Figure 1A. Attitude Rod Adjustment
Cutting Height (Normal Mowing) - Wings
1. Lower wings to normal mowing position.
2. Loosen the jam nut on the adjustable link (turn
buckle).
3. Lengthening the link will raise the wing, shortening
the link will lower the wing. The rear edge of the
wing should be parallel to the ground.
4. Make sure jam nuts are tightened once wing is
leveled.
When using the cutter to shred, the rear of the cutter
deck should be approximately 1/2" to 1" lower than the
front.
NOTE: Equal Angle Drive Only: With the cutting height
established, adjust the driveline carrier bearing in the
H-frame to ensure the front driveline is parallel to the
ground with cutter in cutting position.
TRACTOR OPERATION
 Power unit must be equipped with ROPS or
ROPS cab and seat belt. Keep seat belt securely
fastened. Falling off power unit can result in death
from being run over or crushed. Keep foldable
ROPS system in “locked up” position at all times.
Use care when operating around tree limbs and other
low objects. Avoid being knocked off tractor and being
injured.
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 recommended
PTO operating RPM.
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.
CUTTER OPERATION
When beginning operation of the cutter, make sure that
all persons are in a safe location.
Power for operating the cutter is supplied by the tractor
PTO. Operate PTO at 540 (1000 RPM for "Q" models).
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 or 1000
RPM depending on model 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,
medium-height material can be cut at a faster ground
speed.
Always operate tractor PTO at proper RPM (540 or
1000 depending on model) 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 or 1000 RPM.
The lower ground speed will permit grass to rebound
partially.
Mowing Tips
 Look down and to the rear and make sure area
is clear before operating in reverse.
 Do not operate or transport on steep slopes.
 Do not stop, start, or change directions sud-
denly on slopes.
