OPERATION
• Follow Safe Operating Procedures
• Keep Riders Off Machine
Keep riders off. Riders are subject
to injury or death such as being struck by foreign
objects and being thrown off the machine. Riders
may also fall off and be run over by machine.
Riders also obstruct the operator’s view resulting
in the machine being operated in an unsafe manner.
• Follow Safety Operating Procedures
To help prevent severe injury or
death to you or someone else:
Never operate cutter when other people are in
the vicinity. Debris can be thrown hundreds of
feet. Keep all guards in place. Including those
on discharge opening at front and rear of deck.
Before starting machine, lower to the ground.
Engage tractor PTO and gradually increase
the speed.
Operate tractor at rated PTO speed. If engine
speed is too slow or too fast, machine may not
perform properly.
Where conditions make it necessary to slow
ground speed, shift to a lower gear rather than
reducing engine speed. The engine will maintain
rated speed and keep cutter running at
optimum cutting speed.
Operate machine from tractor seat only.
Never adjust machine while in motion.
Slow down when turning or traveling over
rough ground.
Avoid holes when operating on hillsides. Tractor
roll-over could result.
Shut off tractor engine and engage tractor
parking brake and/or place transmission in
“Park” when leaving tractor. Remove key
when leaving tractor unattended.
Components behind shields may rotate several
minutes after power is shut off. Look and listen
for evidence of rotation before removing shielding.

the driveline to contact the cutter frame or tractor
tires to contact the foot guards or chain shield. Raise
the cutter slowly and check for interference. Lengthen
tractor lift links to provide clearance to full height.
NOTE: Lift height may also be limited by installing
stops on rockshaft control lever bracket.
8. Lengthen tractor lift links, if necessary, to
provide clearance.
9. Adjust tractor center link
until bushing is centered
in slot.
maintain a constant, maximum blade
speed. If cutter stalls or tractor engine bogs,
disengage PTO. Before re-engaging PTO, position
cutter in a cut area and reduce tractor throttle to
idle. If rotary cutter continuously stalls, select lower
gear and/or increase cutting height.
Note:
Tractor forward speed should be controlled by gear
selection, not engine speed. For maximum cutting
effi ciency, forward speed should allow cutter to
