Section 4 - ADJUSTMENTS & REPAIR
WARNING
DO NOT attempt any adjustments, maintenance or
service with the engine or blade running. STOP
blade. STOP engine. Set brake. Remove key.
Remove spark plug wire from spark plug and secure
wire away from spark plug. Engine and components
can be extremely hot. Avoid burns by allowing
engine and components sufficient time to cool.
4.2.9. MOWER DECK ADJUSTMENT (LEVELNESS)
1. Side-To-Side (42”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:
a.
Place SCRAMBLER on a smooth level
surface.
b.
Turn engine off and remove key, remove
spark plug wire(s) from spark plug(s) and secure
wire(s) away from plug(s).
c.
Place a piece of angle iron, pipe, or similar
object under center of deck at the rear.
d.
Remove rear hanger chains and allow center,
rear of deck to rest on angle iron.
e.
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 Step “
f
” for adjustment. See Figure 4.6.
f.
Loosen the shoulder bolt that retains the
eccentric.
g.
Turn eccentric “UP” or “DOWN” as required
until blade tips are within 1/8” of the same
distance from the floor. See Figure 4.7.
h.
Tighten shoulder bolt loosened in Step “f”.
i.
Readjust rear hanger chain pivots to align
with holes in support brackets.
j.
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.
k.
Proceed to check front to rear deck pitch.
