Leveling the Mower Deck

The mower blades must be level from side to side. Check the side-to-side level any time you install the mower or when you see an uneven cut on your lawn.

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

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

3.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. If either one is out of range then follow adjustment procedure.

4.Carefully rotate the blades side to side.

5.Measure between the outside cutting edges and the flat surface (Figure 44). If both measurements are not within 3/16 inch (5 mm), an adjustment is required; continue with this procedure.

7.Set anti-scalp rollers to top holes or remove completely for this adjustment.

8.Set the height-of-cut lever to the 3 inch (76 mm) position. Place two 2 1/2 inch (6.35 cm) thick blocks under the rear edge of the cutting deck skirt; one on each side of the cutting deck. Place two 2 5/16 inch (5.89 cm) blocks under each side of the front edge of the deck, but not under the anti-scalp roller brackets.

9.Carefully rotate the blades side to side (Figure 44).

10.Loosen the leveling adjust locking nuts (item 4) on all four corners so that the deck is sitting securely on all four blocks. Make sure that the deck hangers are all the way down (at the top of the slot) and the deck lift foot lever is pushed back against the stop, then tighten the four leveling adjust locking nuts

11.Recheck that blocks fit just snugly under the deck skirt. Make sure all attachment bolts are tight

12.Continue leveling the deck by checking the front-to-rear blade slope; refer to Adjusting the

Front-to-Rear Blade Slope.

13.Recheck blades for levelness and repeat deck leveling procedure if necessary.
