AUTO - DRIVE OPERATION
Forward and reverse movement of the mower is controlled by the drive selector pedal. Ground speed of the ride-on
mower is controlled by the amount of pressure on the drive selector pedal. Ensure that the mower user is familiar
with this means of operation before operating the mower, particularly in tight confined areas.

The engine will not start unless the cutter
drive is disengaged, and clutch/brake
pedal is depressed and parking brake
applied.

2. Centralise engagement lever with the friction plates
between the drive pulleys.
3. Re-tighten locknut (A). Fig. 22
