Raise the deck to the 4.5” (11.4 cm) height position and take as much force
as possible off of the two large deck lift springs by loosening the nuts at the
front of each spring. See Figure 12.
f)
Lower the deck to the 1-1/2” (3.8 cm) height position. Place two 1-5/16”
(3.3 cm) thick blocks under the rear edge of the cutting deck skirt; one on
each side of the cutting deck. Place a 1-1/8” (2.9 cm) block under the
center front edge, but not under the anti-scalp roller brackets.

front chains are loose and front of deck is supported by the 1-1/8” (2.9 cm)
block. Do not loosen front chain hardware.

When hardware is loosened, remaining tension in the large support springs
will tend to rotate the deck lift handle up, out of the 1 1/2” (3.8 cm) position.
Press down on the rear deck support arm (as shown in Figure 7) to firmly
return the deck lift handle to the 1 1/2” (3.8 cm) position.

On left side, adjust front swivel using the locking nut behind the swivel until
the front chain is tight and all slack is removed from linkage. Do not lift
front of deck off 1-1/8” (2.9 cm) block. Secure front swivel using locking
nut in front of swivel. Repeat for right side.
