard rock to
premium high pressure drilling equipment or other
rock excavation methods
With tractor engine at idle, engage PTO, and raise PTO
speed to 300 rpm. Using the tractor’s three-point control
lever, lower auger into the ground until desired depth is
achieved and then raise spinning auger back up to
remove loosened soil.
Use an optional alignment handle or a down-pressure kit
to make these tasks safer and easier.
Once the hole is completed, disengage PTO, raise auger
to a safe height, release park brake, and pull ahead with
tractor.
See “Specifications & Capacities” on page 31 and
“Features & Benefits” on page 33 for additional

Down Pressure Kits
Refer to Refer to Figure 4-1:
Land Pride offers augers in a variety of sizes to best suit
a wide variety of applications; 6", 9", 12", 14" 18", and 24"
diameter.
Refer to Figure 4-3:
The Down Pressure Kit allows for additional digging force
in hard soil by use of a hydraulic cylinder to press down
on the boom. Down pressure created is between 300 and
500 lbs. depending on mounting configuration.
Contact your Land Pride dealer for the auger that best
suits your application.
See Section 1, “Assembly & Set-up“, for proper
installation.
IMPORTANT: Not providing some form of down
pressure relief to the hydraulic system can damage
the Post Hole Digger and tractor when raising auger.
IMPORTANT: The “Down Pressure” relief valve is
factory set to 1500 psi and must not be changed.
Exceeding this pressure can damage equipment.

DANGER
Hydraulic fluid under high pressure can penetrate skin. Wear
protective gloves and safety glasses or goggles when working
with hydraulic systems. Use a piece of cardboard or wood
rather than hands when searching for hydraulic leaks. If
hydraulic fluid is injected into the skin or eyes, it must be
treated by a doctor familiar with this type of injury within a
few hours or gangrene may result. DO NOT DELAY.
!
WARNING
Be sure to relieve all hydraulic pressure before disconnecting
any lines or pipes between the Post Hole Digger and the
tractor hydraulic system.

Section 5: Maintenance & Lubrication
General
Proper servicing and adjustment is the key to the long life
of any implement. With careful inspection and routine
maintenance, you can avoid costly down time and repair.
Check all bolts after using the unit for several hours to be
sure they are tight. Replace any worn, damaged, or
illegible safety labels by obtaining new labels from your
Land Pride Dealer.
The parts on your Post Hole Digger have been specially
designed and should only be replaced with genuine
Land Pride parts. Do not alter the digger in a way which
will adversely affects its performance.
!
DANGER
Do not allow anyone to perform maintenance on this
implement who has not been properly trained in its safe
operation.
!
DANGER
Always disengage PTO, engage parking brake, shut tractor
engine off, remove switch key, and wait for all moving parts to
come to a complete stop before servicing, adjusting, cleaning
and/or maintaining this machine. Also, disconnect driveline
from tractor PTO before servicing driveline. The PTO can be
engaged if tractor is started causing serious injury or death.
!
DANGER
All guards and shields must be installed and in good working
condition at all times while operating the digger. Do not
operate digger with missing shields.
!
DANGER
Keep all persons away from rotating driveline and auger.
Contact with rotating parts may cause serious injury or death.
!
DANGER
!
CAUTION
Do not alter Land Pride equipment or replace parts with other
brands. Doing so can cause equipment to perform improperly
and may lead to breakage that can cause bodily injury.
Replace parts only with genuine Land Pride parts.
1. Check all bolts after using unit for several hours to be
sure they are tight.
2. After each use, inspect auger for loose, worn, or
damaged auger teeth, tip, flighting, and gearbox
output shaft bolts and nuts.
3. Keep cutting edges sharp. Sharp cutting edges dig
easier and better.
IMPORTANT: Drivelines require a retainer screw to
prevent the driveline yoke from coming off the
gearbox shaft soon after the shearbolt has sheared.
IMPORTANT: Maintain driveline shearbolt at all
times. A bent or damaged shearbolt can result in
severe damage to the Post Hole Digger.
4. Replace the shearbolt if it is bent, damaged, or
sheared with the following bolt:
• PD10 drivelines without a clutch:
M8 x 1.25 grade 8.8 shearbolt
• PD15, PD25, & PD35 drivelines without a clutch
3/8"-16 grade 5 shearbolt.
• PD25 & PD35 drivelines with a clutch:
3/8"-16 grade 5 shearbolt
5. Always maintain driveline u-joints and profiles with
lubrication. See “Lubrication Points” on page 29.
6. Check gearbox fluid level periodically. If fluid is
required, refer to “Lubrication Points” on page 29.
7. Replace any worn, damaged, or illegible safety
labels by obtaining new labels from your Land Pride
dealer.
Always secure Post Hole Digger in the raised position with
solid supports before servicing underside of auger. Never
work under equipment supported by hydraulics. Hydraulics
can drop equipment instantly if controls are actuated even
when power to the hydraulics is shut off.
!
WARNING
Read and obey all instructions on the safety labels. Make sure
they are installed in their proper location and are in good
condition before operating the digger.
!
WARNING
Frequently check all hardware to make certain it is tight.
Operating equipment with loose pins, bolts, and nuts can
cause equipment to not perform properly and may result in a
serious breakdown that can cause bodily injury or death.
