4.3.7. MOWER DECK ADJUSTMENT (LEVELNESS)
Side-To-Side (33" & 38" Decks)
Before making deck leveling adjustments, check
the tire pressure. Check tires and add or release air
as needed to bring pressure to 12 psi in front and 12
psi in rear tires. If tires are properly inflated and
mowing is still uneven, adjust side-to-side deck
levelness as follows:
1. Place YARD CRUISER on a smooth level
surface.
2. Turn engine off and remove key, remove
spark plug wire(s) from spark plug(s) and secure
wire(s) away from plug(s).
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 levelness is satisfactory. If the difference
from side-to-side is greater than 1/8", continue to
the next page for adjustment. See Figure 4.9.

tips being within 1/8" of the same distance from
the floor.
