Section 4 - ADJUSTMENT & REPAIR
4.2.5. MOWER DECK ADJUSTMENT (LEVELNESS)
SIDE-To-SIDE (48" 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 machine on a smooth level surface.
2. Rotate outside blades so tips are pointed to the
sides of deck. See Figure 4.5. 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 118", continue to
next step for adjustment.
3. Place a 2 x 4 piece of wood under the front
middle portion of deck. Place one 2 x 4 piece of
wood under the rear of deck on both sides behind
the two outside blades. See Figure 4.5.
4. Lower deck down to rest on the three 2 x 4 pieces
of wood. Make sure there is no deck tension on
the lift rods supporting the deck.
5. Loosen the bolt and nut that secures the front lift arm
weldment to the front lift arm. See Figure 4.6.
