Traveling at the slowest forward speed with rear shield fully lowered will give finest possible finish. This shield adjustment is good for mulching, mixing, and burying weeds, fertilizer, etc. The more you increase forward speed and shield height, the coars- er the finished results will be. To leave the ground surface rough with larger clods and residue exposed, work with shield fully raised. When working in rocky soil, always have shield in raised position. Figure 3-1 Adjustments Adjustable, Spring-Loaded Shock Absorber 3-3 OPERATION A. Perform BEFORE EACH USE maintenance listed in paragraph 4-1. B. Adjust for work per paragraph 3-2. C. Start tractor. Raise tiller off the ground. D. With tractor at idle speed, engage PTO drive. DANGER STAY CLEAR OF ROTATING DRIVELINES. DO NOT OPERATE WITHOUT DRIVELINE SHIELDS IN PLACE AND IN GOOD CONDI- TION. FAILURE TO HEED THESE WARN- INGS MAY RESULT IN PERSONAL INJURY OR DEATH. DANGER KEEP HANDS AND FEET FROM UNDER MACHINE AT ALL TIMES. MAKE CERTAIN EVERYONE IS CLEAR OF MACHINE BEFORE OPERATING. FAILURE TO HEED THESE WARNINGS MAY RESULT IN PER- SONAL INJURY OR DEATH. E. Place tractor in gear and proceed forward. Increase speed to 3/4 throttle. Lower tiller into soil. Increase speed to 540 PTO rpm. Average soil with reasonable moisture will allow travel speeds up to 2 mph. Hard soil will require low travel speed, less than 1 mph to ensure smooth operation and maxi- mum possible depth. Shallow weed cultivation will allow speeds up to 3 mph. At the end of a pass lift tiller clear of ground before making a turn. After turn- ing, proceed back across field, slowly lowering the tiller into the soil. Do not turn with tiller in the ground as this can damage tiller and tractor link- age. Never use reverse gear while tiller is low- ered into ground. Avoid operating tiller in the raised position. 3-4 TRANSPORTING Do not engage PTO drive while transporting tiller. Obey all state and local laws when transporting on public roads. Always use flashing warning lights unless prohibited by law.
