2. Repeat the procedure to the other driveline half.
Remove all burrs and cuttings.
3. Apply multi-purpose grease to inside of outer (female)
driveline section. Assemble driveline and install on
tractor and digger. Pull on each driveline section to be
sure yokes lock into place. Make certain driveline
shielding is in place and in good condition.
4. Carefully raise and lower the digger and check to be
sure the PTO assembly does not jam. If it does, cut
equal amounts from each half of the PTO assembly.
5. Check the swinging drawbar of the tractor and make
sure the PTO driveline assembly will not contact. The
swinging drawbar can be moved forward on some
tractors or it can be removed.
INSTRUCTIONS (continued)
Operate the post hole digger only on a tractor with
540 RPM PTO shaft. The tractor’s engine speed
should not exceed 1200 RPM while digging.
On some tractors it may be necessary to remove
the drawbar or slide it to one side. This will prevent
the PTO driveline shaft from coming in contact with
the drawbar. See your tractor’s operator’s manual for
details.
CAUTION!
If you have ANY questions, regarding the proper
operation of this digger, contact your dealer or the
manufacturer.
WARNING!
When attaching PTO yoke to tractor PTO shaft, it is
important that spring-activated locking pin or balls
operate freely and are seated in groove on PTO shaft.
A loose shaft could slip off and result in personal
injury or damage to equipment.
GEARBOX OIL FILL
NOTE: The gearbox is shipped WITHOUT lubricant, so it
will be necessary to fill is before use. With the gearbox in
a level position, fill to the side inspection hole with a good
90 wt. gear lubricant. Gearbox holds 56 fluid oz. Check
often and add lubricant if necessary.
OPERATING INSTRUCTIONS
PRE-OPERATION CHECKLIST
This Post Hole Digger was designed for one-man
operation from the tractor seat. It is the responsibility
of the operator to see that no one else is within
twenty-five feet (25’) of the digger when it is
operating.
• Set tractor brakes. Take tractor out of gear. Shift to
“Park” (if applicable).
• Do not allow anyone to stand behind, or to the side of
a rotating auger.
• Lower auger point slowly to the ground with the PTO
disengaged.
• With the auger point lowered to the ground, set the
engine speed to idle, then engage the PTO. Make
sure the auger point is on the ground before engag-
ing the PTO.
• Increase the speed as required so dirt is conveyed
from the hole. Refer to Owner’s Manual for sugges-
tions on PTO speed.
• Under no circumstances should the PTO be run in
excess of 540 RPM.
OPERATION
• In some types of soil, it may be necessary to hold back
against the auger screw suction by moving the
hydraulic control lever to “HOLD” or “RAISE” position
to keep the auger from screwing into the ground.
• NEVER use body weight to help the auger
penetrate the ground. When the ground is too
tough to penetrate with your cutting edges and point,
sharpen or replace them and try again. These are
replaceable parts and must be in good condition to
penetrate. (Optional Hydraulic Downpressure Kit is
available – order #170810.)
• If you have difficulty penetrating hard ground, refer to
Owner’s Manual Trouble-shooting section for
suggestions.
• When the auger has been lowered about a foot or so
into the ground, raise the auger almost out of the hole
to clear the dirt, then drill deeper and raise the auger
again. Repeat this procedure until the desired hole
depth is reached.
• Do not shovel dirt away from a rotating auger as the
shovel can be caught and thrown by the auger.
• Disengage the power-take-off when traveling between
holes.
IT IS ESSENTIAL THAT EVERYONE INVOLVED IN
THE ASSEMBLY, OPERATION, TRANSPORT, MAIN-
TENANCE, AND STORAGE OF THIS EQUIPMENT BE
AWARE, CONCERNED, PRUDENT, AND PROPERLY
TRAINED IN SAFETY.
DIGGING A HOLE: Position the tractor so that the
auger point is placed where the hole is to be. Lower the
auger so that the point touches the ground. The point of
the auger should be approximately 3” back of center of
the gearbox. As the auger works into the ground, this
slight angle will straighten, due to the pivoting action of
the boom downward. If the auger has a side tilt, correct
with the lift arm adjustment on the tractor hitch.
If the auger tilts too far forward or to the rear, it may be
necessary to move the tractor slightly. Be careful not to
bend the auger.
The post hole digger auger is free-swinging, and care
should be taken while transporting the machine. DO NOT
transport the post hole digger while the PTO is engaged
as this could cause the universal joints of the PTO drive-
line into a sharp operating angle and cause failure of the
driveline.
(OWNER RESPONSIBILITY)
____ Review and follow safety rules and safety signs on
pages 3 through 11.
____ Check that post hole digger is properly and
securely attached to tractor.
____ Make sure driveline spring-activated locking pin or
locking balls operate freely and are seated firmly in
tractor PTO spline groove.
____ Lubricate all grease fitting locations. Make sure
PTO shaft slip joint is lubricated.
____ Check to be sure gear lube runs out the small
check plug on side of gearbox.
____ Check that all hardware is properly installed.
____ Check to ensure blades are sharp and secure and
cutting edges are positioned correctly.
____ Check that all shields and guards are properly
installed and in good condition.
____ Set tractor PTO gear select lever for 540 rpm
operation.
• Thoroughly read and understand your Operator’s
Manuals.
• Before beginning operation, clear area of objects that
wrap around the auger or might be thrown. Contact
local utility company to make certain there are no
buried gas lines, electrical cables, etc., in the work
area. Check for ditches, stumps, holes, or other
obstacles that could cause the tractor to roll.
• Layout and mark where you want to dig your holes.
• ALL persons should be at least twenty-five (25’) away.
Clear the area of helpers, bystanders, especially
children.
• Do not allow anyone to stand behind, or to the side of
a rotating auger.
• To dig properly, your digger must be able to raise or
lower through the highest and lowest points of your lift
arm travel without binding against the tractor frame.
Check carefully BEFORE attaching the auger. If it
does bind, adjust the tractor 3 pt. linkage so that all
movement is free.
PREPARATION PROCEDURE
NOTE: Use stabilizer bars, adjustable sway chains,
or sway blocks on your tractor lift arms to keep the
post hole digger from swinging side to side. Adjust
as tightly as practical for best performance.
Slide the auger (Ref. #1) over the large shaft of the
gearbox and secure it with the two bolts.
NOTE: Please refer to the drawings (Figures B through
D) as to the proper mounting pattern for the cutting
edges. Correct mounting of the cutting edges will assure
a complete cut of earth by the auger.
Attach the handle to the right side of the gearbox by
inserting the handle into the hole in the gearbox. Install
the

” bolt and tighten. The handle is to adjust the
auger position as you lower the auger to the ground.You
should be able to easily reach the handle while seated
and as you operate the 3 pt. hitch raise/lower control.
NOTE: It may be necessary to bend the handle to put it
in the best position for you to reach. If the handle is too
long for your tractor, remove the plastic handle grip and
cut the handle as required.
NOTE: If the handle is too short for your tractor’s seat
and 3 pt. hitch configuration, take the handle to a welding
shop and have it lengthened as required.
