FIGURE 10
ANTI-SCALP ROLLER ADJUSTMENT
5.2.2 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.
Semi-Pneumatic caster tires do not need to be inflated.
d) Set anti-scalp rollers to top holes or remove them completely for this
adjustment.
e) Raise the deck to the 4.5” (11.4 cm) 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 Figure 11.
f) Lower the deck to the 1-1/2” (3.8 cm) height position. Place two 1-5/16”
(3.3 cm) thick blocks under the rear edge of the cutting deck skirt; one on
each side of the cutting deck. Place a 1-1/8” (2.9 cm) block under the
center front edge, but not
under the anti-scalp roller brackets.
g) For units with a socket head adjusting screw and slotted hole in rear deck
lift arm: 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 when pressure is
applied to force rear deck support arms down. See figure 11. Continue to
press down on rear deck support arms and 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 do not move
while tightening.
h) For units without a socket head adjusting screw and slotted hole in rear
deck lift arm: Loosen the two (2) bottom chain bolts in slots at the rear of the
cutting deck. Press down on the rear deck support arm (as shown in Figure
11). While holding the rear deck support arm down, take the slack out of the
rear chains and tighten hardware at the bottom of the rear chains.
i) 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” (2.9 cm)
block. Do not loosen front chain hardware.
