The mower blades must be level from side to side. Check the side-to-side level any time you install the mower or when you see an uneven cut on your lawn.

1.Park the machine on a level surface and disengage the blade control switch.

2.Move the motion control levers outward to the neutral position, engage parking brake, stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.

3.Check the air pressure of all four tires. If needed, adjust to the recommended inflation; refer to Checking the Tire Pressure in Drive System Maintenance section. If either one is out of range then follow adjustment procedure.

4.Carefully rotate the blades side to side.

5.Measure between the outside cutting edges and the flat surface (Figure 40 and Figure 41). If both measurements are not within 3/16 inch (5 mm), an adjustment is required; continue with this procedure.
