OPERATING TECHNIQUE
1.
Power for operating the cutter is supplied by the tractor PTO. Operate
PTO at 540 rpm. Know how to stop the tractor and cutter quickly in an
emergency.
2.
Engage PTO at a low engine rpm to minimize stress on the drive system
and gearbox. With PTO engaged, raise PTO speed to 540 rpm and
maintain throughout cutting operation.
Gearbox protection is provided by a slip clutch with replacement fiber
disc or a shear bolt. The slip clutch is designed to slip and the shear bolt
will shear when excessive torsion loads occur.
3.
Move slowly into material. Adjust tractor ground speed to provide a clean
cut without lugging the tractor engine. Use a slow ground speed for better
shredding.
Proper ground speed will depend on the terrain and the material's height,
type, and density.
Normally, ground speed will range from 3.22 to 8.05 kph (2 to 5 mph).
Tall, dense material should be cut at a low speed; thin, medium-height
material can be cut at a faster ground speed.
4.
Always operate tractor PTO at 540 rpm to maintain proper blade speed
and to produce a clean cut.
5.
Under certain conditions tractor tires may roll down some grass and
prevent cutting at the same height as the surrounding area. When this
occurs, reduce your ground speed but maintain PTO at 540 rpm. The
lower ground speed will permit grass to rebound partially.
STORAGE

Disconnect cutter driveshaft and secure up off ground. Raise cutter
with 3-point hitch. Place blocks under cutter side skids. Lower cutter
onto blocks. Disconnect cutter from tractor 3-point hitch and carefully
drive tractor away from cutter.

Keep children and bystanders away from storage area.
