Steering Dampener Adjustment
Refer to Figure 3-4:
The steering dampeners, located under the seat, are
incorporated into the unit to provide some resistance
when control levers are pulled back when backing up.
Make sure steering dampeners are adjusted properly by
moving control levers to the reverse position and
releasing them. If control levers return to neutral position,
they are working correctly. Adjust control levers if they do
not return to neutral. Adjusted as follows:
1.
Place control levers in neutral position.
2.
Adjust left dampener rod:
a. Loosen nut on the left front ball stud.
b. Pull dampener rod towards the front to engage
internal spring in the spring housing.
c. Release dampener rod and allow the internal
spring to bring the rod back to neutral position.
d. Retighten left front ball stud nut.
3.
Repeat step 2 to adjust the right dampener rod.
4.
Check steering dampeners:
a. Move the control levers to reverse position and
release. The control levers should return to neutral
position.
b. Repeat steps 1 through 4 if control levers do not
return to neutral position.

DANGER
For your safety and safety of others, a jacked mower must be
supported properly with jack stands before working under and
around it. Also the wheels on the ground must be chocked on
both sides to prevent the mower from rolling forward or
backward.
3.
Chock front and back side of front wheels to prevent
mower from rolling forward or backward.
4.
Loosen right wheel lug nuts approximately 1/2 of a
turn.
5.
Jack right rear drive wheel off the ground and
securely support the wheel up with a jack stand.
6.
Remove lug nuts and wheel.
7.
Turn ignition switch on.
DO NOT START ENGINE.
8.
Verify both control levers are in park.
Refer to Figure 3-5 & Figure 3-6:
9.
Check gap between actuator lever (#1) and hydraulic
motor (#2). The gap should be approximately 1/16"
(.06").
10. Adjust park brake if gap is greater than 1/8" (.12") or
if actuator lever (#1) touches hydraulic motor (#2):
a. Move right control lever to neutral.
b. Remove cotter pin (#3) and flat washer (#4) from
L-bolt #5. Remove L-bolt from actuator lever (#1).
c. Loosen jam nut (#6) and turn L-bolt (#5) clockwise
two turns to increase the gap and counter
clockwise two turns to decrease the gap.
d. Reinsert L-bolt (#5) in the actuator lever (#1)
mounting hole and temporarily replace cotter pin
(#3).
Do no
t bend cotter pin at this time.
11. Move right control lever to park and recheck gap
between actuator lever and hydraulic motor.
12. Repeat steps 10 and 11 until correct gap is achieved.
If correct gap cannot be achieved, see “Adjusting the
Lever Arm” on page 33.
IMPORTANT:
Use a hydraulic jack, floor jack, or
scissor type jack to lift the mower. Do not use a
handyman jack or bumper jack and don’t jack
against the hydraulic pumps, pulleys, engine floor
plate or muffler.
