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 position. 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 the tire pressure information in the
Tires
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
transmission’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:
1. Raise the rear of the mower and block with certified
jack stands. The rear wheels need to be able to rotate
freely and clear of all obstructions.
2. Chock the front tires.
3. Unbolt the seat platform from the mower frame.
• Disconnect the mower harness from the seat
switch.
• Bypass the seat switch by connecting the two
mower harness female spade connectors
together. Figure 4-1
• Re-attach the seat platform to the mower frame.
4. Loosen the jam nuts on each end of the steering
control rod assemblies. Figure 4-4
5. Set both steering control levers in the park brake
position. Figure 4-2
NOTE: Both steering control levers need to be in the park
brake position when starting the engine but need to be
moved rapidly out of the park brake position once engine
is started so that the brakes do not fight the
transmissions since they have not yet been adjusted.
This procedure will require that the unit be raised
to allow the drive wheel to rotate.
• Block the mower up off of the ground using
only appropriate vehicle stands (minimum
weight rating of 2000 pound)s. Use in pairs
only. Follow the instructions supplied with
the vehicle stands.
• Do not allow the wheels to come in contact
with the floor or any object that would permit
the unit to propel itself.
• To prevent injury stay clear and exercise
caution when rotating the wheels.
Exercise extreme caution when the transmissions
are engaged.
• Keep hands, hair, clothing, etc., clear of the
cooling fans on top of the transaxles to
prevent entanglement.
