[. . . ] It is best to mow along the side of the hill, starting at the bottom and working upwards. This allows the machine to negotiate the slope without mowing in a downhill direction. It is essential for the correct tire pressure to be established for maximum traction and hillside holding. 5. 7--PUSHING OR TOWING INSTRUCTIONS The I-Trim should not be pushed or towed with the engine not running. If needed, the I-Trim can be pushed or towed at slow speeds for very short distances without starting the engine. Do not exceed 2 mph while pushing or towing. A screw-adjustable valve is located on the underside of the pump for towing. Note: Do not exceed 2 mph while pushing or towing. Loosen the lock nut and turn the screw CCW to release pressure. After towing, tighten the screw by turning CW and lock into place with the locknut. 5. 5--MOWING 1. Stop tractor, by releasing the traction pedal, then slowly lower the mower units (5, Fig. J) and (7, Fig. J). Dropping mower decks abruptly could damage them. Always check for bystanders before lowering. 2. Depress traction pedal to the desired speed (sections 4. 6 and 4. 7). 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. Wet grass limits traction and steering control. 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.
