Driveline Turning Angle
Refer to Figure 3-4 & Figure 3-5:
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
o
.
• Constant velocity driveline:
Maximum turning angle = 80

General Operating Instructions
!
DANGER!
Do not operate 20 ft. cutters without both wings attached to the
center deck. Removing one wing will expose blades and
increase risk of cutter overturning. Removing both wings will
expose blades on both sides. Exposed blades can result in
serious injury and/or death.
!
DANGER!
Do not lift deck to use cutting blades as a fan. Cutting blades
are not properly designed or guarded for this use. Using the
deck as a fan can result in injury and/or death.
!
DANGER!
Damaged drivelines can brake apart while rotating at high
speeds causing serious injury or death. Always remove Rotary
Cutter from service until damaged drivelines are repaired or
replaced.

DANGER!
Do not engage tractor PTO while hooking-up and unhooking
the driveline or while someone is standing near a rotating
driveline. A person’s body and/or clothing can become
entangled in the driveline resulting in serious injury or death.
!
DANGER!
Rotary cutters have the ability to discharge objects at high
speeds. To prevent personal injury caused by thrown objects,
the use of front & rear safety guards is strongly recommended!
!
WARNING!
Tractor PTO shield, all Rotary Cutter gearbox shields and
driveline shields must be in place and secured while the cutter
is operating to avoid injury or death from entanglement in
rotating drivelines!
!
WARNING!
Refer to Figure 5-1 on page 24. Keep blade bolt access hole “A”
covered at all times except when servicing cutter blades (#3).
Make sure the main driveline is disconnected from the tractor
before removing access cover (#7).
!
CAUTION!
Do not exceed the rated cutting capacity of the cutter! See
Specifications and Capacities on page 35 for cutting capacity of
your specific unit. Using this cutter for any other type of work
can damage the drive components, cutter blades and deck
components!
!
CAUTION!
Always disengage PTO, engage parking brake, shut tractor
engine off, remove switch key and wait for blades to come a
complete stop before dismounting from tractor.
!
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 a tractor with 540 RPM
rear PTO.
• RCM series cutters are designed for a tractor with 1000
RPM rear PTO.
IMPORTANT: Avoid catching hydraulic hoses on
brush, post, stumps, and other protrusions that
could damage and/or break them.
NOTE: 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 life and life of
cutting blades.
