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” (2.54 cm) height position. Force the left rear deck
support arm downward about 1/4” (6.4 mm) to get the deck to rest at the 1”
height position. Place locking pliers between the rear swivel and spring stop to
hold the deck in this position. See Figure 7.
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 snug under the brackets and that
the tension on all the chains are approximately equal. Make sure all chain
attachment bolts are tight. Reposition anti-scalp rollers and tighten securely.

l) Raise deck lift lever to the 5” (12.7 cm) cutting height position See Figure 5.
Adjust spring compression until proper distance is obtained between the two
large washers (See Figure 8). Adjustment is made by turning the nut at the
front of each spring (clockwise will shorten the spring, counter-clockwise will
lengthen the spring). Lock in position with jam nuts.
NOTE: When above adjustments have been made, the front of the
deck will be slightly lower than the rear of the deck.
