Mower Leveling
1.
Position mower on a flat surface. Stop the
engine, set the parking brake, remove the key
and disconnect the spark plug wire(s) from the
spark plug(s).
2.
Check tire pressure of all four (4) tires. If
needed, adjust to 13 psi (90 kPa)
3.
Set anti–scalp rollers to top holes or remove
them completely for this adjustment.
4.
Raise the deck to the transport position (Fig. 41).
Take force off of the two large deck lift springs
by loosening jam nut and front spring nut, in
front of each spring, as far as possible (Fig. 42).
5.
Place two 1-1/4" (35 mm) thick blocks under
rear left and right lower edge of mower. Place
one 1-3/8" (44 mm) block under front center
lower edge of mower. Not under anti–scalp roller
brackets. Lower mower to the 1-1/2" (38 mm)
height-of-cut position (Fig. 41).

position (Fig. 42).

and tighten hardware at the bottom (Fig. 42).

the front chain is tight and front of deck is still
touching block. Tighten front locking nut.
