Steering Adjustments
Steering control lever neutral adjustment
The mower's steering has been factory adjusted to eliminate
creeping when the steering control levers are in the neutral posi-
tion. However, should the mower begin to creep, the steering
control lever linkage can be adjusted.
Before considering any adjustment, check the tire air pressure.
Unequal tire pressure will cause the mower to drift to one side.
Refer to tire pressure information in the Tire section for detailed
information.
NOTE: Proper park brake adjustment must be completed
before the steering control lever neutral adjustment can be done.
Refer to the Park Brake Spring Adjustment section for detailed
information.
Fine adjustment to the unit's steering is made with the trans-
mission's control rod.
Neutral is properly adjusted when the steering control levers
are in the park brake position and the transmissions do not
"whine".
If this occurs, the steering control linkage may be adjusted as
follows:
WARNING
This procedure will require that the unit to be raised and
blocked up off of the ground. It is necessary for the
wheels to rotate without coming in contact with the floor
or any object that would permit the unit to propel itself.
Stay clear and exercise caution when rotating wheels to
prevent injury. Use only appropriate vehicle stands, with
a minimum weight rating of 2000 pounds to block the
unit up. Use in pairs only. Follow the instructions sup-
plied with the vehicle stands.
WARNING
Keep hands, hair, clothing, etc., clear of the pulleys on top
of the transmissions. Exercise extreme caution.
WARNING
Untrained maintenance personnel should never attempt to
make any adjustments or repairs to the mower's drive
system while the engine is running. The following proce-
dures should be performed by trained maintenance
personnel only.
1. Shut engine off, place steering control levers in the park
brake position, disengage deck clutch, remove ignition
switch key and disconnect negative battery cable before
doing any adjustments.

6. Place a clamp on the transmission pump arm as shown in
Figure 4-3.
7. Tighten the nuts against steering bushing (Figure 4-4).
Verify that the pump arms are still in the neutral position
8. Move the steering control levers out of the park brake
position and push fully forward, verify that the pump arm
does not bottom out against the stop on the transmission.
Move the levers to the full reverse position and release.
Verify that the levers return near to the neutral position.
9. The steering control levers should be adjusted so that
they align vertically with each other when in the neutral
position (Figure 4-5). Space between ends of steering
control handles to be .50" ±.25". Figure 4-5
10. Check to make sure all tools or obstructions are removed
from under the mower.
