d) Insert height adjustment pin into hole corresponding to desired cutting
height and install hairpin cotter. See decals on the sides of deck lift plate.
e) Move lever out of the transport (or 5" (12.7 cm) cutting height) position and
down onto height adjustment pin to mow at selected height.
f) To transport, move lever back up to transport (or 5" (12.7 cm) cutting
height) position.
Note: The foot operated deck lift assist lever can be used to
momentarily lift the deck to clear objects. Be sure that blades are
disengaged.
g) Adjust anti-scalp rollers for Normal Operating Conditions. Stop engine and
remove key. Place rollers in one of the positions shown in Fig. 10. Rollers
will maintain 3/4 in. (19 mm) clearance to the ground to minimize gouging
and roller wear or damage. For Maximum Flotation, place rollers one
hole position lower. Rollers should maintain 1/4 in. (6.4 mm) minimum
clearance to ground. Do Not adjust rollers to support the deck. Be sure
bolt is tightened properly or loss of anti-scalp roller may result.
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 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 Fig. 11.
f) Lower the deck to the 1-1/2" (3.81 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 1-1/2" (3.81 cm) height position. Place locking pliers between the rear
swivel and spring stop to hold the deck in this position. See Fig. 11.
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 four (4) top chain bolts in slots. Check the length of the rod
swivel assemblies. The distance from the outside of the rear swivel to the
outside of the front swivel should be approximately 20-1/4" (51.4 cm).
Adjust the length by turning nuts on either side of the front swivels.
NOTE: Adjust so that all four (4) swivels are free in their holes. This may
cause the measurement to vary slightly from side to side.
i) Adjust the two (2) rear upper chain attachment bolts in the slots to take the
slack out of the chains. (Deck is still supported by wood blocks under the
caster roller brackets). Tighten hardware on the rear chains.
