landscapers, contractors, construction companies,
farmers, ranchers, and municipalities. No matter what
your post hole digging needs are, Land Pride has a model
to meet those needs.
NOTE: A special point of information that the
operator should be aware of before continuing.
Owner Assistance
The Online Warranty Registration should be completed
by the dealer at the time of purchase. This information is
necessary to provide you with quality customer service.
The parts on your Post Hole Digger have been specially
designed by Land Pride and should only be replaced with
genuine Land Pride parts. Contact a Land Pride dealer if
customer service or repair parts are required. Your Land
Pride dealer has trained personnel, repair parts, and
equipment needed to service the implement.

WARNING
!
CAUTION
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.
Always secure attached implement with solid supports before
working under it. Never work under equipment supported by
hydraulics. Hydraulics can drop equipment if controls are
actuated or if hydraulic lines burst. Either situation can drop
machinery instantly even when power to hydraulics is off.
WARNING
Never adjust tractor pressure relief valve for a pressure rating
higher than what is recommended by the tractor manufacture.
WARNING
Protect holes not filled immediately after digging with a cover
over the hole capable of supporting a person or by placing a
physical boundary around the hole to stop entry into the area.
!
WARNING
Do not use Post Hole Digger to wrap wire or any other items.
Doing so can result in bodily injury and/or damage to
equipment.
!
WARNING
!
WARNING
!
WARNING
!
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.
!
!
CAUTION
CAUTION
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.
Do not install a bolt that is longer than what was originally
supplied with the auger. A protruding fastener is more likely to
grab loose clothing and may cause serious injury or death.
Make sure skid/loader plate is properly attached to the Post
Hole Digger. The skid/loader plate must be secured under the
auger hitch top angle bar. Lock pins must extend fully through
bottom slots in the auger hitch in the locked down position. An
improperly attached hitch can allow equipment to fall and/or
be thrown towards bystanders and/or operator.
The tractor/skid steer hydraulics must not to exceed 3500 PSI.
The attached hydraulic operated equipment is rated for a
maximum of 3500 PSI working pressure. Exceeding maximum
PSI can result in serious injury, death, or equipment damage.

Section 2: Operating Procedures
Operating Instructions
1.
Rotate top of tilt arms back to carry auger low to the
ground while traveling between drilling positions.
2. Position skid steer/tractor on the upside of hill when
drilling a hole. This will greatly improve balance and
down force.
3. Experiment with auger speeds before digging.
Increase skid steer/tractor engine speed to increase
auger speed and decrease engine speed to reduce
auger speed. Run at higher auger speeds when
digging in soft and/or sandy soils and at lower auger
speeds when digging in hard, rocky, or frozen soils.
Normal auger speed is 85 to 100 rpm. Never exceed
110 rpm or the equipment can be damaged.
IMPORTANT: Operate one loader function at a time.
Operating two or more functions at a time (loader
arms, tilt arms, engine speed, and loader
positioning) can lead to damaged equipment.
Refer to Figure 2-3:
IMPORTANT: Before digging, rotate auger 
hitch (#3) horizontal as shown in Figure 2-3. This will
put distance between motor/gearbox housing (#1)
and support rest (#2). The auger, when first entering
soil, could hit a solid object causing auger to swing
around and damage equipment. Care should always
be taken when first starting to drill a hole.
4. Extend hydraulic cylinders on end of skid steer/
tractor loader arms until auger hitch (#3) is horizontal
as shown.
5. Maker sure auger rotation is stopped and then lower
auger point to the ground.
IMPORTANT: Avoid side pressure on the auger. This
can damage auger and drive components.
7.
Periodically adjust machine’s position to keep auger
vertical while drilling. Be careful not to damage
gearbox or auger. Refer to “Adjust Post Hole Digger
Vertically” on page 20.
8. Apply down pressure to assist ground penetration.
Excessive down pressure can stall auger. If auger
speed slows or stops, reduce down pressure.
!
CAUTION
Always stop auger rotation before raising unit out of the hole
and when hitting a solid object. An auger that wobbles out of
the hole can swing erratically causing injury to operator 
and/or damage to equipment.
NOTE: Do not reverse auger rotation when raising
it up. This will dump soil back into 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.
IMPORTANT: Stop auger rotation immediately if it
becomes stalled while digging. Some power
machinery have a hydraulic relief valve to protect
equipment. This valve will open in a stalled situation
and allow oil to bypass the machine’s hydraulic
motor. Check your Operator’s Manual to see if your
machine is equipped with a hydraulic relief valve.
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.
Keep motor/gearbox
housing (#1) away
from support rest (#
while auger is opera

Vertical Indicator
Figure 2-4
Adjust Post Hole Digger Vertically
Refer to Figure 2-4:
The patent pending vertical indicator arrow (#1), when in
view of the operator, helps operator to verify that the Post
Hole Digger is operating vertical from front to back.
1.
Stop skid steer/tractor on a surface that is level side
to side.
2. Lower loader arms until auger point is resting on the
ground at the location the hole is to be drilled.
IMPORTANT: Be careful not to move forward or
backward while digging except to keep auger
vertical. Damage to auger and/or hitch can occur.
3. Ease skid steer/tractor forward or rearward and/or
extend or retract hydraulic cylinders on the end of the
skid steer/tractor loader arms until vertical indicator
arrow (#1) point is on the “Vertical Line” as shown.
4. To keep auger vertical while digging, repeat
adjustments outlined in step 3 above as needed.
General Operation
By now you should have thoroughly read your Operator’s
Manual, properly attached your Post Hole Digger to your
machine, verified auger rotation turns clockwise, and
gone over the “Operating Checklist” on page 16. Make
sure your operator protective shield or safety door is
securely in place. If you plan to dig holes immediately,
you should have 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 SA20 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 keep auger from falling off its support rest
causing damage. 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.
20 Model SA20 Hydraulic Post Hole Diggers 317-215M
Once you have safely arrived at your digging site,
position your skid steer/tractor so that the auger is
directly over the spot where you want to dig a hole.
Extend hydraulic cylinders on end of skid steer/tractor
loader arms to rotate auger hitch horizontal as shown in
Figure 2-3 on page 19. Lower skid steer/tractor arms and
auger until auger point is on the ground where the hole is
to be dug. If needed, adjust skid steer/tractor position
forward or rearward to align auger vertically.
Do not operate Post Hole Digger with auger more than 
2" or 3" above ground. The auger could swing erratically
causing injury to operator and damage to equipment.
With engine at idle, engage hydraulic drive circuit and
raise engine rpm to operate Post Hole Digger at its rated
hydraulic flow. Auger should be turning clockwise at an
approximate speed of 85 to 100 rpm. Do not operate
auger above 110 rpm or damage to the Post Hole Digger
and skid steer/tractor could result. Use loader arm
controls to lower auger into the ground. After penetrating
the ground approximately 24", stop auger rotation and
raise auger up to remove soil and debris from the hole.
Lower auger back down and 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 auger back down to continue digging.
Repeat this procedure until hole is at its final depth. Allow
auger to turn several more 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.
Periodically adjust skid steer/tractor position to keep
auger vertical while digging the hole. Use vertical
indicator as a guide. Be careful not to damage gearbox or
auger.
Apply down pressure to assist ground penetration. If
auger speed slows or stops, reduce down pressure.
Excessive down pressure can stall auger. Stop auger
rotation immediately if an obstacle is encountered that
stalls the auger while digging. Reverse auger rotation
and lift up to clear the obstacle.
Once hole is completed, disengage hydraulic drive, raise
auger to a point where the auger tip is approximately 12"
off of the ground, release park brake and move away from
the hole.
Before dismounting your skid steer/tractor; you must
always set park brake, lower your loaders arms and
attachment to the ground, turn off machine, and remove
ignition key. If you must park on a hillside you should
always chock skid steer/tractor wheels for an extra
measure of safety.
With a little practice and experience you should become
very good at operating your Land Pride SA20 Series Post
Hole Digger.
