Resumen del manual
If driveline has less than minimum overlap, DO NOT USE. Contact authorized Bush Hog dealer. NOTE If driveline is correct length, omit the fol- lowing steps “G” through “J” and proceed to step “K”. Figure 2-1Figure 2-2MinimumOverlap 7 G. Clamp end of driveline in a vice. Cut off shield where marked. (Figure 2-3). Figure 2-3 H. Usingcut off section of shield as a guide, cutshaft the same amount. (Figure 2-4) Figure 2-4 I. Repeat steps “G” and “H” to other driveline sec- tion. J. Deburr ends of driveline sections and clean away all chips and filings. (Figure 2-5) K. Apply multi-purpose grease to outside of male driveline section. Assemble driveline and install on tractor and cutter. Pull on each driveline section to be sure yokes lock into place. Make certain driveline shielding is in place and in good condition. Figure 2-5 DANGER MAKE CERTAIN DRIVELINE YOKES ARE SECURELY FASTENED. FAILURE TO DO SO MAY RESULT IN SERIOUS INJURY. L. Raise cutter off ground and adjust lower lift arms to level cutter right to left. Refer to tractor oper- ator’s manual. M. Lower cutter to work position. Adjust tractor top link to position cutter top flex link as shown in Figure 2-6. This allows cutter to “float” during opera- tion. Also lower the tractor lift arms so that lower links can also “float”. N. Adjust tractor sway chains, stabilizer bar or equivalent to prevent side sway.

Operator should wear hard hat, safety glasses and safety shoes. The operator should read, understand and practice all safety mes- sages shown on the caution, warning and danger decals affixed to the cutter to avoid serious injury or death. It is recommended that tractor be equipped with Rollover Protective System (ROPS) and a seat belt be used. Before beginning operation, clear work area of any objects that may be picked up and thrown. Check for ditches, stumps, holes or other obstacles that could upset tractor or damage cutter. Always lower cutter to ground and allow blades to come to a complete stop, set parking brake and turn off tractor engine before leaving tractor operator’s seat. 3-2 CUTTING HEIGHT ADJUSTMENT The cutter should be operated at the highest position that will give desired cutting results. This will help prevent blades from striking the ground, reducing blade wear and undue strain on the machine. Adjust as follows: A. Raise cutter off ground using tractor 3-point lift. SECURELY BLOCK CUTTER IN POSITION. WARNING THE CUTTER CAN FALL FROM HYDRAULIC SYSTEM FAILURE. TO AVOID SERIOUS INJURY OR DEATH, SECURELY SUPPORT CUTTER BEFORE WORKING UNDERNEATH. B.Remove pin securing caster stem to caster arm. (Figure 3-1). Remove caster stem from caster arm. C. Place amount of spacers on caster stem to give desired cutting height. With no spacers on the bottom, a 1” or slightly lower cutting height is given. D. Reinstall caster stem into caster arm. Place remaining spacers on caster stem above caster arm and install pin to retain. E. Repeat operation for all caster wheels. Make certain all wheels are adjusted to the same height. 3-3 OPERATION A. Perform BEFORE EACH USE maintenance list in paragraph 4-1. B. Start tractor. Lower cutter until it is supported by caster wheels. Position tractor lower lift arms so cutter lower links are parallel to ground. DANGER STAY CLEAR OF ROTATING DRIVELINE. DO NOT OPERATE WITHOUT DRIVELINE SHIELDS IN PLACE AND IN GOOD CONDITION. FAILURE TO HEED THESE WARNINGS MAY RESULT IN PERSONAL INJURY OR DEATH. Figure 3-1 SpacersCasterWheel DANGER STAND CLEAR OF ROTATING CUTTER BLADES UNTIL ALL MOTION HAS STOPPED. TO AVOID ACCIDENTAL FALL AND POSSIBLE INJURY FROM CUTTER, IT IS RECOMMENDED THAT TRACTOR BE EQUIPPED WITH ROLLOVER PRO- TECTIVE SYSTEM AND THAT A SEAT BELT BE USED FOR ALL OPERATIONS. C. With tractor at idle speed, engage PTO drive. Advance throttle to 540 PTO rpm. D. Place tractor in low gear and begin cutting. Tractor forward speed should be controlled by gear selection, not engine speed. For maximum cutting efficiency, forward speed should allow cutter to maintain a constant maximum blade speed. If tractor engine or cutter stalls, do not slip tractor clutch to allow engine to retain speed as this will exert undue strain on the implement drivetrain. When stalling occurs, disengage PTO drive, move to a cut area, set tractor throttle to idle, then re-engage PTO drive. Always cut up and down the face of slopes, never across. Check belt tension after first 8 hours. Adjust per- paragraph 4-3 if needed. 3-4 TRANSPORTING Turn off PTO drive and fully raise tractor 3-point lift before transporting. When implement is transported on road or highway, day or night, use tractor flashing warning lights unless prohibited by law. A slow mov- ing vehicle (SMV) sign must be visible from the rear by...
