4.2.4. 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 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.
7. Turn eccentric "UP" or "DOWN" as required until
blade tips are within 1/8" of each other. See Figure 4.4.
8. Tighten shoulder bolt loosened in step "6".
9. Readjust rear hanger chain pivots to align with
holes in support brackets. See Figure 4.5.
10. Remove angle iron, pipe, or similar object and
proceed to check front to rear levelness.
