Before making deck leveling adjustments, check the tire pressure. Front tires 12 psi, rear tires 12 psi. If tires are properly inflated and mowing is still uneven, adjust side-to-side deck levelness as follows:

1.Place Rider on a smooth level surface.

2.Turn engine off and remove key, remove spark plug wire from spark plug and secure wire away from plug.

3.Place a piece of angle iron, pipe, or similar object under center of deck at the rear.

4.Remove rear hanger chains and allow center, rear of deck to rest on angle iron.

5.Measure the distance from blade tips to floor. If the measurement is within 1/8” from side-to-side, the deck attitude is satisfactory. If difference from side-to- side is greater than 1/8”, continue with adjustment.

6.Loosen the shoulder bolt retaining the left side of blade pedals. See Figure 4.4.

7.Turn eccentric “UP” or “DOWN” as required until blade tips are within 1/8” of each other. See Figure 4.4.
