!
CAUTION!
To prevent personal injury caused by thrownobjects, the use of
front & rear safety guards is strongly recommended! To avoid
injury or death from entanglement in rotating drivelines, the
drive gearbox shields must be in place and secure when operating.
!
DANGER!
Rotary cutters have the ability to discharge objects at high
speeds; therefore, the use of front & rear safety shields is
strongly recommended when cutting along highways or in an
area where people may be present.
Cutting Instructions
1. Your cutter is equipped with free swinging cutting
blades to reduce shock loads to the cutter if striking
obstacles.
2. Start the machineslowly; do notusefull throttle.Allow
10 seconds for cutter blades to become aligned properly before going to full power.
3. Thegroundspeed depends on twothings; the density
of the material to be cut, and the size of the tractor.
Neverrun fast enough to overload the tractor.
4. Itis important tomaintain540 RPMPTOor1000 RPM
speed. Loss of PTO speed will allow the blades to
hinge back and result in ragged, uneven cutting.

Adjustments
Lift-Type Cutting Height
Refer to Figure 3-1:
!
CAUTION!
Engage parking brake, shut off tractor, remove key and disengage PTO before making any height adjustments!
1. Lower cutter onto safely supported blocks to desired
cutting height. Be certaincutter is level.
2. If cutter is equipped with optional hydraulic height adjustment, connect cylinder hoses to tractor remote
outlets.
3. Adjust the cutting height using ratchet jack or hydraulically if equipped with hydraulic cylinder.
Lift-Type Cutting Height Adjustment
Figure 3-1
14263
4. Adjust the tractor’slower 3-point hitch arms to level
cutter left to right. Set tractor 3-point depth stop when
cutter is level to maintain a consistent mowing weight.
Pull-Type Cutting Height
1. The cutting height can be adjusted by extendingor retracting the hydraulic cylinder to the desired cutting
height.
2. Once the cutter has been leveled, it will remain level
regardless of change in cutting height unless tractor
drawbar height or tailwheel size is changed.
3. Should the cutter require additional leveling adjustment:
a. Turn nut on leveling tube counterclockwise to low-
erfront of cutterandclockwise toraise front ofcutter.
b. Secure with jam nut.
Deck Attitude Adjustment
Figure 3-2
Deck Attitude Adjustment
Refer to Figure 3-2:
This adjustment is very important. With the deck positioned at this attitude, the blades will be cutting material
onlyatthe front of thecutter. If the deckis level,or the rear
of the cutter is lower than the front, the blades are subject
to continuous material flow which results in additional
bladewearand horsepower loss as well as morefrequent
blade sharpening.
