WARNING
Do not raise wings up with PTO engaged and drivelines
rotating. Objects can be thrown by the rotating blades and
driveline yokes can break as the wings are raised. Always keep
people away from a cutter that is operating.
!
WARNING
Do not operate cutter with loose pins, bolts and nuts. Loose
hardware can result in a serious breakdown causing bodily
injury or death.
!
WARNING
Do not operate cutter with a hitch or hitch pin that is
excessively worn, has structural cracks, is bent, or broken. The
hitch and/or hitch pin can break apart separating cutter from
tractor causing serious injury or death.
!
CAUTION
Do not exceed the rated cutting capacity! See Specifications &
Capacities for specified cutting capacity. Using this cutter for
any other type of work can damage drive components, cutter
blades and deck components!
!
CAUTION
Do not over speed PTO or machine damage may result. Many
tractors provide both 540 and 1,000 RPM PTO speeds. Check
your tractor’s manual to determine its capabilities.
• RC series cutters are designed for 540 RPM rear PTO.
• RCM series cutters are designed for 1000 RPM rear PTO.
IMPORTANT: Maintain correct PTO speed. Loss of
PTO speed will allow blades to swing back and
result in ragged, uneven cutting. Excessive speed
will cause damage to the power train components.
IMPORTANT: Avoid catching hydraulic hoses on
brush, post, stumps, and other protrusions that
could damage and/or break them.
IMPORTANT: If wing driveline profile is bent or
twisted, disconnect that driveline from the wing
gearbox before folding the wing up. This will protect
both the wing and divider gearbox. Repair driveline
before putting cutter back into service.
IMPORTANT: Your Rotary Cutter is equipped with
free swinging cutting blades to reduce shock loads
when striking obstacles. However, it is best to avoid
striking obstacles to extend cutter and blade life.
IMPORTANT: Watch while making tight turns to
ensure that the rear tractor tires and lower 3-point
arms do not make contact with cutter hitch, driveline
or deck. Keep lower 3-point arms raised at all times
when hitched to a pull type cutter.
Avoid Extreme Turning Angles
Refer to Figure 3-1 & Figure 3-2:
Plan your field cutting to minimize number of turns,
especially extreme turning angles. Avoid tractor-to-cutter
turning angles that exceeds the driveline’s maximum
turning angle. If the turn cannot be avoided, disengage
tractor PTO and wait for the driveline to stop rotating
before making the turn.

Standard Conventional Driveline:
Maximum turning angle = 35

•
Constant Velocity Driveline:
Maximum turning angle = 80
