2. Check for straight-ahead operation and at full
turning angles. If there is any interference, remove
the lower lift links.
3. Contact between tractor lift links and cutter parts
can cause damage, especially when turning.
CV Driveline Turning Limits
NOTICE
■
You must not exceed a turning angle of 80
degrees at the head of the Constant Velocity drive-
line or damage will occur.
1. To check for potential excessive turn angle,
disconnect the driveline from tractor.
2. Start engine and turn as far right or left as possible.
3. Shut engine off and try to connect CV driveline to
tractor. If it cannot be connected, the turn angle is
too severe.
4. Restart engine and straighten angle slightly, shut
off engine and try to connect CV driveline to tractor.
5. Repeat the process until the driveline can be
connected. The point at which the driveline can be
connected is the maximum turn that should be
made.
Cutting Height Adjustment
NOTICE
■
Avoid ground contact with blades. Striking
ground with blades produces one of the most dam-
aging shock loads a cutter can encounter. If this
occurs repeatedly, the cutter, driveline, and gear-
boxes will be damaged.
Cutting height range is from 51 to 305 mm (2" to 12").
When selecting a cutting height, you should consider
the area of operation. If the ground is rolling and has
mounds the blades could contact, set the cutting height
accordingly. The cutting height (blade edge) is approxi-
mately 25.4 mm (1") above the bottom of the side skid.
Cutting Height (Normal Mowing) - Center Section
NOTE: Cutter is set at factory for tires that it
shipped with and a 419.1 mm (16.5") tractor draw-
bar height. The adjustment is only needed for dif-
ferent drawbar height or to change shredding
amount, and should be verified upon delivery.
1. Position the cutter on a hard level surface and
select an approximate cutting height, Example
152.4 mm (6").
2. Raise wings and lock them in the UP position.
14 Operation
ARNING
3. Raise or lower the center section to obtain a
distance of 127 mm (5") from bottom edge of skid
shoe to the ground.
4. Loosen jam nuts on the attitude rod that runs from
the wheel yoke to the tongue.
5. Adjust rod in or out until the rear of the cutter is
approximately 12.7 mm (1/2") higher than the front.
6. Tighten jam nuts against sleeve.
Cutting Height (Normal Mowing) - Wings
NOTE: Cutter is adjusted at factory for wings to
remain parallel to center frame through full range of
cut.
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.
When using the cutter to shred, the rear of the cutter
deck should be approximately 12.7 to 25.4 mm (1/2" to
1") lower than the front.
TRACTOR OPERATION
Use care when operating around tree limbs and other
low objects. Avoid being knocked off tractor and being
injured.
Only use a tractor with a Roll Over Protection Structure
(ROPS) and seat belt. Securely fasten seat belt.
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.
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 and main-
tain throughout cutting operation.
