 DO NOT operate higher than 540 RPM.

 Keep hands, feet, clothing, and hair away from moving parts.

 DO NOT operate without the driveline securely attached at both ends.

 DO NOT operate without the driveline shields that turn freely on the driveline.

Assembly Instructions

Note: For safety, two people are recommended for the assembly of the digger.

1. Place palletized digger on level ground and cut the shipping bands.

Page 7 of 22

2. Attach the boom to the top link mounting bracket on the tractor using a top link pin and a linch

pin through the hole at the bottom of the boom.

3. Connect the A frame to the tractor’s 3-point lift arms using the 7/8” pull pins with nut and lock

washer.

4. Remove the top link pin from the A frame. Attach the A frame to the boom after selecting the

desired hole (for angle adjustment), using the 2-3/4” top link and the 7/16” linch pin.

5. Raise the 3-point lift arms high enough to allow room for the auger installation.

Page 8 of 22

6. Using a 9/16” wrench, remove the shear bolt. Use a hex screwdriver to loosen the jam nut off

the screw enough to clear the internal bore of the PTO shaft.

7. Attach the auger to the output shaft on the bottom of the gear box using the 1/2” x 3” hex cap

grade 5 screws, 1/2” lock washers, and 1/2” hex nuts. Tighten the nuts using the provided

ratchet holes, if needed.

Page 9 of 22

8. Attach the driveline to the gear box input shaft using the 5/16” grade 5 hex cap screw, the

5/16” lock washer, and the 5/16” NC hex nut. Tighten the hex nut. Insert the 1/4” x 3/8” set

screw from the hardware kit in the hole on the yoke that aligns with the 3/16” groove on the

gear box input shaft. Tighten.

Attention

The 3/8” hex cap screw provides shear protection. Use a grade 2 3” bolt (not provided) only to avoid

damage to the gear box or auger.

Important

The universal joint should be greased with a good grade chassis lube every week. At the beginning of

each season, grease the sliding drive shaft members with a moly grease. All diggers are equipped

with quick-detach universal joints on the PTO end for a 1-3/8” splined shaft.

9. Attach the tractor end of the driveline to the tractor PTO shaft. Push in the spring-loaded pin

in the splined yoke and slip it on the splined PTO shaft of the tractor. Release the pin and

push in until it locks securely in place. Note: It will be necessary to obtain a 1-1/8” to 1-3/8”

sleeve spline adapter if your tractor PTO shaft has a 1-1/8” spline.

10. Attach and secure both chains on the driveline to the boom.

Note: When the 7/8” diameter pull pins in the A frame are too small for the holes in the lift arms,

bushings should be used to obtain a proper fit.

Important:

The gearbox is shipped without lubricant. Refer to the next section before using the digger.

Always perform maintenance operations with the tractor engine off, the PTO drive disengaged, and

the auger point resting on the ground.

Page 10 of 22

Before Using the Digger

IMPORTANT

The digger was shipped without oil in the gearboxes. Oil must be added to the gearbox before

operating.

Note: Fill the gearbox using gear oil (type 80W-90 lubricant) and fill to the oil level plug. Check the

gear box every fifty hours of use to assure adequate lubrication.

Note: Check all nuts and bolts for tightness. Stabilizers should be kept tight to avoid the side sway of

the digger.

Adding and Changing Gearbox Oil

1. Using a 7/8” wrench, remove the 1/2” vented pipe plug located on front of the gearbox above the

PTO shaft.

2. Remove the check plug located at back of the gearbox.

3. Fill the front of the gearbox with gear oil until it begins to overflow from the check plug hole in

the rear.

Page 11 of 22

⚠CAUTION

DO NOT overfill the gearbox. This could cause damage to the oil seals and

can cause permanent damage to the gearbox (which is not covered under

warranty).

4. Replace and tighten the check plug.

5. Replace and tighten the 1/2” vented pipe plug and clean off any excess oil.

Attaching to the Tractor

Never stand between the tractor and the digger while backing up the tractor to the hitch.

Note: For safety, it’s recommended that two people attach the digger to the tractor.

1. Place the tractor and the digger on level ground and inspect for defects to make sure all

guards and shields are in place.

2. Set the digger in an upright position on the ground. While one person carefully balances the

digger, the other person attaches the boom to the top link mounting bracket and the A frame

to the lift arms on the tractor.

3. Raise the digger to allow enough room to install the auger. Attach the auger to the bottom of

the gearbox.

4. Attach the PTO driveline to the tractor and to the digger’s gearbox input shaft, and secure the

anti-rotation chains.

5. Determine if the PTO shaft needs to be shortened.

Page 12 of 22

Note: Due to the many variations in the tractor hitch points and distances between the equipment

gearbox input shaft and the tractor PTO output shafts, some combinations may require the PTO

shafts to be shortened, as described by the following steps.

6. Raise and lower the digger in order to locate the shortest distance between the equipment

gearbox, the input shaft, and the tractor PTO output shaft. With the digger is in the shortest

distance position, shut down the tractor, and secure the digger in position.

7. Pull apart the PTO shaft and attach the outer section to the tractor PTO output shaft.

Note: Be sure to pull on the PTO shaft section to ensure that the yoke is locked into place.

8. Place and hold the inner PTO shaft section next to the outer section and check to see if the

PTO shaft is too long. Each section should end approximately 3” short of reaching the u-joint

shield on the opposite section. If the shaft is too long, measure 3” back from each u-joint

shield and mark the other shaft section. Be sure to do this for both PTO shaft halves.

Note: Do not cut the PTO shaft sections at this time.

9. Raise the digger. Raise and lower the digger in order to locate the longest distance between

the equipment input shaft and the tractor PTO output shaft. With the digger in the longest

distance position, shut down the tractor and secure the digger in position.

10. As in step 5, hold the PTO shaft sections together and check for a minimum of 6” of overlap. If

the PTO shaft has been marked for cutting, the overlap is the distance measured between the

two marks. If the PTO shaft has less than a 6” overlap, do not use it. Contact your dealer for

a replacement.

Note: If the PTO shaft length is too long, refer to the Sizing the PTO Shaft section.

11. Apply any multi-purpose grease to the outside of the male (inner) PTO shaft section.

Assemble the PTO shaft and install on the digger and the tractor.

12. Pull on the tractor side of the PTO shaft yoke to be sure it has locked into place. Make certain

the PTO shaft shielding is in place and in good working condition.

13. The PTO shaft shield has a non-rotating design and must be secured prior to equipment use.

Attach the chains on the yoke shield to a fixed object on the tractor and the equipment. This

will prevent the PTO shield from rotating (see the top of page 10).

Before Each Use

Safety is a primary concern in the design and manufacturing of our product. Unfortunately, our efforts

to provide safe equipment can be wiped out by a single careless act of an operator or bystander.

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 this equipment.

It has been said, “The best safety device is an informed, careful operator.” We ask you to be that kind

of operator. It is the operator’s responsibility to read, understand, and follow all safety and operating

instructions in this manual. Accidents can be avoided.

Working with unfamiliar equipment can lead to careless injuries. Read this manual and your tractor’s

manual, before assembling or operating, to acquaint yourself with the machines. If this machine is

used by someone other than the owner, or is loaned or rented, it is the owner’s responsibility to make

certain that this manual be available to the operator prior to operating. All users must:

Page 13 of 22

1. Read and understand the Owner’s Manual.

2. Be instructed in safe and proper use.

Know your controls and how to stop the tractor, the engine, and the digger quickly in an emergency.

To understand how to do this, read this manual and your tractor’s manual.

Train all new personnel and review instructions frequently with existing workers. Be certain only a

properly trained and physically able person will operate the machinery. 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. If the

elderly are assisting with farm work, their physical limitations need to be recognized and

accommodated.

Preparation

Never operate the tractor and digger until you have read and completely understood this manual, the

tractor Owner’s Manual, and each of the safety messages found on the safety signs on the tractor and

digger.

Personal protection equipment including hard hat, safety goggles, safety shoes, and gloves are

recommended during assembly, installation, operation, adjustment, maintenance, repairing, removal,

or movement of the implement. Do not allow long hair, loose fitting clothing, or jewelry to be around

equipment.

Prolonged exposure to loud noise may cause permanent hearing loss! Tractors with or without

diggers 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 65

dB. Noise over 65 dB on a long-term basis can cause severe hearing loss. Long term noise over 65

dB adjacent to the operator, may cause permanent, and total hearing loss.

Note: Hearing loss from loud noise (tractors, chain saws, radios, and other such sources close to the

ear) is cumulative over a lifetime, without hope of natural recovery.

 Operate the digger only with a tractor equipped with an approved Roll Over Protection System

(ROPS). Always wear your seat belt. Serious injury or even death could result from falling off the

tractor — particularly during a turnover when the operator could be pinned under the ROPS or the

tractor.

 Clear the digging area of stones, branches, or other debris that might be thrown or entangled in

the digger, causing injury or damage.

 Operate only in daylight or good artificial light.

 Ensure that the digger is properly mounted, adjusted, and in good operating condition.

 Ensure that all safety shielding and safety signs are properly installed and in good condition.

Operating Instructions

Starting and Stopping

Check the tractor master shield over the PTO stub shaft. Make sure it is in good condition and

fastened securely to the tractor. Purchase a new shield if the old shield is damaged or missing.

All tractors that are not equipped with “live” PTO need to be equipped with an over-running PTO

clutch (available through most farm equipment stores).

Page 14 of 22

Note: The addition of an over-running PTO clutch may change the length of the PTO driveline

required. Pay extra attention to the instructions on the PTO Driveline installation. Be sure that the

driveline system guarding is adequate.

The digger’s operating power is supplied from the tractor PTO. Refer to your tractor manual for PTO

engagement and disengagement instructions. In the case of an emergency, know how to quickly stop

the tractor and the digger.

When engaging the PTO, the engine RPM should always be at idle speed. Once engaged and ready

to start digging, raise the PTO speed to 540 RPM and increase the speed as the auger drills deeper.

Hazards and Obstructions

The use of this equipment is subject to certain hazards that cannot be solely protected by the

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 that you do not understand, ask your supervisor or dealer to explain it to you.

Most accidents occur because of neglect or carelessness. Keep all helpers and bystanders at least

several hundred feet from an operating digger. Only properly trained people should operate this

machine.

When the machine is operated in populated areas where thrown objects could injure persons or

property, operation must be stopped when anyone comes within several hundred feet.

The majority of farm equipment accidents involve entanglement on the driveline, injury of bystanders

by the objects thrown by the rotating auger, and operators being knocked off the tractor by low

hanging limbs and being injured by the equipment. Accidents are most likely to occur with machines

that are loaned or rented to someone who has not read the Owner’s Manual and is not familiar with

the digger.

The digger is only designed for use on tractors with the PTO turning at 540 RPM.

Install and secure all guards and shields before starting or operating. The digger, driveline guards,

and tractor shields should be used and maintained in good working condition. They should be

inspected carefully, at least daily, for missing or broken chain links, shields, or guards. (Worn items

must be replaced at once to reduce the possibility of injury.)

Disengage the PTO shaft and place the transmission in neutral before attempting to start the engine.

Many varied objects, such as wire, cable, rope, or chains, can become entangled in the operating

parts of the digger. These items could then swing outside the housing at greater velocities than the

auger. Such a situation is extremely hazardous. Inspect the digging area for such objects before

digging. Remove any of these objects from the site.

Never allow the auger to contact such items. Never assume an area is clear. Always Check!

Always stop the tractor, disengage the PTO, set the brake, shut off the tractor engine, remove the

ignition key, lower the implement to the ground, and allow rotating pieces to come to a complete stop

before dismounting the tractor. Never leave the equipment unattended with the tractor running.

Never place hands or feet under the digger with the tractor engine running or before you are sure all

motion has ended. Stay clear of all moving parts.

Do not reach or place any part of your body under the equipment until it is properly secured.

Do not allow riders on the digger or the tractor at any time. There is no safe place for riders on this

equipment.

Page 15 of 22

Do not operate unless all personnel, livestock, and pets are several hundred feet away to prevent

injury by thrown objects.

Never operate the tractor and the digger under trees with low hanging limbs. Operators can be

knocked off the tractor and hit by equipment.

The rotating parts of this machine have been designed and tested for rugged use. However, they

could fail upon impact with heavy, solid objects such as steel guardrails and concrete abutment. Such

impact could cause the broken objects to be thrown outward at very high velocities. To reduce the

possibility of property damage, serious injury, or even death, never allow the auger to contact such

obstacles.

Stop the digger and the tractor immediately upon striking an obstruction. Turn the engine off, remove

the key, inspect the equipment, and repair any damage before resuming operation.

Maneuvering

Stay alert for uneven terrain, holes, rocks, roots, and other hidden hazards. Keep away from drop-offs

and hazards that could cause a roll over. Use extreme care and maintain minimum ground speed

when operating on hillsides, over rough ground, and close to ditches or fences. Be careful and slow

down when turning sharp corners and changing directions on slopes. Do not start or stop suddenly on

slopes. Avoid operation on steep slopes. In extremely uneven terrain, rear wheels weights, front

tractor weight, and/or tire ballasts should be used to improve stability.

Pass the digger diagonally through sharp dips and avoid sharp drops to prevent ‘hanging up’ the

tractor and the digger. Practice will improve your skills in maneuvering on rough terrain. Always travel

parallel to the slope, never cutting through. Always check the tractor manual for proper use on slopes.

When using this equipment, a minimum 20% of tractor and equipment weight must be on the tractor’s

front wheels. Without this weight, the tractor could tip over, causing personal injury or death. The

weight may be attained with a front-end loader, front wheel weights, ballast in the tires, or front tractor

weights. When attaining a minimum 20% of tractor and equipment weight on the front wheels, you

must not exceed the ROPS weight certification. Weigh the tractor and equipment. Do not guess or

estimate!

Transportation

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 lighting and marking requirements.

At all times, when driving the tractor and equipment on the road or highway under 20 MPH (32 KPH),

use flashing amber warning lights and a slow moving vehicle (SMV) identification emblem. Do not

exceed 20 MPH (32 KPH). Reduce speed on rough roads and surfaces.

Plan your route to avoid heavy traffic.

Always install transport locks, pins, or brackets before transporting.

Do not drink and drive.

Be a safe and courteous driver. Always yield to oncoming traffic in all situations, including narrow

bridges, intersections, etc. Watch for traffic when operating near or crossing roadways.

Turn curves or go up or down hills only at a low speed and at a gradual steering angle. Make certain

that a least 20% of the tractor’s weight is on the front wheels to maintain safe steerage. Slow down on

rough or uneven surface. Always check the tractor manual for proper use on slopes.

Page 16 of 22

Use extreme care and maintain minimum ground clearance when operating close to ditches or fences.

Be careful when turning sharp corners.

After Each Use

Note: For safety, it’s recommended that two people detach the digger.

⚠CAUTION

To prevent personal injury caused by unexpected movement:

1. Park the machine on a level surface.

2. Engage the tractor parking brake and/or place the transmission in

park.

3. Disengage the PTO.

4. Shut off the tractor’s engine and remove the key.

Detaching from the Tractor

1. Remove the PTO driveline from the tractor and the digger gearbox.

⚠WARNING

Shut off the tractor’s engine before detaching the PTO driveline. An

entanglement in a rotating driveline can cause serious injury or death.

2. Adjust the digger to allow room for the auger removal. Remove the auger from the bottom of

the gearbox.

3. Lower the boom by using the lift arms on the tractor. Detach the boom from the top link

mounting bracket and lift the arms.

4. Carefully lay the digger on the ground in a secure position.

Cutting the PTO Shaft to Length

Note: Be sure to cut equal lengths of each PTO shaft section.

1. Clamp the end of the PTO shaft in a vice and cut off the shield where it’s marked (Figure A &

Figure B).

Page 17 of 22

2. Using the cut section of the shield as a guide, cut the same amount off the shaft.

3. Repeat steps 1 and 2 for the other PTO shaft section.

4. Use a file to deburr the PTO shafts. Clean up all chips, burrs, and filings from both ends of the

PTO shaft.

Maintenance

Good maintenance is your responsibility.

 Follow good shop practices.

 Keep your service area clean and dry.

 Be sure the electrical outlets and tools are properly grounded.

 Use adequate light for the job at hand.

 Make sure there is plenty of ventilation. Never operate the engine of the towing vehicle in a closed

building. The exhaust fumes may cause asphyxiation.

 Before working on this machine, disengage the PTO, shut off the engine, set the brakes, and

remove the ignition keys.

 Be certain all moving parts on the attachments have come to a complete stop before attempting

to perform maintenance.

 Never work under equipment unless it is securely supported.

 When performing any service or maintenance, always use personal protection devices such as

eye, hand, and hearing protectors.

 Frequently check the digger’s auger. It should be securely fastened and free of nicks and cracks.

Page 18 of 22

 Periodically tighten all bolts, nuts, and screws and check that all cotter pins are properly installed

to ensure the unit is in safe condition.

 When completing a maintenance or service function, make sure all safety shields and devices are

installed before placing the unit in service.

 After servicing, be sure all tools, parts, and service equipment are removed from the digger.

 Do not allow debris, grease, or oil, to build up on the digger.

 When 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 be responsible for injuries or damages caused by the use of

unapproved parts and/or accessories.

 A fire extinguisher and a first aid kit should be kept readily accessible while performing

maintenance on this equipment.

Troubleshooting

Always perform maintenance operations with the tractor engine off, the PTO drive disengaged, and

the auger point resting on the ground.

1. To remove the auger from the gear box output shaft, take out the two (2) 1/2” x 3-1/2” hex cap

screws.

2. To remove the drive shaft from the gear box input shaft, take out the shear pin bolt and the

1/4” set screw.

3. Check the oil level after every fifty hours of use. Use 80W- 90 lubricant and fill to the oil level

plug. All replacement lubricants should be of this type.

4. The universal joints should be greased with a good grade chassis lube every week. At the

beginning of each season, grease the sliding drive shaft members with moly grease.
