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.
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 neutral position and the drive wheels do not
rotate.
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. Insert a 1/4” pin through the opening in the mower
frame and into the steering control lever. This ensures
that the steering control lever is in the neutral position.
Figure 4-1 & Figure 4-2
4. Start the engine and release the park brake.
5. Observe which way the wheel(s) are rotating. If
wheel(s) are rotating forward, loosen the jam nuts on
the pump linkage rods and rotate the rod to lengthen
the steering control linkage until the wheel(s) come to
a stop. Figure 4-3 & Figure 4-4
Repeat for the opposite side if necessary.
6. If wheel(s) are rotating in reverse then loosen the jam
nuts on the pump linkage rods and rotate the rod to
shorten the steering control linkage until the wheel(s)
come to a stop. Figure 4-3
Repeat for the opposite side if necessary.
This procedure will require that the unit 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 supplied with the
vehicle stands.
Keep hands, hair, clothing, etc., clear of the cooling
fans on top of the transmissions. Exercise extreme
caution.
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 procedures should be performed by
trained maintenance personnel only.
