3-3 OPERATION

A. Perform BEFORE EACH USE maintenance
listed in paragraph 4-1.
B. Start tractor per tractor operator's manual.
C. Raise/lower 3-point hitch to place cutter in
working position,
D. Look to be sure no one is near cutter. WITH
TRACTOR AT IDLE SPEED, SLOWLY ENGAGE PTO
DRIVE. This will prolong life of driveline components.

ROTATING CUTTER BLADES. STAND
CLEAR UNTIL ALL MOTION HAS STOPPED.
TO AVOID AN ACCIDENTAL FALL FROM
TRACTOR AND POSSIBLE INJURY BY
MOWER, IT IS RECOMMENDED THAT
TRACTOR BE EQUIPPED WITH ROLLOVER
PROTECTIVE SYSTEM (ROPS) AND A SEAT
BELT BE USED BY THE OPERATOR FOR
ALL MOWING OPERATIONS.
E. Place tractor in gear and proceed forward.
Advance the throttle to 540 PTO RPM. Tractor for-
ward speed should be controlled by gear selection,
not engine speed. For maximum cutting efficiency,
forward speed should allow cutter to maintain a con-
stant 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 cutter continuously stalls, select
lower tractor gear and/or increase cutting height.
Blade rotation is counterclockwise causing cut mate-
rial to discharge to the left side of cutter forming a
windrow. To shred and dissipate this window, tractor
should be driven in a counterclockwise direction
throwing material to the uncut area. The windrowed
material will be recut on each new pass. Tractor tire
tracks are cut more efficiently when tractor is travel-
ing in a clockwise direction especially when cutting
height is high. Counterclockwise tractor travel
requires more horsepower. Larger brush should be
cut in the center of cutter. Always cut up and down
the face of slopes, never across.
ALL ROTARY CUTTERS CAN DISCHARGE
OBJECTS AT HIGH SPEEDS WHICH
COULD RESULT IN SERIOUS INJURY TO
BYSTANDERS OR PASSERS-BY.
THEREFORE, THIS CUTTER IS NOT TO BE
OPERATED ALONG HIGHWAYS OR IN ANY
AREA WHERE PEOPLE MAY BE PRESENT
UNLESS ALL SIDES OF THE UNIT ARE
ENCLOSED BY PERMANENT BANDS THAT
ARE IN GOOD REPAIR.
