Adjustments

Note: Disengage PTO, shut off engine, wait for all moving parts to stop, engage parking brake, and remove key before servicing, cleaning, or making any adjustments to the unit.

CAUTION

Raising the mower 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.

Deck Leveling

1.Park the machine on a level surface and disengage the blade control switch.

2.Stop engine, wait for all moving parts to stop, and remove key. Engage parking brake.

3.Check the air pressure in the drive tires. If needed, adjust to the recommended inflation; refer to Checking the Tire Pressure in Drive System Maintenance section.

4.Set the height of cut lever to the 3 inch (7.6 cm) position.

5.Raise the discharge deflector.

6.Carefully rotate the blades front to rear. Measure from the tip of the front blade to the level surface (Figure 22). The blades should measure 3 inches (7.6 cm).
