SAFETY INSTRUCTIONS
(continued)
EQUIPMENT SAFETY GUIDELINES
Safety of the operator is one of the main concerns in designing and developing a new piece of equipment.
Designers and manufacturers build in as many safety features as possible. However, every year many
accidents occur which could have been avoided by a few seconds of thought and a more careful approach to
handling equipment. You, the operator, can avoid many accidents by observing the following precautions in this
section. To avoid personal injury, study the following precautions and insist those working with you, or for you,
follow them.
In order to provide a better view, certain photographs or illustrations in this manual may show an assembly with
a safety shield removed. However, equipment should never be operated in this condition. Keep all shields in
place. If shield removal becomes necessary for repairs, replace the shield prior to use.
Replace any CAUTION, WARNING, DANGER or instruction safety sign that is not readable or is missing. Do
not paint over, remove or deface any safety signs or warning signs on your equipment. Observe all safety signs
and practice the instruction on them. Review the safety instructions with all users annually.
This equipment is dangerous to children and persons unfamiliar with its operation. The operator should be a
responsible adult familiar with farm machinery and trained in this equipment’s operations. Do not allow persons to operate or assemble this unit until they have read this manual and have developed a thorough
understanding of the safety precautions and of how it works.
To prevent injury or death, use a tractor equipped with a Roll-Over Protective System (ROPS). Keep foldable
ROPS systems in “locked up” position at all times.
Never use alcoholic beverages or drugs which can hinder alertness or coordination while operating this
equipment. Consult your doctor about operating this machine while taking prescription or over the counter
medications.
Personal protection equipment including hard hat, safety glasses, safety shoes, and gloves are recommended
during assembly, installation, operation, adjustment, maintaining, repairing, removal, or moving the implement.
Do not allow long hair, loose fitting clothing or jewelry to be around moving parts.
Never exceed the limits of a piece of machinery. If its ability to do a job, or to do so safely, is in question –
DON’T TRY IT.
Do not modify the equipment in any way. Unauthorized modification may impair the function and/or safety and
could affect the life of the equipment.
In addition to the design and configuration of this implement, including Safety Signs and Safety Equipment,
hazard control and accident prevention are dependent upon the awareness, concern, prudence, and proper
training of personnel involved in the operation, transport, maintenance, and storage of the machine. Refer also
to Safety Messages and Operation Instructions in each of the appropriate sections of the Tractor and
Implement Manuals. Pay close attention to the Safety Signs affixed to the Tractor and the Implement.

SAFETY INSTRUCTIONS
(continued)
OPERATIONAL SAFETY
Start tractor only when properly seated in the tractor seat. Starting a tractor in gear can result in injury or death.
Do not mount or dismount the tractor while the tractor is moving. Mount or dismount the tractor only when the
tractor and all moving parts are completely stopped.
Operate the tractor and/or implement controls only while properly seated in the tractor seat with the seat belt
securely fastened around you. Inadvertent movement of the tractor or implement may cause serious injury or
death.
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 is within twenty-five feet (25’) of the digger when it is started. Do not operate the
digger with another person near, or in contact with, any part of the digger, PTO driveline, or auger. Serious
personal injury or death may result if any attempt is made to assist digger operation by hand.
Keep all helpers and bystanders twenty-five feet (25’) from an operating digger. Only properly trained people
should operate this machine. It is recommended the tractor be equipped with a Rollover Protection System
(ROPS) and a seat belt that is used. Always stop the PTO, set brake, shut off the tractor engine, remove the
tractor key, and allow auger to come to a complete stop before dismounting tractor. Never leave equipment
unattended with the tractor running.
Never leave the tractor and implement unattended while the implement is in the lifted position. Accidental operation of lifting lever or a hydraulic failure may cause sudden drop of unit with injury or death by crushing.
Know your controls and how to stop tractor, engine, and implement quickly in an emergency. Read this manual and the one provided with your tractor.
Clear area of stones, branches or other debris that might be thrown or entangled, causing injury or damage.
Operate only in daylight or good artificial light.
Make sure driveline spring-activated locking pin or balls operate freely and are seated firmly in tractor PTO
stub shaft groove.
Do not allow children or others to ride on the tractor with an operator. Riders are subject to injury such as being
struck by foreign objects or being thrown off. Riders obstruct the operator’s view resulting in unsafe operation.
Never allow anyone to ride on the implement!
Never allow children to play on or around tractor or implement. Children can slip or fall off the equipment and
be injured or killed. Inadvertent contact with controls can cause the implement to shift or fall crushing themselves or others.
Ensure that all safety shielding and safety signs are properly installed and in good condition. If a safety shield
or guard is removed for any reason, it must be replaced before the machine is again operated. Always use,
and maintain in place, all power take off guards furnished with the tractor as well as the power take off guards
and shields furnished with the digger.

SAFETY INSTRUCTIONS
(continued)
OPERATIONAL SAFETY (continued)
This digger is designed for use only on tractors with 540 RPM power take off.
Do not operate the post hole digger near existing fence wire. Fencing wire, loose wire, cable, landscape
webbing or other similar debris can become entangled in the auger and be rapidly pulled into the auger along
with bystanders in contact with the material. This can result in serious injury or death. Inspect the area before
digging and remove any fencing material, wire, cable, chain, rope, landscaping webbing or other similar debris
that could become entangled in the auger. Keep all bystanders 25 feet away from the auger and any wire of
fencing material near the auger.
Never place yourself or allow anyone between or near the tractor and digger while implement is in operation.
Do not walk or work under a raised digger or attachment unless it is securely blocked or held in position. Do
not depend on the tractor hydraulic system to hold the digger or attachment in place.
A heavy load can cause instability of the tractor. Use extreme care during travel. Slow down on turns and watch
out for bumps. The tractor may need front counter-weights to counter-balance the weight of the digger.
Do not allow riders on the digger or tractor at any time. There is no safe place for any riders.
Know where the utilities are: Before operating, call your local utilities (call 811 or 1-800-258-0808) for location
of buried utility lines, gas, water, sewer, and telephone, as well as any other hazard you may encounter.
Do not allow anyone who is not familiar with the safety rules and operation instructions to use this Post Hole
Digger.
Never allow children to operate or be around this digger.
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.
Never replace the shear bolt OR auger retaining bolt with any length other than what is specified in this manual. A longer, or protruding fastener is more likely to grab loose clothing or gloves which can result in serious
injury or death.
Do not operate digger on steep hillsides. When digging on uneven or hilly terrain, position the tractor with the
Post Hole Digger uphill. With the Post Hole Digger downhill, the tractor could tip when attempting to pull the
auger from its hole.
NEVER put hands on the post hole digger auger, gearbox, or boom to locate the auger when there is any sign
of rotation of the driveline or auger. Post hole diggers are operated by one person from the tractor seat. Keep
all bystanders and/or coworkers away from the post hole digger.

SAFETY INSTRUCTIONS
(continued)
OPERATIONAL SAFETY (continued)
Inspect the entire machine periodically as indicated in the Maintenance Section of this manual. Look for loose
fasteners, worn or broken parts, pinched hydraulic hoses, and leaky or loose fittings. Make sure all pins have
cotter pins and washers. Serious injury may occur from not maintaining this machine in good working order.
To prevent rapid wear of U-Joints and possible failure of drivelines, never lift auger point more than 8” off the
ground with PTO operating.
To prevent possible instantaneous driveline failure, never move digger from hole-to-hole or transport while
auger is rotating. This could lead to injury from flying pieces of the failed driveline.
Relieve hydraulic pressure prior to doing any maintenance or repair work on the implement. Place the implement on the ground or securely blocked up, disengage the PTO, and turn off the tractor engine. Push and pull
the remote hydraulic lever in and out several times prior to starting any maintenance or repair work.
To prevent entanglement and possible serious injury or death, never use body weight to try to push auger into
the ground.
Worn cutting edges or a slightly rounded center point can seriously effect auger penetration. Check for wear
before each use, replace as necessary.
Do not shovel dirt away from a rotating auger as the shovel can be caught and thrown by the auger.
Do not operate the Post Hole Digger without all safety shields and guards in place.
Take all possible precautions when leaving unit unattended: Disengage PTO, lower 3 pt., set parking brake,
stop engine and remove key from ignition. Park in level area.
Before operating equipment: if you have any questions regarding the proper assembly or operation, contact
your dealer or representative.
MAINTENANCE SAFETY
Good maintenance is your responsibility. Poor maintenance is an invitation to trouble.
Before working on this machine, drive to a level area, disengage the PTO, lower implement (or if working
underneath, raise and block securely), shut off the engine, set the brakes, and remove the ignition keys.
Disconnect the PTO shaft from the tractor PTO before servicing the implement.
Always use two people to handle heavy, unwieldy components during assembly, installation, removal, or
moving the digger.
Never work under equipment unless it is blocked securely. Never depend on hydraulic system to keep implement in raised position.
10
SAFETY INSTRUCTIONS
(continued)
MAINTENANCE SAFETY (continued)
Keep all persons away from operator control area while performing adjustments, service, or maintenance.
Periodically tighten all bolts, nuts and screws and check that all cotter pins are properly installed to ensure unit
is in a safe condition.
When completing a maintenance or service function, make sure all safety shields and devices are installed
before placing unit in service.
Never use your hands to locate a hydraulic leak on attachments. Use a small piece of cardboard or wood.
Hydraulic fluid escaping under pressure can penetrate the skin. Openings in the skin and minor cuts are
susceptible to infection from hydraulic fluid. If injured by escaping hydraulic fluid, see a doctor at once.
Gangrene and death can result. Without immediate medical treatment, serious infection and reactions can
occur.
Safety is a primary concern in the design, manufacture, sale, and use of Post Hole Diggers. As manufacturers of Post
Hole Diggers, we want to confirm to you, our customers, our concern for safety.
Our current production machines include, as standard equipment, guards or shields for auger adapters, drivelines,
input shafts, and safety signs. Older machines can be retrofitted to add these new guards or shields and, or course,
safety signs. If you have an older machine which does not have current standard safety equipment, please contact
your dealer about bringing your machine up to the current level of safety.
Where replacement parts are necessary for periodic maintenance and servicing, genuine factory replacement parts
must be used to restore your equipment to original specifications. The manufacturer will not claim responsibility for use
of unapproved parts and/or accessories and other damages as a result of their use.
If equipment has been altered in any way from original design, the manufacturer does not accept any liability for injury
or warranty.
TRANSPORT SAFETY
Comply with state and local laws governing highway safety and movement of farm machinery on public roads.
When driving the tractor and equipment on the road or highway under 20 mph (32 kph) at night or during the
day, use flashing amber warning lights and a slow moving vehicle (SMV) identification emblem.
Make sure post hole digger transported on tractor rear 3 pt. hitch does not obstruct visibility of tractor’s flashing lights or SMV sign.
Reduce speed when transporting mounted implements to avoid bouncing and momentary loss of steering
control.
11
SAFETY INSTRUCTIONS
(continued)
TRANSPORT SAFETY (continued)
Be aware of the operating conditions. Do not operate the tractor with weak or faulty brakes. When operating
down a hill or on wet or rain slick roads, the braking distance increases; use extreme care and reduce your
speed in these conditions. When operating in traffic, always use the tractor’s flashing warning lights and reduce
your speed. Be aware of traffic around you and watch out for the other guy.
Always be sure the implement is in the proper raised position and the PTO is turned off for transport.
Turn curves or go up or down hills only at a low speed and at a gradual steering angle. Make certain that at
least 20% of the tractor’s weight is on the front wheels to maintain safe steerage. Slow down on rough or
uneven surfaces, and loose gravel.
Use extreme care and maintain minimum ground speed when transporting on hillside, over rough ground and
when operating close to ditches or fences. Be careful when turning sharp corners.
Never allow riders on either tractor or implement. Falling off can kill.
STORAGE SAFETY
Following operation, or when unhooking, stop the tractor, set the brakes, disengage the PTO, shut off the
engine and remove the ignition keys.
Use extreme care to keep feet and hands from under the unit and clear of any pinch points. Never stand or
allow another person to stand between a running tractor and the unit when disconnecting the implement from
the tractor 3-point hitch.
Do not park equipment where it will be exposed to livestock for long periods of time. Damage and livestock
injury could result.
Store the unit in an area away from human activity. Do not permit children to play on or around the stored unit.
Make sure all parked machines are on a hard, level surface and engage all safety devices. Storage location
should be level and solid to make connecting and unconnecting to power unit easy.
NOTE: The optional parking stand may be used when post hole digger is not in operation. It will help prolong digger’s
life by keeping the unit off the ground where moisture and debris are more likely to collect causing undue damage to
the digger. Also, the parking stand aids in mounting and dismounting the post hole digger to and from the tractor.

INSTRUCTIONS
Unpack all the bundles and lay out various parts. Start
with the yoke (Ref. #2). Place the pull pins (Ref. #17)
through the holes in the legs of the yoke and secure with
nuts and lock washers.
TRACTOR REQUIREMENTS
AND PREPARATION
The Model 2403 3-pt. mounted post hole digger will fit
most Category I and Category II tractors equipped with a
standard 3-pt. hitch. The Model 2403 Digger will handle
up to 24 inch diameter augers.
NOTE: For Category I and II tractors, place the pull pins
on the outside of the yoke legs as shown in the diagram.
For smaller tractors, it may work better to place the pull
pins on the inner side of the yoke legs.
The Model 2403 post hole digger is designed for use
with tractors up to 60 hp. The tractor must have a Power
Take Off (PTO) rated for 540 rpm and with a 6-spline,
13/8” diameter output shaft.
The pins are Category I (7/8” dia.). If your tractor is
Category II, then lift arm bushings are required to
properly fit the 11/8” dia. Cat. II lift arm balls. (Bushings not
supplied.) Place the lift arms of your tractor over the pull
pins in the yoke and secure with linchpins (not supplied).
An optional hydraulic down-pressure kit is available to
provide an additional 350-450 lbs. of down-pressure in
tough digging conditions.
NOTE: Always use adapter bushings when using
Category I pins on a Category II hitch. Trying to use Cat.
I pins in a Cat. II hitch without bushings will result in a
very loose fit and the post hole digger will be unstable.
Check the tractor’s 3-pt. hydraulic lift system. It should
operate up and down smoothly and have enough power
to lift the dirt-loaded auger out of the hole. Refer to your
tractor operator’s manual or dealer for any adjustments
necessary to put the 3-pt. hydraulic lift system in good
working order.
Pin end of digger boom (Ref. #1) to tractor toplink
bracket. Raise boom by hand – check that it doesn’t hit
any part of toplink bracket (some tractors only). If
problem exists, change hole location and re-check.
Failure to check can result in damage to tractor or
boom. Cat. I tractors need toplink bushing. Connect yoke
to boom with pin (Ref. #15) and cotter pins.
WARNING
Power unit must be equipped with ROPS or ROPS
cab and seat belt. Keep seat belt securely fastened.
Falling off power unit can result in death from being
run over or crushed. Keep foldable ROPS systems in
“locked up” position at all times.
Install the plastic manual holder on the bottom of the
flat plate welded to the yoke. Locate the manual holder
with the cap facing away from the post hole digger. Use
the two 1/4” x 1” bolts to mount the manual holder.
Check the shield over the PTO stub shaft. Make sure it
is in good condition and bolted securely to the tractor.
Purchase a new shield if old shield is damaged or
missing.
It is recommended that the pair of gearbox output
guards, and the gearbox input guard be assembled on
the gearbox before the gearbox is fastened to the boom.
Place the gearbox upside down on the floor.
Tractor must be equipped with stabilizer bars, adjustable
sway chains, or sway blocks to keep the post hole digger
from swinging side to side.
Install the formed metal gearbox output shields (Ref.
#6) on the gearbox. A socket with a long extension
makes this an easy installation. Use the 3/8” x 3/4” bolts
and 3/8” flat washers to fasten the guards.
This product is designed to dig holes in the soil when
attached to the 3-point hitch and power-take-off of a
tractor. It is not intended for any other use. Using the
product for anything other than digging holes could result
in serious injury or death.
Clean and check the input shaft of the gearbox. If any
nicks or dents have occurred in shipping, lightly file to
remove and make the shaft smooth.
ASSEMBLY AND MOUNTING
Install the input guard backplate (Ref. #7) on the front
input end of the gearbox using the four bolts in the gearbox.
Refer to the “exploded view” of the post hole digger on
page 24 of this manual. Become familiar with the relationship of the various components and parts shown.
Attach the gearbox (Ref. #3) to the boom using the
gearbox hanger pin (Ref. #25) and secure it with the two
cotter pins (Ref. #26).

INSTRUCTIONS
(continued)
To connect the implement driveline to the tractor PTO
output shaft, pull the driveline yoke collar back and align
the grooves and splines of the yoke with those of the
PTO shaft. Push. the driveline yoke onto the PTO shaft,
release the locking collar, and position the yoke until the
locking collar balls are seated onto the PTO shaft. Push
and pull the driveline back and forth several times to
ensure a secure attachment.
GEARBOX OIL FILL
NOTE: The gearbox is shipped WITHOUT lubricant, so it
will be necessary to fill before use. With the gearbox in a
level position, fill to the side inspection hole with a good
90 wt. gear lubricant. Gearbox holds 168 fluid oz. Check
often and add lubricant if necessary.
DRIVELINE ATTACHMENT
The driveline yoke and tractor PTO shaft must be dirt
free and greased for attachment.
WARNING
Figure A
Before operating the Implement, check to make
sure the Implement input driveline will not bottom
out or become disengaged. Bottoming out occurs
when the inner shaft penetrates the outer housing
until the assembly becomes solid, it can shorten no
more. Bottoming out can cause serious damage to
the Tractor PTO by pushing the PTO into the Tractor
and through the support bearings or downward onto
the PTO shaft, breaking it off. A broken driveline can
cause personal injury.
On the implement end of the PTO shaft there is a hole
in the yoke just forward of the 3/8” shear bolt (see Figure
A). This hole is for the 1/4” diameter x 21/4” long roll pin
(Ref. #21). When this roll pin is driven in this hole, the
center of the roll pin engages into the groove on the front
of the gearbox input shaft. This prevents the PTO
assembly from coming off if the 3/8” shear bolt should
shear.
Carefully start the 1/4” (Ref. #21) roll pin into the hole. At
this time, only tap the roll pin about 1/4” into the hole. DO
NOT tap the roll pin far enough into the hole so that it
enters the 1.25” diameter shaft hole. If the roll pin is
installed too far, you will not be able to install the PTO driveline on the input shaft of the gearbox. (Pre-starting the
roll pin now is much easier than trying to put the roll pin
in when the driveline end is on the gearbox input shaft.)
Grease the input shaft of the gearbox before installing
the PTO shaft. This reduces the chance of the PTO shaft
yoke from galling to the input shaft if the shear bolt
should break.
Slip the two telescoping ends of the PTO shaft together. Spray WD-40 into the yoke and wipe. This should
remove some of the paint and make it easier to slide the
yoke onto the input shaft of the gearbox. Install the
unsplined end on the gearbox input shaft and bolt it in
place with the 3/8” x 3” shear bolt (Grade 2) (Ref. #18) and
secure with the lock washer and nut.
Now, using a drift punch, tap the 1/4” roll pin all the way
into the hole.
Slowly raise and lower the digger without the auger on.
Watch to see that the PTO driveline and/or shields do not
separate or get into a bind. Check to see if gearbox end
will lower to the ground. If it will not go all the way down,
then check to see if the PTO shaft is bottoming.
NOTE: Do NOT use any PTO extension adapter
between tractor PTO and digger driveline.
When fitting the unit to the tractor, the telescoping driveline must be inspected to ensure that at its most compressed position, the profiles do not “bottom out”, and
when at its farthest extended position, there is sufficient
engagement between the profiles to operate safely. At its
shortest length, there must be at least a 1” clearance
between each profile end and opposite profile universal
joint. At it farthest operating extension, a minimum profile
engagement of 6” must be maintained. If driveline has
less than 6” overlap, do not use. Contact your dealer.
Minimum Overlap
WARNING
Do not install a longer shear bolt or other longer
fastener! A protruding fastener is more likely to grab
loose clothing and can cause serious injury or death.

INSTRUCTIONS
(continued)
With the PTO driveline installed, place the input guard
(Ref. #9) on the input guard back plate (Ref. #7) and fasten with the two threaded knobs (Ref. #9).
PREPARATION PROCEDURE
NOTE: The input guard back and input guard are
chained together. This will keep the input guard from
being mis-placed and make it more likely to be properly
installed.
• Before beginning operation, clear area of objects that
wrap around the auger or might be thrown. Contact
local utility company (call 811) 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 over.
• Thoroughly read and understand your Operator’s
Manuals.
Install the Slow Moving Vehicle (SMV) bracket on the
rear top of the gearbox. This requires removing the center rear bolt of the top cap of the gearbox. Place the
bracket in position and re-install the bolt.
• 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.
Place the SMV sign on the rear of the bracket and fasten with the two #10 - 24 x ½” screws and nuts (Ref. #38
and #39).
• 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.
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.
NOTE: 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.
CAUTION
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.
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.
Do not operate the post hole digger near existing fence
wire. Fencing wire, loose wire, cable, landscape webbing
or other similar debris can become entangled in the
auger and be rapidly pulled into the auger along with
bystanders in contact with the material. This can result in
serious injury or death. Inspect the area before digging
and remove any items that could become entangled in
the auger. Keep all bystanders 25 feet away from the
auger and any wire of fencing material near the auger.
Slide the auger over the 2” output shaft of the gearbox
and secure it with the two bolts. Use a socket wrench with
an extension to tighten the auger retaining bolts. The oval
shaped holes in the sides of the two piece output shaft
guard will align with the auger bolts.
NOTE: Please refer to the drawings (page 25, 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.
If you have ANY questions, regarding the proper
operation of this digger, contact your dealer or the
manufacturer.
17
OPERATING INSTRUCTIONS
• In some types of soil, it may be necessary to hold back
against the auger screw action by moving the
hydraulic control lever to “HOLD” or “RAISE” position
to keep the auger from screwing into the ground.
PRE-OPERATION CHECKLIST
(OPERATOR RESPONSIBILITY)
____ Review and follow safety rules and safety signs on
pages 5 through 14.
• 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 #50072112.)
____ 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 driveline slip joint is lubricated.
• If you have difficulty penetrating hard ground, refer to
Owner’s Manual Trouble-shooting section for
suggestions.
____ Check to be sure gear lube runs out the small
check plug on side of gearbox.
• 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.
____ Check that all hardware is properly installed.
____ Check to ensure cutting edges are sharp, secure
and 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.
• NEVER allow anyone to shovel dirt away from a rotating auger as the shovel can be caught and thrown by
the auger.
____ DO NOT operate the unit if the pre-operation
inspection reveals any condition affecting safe
operation.
• Disengage the power-take-off when traveling between
holes.
IT IS ESSENTIAL THAT EVERYONE INVOLVED IN
THE ASSEMBLY, OPERATION, TRANSPORT, MAINTENANCE, AND STORAGE OF THIS EQUIPMENT BE
AWARE, CONCERNED, PRUDENT, AND PROPERLY
TRAINED IN SAFETY.
OPERATION
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 twentyfive feet (25’) of the digger when it is operating.
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 driveline into a sharp operating angle and cause failure of the
driveline.
• 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.
DIGGING A HOLE: Position the tractor so that the
• 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 engaging the PTO.
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.
• Increase the speed as required so dirt is conveyed
from the hole. Most hole digging is generally best with
the tractor at no more than half throttle speed (PTO
speed @ approx. 300 rpm).
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.
• Under no circumstances should the PTO be run in
excess of 540 rpm.
18
OPERATION INSTRUCTIONS
(continued)
NOTE: Be sure auger is completely retracted from
the hole before attempting to move the tractor.
WARNING
■ Never locate auger by putting hands on auger,
gearbox, or boom when there is any sign of rotation
on the driveline or auger or if the tractor is running.
Once the auger is digging a hole, the tractor cannot be
moved. Make sure brake is set securely. If the tractor
does move while the auger is in a hole, damage to the
gearbox or auger can result (not covered by
warranty).
■ Remain on the tractor seat while operating the
post hole digger. Assisting the machine by hand can
result in possible injury or death.
■ Never use body weight to help the auger penetrate
the ground.
Before dismounting tractor, you must always set park
brake, lower the three-point attachment to the ground,
turn off tractor and remove ignition key.
Engage the tractor PTO with the engine at idle (or below
1000 engine RPM). As the auger penetrates the ground,
lower the unit slowly with the 3 pt. hydraulic system. DO
NOT LET THE AUGER SCREW ITSELF INTO THE
GROUND! Auger must dig with the dirt breaking up and
being carried to the top by the auger flighting.
Underground utilities – Contact appropriate
agencies to determine if hazardous items are buried
under the digging site BEFORE DIGGING! Be certain
underground utilities have been called to locate
underground electric, gas, telephone, and other
lines. Call 811 or 1-800-258-0808. Be sure post hole
digger operator is properly informed. WHEN IN
DOUBT, DO NOT DIG!
Once the hole is dug to the desired depth raise the
auger while rotating to bring the dirt out of the hole. To get
a clean hole, it is sometimes best to lower the auger into
the hole with the auger turning and then, when at the bottom, stop the rotation and raise the auger while not turning. This brings the dirt up with little left in the hole.
Cutting edges and fishtail type center points are
replaceable. They should be sharpened or replaced
when worn. In hard digging conditions, a fishtail type
center point is more aggressive.
For best results, allow the digger to dig about half the
required depth, then lift it partially out of the hole to
remove dirt and then re-enter hole and finish to the
desired depth.
NOTE: If you have a rocky or large root soil condition, it
is recommended that a heavy duty auger by used.
If you encounter rocks or roots that catch the auger and
cause shear bolts to break, then remove the auger from
the hole and use a large, heavy pry bar to break up the
obstructing rock. A large root may have to be chopped to
remove.
DO NOT LET THE DIGGER DIG SO DEEP THAT THE
PTO SHAFT IS RUNNING IN THE DIRT. If hole needs
to be deeper, use an auger extension. (Part #50072107)
Once the hole is completed, disengage PTO, raise
auger to a safe height, release park brake and pull ahead
to the next hole location with tractor.
DANGER
Do not attempt to free the auger by hand while the
PTO is connected. Disconnect the PTO driveline from
the tractor before attempting to free the auger.
Never raise point of the auger over 8” off the ground
with PTO operating.
If auger becomes lodged below ground, DO NOT
attempt to lift auger out of ground by hydraulic lift power
alone. Turn tractor off and disconnect PTO driveline from
the tractor. Reverse the rotation of the auger by several
turns. This can be accomplished by using a large pipe
wrench and turning the auger backwards until it clears.
Extreme rocking or lifting loads while trying to clear stuck
augers can cause auger, gearbox, or boom failure.
CAUTION
Do not shovel dirt away from a turning auger, as the
shovel can be caught by the auger and thrown. Do
not allow anyone to stand behind or to the side of an
operating auger. ALL persons should be at least 25
feet away.
19
OPERATION INSTRUCTIONS
(continued)
Transport to and from your digging site at a safe speed
and in such a manner that faster moving vehicles may
pass safely. A slow moving vehicle sign should always be
properly displayed when using a public road or right-of
way.
NOTE: Be careful when raising the auger as high
as your tractor’s 3 pt. hitch can go. This can put
the PTO shaft universal joints at an extreme
angle and cause damage to the PTO shaft! It is
best to raise the auger just enough to clear the
hole when the PTO is engaged.
It is recommended NOT to raise the auger while
PTO is running more than eight (8) inches above
the ground.
REMOVING DIGGER FROM TRACTOR
Post hole diggers when off the tractor, can be an
awkward piece of equipment to handle.
NOTE: Never exceed the recommended auger
capacity of the post hole digger. The Model 2403
standard duty digger is designed for use with augers
up to 24-inch diameter. Use of an incorrect auger or
auger extension can cause equipment damage, loss
of operator control and personal injury.
Always shut the tractor completely down, place the
transmission in park, disengage the PTO and set the
parking brake before you or anyone else attempts to connect or disconnect the implement.
Storage location should be level and solid to make connecting and disconnecting easy. Store in a clean, dry
location away from children and livestock. Keep the driveline yoke from sitting in dirt or water.
TRANSPORTING
Pay particular close attention to the Safety Messages
regarding transport. Avoid unnecessary injuries and
equipment damage by exercising cautious, conscientious
travel procedures.
Use extreme care to keep feet and hands from under
the unit and clear of any pinch points. Never stand or
allow another person to stand between a running tractor
and the unit when disconnecting the implement from the
3-point hitch.
Read all safety warnings in the front of the manual.
The optional parking stand may be used when Post
Hole Digger is not in operation. The parking stand aids in
mounting and dismounting the Post Hole Digger to and
from the tractor.
Attaching the implement to the tractor increases the
overall length of the working unit. Allow additional
clearance for the implement to swing when turning.
CAUTION
POST HOLE DIGGER OPTIONS
When traveling on public roads, whether at night or
during the day, use accessory light and devices for
adequate warnings to operators of other vehicles.
Comply with all federal, state and local laws.
1. Heavy Duty Augers: For rocky or tough soil conditions. Check with dealer for availability.
2. 12” Auger Extension: Available for situations where
deeper holes are required. NOTE: Smaller tractors
may not raise auger high enough to clear hole when
12” auger extension is used. Order part #50072107.
DO NOT OPERATE PTO DURING TRANSPORT.
Raise the post hole digger as high as possible for
transporting.
3. Hydraulic Down Force Kit: For tough, hard soil conditions. This will allow operator to put 300-400 lbs. of
down force on the auger for tough or hard ground.
Tractor must have auxiliary hydraulic outlet. Order
part #50072112 for Model 2403 Post Hole Diggers.
(See page 26).
WARNING
Be aware of the operating conditions. Do not operate the tractor with weak or faulty brakes. When operating down a hill or on wet or rain slick roads, the
braking distance increases; use extreme care and
reduce your speed in these conditions. When operating in traffic, always use the tractor’s flashing warning lights and reduce your speed.
4. Parking Stand Kit: Kit allows the post hole digger to
be stored in an upright position. Makes connecting
and disconnecting from tractor an easy one man
operation. Order part #50072111. (See page 27).

yoke galling to the input shaft if the shear bolt should
break. If digging conditions are breaking a number of
shear bolts, then grease this location more often.
▲ Before working underneath, raise 3 pt. hitch to
desired position and block securely. Hydraulic
system leakdown and failure of mechanical or
hydraulic system can cause equipment to drop.
▲ Keep all persons away from operator control area
while performing adjustments, service or
maintenance.
BEFORE EACH USE:
A. Driveline Universal Joints – Apply multi-purpose
grease to fittings.
B. Driveline Guard – Apply 2-3 shots of multi-purpose
grease to plastic fittings.
ROUTINE MAINTENANCE
C. Driveline Shaft – Disconnect PTO driveline, pull two
sections apart, and apply thin coat of multi-purpose
grease to inside of outer (female) section.
Reassemble sections and install. Pull each section to
be sure driveline and shields are securely connected.
Make certain PTO shielding is in good condition.
DAILY CHECKS:
1. Check that all bolts, nuts, and screws are tight.
Checking the bolts and nuts on the cutting blades is
particularly important in rocky soil.
2. Check daily the level of the gearbox oil and top up to
the correct level. Check for gearbox oil leaks. It should
be noted that no warranty claim can be submitted on
a gearbox that has run dry. It is essential that the
gearbox is kept correctly filled with gearbox oil.
AT THE END OF THE SEASON:
3. Grease the PTO shaft daily.
1. Drain and change the oil in your gearbox.
4. Check the wear on the cutting blades. Sharpen them
routinely with an angle grinder or replace when worn
down too far. Keep at least two sets of cutting blades,
bolts, and nuts as spares.
2. Check and replace, where necessary, blades, bolts,
nuts on the machine.
3. Clean machine and touch up any rust spots that may
have appeared.
4. Replace any safety signs if damaged or painted over.
LUBRICATION INFORMATION
5. Make sure PTO driveline yoke and gearbox input shaft
are clean and free of burrs. Keep well lubricated to
prevent galling of yoke and input shaft when shear
bolt becomes sheared.
The accompanying chart gives the frequency of lubrication in operating hours, based on normal conditions.
Severe or unusual conditions may require more frequent
lubrication.
Do not let excess grease collect on or around parts,
particularly when operating in sandy areas.
Use an SAE 90W gear lube in gearbox.
Use a lithium grease of NO. 2 consistency with a MOLY
(molybdenum disulfide) additive for all locations. Be sure
to clean fittings thoroughly before attaching grease gun.
When applied according to the lubrication chart, one
good pump of most guns is sufficient. Do not over grease.
6. Keep all shields in place. Order new shields if damaged or missing.
7. Keep cutting edges sharp. Sharp cutting edges dig
easier and better. Outer cutting edges on larger
augers wear faster than inner cutting edges; switching
teeth will even wear.
8. Store implement in clean, dry location, away from
children, animals, or traffic area.

DOWN FORCE KIT INSTRUCTIONS
KIT #50072112 (FOR MODEL 2403 POST HOLE DIGGER)
INSTALLATION
OPERATION
1. Refer to the parts illustration and install the Down
Force Kit parts as shown. Remove the boom lift pin
that connects yoke assembly to the post hole digger
boom.
Lower the Post Hole Digger in the usual manner and
allow the auger to dig. As down force is needed, apply it
carefully and in small amounts by using the control lever
on the tractor remote outlet. It will be necessary to continue lowering the lift arms as the auger digs. Applying
too much down force at one time can stall the auger and
possibly cause the shear bolt on the post hole digger
input shaft to shear. NOTE: REPLACE THE SHEAR
BOLT WITH A GRADE #2 (SOFT) BOLT ONLY. Using
a (HARD) bolt can damage the auger, PTO driveline or
gearbox and void the warranty.
2. Place pivot plates (1) on inside of yoke assembly and
replace boom lift pin. Secure with cotter pin previously removed.
3. Install bolt (2), spacer (4), and lock nut (3) in middle
hole.
The boom can be raised in the normal manner without relieving the down force cylinder pressure. Hydraulic
cylinder will retract.
4. Install second bolt (2), two spacer sleeves (5), base
end of cylinder (6), and lock nut (3) in top hole.
NOTE: DAMAGE CAN OCCUR IF HOSES ARE
NOT CONNECTED CORRECTLY. If the return
hydraulic hose is connected to the other tractor remote
outlet instead of directly to the tractor hydraulic reservoir, severe damage will possibly occur to the hydraulic
cylinder and post hole digger when the boom is raised.
Make sure hydraulic hoses are connected correctly.
5. With cylinder retracted, attach cylinder to lug on top of
boom with 1/2" x 2" bolt (7) and nut (8).
6. Install pressure hose (10) to top port on the relief
valve. Attach male coupler (not supplied) to other end
of hose (10) and connect to tractor remote outlet.
7. Attach adapter (13) and return hose (11) to side port
on the relief valve. Connect return hose directly to tractor hydraulic reservoir.
NOTE: DO NOT CONNECT THE RETURN HOSE TO
A REMOTE OUTLET. Remote outlet ports are
blocked in the neutral position and will damage the
hydraulic cylinder or other parts when boom is raised.

6. Insert the two stand legs (2) into the socket on the
front of the parking stand base plate. Secure with two
locking pins (3).
7. Lower digger until the two legs and the auger form a
tripod. This will support the post hole digger in a vertical position.
8. Remove 3 point arms and driveline from the tractor.
Then disconnect the boom from tractor.
9. Attach the PTO hook (1) to the boom of the digger.
10. Hang the driveline from the hook to help prevent dirt
and debris from accumulating in the locking collar on
the driveline PTO yoke.
The Parking Stand Kit has a plate that bolts to the bottom of the gearbox. Two removable legs go into sockets welded on the plate. The legs are pinned in place. The two legs and the auger form a tripod which supports the post hole
digger in a vertical position. A formed hook keeps the PTO driveline end off the ground.
This makes connecting or removing the post hole digger from the tractor a one man job.
Make sure the post hole digger will be located on a solid surface and in a location away from children, animals, or
traffic areas.
