each side of the cutting deck. Place two “A” thick blocks (see Block Height and Rake Table in Deck Leveling) under each side of the front edge of the deck, but not under the anti-scalp roller brackets.

7.Loosen the leveling adjust locking nuts (item 1 Figure 26) on all four corners so that the deck is sitting securely on all four blocks. Make sure that the slack is removed from the deck hangers and the deck lift foot lever is pushed back against the stop, then tighten the four leveling adjust locking nuts.

8.Carefully rotate the blades so they are facing front to rear (Figure 27).

9.Measure from the tip of the front blade to the flat surface and the tip of the rear blade to the flat surface (Figure 27). If the front blade tip is not “R” (see Block Height and Rake Table in Deck Leveling) lower than the rear blade tip, adjust the front deck hanger.

Adjusting the Parking Brake

Service Interval: Every 500 hours

Check to make sure brake is adjusted properly. This procedure must be followed after the first 100 hours or when a brake component has been removed or replaced.

1.Drive the machine onto a level surface.

2.Disengage the blade control switch (PTO), move the motion control levers to the neutral locked position and set the parking brake.

3.Stop the engine, wait for all moving parts to stop, and remove the key.

4.Setup the machine to be pushed by hand (see Drive Wheel Release Valves in the Operation section).

5.Raise the back of the machine up and support the machine with jack stands.

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.

6.Engage/disengage the brake and check each drive tire to make sure each brake engages/disengages.

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 28).
