Steering Adjustments
Steering neutral adjustment
The mower’s steering has been factory adjusted to eliminate
creeping when the H-Bar steering lever is in the neutral position.
However, should the mower begin to creep, the steering control
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 Tires section for
detailed information.
NOTE: Proper park brake adjustment must be completed
before the steering control 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 H-Bar steering lever is
in the neutral position and the mower does not creep or 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. Remove brake link from lower brake bell crank. Figure
4-1
4. Place the neutral lock/park brake lever in the park brake
position with the engine running. Figure 4-3
5. If rear wheels rotate forward or rearward, loosen the
locking hardware on the turnbuckle assembly. Figure 4-2
6. Tighten or loosen the turnbuckle until rear wheel comes
to a stop. Figure 4-2
7. Retighten locking hardware.
8. Neutral should now be set.
9. Re-attach the brake link to the lower brake bell crank.
Figure 4-1
10. Place the neutral lock/park brake lever in the unlocked
position.
11. With engine running, rotate the H-Bar steering lever
forward, and then into reverse.
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.
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 proce-
dures should be performed by trained maintenance
personnel only.
