ATTITUDE ADJUSTMENT (PULL-TYPE)
Normal Mowing
For the most economical power use and best cutting results, the cutter should be from 1/2" to 3/4" higher at the rear than at the front.
For grass and weed mowing, adjust cutter to run level or with the front slightly lower.
Shredding
For shredding, it is better to set rear of cutter slightly lower than the front. How much lower depends on the material to be shredded. Determine the best setting for your situation by experimenting. Use a slow ground speed for better shredding.
DRIVELINE ADJUSTMENT (PULL-TYPE)
With the cutting height established, adjust the driveline carrier bearings in the
WHEEL SPACING
Wheels may be adjusted to any position for row crop shredding.
BLADE SELECTION
Optional stump jumpers are recommended for rugged terrain where hidden rocks, stumps, and other objects may be encountered.
There are two blade options available for this cutter: standard suction blades and

NOTE: Blades must be moved in pairs. Never use one new blade and one used blade on a crossbar. Crossbar can become unbalanced.
TRACTOR OPERATION
Use care when operating around tree limbs and other low objects.
Use care and reduce ground speed on rough terrain. Always watch for hidden hazards.
Being knocked off or falling off tractor can result in seri- ous injury or death.
Only use a tractor with a Roll Over Protective Structure (ROPS) and seat belt. Securely fasten seat belt before starting tractor.
The cutter is operated with tractor controls. Engage the PTO at a low rpm to prevent excessive loads on the cutter drive system. Increase throttle to proper PTO speed 540 rpm (1000 rpm on "Q" models).
Be sure operator is familiar with all controls and can stop tractor and cutter quickly in an emergency. The operator should give complete, undivided attention to operating tractor and cutter.
OPERATING TECHNIQUE
Power for operating the cutter is supplied by the tractor PTO. Operate PTO at 540 rpm (1000 rpm on "Q" mod- els). Know how to stop the tractor and cutter quickly in an emergency.
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 (1000 rpm on "Q" models) and maintain throughout cutting operation.
Gearbox protection is provided by a slip clutch with replacement fiber disc. The slip clutch is designed to slip when excessive torsional loads occur.
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,
Always operate tractor PTO at proper rpm (540 or 1000) to maintain blade speed and to produce a clean cut.
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 (1000 rpm on "Q" models). The lower ground speed will permit grass to rebound partially.
