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.Carefully rotate the blades from side to side.

6.Measure between the outside cutting edges and the flat surface (Figure 23 and Figure 24). If both measurements are not within 3/16 inch (5 mm), an adjustment is required; continue with this procedure.
