NOTE: When anti-scalp rollers are placed in these positions, reduced deck
floatation will result.
4.3.2 Deck Leveling:
a) Position mower on a flat surface.
b) Stop engine, wait for all moving parts to stop. Engage parking brake.
c) Check tire pressure in drive tires.
For Units Equipped With Turf Tires: The drive tires should be inflated to
13 psi (90 kpa).
For Units Equipped With Bar-Lug Tires: The drive tires should be inflated to
9 psi (62 kpa).
d) Fully extend the cylinder to raise the deck as high as it will go (this is also the
transport position). Note the position of the cut height indicator. Adjust the
indicator if necessary so that the indicator is pointing to the 5" cut height mark.
See Figure 13.
e) Lower the deck to the 4" cut height position and remove ignition key. Orient the
blades longitudinally with respect to the machine. Stand a wooden block
approximately 5" long next to the front blade tip of the center blade; mark the
location of the blade tip on the block. Remove the block and measure height on
the block, it should be 4". Repeat this process for the rear blade tip of both the
left and right blades, those should measure 4-1/4" to give the recommended 1/4"
positive rake. See Figure 14.
f) If adjustments are necessary, four socket head 5/16-18 x 1-1/4 screws have
been provided in the literature bag. Install these screws into the deck lift arms
until they touch the hex head deck chain screws. Loosen the top chain screws in
slots in the deck lift arms (See Figure 15). Turn the socket head screws to move
