Page 2 To the Owner/Operator/Dealer 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.

Page 6: General Safety Instructions And Practices
SAFETY GENERAL SAFETY INSTRUCTIONS AND PRACTICES A careful operator is the best operator. Safety is of primary importance to the manufacturer and should be to the owner/operator. Most accidents can be avoided by being aware of your equipment, your surroundings, and observing certain precautions.
Page 7: Operator Safety Instructions And Practices
SAFETY OPERATOR SAFETY INSTRUCTIONS AND PRACTICES Never crawl under a raised Implement supported solely by the Power Unit boom. Release of the control lever or mechanical failure will result in the Implement falling and possible injury or death. Always securely block up the Implement before crawling underneath to perform repairs and service.
Page 8 SAFETY KEEP AWAY FROM ROTATING ELEMENTS to prevent entanglement and possible serious injury or death. (SPHD-2) str 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.
Page 9: Equipment Operation Safety Instructions And Practices
SAFETY NEVER use drugs or alcohol immediately before or while operating the Power Unit and Implement. Drugs and alcohol will affect an operator’s alertness and coordination and therefore affect the operator’s ability to operate the equipment safely. Before operating the Power Unit or Implement, an operator on prescription or over-the-counter medication must consult a medical professional regarding any side effects of the medication that would hinder their ability to operate the Equipment safely.
Page 10 SAFETY Operate this Equipment only with a Power Unit equipped with an approved operator Roll-Over Protective Structure (ROPS). Always wear seat belts. Serious injury or even death could result from falling off the Power Unit-- particularly during a turnover when the operator could be pinned under the Operator Protective Structure.
Page 11: Connecting Or Disconnecting Safety Instructions And Practices
SAFETY Do not operate this Equipment with hydraulic oil or fuel leaking. Oil and fuel are explosive and their presence could present a hazard. Do not check for leaks with your hand! High-pressure oil streams from breaks in the line could penetrate the skin and cause tissue damage including gangrene.
Page 12: Maintenance And Safety Instructions & Practices
SAFETY Use extreme care when the Auger is in the transport position to prevent contact between the Auger and bystanders or solid objects. Contact with the Auger could cause serious damage, injury, or death. Never operate the Auger while in the transport position. (SPHD-12) str Transport only at safe speeds.
Page 13 SAFETY Always maintain the safety signs in good readable condition. If the safety signs are missing, damaged, or unreadable, obtain and install replacement safety signs immediately. (SG-5)str Do not modify or alter this Implement. Do not permit anyone to modify or alter this Implement, any of its components or any Implement function.
Page 14: Parts Information
These parts are made and tested to Bush Hog specifications. Non-genuine "will fit" parts do not consistently meet these specifications. The use of “will fit” parts may reduce equipment performance, void warranties, and present a safety hazard. Use genuine Bush Hog parts for economy and safety.

Page 51: Transporting On Public Roadways
OPERATION 9.1 Transporting on Public Roadways Extreme caution should be used when transporting the power unit and implement on public roadways. The power unit must be equipped with all required safety warning features including a SMV emblem and flashing warning lights to alert drivers of the power unit’s presence. Remember that roadways are primarily designed for automotive drivers and most drivers will not be looking out for you, therefore, you must look out for them.
Page 52: Hauling The Power Unit And Implement
OPERATION When operating public roads, have consideration for other road users. Pull to the side of the road occasionally to allow all following traffic to pass. Do not exceed the legal speed limit set in your country for agricultural power units.
Page 53 OPERATION Use adequately sized and rated trailers and equipment to transport the tractor and implement. Consult an authorized dealer to determine the proper equipment required. Using adequately sized chains, heavy duty straps, cables and/or binders, securely tie down both the front and rear of the tractor utilizing the proper tie down locations as specified by the tractor manufacturer.
Page 54: Troubleshooting Guide
OPERATION 10. TROUBLESHOOTING GUIDE Problem Possible Cause Remedy Gearbox Leaking Damaged oil seal. Replace seal. No oil seal. Install oil seal. Oil too light. Use EP140. Oil seal race is rough. Replace shaft or replace race. Oil seal not sealing in the housing. Replace seal or use sealant on O.D.
Page 56 MAINTENANCE Before operating the Post Hole Digger, make sure it is properly lubricated and thoroughly inspected. Only a minimum of time and effort is required to regularly lubricate and maintain this machine to provide long life and trouble free operation. LUBRICATION INFORMATION The drilling machine must be properly lubricated to achieve the best operation and longest life.
Page 57: Auger Maintenance
MAINTENANCE AUGER MAINTENANCE Inspect auger to loose, worn, broken and missing cutting teeth and points. Worn teeth and points can greatly affect auger penetration and greatly reduce auger life expectancy. Always keep spare teeth and points on hand. Some digging may require inspecting teeth and point condition more frequently. On rock augers, inspect the wear of hardfacing.
Page 58: Hydraulic Lines, Couplers & Adapters
MAINTENANCE HYDRAULIC LINES, COUPLERS & ADAPTERS Keep all hoses and adapters tight. Repair any leaks immediately. Do not over-tighten hose end fittings. Tighten to specifications only. (See Chart below) PROPER TORQUE FOR FASTENERS The chart lists the correct tightening torque for fasteners. When bolts are to be tightened or replaced, refer to this chart to determine the grade of bolts and the proper torque except when specific torque values are assigned in manual text.
