Section 4 - ADJUSTMENTS & REPAIR
WARNING
DO NOT attempt any adjustments, maintenance,
service or repairs with the engine running. Stop
engine. Stop blade. Engage parking brake. Remove
key. Remove spark plug wire from spark plug and
secure away from plug. Engine and components are
HOT. Avoid serious burns; allow all parts to cool
before working on machine. Fuel Filler Cap and Vent
must be closed securely to prevent fuel spillage.
4.3.7. MOWER DECK ADJUSTMENT (LEVELNESS)
Side-To-Side (33” Decks)
Before making deck leveling adjustments, check
the tire pressure. Check tires and add or release air
as needed to bring pressure to 12 P.S.I. in front and 12
P.S.I. 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 4.8.
FIGURE 4.8
6. Loosen the shoulder bolt that retains the
eccentric.
7. Turn eccentric “UP” or “DOWN” as required
until blade tips are within 1/8” of the same
distance from the floor. See Figure 4.9.
8. Tighten shoulder bolt loosened in Step “f”.
9. Readjust rear hanger chain pivots to align
with holes in support brackets.
10. Reconnect hanger chains, remove angle
iron, pipe, etc. and recheck side to side level.
Adjust either chain as needed to result in blade
tips being within 1/8” of the same distance from
the floor.
11. Proceed to check front to rear deck pitch.
FIGURE 4.9
4.3.8. MOWER DECK ADJUSTMENT (LEVELNESS)
Front to Rear Deck Pitch (33” Deck)
With the YARD CRUISER on a smooth, level
surface, rotate blade until blade tips are at front and
rear of deck. Measure the distance from blade tips
to floor. The distance should be the same, or the
rear 1/4” lower than the front. If the rear blade tip is
higher or is more than 1/4” lower than the front,
proceed with adjustment.
1. Remove rear hanger chains.
2. Turn each hanger pivot the same number of
rotations on the eye-bolt to raise or lower the
rear of the deck. See Figure 4.10.
3. Reinstall rear hanger chains and measure
blade tips again.
4. Repeat steps “a” through “c” until proper
levelness is obtained.
