SECTION 3 - Operating Instructions

3-1 GENERAL SAFETY

Only qualified people should operate this machine. Operator should wear hard hat, safety glasses, and
safety shoes. It is recommended that tractor be equipped with Rollover Protective Systems (ROPS) and
a seat belt be used. Before beginning operation, clear work area of objects that may be picked up and
thrown. Check for ditches, stumps, holes, or other obstacles that could upset tractor or damage rotary
mower. Always turn off tractor engine, set parking brake, and allow rotary mower blades to come to a
complete stop before dismounting tractor.

3-2 ADJUSTING FOR WORK

The rotary mower should be operated at the highest position which will give optimal cutting results.
This will help prevent the blades from striking the ground, reducing blade wear and undue strain on the
machine. For best results under heavier cutting conditions, always tilt the rotary mower approximately
2 inches (51mm) lower in the front. This tilt decreases horsepower requirements and increases potential
ground speed. When fine shredding is desired, adjust rotary mower deck level or slightly lower in the
rear. This will keep the foliage under rotary mower until thoroughly shredded. More power is required
for shredding.
