Maintenance

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 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.

Deck Leveling

1.Position the mower on a flat surface.

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

3.Check the tire pressure in the drive tires. Proper inflation pressure for tires is 13 psi (90 kPa). Adjust if necessary.

4.Position the transport lock in the latching position.

5.Push the foot pedal all the way forward and the deck will latch at the 5 1/2 inch (14 cm) transport position (Figure 26).

6.Insert the height adjustment pin into the 3 inch (7.6 cm) cutting height location.

7.Release the transport lock and allow the deck to lower to the cutting height.

8.Raise the discharge deflector.

9.Measure from the level surface to the front tip of the center blade. The measurement should read 3 inches (7.6 mm).

Note: In most conditions, the back blade tip should be adjusted 1/4 inch (6.4 mm) higher than the front.
