Mower Deck Leveling

Position machine on a flat surface. Preferably
level concrete.
Check the tire pressure in all four tires. Inflation
should be 15 psi.
Place 2x4's on edge under the cutting deck
from front to rear and lower the deck down
onto 2x4's.
Adjust the four lower chain bolts to the center
slots on the deck. FIG - 6 NOTE: Make sure
the lift blocks under the frame are tightly bolted
to the frame.
Check the chains for equal tension. If unequal
adjust lower chain bolt in slot.
Place the deck in the 6" cutting height and
measure from the cutting edge of the blade to
the flat level surface to check the deck cutting
height.

Throttle Lever Tension

Stop engine and remove key.
Throttle lever tension may be adjusted by
tightening the pivot bolt. The pivot bolt secures
the throttle arm to the mounting bracket which
is mounted to the console. Access is gained by
removing the console.
Reverse Spring Detent Adjustment
Stop engine and remove key.
Pull the motion control lever back to the re-
verse position and release the lever. When the
lever stops it should be in line with the neutral
slot, so you can move the lever into neutral slot
with out hitting the side of the console frame.
If adjustment is required put the seat in the rear
most position on the slide, tilt the seat forward,
remove the seat rod from seat frame and fold
seat over forward onto the frame.
On the back of the console where the spring is
fastened, loosen the 3/8" nut and bolt enough
to allow the bolt to slide in the slot. FIG - 7
SETUP AND ADJUSTMENTS
Rotate the motion control lever out into the
neutral slot. While the lever is swung out into the
neutral slot pull it against the back edge of the
neutral slot. Holding the lever adjust the spring
by sliding the bolt in the slot to remove all the
slop and retighten the bolt.
Check your adjustment by repeating the second
step in this process.
If no more adjustment is needed reassemble
the seat rod to the seat frame.
