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.
!
WARNING
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.
!
WARNING
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.
!
WARNING
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.
!
WARNING
Make sure tractor/skid steer hitch is properly attached to the
equipment hitch plate. It must be secured under the hitch plate
top angle bar. Hitch locking handles must be locked down with
locking pins extending fully through bottom slots in the hitch
plate. An improperly attached hitch can allow equipment to
fall and be thrown towards bystanders and/or operator.
!
WARNING
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.
!
WARNING
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.
!
CAUTION
Never adjust tractor pressure relief valve for a pressure rating
higher than what is recommended by the tractor manufacture.
Dual-Angle Teeth
Refer to Figure 2-1 & Figure 2-2:
The Auger is shipped with teeth mounted at 40 degrees
(see Figure 2-1). If you are experiencing difficulty in
penetrating the soil, they can be turned over and
mounted at 50 degrees (see Figure 2-2) 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 20 for torque ratings.

Operating Instructions
1.
Roll tilt arms to carry the auger low to the ground
while traveling between drilling positions.
2.
Position Skid Steer/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 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 become
damaged.
4.
Maker sure auger rotation is stopped and then lower
auger point to the ground.
5.
With engine running at a slow speed, start auger
turning clockwise. Increase engine speed to desired
digging speed.

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.
IMPORTANT: Avoid side pressure on the auger.
This can damage auger and drive components.
