FIG. 6
ANTI-SCALP ROLLER ADJUSTMENT
5.2.2 Deck
Leveling:
a)
Position mower on a flat surface.
b)
Stop engine and remove key.
c)
Check tire pressure of all four (4) tires. If needed, adjust to 13 psi (90 kPa).
d)
Set anti-scalp rollers to top holes or remove them completely for this
adjustment.
e)
Raise the deck to the 4.5” 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 Fig. 7.
f)
Lower the deck to the 1-1/2” height position. Place two 1-5/16” thick
blocks under the rear edge of the cutting deck skirt; one on each side of
the cutting deck. Place a 1-1/8” block under the center front edge, but not
under the anti-scalp roller brackets.
g)
Loosen the two (2) bottom chain bolts in slots at the rear of the cutting
deck. Loosen four (4) nuts which secure front swivels (two per side), until
front chains are loose and front of deck is supported by the 1-1/8” block.
Do not loosen front chain hardware.
h)
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”
position. Press down on the rear deck support arm (as shown in Fig. 7) to
firmly return the deck lift handle to the 1 1/2”
position. DO NOT push on
deck lift handle. While continuing to press down,
take the slack out of the
rear chains and tighten hardware at the bottom of
the rear chains.
Downward pressure may now be released.
i)
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” block. Secure front swivel using locking nut in
front of swivel. Repeat for right side.
