Control Lever Neutral Adjustment

Before considering any adjustment, check tire air
pressure and make certain hydraulic oil is at operating
temperature. Unequal tire pressure will cause mower to
drift to one side. Refer to "Tire Inflation Chart" on page
23 and page 50.
Adjustments for neutral position are made to the pump
linkage rods located between the control lever and pump
arms. The pump linkage rods are properly adjusted when
control levers are in neutral position and drive wheels are
not turning.
