Maintenance

“R” (see Block Height and Rake Table in Deck

Leveling) lower than the rear blade tip, adjust the blade level using the following instructions:

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

3. Move the motion control levers outward to the neutral position, engage the parking brake, stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.

4. Check the air pressure of all four tires. If needed, adjust to the recommended inflation; refer to

Checking the Tire Pressure in Drive System

Maintenance section.

5. Check and adjust the side-to-side blade level if you have not checked the setting; refer to Deck

Leveling.

6. Set the height-of-cut lever to the 3 inch (76 mm) position. Place two “B” thick blocks (see Block

Height and Rake Table in Deck Leveling) under the rear edge of the cutting deck skirt; one on 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 27) 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 28).

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 28). 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.
