Breakaway pressure is regulated by the tension of the latch springs (Figure 3-3). Spring length as shipped from the factory is 4-1/8” and is satisfactory for most conditions. Breakaway pressure can be increased by turning spring retaining nuts clockwise or decreased by turning counterclockwise. DO NOT COLLAPSE SPRING TO LESS THAN 3-3/4” OR SPRING WILL BECOME SOLID BEFORE LATCH CAN TRIP.

3-5 OPERATION

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

B. Pin parking stand and transport latch in the work position.

C.Start tractor. Set tractor 3-point hitch depth control or install the optional check chain assembly to stop with the horizontal main frame pivot approxi- mately 20” from the ground. (Figure 2-4) Check chain retainers should be installed onto tractor rear casting using top link pin.

D.Lower cutter bar parallel to ground. Lower 3- point hitch to work position. Place control valve for cutter bar cylinder in “float” position.

DANGER

TO AVOID SERIOUS INJURY OR DEATH: STAY CLEAR OF ROTATING DRIVELINE.

DO NOT OPERATE WITHOUT DRIVELINE SHIELDS IN PLACE AND IN GOOD CONDITION.

DANGER

TO AVOID SERIOUS INJURY OR DEATH: STAND CLEAR OF ROTATING MOWER BLADES UNTIL ALL MOTION HAS STOPPED. TO AVOID ACCIDENTAL FALL FROM TRACTOR AND POSSIBLE INJURY FROM MOWER, IT IS RECOM- MENDED THAT TRACTOR BE EQUIPPED WITH ROLLOVER PROTECTIVE SYSTEM (ROPS) AND THAT A SEAT BELT BE USED FOR ALL MOWING OPERATIONS.

E. With tractor at idle speed, engage PTO drive. Set tractor throttle for 540 PTO rpm for models GHM 700, GHM 800, and GHM 900 and 1000 PTO rpm for models GHM 1800 and GHM 1900.

F. Place tractor in a gear that will give proper speed for terrain and crop conditions , then begin mowing. Tractor forward speed should be controlled by gear selection, not engine speed. For maximum efficiency, forward speed should allow mower to maintain a constant maximum blade speed.

If tractor engine stalls, do not slip tractor clutch to allow engine to regain speed as this will exert tremendous strain on the driveline. When stalling occurs,disengage PTO drive, move to a cut area,set tractor throttle at idle, then re-engage PTO drive. If stalling continues, use lower gear.

DANGER

TO AVOID SERIOUS INJURY OR DEATH FROM THROWN OBJECTS:

DO NOT OPERATE WITH CURTAIN GUARD REMOVED. DO NOT OPERATE WITHOUT CURTAIN GUARD IN GOOD CONDITION OR REPAIR.

3-6 SWATH BOARD

The swath board is manufactured in the correct posi- tion for most efficient operation. However, some conditions may require that the swath board be removed. To do this remove the bolt at the spring assembly and remove the complete assembly.
