ROPS spring pin housing.

Hydro pump control arm, linkage bolt, and attachment bolt.

Hydro cooling fan screw.

Hydro park brake cable anchor mounting bolt

Copper-Based Anti-seize

Copper-based anti-seize is used in the following location:

On threads of Blade Bolts. See Check Mower Blades section.

Dielectric Grease

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 25).
