MOWER
CUTTING HEIGHT
NOTE: Stop engine and remove spark plug wire before adjusting cutting height.
Cutting height is adjustable over a 3" range in 1/4" increments. The adjustment is made individually for each
wheel by aligning the wheel's notched adjusting nut along the notched slot in the wheel mounting flange (see
illustration for 0.5" cutting height below). The front wheels should be adjusted first, followed by the rear
wheels, until all are set to the same position and the mower is level.
1. Front wheels
a. Loosen the 1/2" hex nut sufficiently so the wheel can be pulled out approximately 1/4" and the square
adjusting nut can clear the notch.
b. Move the adjusting nut to the desired position. See below to select the appropriate notch position.
2. Rear wheels
a. First raise the rear of the mower and support on blocks.
b. Adjust as for the front wheels.
3. Before using the mower, make sure all wheel are set to the same position and all wheel nuts securely
tightened.
NOTE : Alignment of the square nut with the notched flange is aided by holding the axle bolt with a box
wrench.
