1
Important Safety Information
Listed below are common practices that may or may not be applicable to the products
described in this manual.
Dig Safe - Avoid
Underground Utilities
 USA: Call 811
CAN: digsafecanada.ca
Always contact your local utility
companies (electrical, telephone,
gas, water, sewer, and others)
before digging so that they may
mark the location of any
underground services in the
area.
 Be sure to ask how close you can
work to the marks they
positioned.
2
Transport Safely
 Comply with federal, state, and
local laws.
 Use towing vehicle and trailer of
adequate size and capacity. Secure
equipment towed on a trailer with
tie downs and chains.
 Sudden braking can cause a towed
trailer to swerve and upset. Reduce
speed if towed trailer is not
equipped with brakes.
 Avoid contact with any overhead
utility lines or electrically charged
conductors.
 Always drive with load on end of
loader arms low to the ground.
 Always drive straight up and down
steep inclines with heavy end of
skid steer or tractor with loader
attachment on the “uphill” side.
Tire Safety
Practice Safe Maintenance
 Tire changing can be dangerous
and must be performed by
trained personnel using the
correct tools and equipment.
 Always maintain correct tire
pressure. Do not inflate tires
above recommended pressures
shown in the Operator’s Manual.
 When inflating tires, use a clip-on
chuck and extension hose long
enough to allow you to stand to
one side and NOT in front of or
over the tire assembly. Use a
safety cage if available.
 Securely support the attachment
when changing a wheel.
 When removing and installing
wheels, use wheel handling
equipment adequate for the
weight involved.

create a hazard when driven on
public roads. They are difficult to
see, especially at night. Use the
Slow Moving Vehicle (SMV) sign
when on public roads.
 Flashing warning lights and turn
signals are recommended
whenever driving on public roads.
10/16/19
 Land Pride recommends the use
of a CAB or roll-over-protectivestructures (ROPS) and seat belt
in almost all power machines.
Combination of a CAB or ROPS
and seat belt will reduce the risk
of serious injury or death if the
power machine should be upset.
 If ROPS is in the locked-up
position, fasten seat belt snugly
and securely to help protect
against serious injury or death
from falling and machine
overturn.
 Never carry riders on the power
machine or attachment.
 Riders obstruct operator’s view
and interfere with the control of
the power machine.
 Riders can be struck by objects or
thrown from the equipment.
 Never use power machine or
attachment to lift or transport
riders.

Important Safety Information
These are common practices that may or may not be applicable to the products described in
this manual.
Avoid crystalline Silica
(quartz) Dust
Because crystalline silica is a basic
component of sand and granite,
many activities at construction sites
produce dust containing crystalline
silica. Trenching, sawing, and boring
of material containing crystalline
silica can produce dust containing
crystalline silica particles. This dust
can cause serious injury to the
lungs (silicosis).
There are guidelines which should
be followed if crystalline silica
(quartz) is present in the dust.
Handle
Chemicals Properly
 Protective clothing should be
worn.
 Handle all chemicals with care.
 Follow instructions on container
label.
 Agricultural chemicals can be
dangerous. Improper use can
seriously injure persons, animals,
plants, soil, and property.
 Inhaling smoke from any type of
chemical fire can be a serious
health hazard.
 Store or dispose of unused
chemicals as specified by the
chemical manufacturer.
 Be aware of and follow OSHA
(or other local, State, or Federal)
guidelines for exposure to airborne
crystalline silica.
 Know the work operations where
exposure to crystalline silica may
occur.
 Participate in air monitoring or
training programs offered by the
employer.
 Be aware of and use optional
equipment controls such as water
sprays, local exhaust ventilation,
and enclosed cabs with positive
pressure air conditioning if the
machine has such equipment.
Otherwise respirators shall be worn.
 Where respirators are required, wear
a respirator approved for protection
against crystalline silica containing
dust. Do not alter respirator in any
way. Workers who use tight-fitting
respirators can not have beards/
mustaches which interfere with the
respirator seal to the face.
Tractor Shutdown & Storage
 Reduce engine speed and shut-off
all power to the attachment.
 Park on solid, level ground and
lower attachment to ground or
onto support blocks.
 Put tractor in park or set park
brake, turn off engine, and remove
switch key to prevent unauthorized
starting.
 Relieve all hydraulic pressures.
 Wait for all components to stop
before leaving operator’s seat.
 Use steps, grab-handles and
anti-slip surfaces when stepping
on and off the tractor.
 Detach and store implement in an
area where children normally do
not play. Secure implement using
blocks and supports.
OFF

 If possible, change into disposable
or washable work clothes at the
work site; shower and change into
clean clothing before leaving the
work site.
 Do not eat, drink, use tobacco
products, or apply cosmetics in
areas where there is dust containing
crystalline silica.
 Store food, drink, and personal
belongings away from the work
area.
 Wash hands and face before eating,
drinking, smoking, or applying
cosmetics after leaving the exposure

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 unit.
Application
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.
Definitions
IMPORTANT: A special point of information related
to the following topic. Land Pride’s intention is this
information must be read & noted before continuing.
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.
Owner Assistance
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.
Serial Number
The HD25 series are designed to deliver up to 700 ft-lbs

! DANGER
To avoid serious injury or death:
• Hydraulic fluid under high pressure can penetrate the skin
and/or eyes causing a serious injury. 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 leaks. A doctor familiar with this
type of injury must treat the injury within a few hours or
gangrene may result. DO NOT DELAY.
• All guards and shields must be installed and in good
working condition while operating the implement.
! WARNING
To avoid serious injury or death:
Make sure hydraulic hoses are properly routed without twists
to prevent becoming stretched, pinched, or kinked. A damaged
hydraulic hose can burst and leak hydraulic fluid.
NOTE: Skid steer hydraulics can vary from one
machine to another. Be sure to review “Hydraulic
Hook-up” in your Skid Steer Operator’s Manual
before hooking hydraulic hoses to the Skid Steer.

Check Post Hole Digger Clearance
Refer to Figure 2-1 on page 25:
IMPORTANT: Cab tractors: Glass can break if
contacted by the post hole digger boom when lifting
or transporting the unit, depending on the tractor
and its three point hook-up geometry.
IMPORTANT: Hydraulic hoses can be pinched if
digger yoke (#4) comes close to the tractor’s duplex
outlet when lifting/transporting the unit, depending
on tractor and three point geometry.
IMPORTANT: Adjusting boom lift clearance and
auger digging depth may require a compromise
between limiting auger lift height and lift height
required to lift auger above a dirt mound around a
post hole. Customer should adjust lift hight to suit
while making sure the Post Hole Digger does not
cause damage to the tractor and/or tractor cab.
IMPORTANT: Digger frame may bounce up when
transporting. Make sure lift height is not set too high.

obstruct the operator’s view, interfere with controls, be
pinched by moving components, become entangled in
rotating components, struck by objects, thrown about, fall
off and be run over, etc.
Do not operate and/or travel across inclines where tractor
and/or implement can rollover. Consult your tractor’s
manual for acceptable inclines the tractor is capable of
traveling across.
Check hitch fit-up frequently. An improper fit-up to the 3point hitch, bucket mount, or loader quick hitch can cause
the post hole digger to come loose and fall.
When traveling on public roadways, travel in such a way
that faster moving vehicles may pass safely. Use accessory
lights, clean reflectors, and a slow moving vehicle sign that
is visible from the back to warn operators in other vehicles
of your presence. Always comply with all federal, state, and
local laws.
Always travel with adequate clearance between ground and
auger. Hitting an object while traveling can damage
equipment and cause operator to lose control.
Use a power machine of adequate size for the load being
carried. An undersized machine can roll over when raising
the loader arms due to high center of gravity.
Always travel with auger lowered to reduce the chances of
tip over due to high center of gravity.
Make sure safety labels are in their proper location and are
in good condition before operating the attached implement.
Read and obey all instructions on the labels.
Protect freshly dug holes immediately after digging by
filling it with a post, covering the hole with a cover capable
of supporting a person, or place a physical boundary
around the hole to stop entry into the area.
Do not use post hole digger to wrap wire or any other items.
Doing so can result in bodily injury and/or damage to the
equipment.
Use a power machine of adequate size for the load being
carried. An undersized machine can roll over when raising
the loader arms due to high center of gravity.
Do not use implement to lift objects; to pull objects such as
fence posts, stumps, etc; or to push objects. The unit is not
designed or guarded for these uses.
Never work near utilities such as gas lines, electrical lines,
or other hazards that can cause serious injury or death from
electrocution, explosion, or fire
Never make contact with underground utilities such as
electrical power lines, gas lines, phone lines, etc. They can
cause serious injury or death from electrocution, explosion,
or fire. If in doubt, call 811 (USA) before digging so that
they can mark the location of underground services in the
area. For contact information, see Dig Safe in the
“Important Safety Information” starting on page 1.

When traveling on public roadways, travel in such a way
that faster moving vehicles may pass safely. Use accessory
lights, clean reflectors, and a slow moving vehicle sign that
is visible from the back to warn operators in other vehicles
of your presence. Always comply with all federal, state, and
local laws.
1. Select a safe ground travel speed when transporting
from one area to another.
2. Transport Post Hole Digger low to the ground to
maintain stability but at a height that does not block
your view:
• Skid/Loader Plate Mount: Transport with
cylinders on end of loader arms fully retracted,
motor/gearbox housing supported in the rest
support, and auger low to the ground at a height
that does not block your view.
• Bucket Mount: Transport with auger hanging
straight down and low to the ground at a height that
does not block your view.
3. Always travel straight up and straight down inclines.
Make turns only on level ground.
4. Enter ditches and inclines slowly to make sure the
auger does not dig into the ground. Stop and raise
auger if needed to cross a ditch or start up an incline.
5. Reduce skid steer ground speed when turning.
Leave enough room to clear obstacles such as
buildings, trees, and fences.
6. Keep away from electrical power lines. Place an
orange warning sign under overhead power lines
indicating type of danger above.
7. When traveling on roadways, transport in such a way
that faster moving vehicles may pass you safely.
8. Reduce transport speed when traveling over rough
or hilly terrain.
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 a
damaged implement.
4. Maker sure auger rotation is stopped and then lower
auger point to the ground.
28
HD25 and HD35 Hydraulic Post Hole Diggers 317-076M
5. With engine running at a slow speed, start auger
turning clockwise. Increase engine speed to desired
digging speed.
IMPORTANT: Avoid moving or causing side
pressure on the auger while in the ground. This can
damage the 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 1 to
2 feet before it is out of the hole. This will keep the
auger from wobbling with an unbalanced dirt load.
IMPORTANT: If auger stalls while digging, raise
auger to free it. Continue normal digging operations
by lowering the auger slowly into the hole.
IMPORTANT: If auger starts to screw itself into the
soil, stop auger rotation immediately and raise auger
to free it. Continue normal digging operations by
lowering the auger slowly into the hole.
IMPORTANT: If the dirt auger bit can not penetrate
an obstruction, change auger head to the optional
rock auger head, switch auger bit to the optional rock
auger bit, or dig a new hole nearby. See “Options &
Accessory” Section in this manual for optional rock
auger heads and rock auger bits.
IMPORTANT: Do not reverse auger rotation when
raising it up. This will dump soil back into the hole.
IMPORTANT: Some tractors have a hydraulic relief
valve to protect the equipment. This valve will open
in a stalled situation and allow oil to bypass. Check
your tractor Operator’s Manual to see if it is
equipped with a relief valve.
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.
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 to an acceptable height before
transporting. Be careful to watch out for people,
obstructions, and uneven terrain.

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.
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 44 and
“Features & Benefits” on page 47 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 44 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.
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.

HD25/35 3-Point Down Pressure Kit
Refer to Figure 4-8:
Land Pride offers a Down Pressure Kit for 3-point Post
Hole Diggers to provide additional digging force in hard
soil by use of a hydraulic cylinder (#1) to press down on
the boom. The down pressure created is between 300
and 500 lbs depending on mounting configuration.
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
To avoid serious injury or death:
Relieve all hydraulic pressure before disconnecting any lines
or pipes between implement and tractor hydraulic system.
! WARNING
To avoid serious injury or death:
• Hydraulic fluid under high pressure can penetrate the skin
and/or eyes causing a serious injury. 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 leaks. A doctor familiar with this
type of injury must treat the injury within a few hours or
gangrene may result. DO NOT DELAY.
• Always follow “Tractor Shutdown Procedure” provided in
this manual before dismounting the tractor.
The down pressure kit is ready for operating after it has
been properly installed on the Post Hole Digger (see
following pages for Assembly Instructions). This kit
should be used only on hard soils where the auger will
not penetrate the ground on its own.
Normal digging operations are made with remote control
lever for the down pressure cylinder in neutral position.
When encountering hard soil, move control lever in the
proper direction to apply pressure. When lever is held in
this position, hydraulic pressure will not exceed 1500 psi.
Return control lever to neutral to continue normal digging
operations.

General Maintenance Information
Daily Inspections
Proper servicing and adjustments are key to the long life
of any implement. With careful inspection and routine
maintenance, you can avoid costly downtime and repair.
1.
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 affect its performance.
Safety Information
! DANGER
2.
3.
4.
5.
Check all bolts after using the unit for several hours to
be sure they are tight.
After each use, inspect auger for loose, worn, or
damaged auger teeth, tip, flighting, and gearbox
output shaft bolts and nuts.
Keep cutting edges sharp. Sharp cutting edges dig
easier and better.
Check gearbox fluid level periodically. Refer to “Gear
Lube Fluid Level” on page 42 for detailed
instructions.
Replace any worn, damaged, or illegible safety
labels by obtaining new labels from your Land Pride
dealer.
To avoid serious injury or death:
• All guards and shields must be installed and in good
working condition while operating the implement.
• Keep all persons away from the rotating auger. A person
can become entangled or pinched in the unit.
• Always secure equipment with solid, non-concrete supports
before working under it. Never go under equipment
supported by concrete blocks or hydraulics. Concrete can
break, hydraulic lines can burst, and/or hydraulic controls
can be actuated even when power to hydraulics is off.
! WARNING
To avoid serious injury or death:
• Allow only persons to perform maintenance on this
implement who have been properly trained in its safe
operation.
• Always shut power machine down following the “Shutdown
Procedure” provided in this manual before leaving the
operator’s seat.
• Make sure safety labels are in their proper location and are
in good condition before operating the attached implement.
Read and obey all instructions on the labels.
• Perform scheduled maintenance. Check for loose
hardware, missing parts, broken parts, structural cracks,
and excessive wear. Make repairs before putting implement
back into service.
• Do not alter implement or replace parts on the implement
with other brands. Other brands may not fit properly or
meet OEM (Original Equipment Manufacturer)
specifications. They can weaken the integrity and impair the
safety, function, performance, and life of the implement.
Replace parts only with genuine OEM parts.

Long-Term Storage
Ordering Replacement Parts
Clean, inspect, service, and make necessary repairs to
the digger when storing it for long periods and when
storing it at the end of a working season. This will help
ensure the digger is ready for field use the next time you
hook-up to it.
Land Pride offers equipment in factory standard beige
with black highlights. Equipment may also be purchased
in orange. Special attention must be given to the part
number to prevent ordering the wrong color. A suffix
number corresponding to one of the colors below must be
added at the end of the part number. Parts ordered
without the suffix number will be supplied in factory
standard colors.
1.
Remove any dirt and grease that may have
accumulated on the digger and moving parts. Scrape
off compacted dirt and wash surface thoroughly with a
garden hose. A coating of oil may also be applied to
the lower auger to minimize oxidation.
2. Check auger teeth and bolts for wear and replace if
necessary. See “Dual-Angle Teeth” on page 27.
3. Inspect for loose, damaged, broken or worn parts
and adjust or replace as needed.
4. Repaint parts where paint is worn or scratched to
prevent rust. Ask your Land Pride dealer for aerosol
touch-up paint. Paint is also available in touch-up
bottles with brush, quarts, and gallon sizes by adding
TU, QT, or GL to the end of the aerosol part number.
82 . . . . . . . Orange
85 . . . . . . . Black
For example, if you are ordering a replacement part with
part number 555-555C and the existing part is orange,
then add the suffix 82 to the end of the number to make
the part number read 555-555C82.
