SAFETY RULES ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED! 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 an operator’s single careless act. In addition to the design and configuration of equipment, hazard control and accident prevention are dependent upon the awareness, concern, judgement, and proper training of personnel involved in the operation, transport, maintenance, and storage of equipment.
SAFETY RULES ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED! Do not put digger into service unless all shields and guards are in place and in good condition. Replace if damaged. Keep bystanders away from equipment. Do not operate or transport equipment while under the influence of alcohol or drugs. Operate only in daylight or good artificial light. Never aim auger point with hands on auger, gearbox or boom. To place auger point use skid steer arms.
SAFETY RULES ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED! (Safety Rules continued from previous page) Never replace shear bolt or auger retaining bolt with a different length, or grade. Always use a grade 2 bolt as a replacement. Look down and to the rear and make sure area is clear before operating in reverse. Do not stop, start, or change directions suddenly on slopes. Always wear relatively tight and belted clothing to avoid getting caught in moving parts.

OPERATION The operator is responsible for the safe operation of the equipment. The operator must be properly trained. Operators should be familiar with the equipment, the tractor, and all safety practices before starting operation. Read the safety rules and safety decals on page 4 to page 8. Post hole diggers are designed for one-man operation. You must always dig holes while sitting in the tractor seat.
Use stabilizer bars, adjustable sway chains, or sway blocks on your tractor lift arms to keep the post hole digger from swaying side to side. Adjust as tightly as practical for best performance. Remove or place tractor drawbar in storage position. dirt breaking up and being carried to the top by the auger flighting. IMPORTANT ■ Post hole digger gearboxes are shipped without lubrication. Gearboxes must be serviced with 90W gear lube before operation.
If you have difficulty penetrating hard ground, refer to the Troubleshooting section in this manual for suggestions. DOWN FORCE KIT OPERATION (OPTIONAL) IMPORTANT ■ Do not connect RETURN hose to a remote outlet. Remote outlet ports are blocked in the neutral position and will damage the hydraulic cylinder when boom is raised. 1. Lower post hole digger using the 3-point arms and allow auger to dig. 2. If down force is required, slowly apply down force using the control lever for the remote outlet.
SHEAR BOLT REPLACEMENT WARNING Never replace shear bolt or auger retaining bolt with a different length, or grade. Always use a grade 2 bolt as a replacement. Remove input guard from around driveline. Shear bolts are important for both safety and preventing damage to the digger. Their intended function is to break when too much force is applied. Always replace shear bolts at the gearbox input and output shafts with manufacturer's part or one of the same size, length and Grade 2 specification.
OWNER SERVICE The information in this section is written for operators who possess basic mechanical skills. If you need help, your dealer has trained service technicians available. For your protection, read and follow all safety information in this manual. WARNING Before performing any service or maintenance, lower digger to ground or block securely, turn off tractor engine, remove key, and disconnect driveline from tractor PTO. NEVER GO UNDERNEATH EQUIPMENT.
Daily lubrication of the PTO slip joint is necessary. Failure to maintain proper lubrication can result in damage to U-joints, gearbox, tractor PTO and/or driveline. STORAGE 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.
CLEAN POST HOLE DIGGER 1. Be careful when spraying near scratched or torn safety decals or near edges of decals as water spray can peel decal off surface. After Each Use ● Remove large debris such as clumps of dirt, grass, crop residue, etc. from machine. ● Inspect machine and replace worn or damaged parts. ● Replace any safety decals that are missing or not readable. 2. Be careful when spraying near chipped or scratched paint as water spray can lift paint. 3.
TROUBLESHOOTING PROBLEM Auger will not dig POSSIBLE CAUSES & SOLUTION Shear bolt sheared – install new shear bolt. Teeth dull – sharpen or replace. Ground too dry and hard – order optional down force kit, or wait until it rains. Auger turning too fast and bouncing – reduce speed. Tall grass has wrapped around auger teeth – remove grass. Auger encountering rocks, roots, or other obstruction – lift auger from hole and inspect.
TROUBLESHOOTING PROBLEM PTO driveline failure POSSIBLE CAUSES & SOLUTION Operator raising post hole digger too high above ground when PTO is engaged – causes excessive PTO joint operating angle. PTO is engaged while moving between holes. (Auger swings, which causes excessive PTO joint operating angle.) Improper use of a hard shear bolt – use Grade 2 bolt per instructions. Driveline has not been properly lubricated. Engaging tractor PTO with engine at high rpm.
ASSEMBLY INSTRUCTIONS WARNING 2. Connect A-frame and cross to the tractor 3-point arms. Keep hands, feet, hair, and clothing away from equipment while engine is running.

Check the driveline to see if it separates, binds, or bottoms out. NOTE: Gearbox should lower to the ground. If not, change hole location between A-frame and boom or see if driveline is bottoming out. If driveline is bottoming out it will need to be shortened. Shorten Driveline (If Required) 15. 26. 28. 29. 30.

Hang the driveline from the hook to help prevent dirt and debris from accumulating in the locking collar on the driveline PTO yoke. INSTALL DOWN FORCE KIT (OPTIONAL) Install Pivot Plates and Cylinder 1. Remove cap screw that connects A-frame bars to the post hole digger boom. 2.
IMPORTANT Install Cylinder Clamps 1. Make sure cylinder (11) is retracted. 2. Place cylinder clamps (6, top) and (7, bottom) around boom, Figure 12. 3. Loosely secure to boom using two cap screws (8), lock washers (9), and hex nuts (10). Clamp should slip on boom. ■ Do not connect RETURN hose to a remote outlet. Remote outlet ports are blocked in the neutral position and will damage the hydraulic cylinder when boom is raised. 4. Attach cylinder to top clamp using cap screw (12) and lock nut (13). 5.
