Page 7: Assembly Instructions
REPAIR AND MAINTENANCE SAFETY ALWAYS perform maintenance operations such as lubrication, adjustments or repairs on the post hole digger with the tractor engine off, the PTO drive disengaged and the auger point resting on the ground. ALWAYS use the correct shear bolt (SAE Grade 2). NEVER use or replace the shear bolt with one that is longer than the one specified in the manual (3/18”...
Page 8 SET-UP INSTRUCTIONS The digger is shipped partially assembled. Assembly will be easier if the components are aligned and loosely assembled before tightening hardware. Select a suitable working area. Uncrate parts boxes and lay out parts and hardware to make location easy. Refer to illustrations, accompanying text, parts lists and exploded view drawings.
Page 9 GEARBOX PREPARATION AND INSTALLATION 1. Place gearbox upside down on a level surface with the output shaft facing up. 2. Place the output shaft guard onto the gear box, aligning the two bolt holes with the holes on the gear box. 3.
Page 10 INSTALL DRIVELINE 1. Clean input shaft on gearbox and smooth bore of driveline yoke. Remove any foreign material or paint. Lightly file any nicks or dents. 2. Grease the input shaft of the gearbox. This reduces the chance of the driveline galling the shaft if the shear bolt should fail.
Page 11 Shorten Driveline (If Required) 1. Remove driveline from gearbox shaft and tractor PTO. 2. Lower digger (with auger removed) until the input shaft of gearbox is in line with the PTO shaft of the tractor. This is the shortest distance required for the driveline. 3.
Page 12 2. Place the cutoff portion of the shield against the end of the shaft and use it as a guide. Mark and cut the shaft. Figure 7. Cut Shaft to Length 3. Repeat steps for other drive half. 4. File and clean-cut ends of the both drive halves. 5.
Page 13: Operating Instructions
OPERATING INSTRUCTIONS The post hole digger and its individual components are NOT to be used for anything other than their intended use. 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.
Page 14 ◼ Keep digger under control by running PTO at slowest speed possible (no faster than half- throttle in 540 RPM range). CAUTION ◼ Always wear relatively tight and belted clothing to avoid getting caught in moving parts. Wear sturdy, rough-soled work shoes and protective equipment for eyes, hair, hands, hearing, and head;...
Page 15 PRE-OPERATION CHECKLIST * Review and follow all safety rules and safety decal instructions on pages 4 through 7. * Check that all safety decals are installed and in good condition. Replace if damaged. * Check that all shields and guards are properly installed and in good condition. Replace if damaged. * Consult local utilities before digging.
Page 16 3. Do not allow anyone to stand within 25 ft of the auger during operation. 4. Lower auger point slowly to the ground with the PTO disengaged. 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.
Page 17 SHEAR BOLT REPLACEMENT WARNING ◼ Never replace shear bolt or auger retaining bolt with a different length, or grade. Always use a SAE grade 2 bolt as a replacement. 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.
Page 18 clearance for the implement to swing when turning. Raise the implement as high as possible for transporting. REMOVE DIGGER FROM TRACTOR When off the tractor, post hole diggers 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.
Page 19: Owner Service
OWNER SERVICE The information in this section is written for operators who possess basic mechanical skills. 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.
Page 20 LUBRICATION INFORMATION WARNING ◼ Failure to maintain proper lubrication can result in damage to U-joints, gearbox, tractor PTO and/or driveline which can cause serious injury or death. CAUTION ◼ When lubricating telescoping PTO drives, keep fingers out of shield access slots to prevent injury.
Page 21 wear faster than inner cutting edges; switching teeth will even wear. 8. Store implement in clean and dry location. REMOVE DIGGER FROM TRACTOR When off the tractor, post hole diggers 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.
Page 22 REPLACE CUTTING EDGE Cutting edges and center points are replaceable. They should be sharpened or replaced when worn. 1. Remove carriage bolt (4), lock washer (5), and hex nut (6) holding cutting tooth to the auger. 2. Replace or sharpen cutting tooth. Install carriage bolt, lock washer, and hex nut previously removed. 3.
Page 23: Troubleshooting
● Replace any safety decals that are missing or not readable. TROUBLESHOOTING PROBLEM POSSIBLE CAUSES & SOLUTION Shear bolt sheared – install new shear bolt. Auger will not dig Teeth dull – sharpen or replace. Ground too dry and hard – order optional down force kit, or wait until it rains.
Page 24 gearbox when shear bolt is sheared Install set screw as per driveline installation instructions. THIS IS A DANGEROUS SAFETY HAZARD, CORRECT IMMEDIATELY! PROBLEM POSSIBLE CAUSES & SOLUTION Auger digs so far, but will not dig deeper See solutions for above. PTO assembly “bottoms out,”...
Page 25 when shear bolt is sheared. Always keep input shaft greased. PROBLEM POSSIBLE CAUSES & SOLUTION Gearbox failure No oil in gearbox. Oil not changed per instructions. Shear bolt has been replaced with a harder bolt – replace with Grade 2 per instructions. Bent output shaft is due to operator moving tractor when auger is in hole.
