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. Remove the hairpin and clevis pin (see Figure 26).
