4.2.3.MOWER DECK ADJUSTMENT (Side-To-Side Levelness)

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.

1.Place Rider on a smooth level surface.

2.Follow WARNING statement found on this page.

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 carriage bolt and nut retaining the left side of the front lift arm and adjuster. Only loosen the bolt and nut to the point where some tension remains but lift arm can be moved.
