Deck Leveling Adjustment
See Figure 8-2.
1. Park the mower safely. (See “Park Mower Safely” on
page 1-6.)
2. Set all tire pressures for machine and caster wheels.
Set front machine tires at 16–20 psi (110–138 kPa),
rear machine tires at 10–12 psi (69–83 kPa), and
caster tires at 20–25 psi (138–172 kPa).

3. With all decks lifted slightly off the ground, loosen all
the caster wheel arms where bolted to the deck shell
brackets (1). Position the arms so the top of the arm
is parallel with the top of the mounting bracket on the
deck. The caster arms should be level and parallel to
the deck shell as shown. This will bring the decks
close to the actual height-of-cut range. Tighten all
caster wheel arms in this leveled position.

NOTE
Each swiveling caster wheel is assembled with at least
two 1/8 inch flat washers (1) along with the 1/2 inch
height-of-cut spacers (2) used to set the cutting height.
1. Make sure that 1/8 inch flat washers (1) are installed
above the caster wheel arms.
2. Install only the proper number of 1/2 inch spacers (2)
for desired height-of-cut setting.
3. With front deck down on the ground and front casters
swiveled in the forward travel position, place a level
on the center of the front deck.
