WHEEL ALIGNMENT
The caster (forward slant of the king pin) and the
camber (tilt of the wheels out at the top) require no ad¬
justment. Automotive steering principles have been
used to determine the caster and camber on the
mower. The front wheels should toe-in 1/8 inch. See
figure 26. To adjust, follow these steps:
1. Remove the cotter pin and flat washer which hold
the tie rod to the axle bracket. See figure 26.
2. Adjust the tie rod in or out until the wheels toe-in
approximately 1/8". (Dimension “A” should be ap¬
proximately 1/8" less than dimension “B”. See
figure 27.)
s 3. Replace the tie rod into the wheel bracket, and
replace the cotter pin and flat washer.

DECK ADJUSTMENT
Side to Side Leveling
NOTE
Check tire pressure in all four tires
before leveling the deck. Recommended
tire pressure is 12 p.s.i.
If an uneven cut is obtained, the deck may be leveled.
A deck adjustment rod is located on the right side of
the unit. See figure 28.
To adjust the deck, loosen the two hex nuts at the left
rear deck link assembly. Thread the hex nuts up or
down the deck adjustment rod as necessary. Retighten
the hex nuts.
FIGURE 28.
Deck Pitch
The front of the deck should be approximately 1/4" to
3/8" lower than the rear of the deck. Adjust the pitch
as follows.
1. Place the deck in the engaged position.
2. Remove the hairpin cotter and flat washer which
hold the deck lift connecting rod to the front deck
lift assembly. See figure 29.
3. Remove the connecting rod from the deck lift
assembly and thread it in or out of the ferrule as
necessary. See figure 29. Replace the rod.
