Deck Leveling:
a)
Position mower on a flat surface.
b)
Stop engine, wait for all moving parts to stop, and remove key.
c)
Check tire pressure in drive tires. Proper inflation pressure for tires is 13 psi
(90 kPa). Adjust if necessary.
d)
Set anti-scalp rollers to top holes or remove them completely for this adjustment.
e)
Raise the deck to the 5" (12.7 cm) height position (also transport position)
and take all force off of the two large deck lift springs by loosening the nuts
at the front of each spring. See Figure 8.
f)
Lower the deck to the 1-1/2" (3.81 cm) height position.
g)
Place a 3/4" (19 mm) thick block of wood under each of the two (2) rear anti-
scalp roller brackets and place one under one of the front center anti-scalp
roller brackets.
h)
Loosen the two (2) top chain bolts in slots in the rear deck lift arms. Loosen
jam nuts and back off the socket head adjusting screws on the bottom of the
arms until the chains are just loose. Turn the socket head adjusting screws in
until slack is taken out of each chain. Tighten the jam nuts. Tighten the chain
bolts in the deck lift arms making sure they don't move while tightening.
i)
Loosen the four (4) nuts which secure the front swivels (two per side) until
the front chains are loose and front of deck is supported by the 3/4" (19 mm)
block. Do not loosen the front chain hardware.
j)
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 3/4" (19 mm) block. Secure front swivel using locking nut
in front of swivel. Repeat for right side.
k)
Recheck that the 3/4" (19 mm) blocks fit just snugly under the brackets and
that the tension on all the chains is approximately equal. Make sure all chain
attachment bolts are tight. Reposition anti-scalp rollers and tighten securely.
