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.

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 29).

9. When adjustment is complete, remove the jack stands or equivalent support and lower the machine.
