LIFT ASSIST SPRING
CAUTION: The lift assist spring
can be under extreme pressure.
Use extreme caution when
adjusting or replacing this spring.
The deck lift assist spring is installed to help
maximize deck performance and minimize
driver fatigue.
To adjust the lift assist spring, lower the
mower deck to the lowest position. Adjust the
spring by torquing the nut until the deck
begins to raise off of the ground and then
back the nut off one turn.
NEUTRAL ADJUSTMENT
Before making any adjustments, be sure to
check the tire air pressure. Incorrect air
pressure can cause the unit to pull to one
side. The correct air pressure is 20 p.s.i. in
the front wheels and 12 p.s.i. in the rear.
1. Stop the engine and remove the ignition
key.
2. Tilt the seat forward.
3. Move the control lever rearward and
release the control lever. This control
lever should return to a position where
the control lever can be swung outward
and lock in the neutral outward position.

4. If adjustment is needed, move the
control lever back to the inward position
and begin to pull rearward. At this
beginning rearward motion the clevis pin
should begin to contact the end of the
slot and start putting pressure on the
spring.
5. If adjustment is needed, loosen the nut
against the yoke and while applying
slight rearward pressure on the motion
control lever, turn the head of the
adjustment bolt in the appropriate
direction until the lever is centered.
6. Move the control lever reward and
release the control lever. This control
lever should return to a position where
the control lever can be swung outward
and lock in the neutral outward position.
STEERING CONTROL LEVER
ADJUSTMENT
When the unit is in motion and one steering
lever is more forward than the other when
driving in a straight line, the steering control
levers are out of adjustment. While traveling,
turn the tracking knob to the left or the right to
increase or decrease the tractor wheel speed
and make the steering control levers equal.
NOTE: The steering control levers need to be
even in both neutral or park.
LEVELING THE DECK
CAUTION: Stop the engine, put
the steering control levers in the
park position and remove the key
from the ignition before
performing any maintenance or
repairs on this unit.
1. Set the front tire pressure to 20 p.s.i. and
the rear tire pressure to 12 p.s.i.
2. Place the mower on a level surface.
3. Raise the mower deck to the transport
lock position and adjust the cut height to
3 inches.
4. Lower the deck back to cut position.
5. Set both of the outside blades to be
perpendicular to the mower as shown in
figure 21.
