3-3 OPERATION

A. Perform BEFORE EACH USE maintenance list in paragraph 4-1.

B. Standard Models With Single Acting Cylinders - Start tractor. Lower cutter decks until it is supported by caster wheels and place hydraulic valve in “float” position.

Models Equipped With Double Acting Hydraulic Cylinder Conversion Kit - Start tractor. Lower cutter decks until it is supported by caster wheels and hydraulic cylinders are fully extended to allow mechanical float to operate. (Figure 3-2)

DANGER

STAY CLEAR OF ROTATING DRIVELINE. DO NOT OPERATE WITHOUT DRIVELINE SHIELDS IN PLACE AND IN GOOD CONDITION. FAILURE TO HEED THESE WARNINGS MAY RESULT IN PERSONAL INJURY OR DEATH.

DANGER

STAND CLEAR OF ROTATING CUTTER BLADES UNTIL ALL MOTION HAS STOPPED. TO AVOID ACCIDENTAL FALL AND POSSIBLE INJURY FROM CUTTER, IT IS RECOMMENDED THAT TRACTOR BE EQUIPPED WITH ROLLOVER PRO- TECTIVE SYSTEM AND THAT A SEAT BELT BE USED FOR ALL OPERATIONS

C. With tractor at idle speed, engage PTO drive. Advance throttle to 540 PTO rpm.

D. Place tractor in low gear and begin cutting. Tractor forward speed should be controlled by gear selection, not engine speed. For maximum cutting efficiency, forward speed should allow mower to maintain a constant maximum blade speed.

If tractor engine or cutter stalls, do not slip tractor clutch to allow engine to retain speed as this will exert undue strain on the implement drivetrain. When stalling occurs, disengage PTO drive, move to a cut area, set tractor throttle to idle, then re-engage PTO drive.

When mowing across slopes, yawing or skewing may occur as the mower slips sideways which may cause streaking. In this case, mowing up and down slopes should be done to eliminate skewing.

3-4 TRANSPORTING

IMPORTANT- Before folding for transport, disen- gage the PTO and wait for blades to stop. Pull the latch chain to allow complete folding, then release the chain to lock decks in the raised position. These locks also serve the purpose of limiting the upward flex of the cutter decks dur- ing operation.

Install pins into the transport lock positions. (Figures 3-3, 3-4, & 3-5) When implement is transported on road or highway, day or night, use tractor flashing warning lights unless prohibited by law. The slow moving vehicle (SMV) sign must be visible from the rear by approaching vehicles.

NOTE: The mower deck transport locking pins provid- ed on the wing sections (Figure 3-4) MUST be removed BEFORE operation. Failure to remove these locking pins will result in front caster wheel damage, turf damage, and unacceptable mowing performance
