e) Move lever out of 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 PTO is disengaged.
g) Adjust anti-scalp rollers for Normal Operating Conditions. Place rollers in one
of the positions shown in Figure 7. Rollers will maintain 3/4 in. (19 mm)
clearance to the ground to minimize gouging and roller wear or damage.
For Maximum Deck Flotation, place rollers one hole position lower.
Rollers should maintain 1/4 in. (6.4 mm) clearance to ground. Do Not
adjust rollers to support the deck. Be sure roller bolts and nuts are
installed with the spring disc washer between head of the bolt and
mounting bracket. Torque the 3/8 nyloc nut to 30-35 ft-lbs. (41-47 N-m)
Torque the 3/8-24x2 Gr 8 hex capscrew to 50-55 ft-lbs (68-75 N-m)
Deck Leveling:
a) Position mower on a flat surface.
b) Stop engine, wait for all moving parts to stop, and remove key. Engage
parking brake.
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" (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 8.
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.
