Stop tractor, by releasing the traction pedal, then slowly lower the mower units (5, Fig. J) and (7, Fig. Deck speed is constant and ground speed is variable with the traction pedal. Do not try to regulate ground speed with engine throttle (section 4. 5). 5. 6--HILLSIDE OPERATION The I-Trim has been designed for good traction and stability under normal mowing conditions. However, caution must still be used during slope operation, especially when the grass is wet. In order to minimize the possibility of tipping, the least dangerous method of operating on hills and terraces is to travel horizontally to the hill. It is also advisable to avoid any unnecessary turns while operating on hills. Use extreme caution and travel at reduce speeds. 19 6--ADJUSTMENTS 5. 8--AFTER OPERATION 1. Remove loose grass clippings and caked grass to prevent clogging the vented areas, lubrication points, and corroding parts. Do not permit dirt or grass clippings to accumulate on the air intake screen, engine or radiator/oil cooler to prevent serious heat damage to the engine, or hydraulic pump. Read each instruction completely and, make sure you understand it before making any adjustments. Follow all the safety precautions. To avoid possible serious injury, before making any adjustments or performing maintenance, engage parking brake, place all tractor controls in neutral, lower decks to the ground, turn ignition switch "off" and remove key. 5. 9--CLEANING RADIATOR AND OIL COOLER 1. If grass clippings become trapped in radiator and oil cooler, use compressed air from fan side to blow them out. The screenbox can tilted back for cleaning by loosening quick-latches (Sec. If grass clippings become trapped between radiator and oil cooler, the oil cooler can be tilted back for cleaning (Fig M). Be careful not to damage the fins on the radiator and oil cooler during cleaning. 6. 1--TRACTION PEDAL ADJUSTMENTS The traction pedal (1, Fig. M) is equipped with a safety switch (2, Fig. The switch prevents the engine from starting when the pedal is positioned in reverse or forward. Prior to adjusting for creep, elevate the wheels off the ground and support the vehicle with jack stands. To adjust the creep of the drive wheels, loosen the fastener attaching the clevis to the control arm. If needed, adjust the switch so that the engine cannot be started unless the pedal is in the neutral position. 6. 2--PARKING BRAKE ADJUSTMENT FIGURE L The parking brake should be set so that it holds the tractor securely. The parking brake must be released before the traction pedal is engaged. Adjust the brake by loosening set screw in the brake knob and turning knob clockwise to tighten, or counterclockwise to loosen, then retighten set screw.
