Do not at any time make any adjust­
ment to lawn mower without first
stopping engine and disconnecting
spark plug wire.
CUTTING HEIGHT ADJUSTMENT
An adjusting plate and thumb lever at each wheel posi­
tion provides cutting height adjustment. Each adjusting
plate has nine height positions. Height of cut will be
changed when the thumb lever is moved from one hole
to another. Simply depress the lever towards wheel and
move wheel and lever assembly to desired position.
See figure 19.
Cutting height will be raised as front levers are moved
to the front, and rear levers are lowered. Cutting height
will be lowered as front levers are moved to the rear,
and rear levers are raised. All wheels must be placed
in the same relative position.
For rough or uneven lawns, move the wheels to a posi­
tion which will give a higher cutting height.
