Safety - Post Hole Digger
Safety
All implements with moving parts are potentially hazardous. There is no substitute for a cautious,
safe-minded operator who recognizes the potential hazards and follows reasonable safety practices. The manufacturer has designed this implement to be used with all its safety equipment properly attached to minimize the chance of accidents.
Before You Start
Read the safety messages on the implement and shown in your manual.
Observe the rules of safety and common sense!
The safety alert symbol means…
ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!
This safety alert symbol identifies important safety warning messages. Carefully
read each warning message that follows. Failure to understand and obey a safety
warning, or ­recognize a safety hazard, could result in an injury or death to you or
others around you. The operator is ultimately responsible for the safety of himself,
as well as others, in the operating area of the tractor and attached equipment.
Understand Signal Words
Note the use of the signal words DANGER, WARNING and CAUTION with the safety messages.
The appropriate signal word for each has been selected using the following guidelines:
DANGER: Indicates an imminently hazardous situation that, if not avoided, will result in death
or serious injury. This signal word is to be limited to the most extreme situations typically for
machine components which, for functional purposes, cannot be guarded.
WARNING: Indicates a potentially hazardous situation that, if not avoided, could result in death or
serious injury, and includes hazards that are exposed when guards are removed. It may also be
used to alert against unsafe practices.
CAUTION: Indicates a potentially hazardous situation that, if not avoided, may result in minor or
moderate injury. It may also be used to alert against unsafe practices.
If you have questions not answered in this manual or require additional copies or the manual is
damaged, please ­contact your dealer or the manufacturer directly.
Important Safety information
Working with unfamiliar equipment can lead to careless injuries. Read this manual, and the manual for your tractor, skid steer, or forklift, before assembly or operating, to acquaint yourself with
the machines. It is the implement owner’s ­responsibility, if this machine is used by any person
other than yourself, is loaned or rented, to make certain that the operator, prior to ­operating:
1. Reads and understands the operator’s manuals.
2. Is instructed in safe and proper use.
The use of this equipment is subject to certain hazards which cannot be protected against
by mechanical means or product design. All operators of this equipment must read and
understand this entire manual, ­paying particular attention to safety and operating instructions, prior to using. If there is something in this manual you do not understand, ask your
supervisor, or your dealer, to explain it to you.

Safety - Post Hole Digger
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. Location of such safety signs is indicated in this booklet.
• Never use alcoholic beverages or drugs which can hinder alertness or coordination while
operating this e
­ quipment. Consult your doctor about operating this machine while taking
prescription medications.
• 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).
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.
• 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, Skid Steer, and Implement
Manuals. Pay close attention to the Safety Signs affixed to the Tractor, Skid Steer, and the
Implement.

Safety - Post Hole Digger
Safety Training
• Safety is a primary concern in the design and manufacture of our products. Unfortunately, our
efforts to ­provide safe equipment can be wiped out by a single careless act of an operator.
• In addition to the design and configuration of 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 equipment.
• It has been said, “The best safety device is an informed, careful operator.” We ask you to be that
kind of an operator. It is the operator’s responsibility to read and understand ALL Safety and
Operating instructions in the manual and to follow these. Accidents can be avoided.
• Working with unfamiliar equipment can lead to careless injuries. Read this manual, and the
manual for your tractor, before assembly or operating, to acquaint yourself with the machines.
It is the equipment owner’s responsibility, if this machine is used by any person other than
yourself, is loaned or rented, to make certain that the operator, prior to operating:
1. Reads and understands the operator’s manuals.
2. Is instructed in safe and proper use.
• Know your controls and how to stop tractor, engine, and loader quickly in an emergency. Read
this manual and the one provided with your tractor or skid steer.
• Train all new personnel and review instructions frequently with existing workers. A person who
has not read and understood all operating and safety instructions is not qualified to operate the
machine. An untrained operator exposes himself and bystanders to possible serious injury or
death.
• Do not allow children to operate this machine.

Safety - Post Hole Digger
Safety Signs
• Keep safety signs clean and legible at all times.
• Replace safety signs that are missing or have become illegible.
• Replaced parts that displayed a safety sign should also display the current sign.
• Safety signs are available from your Distributor or Dealer Parts Department or the factory.
How to Install Safety Signs
• Be sure that the installation area is clean and dry.
• Be sure temperature is above 50°F (10°C).
• Decide on the exact position before you remove the backing paper.
• Remove the smallest portion of the split backing paper.
• Align the sign over the specified area and carefully press the small portion with the exposed
sticky backing in place.
• Slowly peel back the remaining paper and carefully smooth the remaining portion of the sign
in place.
• Small air pockets can be pierced with a pin and smoothed out using the piece of sign backing
paper.
Preparation
• 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.
• PROLONGED EXPOSURE TO LOUD NOISE MAY CAUSE PERMANENT HEARING LOSS!
Tractors with or without implements attached can often be noisy enough to cause permanent,
partial hearing loss. We recommend that you wear hearing protection on a full-time basis if the
noise in the Operator’s position exceeds 80db. Noise over 85db on a long-term basis can cause
severe hearing loss. Noise over 90db adjacent to the Operator over a long-term basis may
cause permanent, total hearing loss. NOTE: Hearing loss from loud noise (from tractors, chain
saws, radios, and other such sources close to the ear) is cumulative over a lifetime without
hope of natural recovery.
• 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.
• Ensure that all safety shielding and safety signs are properly installed and in good condition.

Safety - Post Hole Digger
Operational Safety
• 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.
• Most accidents occur because of neglect or carelessness. 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.
• All things with moving parts are potentially hazardous. There is no substitute for a cautious,
safe-minded ­operator who recognizes potential hazards and follows reasonable safety
practices. The manufacturer has designed this digger to be used with all its safety equipment
properly attached, to minimize the chance of ­accidents. Study this manual to make sure you
have all safety equipment attached.
• 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.
• This digger is designed for use only on tractors with 540 RPM power take off.
• When the use of hand tools is required to perform any part of assembly, installation,
adjustment, maintaining, repairing, removal, or moving the digger, be sure the tools used are
designed and recommended by the tool manufacturer for that specific task.
• Never place yourself between 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.
• 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 medications.
• Do not allow riders on the digger or tractor at any time. There is no safe place for any riders.
• Before you operate the digger, check over all pins, bolts and connections to be sure all are
securely in place. Replace any damaged or worn parts immediately.
• Consult local utility companies to make certain there are no buried gas lines, electrical cables,
etc., in the work area before beginning operation.

Safety - Post Hole Digger
Operational Safety Continued
• 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 position the auger point by hand or with any tool when the tractor is running.
• Never position the auger point by putting your hands on the auger, gearbox, boom, or
driveline.
• 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 12" 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.
• Keep hands, feet, hair, jewelry, and clothing, away from all moving and/or rotating parts.
• To prevent entanglement and possible serious injury or death, never use body weight to try to
push auger into the ground.
• Worn edges or a slightly rounded 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, set parking brake,
stop engine and remove key from ignition. Park in level area.
• Always use care when operating a Post Hole Digger.
10
Safety - Post Hole Digger
Transport Safety
• Comply with state and local laws governing highway safety and movement of farm machinery
on public roads.
• The use of flashing amber lights is acceptable in most localities. However, some localities
prohibit their use. Local laws should be checked for all highway lighting and marking
requirements.
• 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.
• Always be sure the implement is in the proper raised position for transport.
• Reduce speed when transporting mounted implements to avoid bouncing and momentary loss
of steering ­control.
• Plan your route to avoid heavy traffic. Watch for traffic when operating near or crossing
roadways.
• Do not drink and drive!
• 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.
• Be a safe and courteous driver. Always yield to oncoming traffic in all situations, including
narrow bridges, intersections, etc.
Maintenance Safety
• Good maintenance is your responsibility. Poor maintenance is an invitation to trouble.
• Follow good shop practices.
- Keep service area clean and dry.
- Be sure electrical outlets and tools are properly grounded.
- Use adequate light for the job at hand.
• 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.
• 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 digger. Do not allow long hair, loose fitting clothing or jewelry to be
around moving parts.
11
Safety - Post Hole Digger
Maintenance Safety Continued
• 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.
• Keep all persons away from operator control area while performing adjustments, service, or
maintenance.
• Always use personal protection devices such as eye, hand and hearing protectors, when
performing any ­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.
• 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.
• 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.
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.
• Do not park equipment where it will be exposed to livestock for long periods of time. Damage
and livestock injury could result.
• 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.

Instructions - Post Hole Digger
Instructions
Tractor Requirements And Preparation
The model 150 3-pt. mounted post hole digger will fit most 14 to 24 hp small tractors with a
Category 0 hitch and a 540 rpm rated PTO.
NOTE: Some smaller size Category 0 lawn tractors (usually less than 14 hp) have very short lift
arms with 5/8" diameter lift arm ball ends. These smaller lawn tractors are not usually suitable for
post hole digger operation.
The model 150 post hole digger “A” frame comes with Category I lift pins (7/8" diameter). Most
small tractors are made for these size pins. If your tractor has 5/8" diameter lift arm ball ends, then
you must order Cat. I / Cat. 0 lift pins (part #590330, two required).
The model 150 post hole digger can handle 6", 9", or 12" ­diameter augers. However, the size of
auger that can be ­effectively used depends on the size of your tractor and existing soil conditions.
Example: In easy soil conditions, a 14-16 hp tractor can handle a 12" auger. If conditions are
difficult, a 9" diameter auger is probably all that a tractor that size will be able to handle.
Because of the generally low height profile of these smaller tractors, the use of 30" long augers is
recommended. (Some small tractors either cannot lift the boom high enough for use of a standard
42" length auger or tend to put the digger driveline joints at such a sharp angle, the driveline will
not perform or has a high failure rate.)
Check the tractor’s 3-pt. hydraulic lift system. It should ­operate 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 to put the 3-pt. hydraulic lift system in good working order.
Check the shield over the PTO stub shaft. Make sure it is in good condition and bolted securely to
the tractor.
Tractor must be equipped with stabilizer bars, adjustable sway chains, or sway blocks to keep the
post hole digger from s­ winging side to side.
Smaller size tractors may need front counter weights to counter-balance the weight of the post
hole digger and the weight of the dirt on the auger.
14
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.
Warning
Be sure your tractor is in good condition. Read all the
safety precautions and make sure all operators are
familiar with the safety rules of ­operation.
Instructions - Post Hole Digger
Assembly and Mounting
Unpack and lay out the various parts. Refer to the exploded view parts drawing for part
identification and the relationship of one part to the others.
Start with the “A” frame assembly. Place the pull pins (Ref. #10) through the lower holes of the
side bars (Ref. #2) and the lower cross bar (Ref. #3). Secure with nuts and lock washers.
Place the lift arm ends of your tractor over the pull pin ends in the “A” frame assembly and
secure with linchpins (not ­supplied).
Place the tractor end of the digger boom (Ref. #1) between the top link ears on the tractor and pin
in place. Use a top link bushing (5/8" to 3/4" O.D.) for Cat. 0 tractors. Swing the “A” frame up and
attach it to the adjustment channel on the boom with the 3/4" x 5-1/2" bolt and nylock nut.
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 the tractor or boom.
NOTE: When attaching the “A” frame to the boom, use the hole in the adjustment channel best
suited for your tractor. If you don’t know the best hole location, start with the middle hole.
It is recommended that the gearbox output guard, the gearbox input guard, and the PTO driveline
be assembled on the gearbox before the gearbox is fastened to the boom. Place the gearbox
upside down on the floor.
Install the formed metal gearbox output shield (Ref. #9) on the gearbox. A socket with a long
extension makes this an easy installation.
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.
Slide the plastic cone-shaped input guard on to the input shaft of the gearbox.
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 pin 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
5/16" shear bolt (Ref. #19) and secure with the lock washer and nut.
On the implement end of the PTO shaft there is a hole
in the yoke just forward of the 5/16" shear bolt (see
Figure A). This hole is for the 3/16" diameter x 1-1/4"
long roll pin (#2504011). 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 5/16" shear bolt should shear. When replacing the
shear bolt, use only a soft, Grade 2 shear bolt. DO
NOT use a hard bolt!
15
Instructions - Post Hole Digger
Assembly and Mounting - Continued
Warning
Do not install a longer bolt or other longer fastener! A
protruding fastener is more likely to grab loose clothing
and can cause serious injury or death.
Attach the gearbox (Ref. #7) to the boom using the gearbox pin (Ref. #17) and secure it with the
two ­cotter pins (Ref. #18). The gearbox should be placed so that the large shaft is pointing toward
the ground and the small shaft is pointing toward the tractor.
NOTE: The gearbox is shipped WITHOUT lubricant, so it will be necessary to fill it before use. With
the gearbox in a level position, fill to the side inspection hole with a good 90 wt. gear lubricant.
Check often and add lubricant if necessary.
Clean tractor PTO stub shaft and the inside of the splined driveline yoke. Pull the spring loaded
solid metal ring from the end of the yoke and slip the splined ­driveline yoke on the splined PTO
shaft of your tractor. Release the spring loaded ring and push the yoke on until it locks in place.
(The spring loaded ring holds ­locking balls that lock the tractor end of the PTO driveline on the
tractor PTO shaft.) Make certain the tractor PTO shield is in good condition and securely fastened
onto the tractor.
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 either change the hole location between the yoke and boom or
check to see if the PTO shaft is bottoming.
NOTE: If your tractor PTO shaft has a 1-1/8" spline, it will be necessary to obtain a 1-1/8" to 1-3/8"
sleeve spline adapter. If tractor is equipped with a 1-1/8" to 1-3/8" spline adapter extension, it may
be necessary to cut the PTO shaft off in length. Check this before putting the auger on or digging a
hole. To check, raise and lower the post hole digger with the tractor BEFORE putting the auger on.
NOTE: The use of a PTO extension could require that the PTO driveline be shortened a considerable
amount. If this is done, the driveline halves may separate when the post hole digger is raised to
transport position.
If the PTO driveline needs to be shorter, remove the ­driveline from the tractor and digger gearbox.
Lower the digger (without the auger on) until the input shaft of the gearbox is in line with the PTO
stub shaft of the tractor. (This should be the shortest distance required for the ­driveline.)
Pull the two telescoping halves of the PTO driveline apart. Connect the tractor end to the tractor
and the gearbox end to the digger gearbox (but NOT with the two halves together).
Hold the two driveline sections parallel to each other and mark each end as to how much too long
they are.
Then raise the digger to transport position and again hold the two driveline halves parallel to each
other and check for a minimum of 6" (15 cm) overlap. If driveline has less than 6" overlap, do not
use. Contact your ­dealer. If at least 6" of overlap is provided, then proceed in ­cutting the driveline.

Assembly and Mounting - Continued
1. If driveline must be cut to a shorter length,
clamp ­driveline in a well padded vise to
prevent damage to the shield. Cut off shield
where marked. Using cut-off section of shield
as a guide, cut shaft the same amount.
(Figure 2)
2. Repeat the procedure to the other driveline
half. Remove all burrs and cuttings.

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.
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: 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 over the large shaft of the gearbox and secure it with the two bolts, lockwashers
and nuts.
NOTE: Please refer to the drawings (Figures B through D on page 28) 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 5/16" x 3/4" 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.

Instructions - Post Hole Digger
Preparation Procedure
• 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.
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
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.
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.
Pre-Operation Checklist
(Owner/Operator Responsibility)
____ Review and follow safety rules and safety signs on pages 5 through 13.
____ 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.
18
Operation - Post Hole Digger
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 ­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 engaging the PTO.
• Increase the speed as required so dirt is conveyed from the hole. Refer to Owner’s Manual
for suggestions on PTO speed.
• Under no circumstances should the PTO be run in ­excess of 540 RPM.
• 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,
MAINTENANCE, AND STORAGE OF THIS EQUIPMENT BE AWARE, ­CONCERNED, PRUDENT, AND
PROPERLY TRAINED IN ­SAFETY.
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.
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.
19
Operation - Post Hole Digger
Operation - Continued
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.
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.
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.
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.
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.
A Grade 2 (5/16" x 2-1/2") shear bolt is included with your post hole digger. If the shear bolt
shears, replace only with a soft, Grade 2 shear bolt. DO NOT USE A HARD SHEAR BOLT! Use of
a hard shear bolt could result in damage to the gearbox or other post hole digger parts and voids
any warranty.
Do not run the digger while transporting, as damage to the PTO shaft could occur.
DO NOT LET THE DIGGER DIG SO DEEP THAT THE PTO SHAFT IS RUNNING IN THE DIRT.
Warning
Remain on the tractor seat while operating the post
hole digger. Assisting the machine by hand can result in
possible injury or death.
NOTE: Be sure auger is completely retracted from the hole before attempting to move the tractor.
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).
20
Operation - Post Hole Digger
Operation - Continued
Cutting edges and center point are replaceable. They should be sharpened or replaced
when worn. In hard ­digging conditions, a fishtail type center point is more aggressive and is
recommended.
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 it is running more than six (6) inches above the ground.
NOTE: If you have a rocky or large root soil condition, it is recommended that an industrial 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.
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.
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
screwing 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 attempt to free the auger while the PTO is
connected. Disconnect the PTO driveline from the tractor
before attempting to free the auger.
Caution
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. Check your telephone book for
calling instructions. Be sure post hole digger operator is
properly informed. WHEN IN DOUBT, DO NOT DIG!
NOTE: Never exceed the recommended auger ­capacity of the post hole digger. The Model 150
heavy duty digger is designed for use with augers up to 12-inch diameter. Use of an incorrect
auger or auger extension can cause equipment damage, loss of operator control and personal
injury.
21
Transporting - Post Hole Digger
Transporting
Pay particular close attention to the Safety Messages regarding transport. Avoid unnecessary
injuries and equipment damage by exercising cautious, conscientious travel procedures.
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
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.
DO NOT OPERATE PTO DURING TRANSPORT.
Raise the post hole digger as high as possible for ­transporting.
Select a safe ground travel speed when transporting from one area to another. When traveling on
roadways, transport in such a way that faster moving vehicles may pass you safely.
When traveling over rough or hilly terrain or when making turns, slow down and use extra care.
Read all safety warnings in the front of the manual.
22
Maintenance - Post Hole Digger
Maintenance
The information in this section is written for operators who possess basic mechanical skills.
Should you need help, your dealer has trained service technicians ­available. For your protection,
read and follow all safety information in this manual.
Warning
1. Lower post hole digger to ground or block ­securely,
turn tractor engine off, remove key and disconnect PTO
driveline from tractor PTO before performing any service or
maintenance.
2. 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.
3. Keep all persons away from operator control area while
performing adjustments, service or ­maintenance.
Routine Maintenance
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.
3. Grease the PTO shaft daily.
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.
Lubrication Information
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.

23
Maintenance - Post Hole Digger
At The End Of The Season:
1. Drain and change the oil in your gearbox.
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.
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.
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.
Removing Digger From Tractor
Post hole diggers when off the tractor, can be an ­awkward piece of equipment to handle. Be
careful not to pinch hands and fingers in the various hinge points of the digger.
Optional Parking Stand
The parking stand kit has two removable legs that go into sockets on a plate bolted to the
gearbox. The two legs and the auger form a tripod which will support the post hole digger when
removed from the tractor. Order optional parking stand #102160.
Post Hole Digger Options
1. 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 #170705.
2. Hydraulic Down Force Kit: For tough, hard soil conditions. This will allow operator to put 300400 lbs. of down force on the auger to force cutting edges into tough or hard ground. Tractor
must have auxiliary hydraulic outlet. Order part #170810 for Model 150 Post Hole Diggers.
3. Parking Stand Kit: This 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
#102160.

Troubleshooting - Post Hole Digger
Troubleshooting
Problem
Possible Solutions
Auger will not dig
1. Shear bolt sheared — install new shearbolt.
2. Teeth dull — sharpen or replace.
3. Ground too dry and hard — order optional down force kit, or wait until it
rains. (May have to replace center point.)
4. Auger turning too fast and bouncing — reduce speed.
5. Tall grass has wrapped around auger teeth — remove.
6. Auger encountering rocks, roots, or other obstruction — lift auger from hole
and inspect.
7. Auger teeth improperly positioned — see operator’s manual for proper
tooth pattern.
Auger digs so far,
but will not dig
deeper
1. See solutions for above.
2. PTO assembly “bottoms out,” not allowing digger to lower — remove auger
from digger and lower digger. Gearbox should lower to the ground; if not,
PTO ­driveline assembly may need to be shortened.
3. PTO driveline interferes with swinging drawbar — swing drawbar out of the
way or remove.
4. Tractor hydraulic system may be faulty — consult tractor dealer.
5. Soil could have hardpan layer 6"-10" below surface — use optional down
force kit (see list of optional ­equipment).
Post hole
digger sways
side to side
1. No sway bars or sway blocks on tractor — add same.
Bent auger flighting
or bent auger
1. Tractor moved while auger was turning in hole — always set brakes on
tractor and make sure it is out of gear.
2. Lift arms not adjusted evenly — adjust lift arms.
3. Post hole digger is mounted with excessive looseness in the hitch
connecting points — use proper size pins or bushings.
2. Operator moved tractor with auger in hole to try and straighten a hole being
dug at an angle.
3. Auger is encountering rocks or roots or other foreign objects — remove
object from hole or change location.
4. Outer edge of auger flighting is bending due to contact with rocks or roots
— use industrial duty auger with thicker flighting.
5. Shear bolt has been replaced with harder bolt — replace with Grade 2 bolt
per instructions.
Auger screws itself
into the ground
1. Operator did NOT ease 3-pt. hitch to ground slowly.
2. Faulty 3-pt. hitch hydraulic system on tractor.
3. Draft control is not in OFF position.
4. Tractor is too small to handle digger.
25
Troubleshooting - Post Hole Digger
Troubleshooting - continued
Excessive vibration
1. PTO driveline bearing cross is worn — replace.
PTO driveline
assembly comes
off input shaft of
gearbox when shear
bolt is sheared.
1. Roll pin missing in yoke at gearbox input shaft. Install roll pin as per
instructions.
PTO driveline failure
1. Operator raising post hole digger too high above ground when PTO is
engaged — causes excessive PTO joint operating angle.
Warning: this is a dangerous safety hazard, Correct immediately!
2. PTO is engaged while moving between holes. (Auger swings, which causes
excessive PTO joint operating angle.)
3. Improper use of a hard shearbolt — use Grade 2 bolt per instructions.
4. Driveline has not been properly lubricated.
5. Engaging tractor PTO with engine at high rpm.
6. Digging holes too deep so that PTO driveline contacts ground.
7. Operating at high rpm.
8. Use of auger extension can require post hole digger to be lifted high, which
can cause excessive PTO joint operating angle.
9. Tractor is a “low profile model” (one that is low to the ground). Due to
the low height of the tractor, the digger must be raised higher to have the
bottom of the auger clear the ground. Generally, low profile model tractors
can only use 30 inch long augers (standard auger length is 42"). Use a
different tractor or purchase 30" long augers.
Tractor stalls
1. Auger is encountering rocks or roots or other foreign object — remove
object or change hole location.
2. Tractor idle is not set correctly — tune tractor engine. PTO driveline
interferes with swinging drawbar — swing drawbar out of the way or
remove.
Gearbox failure
1. No oil in gearbox.
2. Oil not changed per instructions.
3. Shear bolt has been replaced with a harder bolt — replace with Grade 2 per
instructions.
4. Bent output shaft is due to operator moving tractor when auger is in hole.
Gearbox overheating
1. Low on lubricant — fill to proper level.
2. Improper type lubricant — replace with proper lubricant.
Auger bolts shear on
gearbox output shaft
1. Shearbolt on input shaft has been replaced with a harder bolt — replace
with Grade 2 bolt as per instructions.
Pto driveline “galls”
or “friction welds”
to input shaft of
gearbox
1. No lubrication on input shaft of gearbox to allow yoke of PTO driveline to
turn freely on input shaft when shear bolt is sheared. Always keep input
shaft greased.
26
2. Implement end yoke and gearbox input pinion may have to be replaced

Down Force Kit Instructions
Kit #170810 DFK-50 - (For Model 150 Post Hole Digger)
ATTENTION! Tractor must have auxiliary hydraulic outlet
to operate this hydraulic down pressure kit.
If your tractor does not have this outlet, check with your tractor dealer.
Installation
1. Refer to the parts illustration and install the Down Force Kit parts as shown. The pin
attaching the boom to the yoke is replaced by a 3/4- 10 NC x 6" lg. hex head bolt and lock
nut.
2. Use a good grade hydraulic thread sealant and install the hydraulic components. Do not
use Teflon tape!
3. Install the hydraulic cylinder and boom clamp. The cylinder rod should be retracted and
the boom clamp installed loosely so that it can slip on the boom. Raise the Post Hole
Digger to its full up position. Now ­tighten the boom clamp bolts to 300 ft. lbs. torque. It
may be necessary to retighten the clamp bolts after initial use to keep the clamp from
slipping.
4. Connect the pressure hose (item #15) to one of the tractor remote outlets.
5. Connect the return hose (item # 16) directly to the ­tractor hydraulic reservoir fill opening.
NOTE: DO NOT CONNECT THE RETURN HOSE TO A REMOTE OUTLET. The remote outlet
valve ports are blocked in the neutral position and will damage the hydraulic cylinder or
other parts when the boom is raised.
Operation
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.
The boom can be raised in the normal manner without relieving the down force cylinder
pressure.
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.
