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. (See “TIPS” on next page) This will help prevent blades from striking the ground, reducing blade wear and undue strain on the machine. Cutting too much material may reduce mulching action and leave visible clippings on the lawn surface. The more frequently the lawn is mowed, the better the mulching effect will be. 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 wheel to bracket. (Figure 3-1) Remove caster wheel from arm. C. Place amount of spacers on caster wheel to give desired cutting height. With no spacers on the bottom, a 3/4” cutting height is given. D. Reinstall caster wheel into caster arm. Place remaining spacers on caster wheel 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, allowing cutter to “float” during operation. Adjust top link as FIGURE 3-1 Caster Wheel Spacers Caster Wheel 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. 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 PROTECTIVE SYSTEM AND THAT A SEAT BELT BE USED FOR ALL OPERATIONS. shown in Figure 2-6. 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 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 moving vehicle (SMV) sign on the tractor must be visible from the rear by approaching vehicles. 10 TIPS ON MOWING WITH A MULCHER The Bush Hog MP 5/6 is a finishing mower with counter rotating blade sets designed to do a superior job of mulching grass clippings. To get the maximum effectiveness from your MP the tips listed below should be followed: . Mow often - In general, mulching operations require more frequent mowing than would conventional mowing procedures. . Watch your speed - Normal conditions will allow a speed of up to approximately 5 mph,but thick, heavy, damp conditions will require reduced ground speed. . Mow at 540 RPM to keep tip speed at its maximum. . Mow with a clean mower - Avoid grassy build-up under the deck. . Mow with sharp blades - A sharp blade cuts cleaner. . Wet grass will decrease distribution effectiveness and increase horsepower requirements. Leaves, on the other hand, may be more effectively mulched when they are slightly damp. . Mow at higher cutting heights - Remove and mulch no more than 2” - 2-1/2” of grass length with each mowing. (Experts recommend not cutting off more than 1/3 of the grass blade length at any given time.) . Mow twice, at different height settings, (high, then low), if grass is extra tall. . Keep your lawn clean, healthy and fertilized. Figure 3-2 Sharp blades and a clean mower enhance mowing performance. Removable Baffles NOTE: The MP 5/6 mulching mowers are equipped with adjustable, removable baffles on the rear sides of the outer blades. These baffles are factory installed in the intermediate position for the most common grass conditions. If extra fine mulching in light cutting conditions is desired, the baffles m...
