IMPORTANT SAFETY PRECAUTIONS This symbol is used to call attention to safety precautions that should be followed by the operator to avoid accidents. When you see this symbol, carefully read the message that follows and heed its advice. Failure to comply with safety precautions could result in serious bodily injury. 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 in the operation, transport, maintenance and storage of equipment. Lack of attention to safety can result in accident, personal injury, reduction of efficiency and worst of all—loss of life. Watch for safety hazards and correct deficiencies promptly. Use the following safety precautions as a general guide to safe operations when using this machine. Additional safety precautions are used throughout this manual for specific operating and maintenance proce-dures. Read this manual and review the safety precautions often until you know the limitations. 1. Read the Operator’s Manual. Failure to read the Operator’s Manual is considered a misuse of this equipment. 2. Become familiar with all the machine’s controls and all the caution, warning and danger decals affixed to the machine before attempting to start or operate. 3. Before starting or operating the machine, make a walk around inspection and check for obvious defects such as loose mounting bolts and damaged components. Correct any deficiency before starting. 4. Do not allow children to operate the cutter. Do not allow adults to operate it without proper instruction. 5. Do not carry passengers. 6. Keep the area of operation clear of all persons, particularly small children and pets. The operator should cease mowing whenever anyone comes within the operating area. 7. Clear the work area of objects which might be picked up and thrown. 8. Use a piece of cardboard or wood rather than hands to search for hydraulic leaks. Escaping hydraulic oil under pressure can penetrate skin. If fluid is injected into the skin, it must be surgically removed within a few hours by a doctor familiar with this form of injury or gangrene may result. 9. Do not operate without all guards and shields in place and in good condition. 10. Lower implement to ground, stop tractor engine, apply parking brake, and allow blades to completely stop before leaving the tractor. 11. Keep hands and feet away from blades. 12. This cutter is not to be operated along highways or in any area where people may be present unless all sides of the unit are enclosed by permanent bands, safety chains or other factory approved safety shields that are in good repair. 13. Wear personal protective equipment such as, but not limited to, protection for eyes, ears, feet, hands and head when operating or repairing the equipment. Do not wear loose clothing or jewelry that may catch on equipment moving parts. 14. When performing adjustments or maintenance on the cutter, first lower it to the ground or block it securely at a workable height. 15. Never stand between tractor and cutter while tractor is being backed to the cutter hitch. 16. Reduce speed when transporting cutter to avoid bouncing and momentary loss of steering. 17. Use tractor flashing warning lights, day or night, when transporting cutter on road or highways unless prohibited by law. 18. In the event that someone other than yourself will operate this equipment we firmly suggest that all SAFETY references be discussed prior to operation. 19. It is recommended that tractor be equipped with Rollover Protective System (ROPS) and seat belt be used in all mowing operations. 5

1-1 INTRODUCTION We are pleased to have you as a Bush Hog customer. Your RDTH Series Rotary Cutter has been carefully designed to give maximum service with minimum down time.This manual is provided to give you the necessary operating and maintenance instructions for keeping your rotary cutter in top operating condition. Please read this manual thor- oughly. Understand what each control is for and how to use it. Observe all safety precautions decaled on the machine and noted throughout the manual for safe operation of implement. If any assistance or additional information is needed, contact your authorized Bush Hog dealer. 1-2 DESCRIPTION The RDTH cutters (Figure 1-1) are grooming mow- ers intended for cutting lawns, golf courses, athletic fields, or any maintained area where a clean, uni- form finish is desired. Uplift blades form a suction during operation to lift the grass before cutting it. The caster wheel arrangement along with the floating lift linkage and optional front roller, all work together to give an even cut and minimize scalping. Power from the tractor is transmitted through a trian- gular, telescoping driveline to the 90 degree gearbox. It is then passed to the spindle housings by a single, B-section, Kevlar reinforced belt. Drivetrain protection is provided by belt slippage.

2-1 ATTACHING TO TRACTOR A. Attach to tractor Cat. I three point hitch as described in tractor operator’s manual. B. Raise and lower cutter to determine position with shortest distance between the tractor PTO shaft and gearbox input shaft. Shut down tractor leaving cutter in position of shortest distance. SECURELY BLOCK CUTTER IN POSITION. C. Pull driveline apart. Attach outer (female) section to tractor PTO shaft. Pull on driveline section to be sure yoke locks into place. SECTION II PREPARATION FOR USE D. Hold driveline sections parallel to each other to determine if too long. Each section should end approximately 3 inches (76mm) short of reaching universal joint shield on opposite section. If too long, measure 3 inches (76mm) back from universal joint shield and mark opposite section. (Figure 2-1). Do this for both sections. E. Raise and lower cutter to determine position with greatest distance between PTO shaft and gearbox input shaft. Shut down tractor leaving cutter in position of greatest distance. SECURELY BLOCK CUTTER IN POSITION. F. Hold down driveline sections parallel to each other and check for minimum 6 inches (152mm) overlap. (Figure 2-2) If driveline has been marked for cutting, overlap will be the distance between two marks. If driveline has less than minimum overlap, DO NOT USE. Contact authorized Bush Hog dealer. WARNING NEVER STAND BETWEEN TRACTOR AND CUTTER WHILE TRACTOR IS BEING BACKED TO HITCH. WARNING ADDITIONAL TRACTOR FRONT BALLAST MAY BE NEEDED FOR STABLE OPERATION AND TRANSPORT OF CUTTER. SEE TRACTOR OPERA- TOR’S MANUAL FOR RECOMMENDED WEIGHTS. IT IS RECOMMENDED THAT TRACTOR BE EQUIPPED WITH ROLLOVER PROTECTIVE SYSTEM (ROPS) AND SEAT BELTS. NOTE Due to the many variations in tractor/implement hitch points and corre- sponding differences in distances between tractor PTO shafts and implement input shafts, drivelines may need to be short- ened as described in the following steps: NOTE If driveline is correct length, omit the following steps “G” through “J” and proceed to step “K”.
