Maintenance
CAUTION
Raising the mower deck for service or
maintenance relying solely on mechanical
or hydraulic jacks could be dangerous. The
mechanical or hydraulic jacks may not be
enough support or may malfunction allowing
the unit to fall, which could cause injury.
Do Not rely solely on mechanical or hydraulic
jacks for support. Use adequate jack stands
or equivalent support.
6. Engage/disengage the brake and check each drive
tire to make sure each brake engages/disengages.
7. If adjustment is necessary, loosen the jam nut
from the yoke on the side that needs adjustment.
