CHECK CHAIN ADJUSTMENT
1.Refer to Install Optional Check Chains, page 42 for check chain installation.
2.After making cutting height adjustment, adjust both chains (3) in check chain bracket (2) so you have the same number of links on each side. This will keep cutting level.

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 2 to 5 mph. Tall, dense material should be cut at a low speed; thin,
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
Keep children and bystanders away from stor- age area.
