Introduction
Introduction
Land Pride welcomes you to the growing family of new
product owners.
This Post Hole Digger has been designed with care and
built by skilled workers using quality materials. Proper
assembly, maintenance, and safe operating practices will
help you get years of satisfactory use from this machine.
Application
Land Pride offers a complete line of post hole diggers
designed to meet a wide range of customer needs and
applications. Our HD25 and HD35 series post hole
diggers are hydraulically driven and accommodate
augers ranging from 6" to 24" in diameter. They can be
purchased with a bolt-on mount for mounting to the side
of a bucket on a tractor front-end loader, with a boom for
mounting to a cat. I or II 3-point hitch, or skid/loader
mount for attaching to a skid steer or to a tractor front-end
loader with a front loader hitch mount. The HD25 series
requires a hydraulic flow system capable of producing 5
to 12 GPM and the HD35 series requires a hydraulic
system capable of producing 10 to 25 GPM.
The digging performance of the bucket mounted and
universal quick hitch mounted Post Hole Diggers can be
improved in heavy hardened soil conditions by applying
additional down pressure with the front-end loader. An
optional hydraulic down pressure kit is available to
improve the performance of the 3-point boom mounted
Post Hole Diggers. The ability to reverse the auger on
hydraulic Post Hole Diggers greatly reduces the strain on
the auger and skid steer or tractor when extracting the
digger from the ground.
The HD25 series are designed to deliver up to 700 ft-lbs
of torque to meet the heavy duty needs of nurseries,
landscapers, contractors, construction companies,
farmers, ranchers, and municipalities. The HD35 series
will deliver up to 1,605 ft-lbs of torque when industrial
duty is preferred.
Terminology
“Right” or “Left” as used in this manual is determined by
facing forward in the direction the machine will operate
while in use unless otherwise stated.

condition before operating the digger.
Use a skid steer or tractor of adequate size. A skid steer or
tractor that is too small can tip over when loader arms are
raised due to high center of gravity.
Use the Post Hole Digger for its intended purpose only. Do not
use digger to lift or carry objects; to pull fence posts, stumps,
or other objects; or to tow other equipment. Doing so can
damage the unit, cause serious bodily injury, or death.
Do not operate auger over 110 rpm or damage to the Post
Hole Digger could result.
!
CAUTION!
Never adjust tractor pressure relief valve for a pressure rating
higher than what is recommended by the tractor manufacture.
Always travel with adequate clearance between ground and
auger. Hitting an object while traveling forward can damage
the auger, machine, and injure the operator.
Use a skid steer or tractor of adequate size. A skid steer or
tractor that is too small can tip over when loader arms are
raised due to high center of gravity.
Always travel with auger lowered to reduce the chances of tip
over due to high center of gravity. Tether auger with a chain if
necessary to stop it from swinging while transporting.
Avoid tipping the tractor/skid steer over. Never operate on hill
sides or sloping ground that will tip the machine over. Make
sure the machine is always on firm stable ground.
Before digging, contact your local utility companies
(electrical, telephone, gas, water, sewer, and others) so that
they may mark the location of any under ground services in the
area. Be sure to ask how close you can work to the marks they
positioned. Avoid contact with any over head utility lines or
electrically charged conductors.

Section 3: Operating Instructions
Dual-Angle Teeth
Refer to Figure 3-1 & Figure 3-2:
The Auger is shipped with teeth mounted at 40 degrees
(see Figure 3-1). If you are experiencing difficulty in
penetrating the soil, they can be turned over and
mounted at 50 degrees (see Figure 3-2) for a more
aggressive bite. Be sure to tighten all mounting hardware
to the proper torque when securing teeth to the Auger.
See “Torque Values Chart for Common Bolt Sizes” on
page 38 for torque ratings.
5. 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.
6. Periodically adjust the machine’s position to keep the
auger and hole vertical. Be careful not to damage
gearbox or auger.
7.
If possible, apply down pressure to assist penetration
into the ground. 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.
Do not reverse auger rotation when raising it up. This
will dump soil back into the hole.

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 lower speeds when digging in hard, rocky
or frozen soils. Normal auger speed is 85 to 100 rpm.
Never exceed an auger speed of 110 rpm or the
equipment can become damaged.
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.
8. 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.
9. 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.
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.
It is best to leave drilling through hard rock to
premium high pressure drilling equipment or other
rock excavation methods
IMPORTANT: Some tractors have a hydraulic relief
valve to protect equipment. This valve will open in a
stalled situation and allow oil to bypass the hydraulic
motor. Check your Operator’s Manual to see if your
machine is equipped with a hydraulic relief valve.
10. If connected to a front loader, roll tilt arms into a low
carry position; and if connected to a 3-point hitch,
raise auger fully up before transporting from one
digging site to the next. Be careful to watch out for
people, obstructions, and uneven terrain.
4. Maker sure auger rotation is stopped and then lower
auger point to the ground.

Section 3: Operating Instructions
General Operation
By now you should have thoroughly read your Operator’s
Manual, properly installed your Post Hole Digger onto
your machine and performed your pre-start and
operational running checklist. If you plan to dig holes
immediately, you should have also contacted your local
utility companies to make sure it is safe to dig where you
plan to work. If you haven’t done all of the things just
described above, please stop and do them now. This is a
must for your safety and the safety of others.
Now that you are properly briefed, your Post Hole Digger
is properly installed, and you have the proper digging
authorization from the utility companies, it’s time to
transport to the work site. Make sure that the Post Hole
Digger is in the raised position and not in contact with the
ground. If you have an extensive distance to travel, you
may want to secure the auger with ropes, slings, or
chains to prevent swinging and damage during transport.
Select a safe speed and transport to your digging site in
such a manor that faster moving vehicles can pass you
safely. A slow moving vehicle sign should be employed if
you are using a public road or right-of-way.
If an obstacle is encountered that stalls the auger,
reverse auger rotation and lift up to clear the obstacle.
Periodically adjust the machine’s position to keep the
auger and hole vertical. Be careful not to damage
gearbox or auger.
Before dismounting your tractor; you must always set the
park brake, lower Auger to the ground, turn off the
machine, and remove the ignition key. If you must park on
a hillside, you should always chock the tractor wheels for
an extra measure of safety.
With a little practice and experience you should become
very good at operating your Land Pride HD25 or HD35
Series Post Hole Digger.
See “Specifications & Capacities” on page 32 and
“Features & Benefits” on page 35 for additional
information on performance enhancing options.
Once you have safely arrived at your digging site,
position your tractor so that the auger is directly over the
spot where you want to dig a hole. Make sure your
operator protective shield or safety door is securely in
place. Lower auger to a point where the auger clears the
ground by approximately 12". Do not operate the digger
when the auger is more than 12" above ground level or
the auger could bind or swing erratically causing injury to
the operator and damage to the equipment.
With the engine at idle, engage hydraulic circuit and raise
engine RPM to operate at the recommended hydraulic
flow to a point where the auger is turning at a speed of
approximately 85 to 100 RPM. (Refer to “Gallons per
minute rating” on page 32 for recommended hydraulic
flow) Do not operate the auger at speeds over 110 RPM
or damage to the Post Hole Digger and skid steer/tractor
could result. Using the controls, lower the auger into the
ground until the desired depth is achieved and then raise
the spinning auger back up to remove extraneous soil.
Once the hole is completed, disengage hydraulic drive
circuit, raise auger to a point where the auger tip is
approximately 12" off of the ground, release the park
brake, and move away from the hole.
