Control Lever Neutral Adjustment
Before considering any adjustment, check the tire air
pressure and make certain hydraulic system oil is at
operating temperature. Unequal tire pressure will cause
the mower to drift to one side. Refer to “Tire Inflation
Chart” on page 44.
Fine adjustment to the steering is made with the
adjustable pumplinkage rods located between the control
lever and pump arms. Refer to Figure 3-2.
Neutral is properly adjusted when the control levers are in
the neutral position and the drive wheels are not turning.
If the mower creeps in the neutral position the control
linkage may be adjusted as follows:
1. Raise and block the mower up so the drive wheelsare
off of the floor.

the jack stands. The jack stands should not allow the mower to
move when the engine is running and the drive wheels are
rotating. Use only certified jack stands.
