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.
,
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.
