Rear Cutting Height Adjustment Lever
The height adjuster determines the cutting height of the
mower. The adjuster is located above the left rear wheel.
Casters
(optional)
The front wheel cutting height is determined by the
selection of one of six positions in each caster assembly.
See Figure 9.
To adjust, remove the wing nut from the axle bolt. Slide
the axle bolt and spring washer from the assembly and
select a cutting height. With the spring washer on the
axle bolt reinsert in the square hole desired, through the
wheel assembly and secure with the wing nut previously
removed.
IMPORTANT: All wheels must be placed in the same
relative position.
NOTE: For rough or uneven lawns, move the height
adjustment lever to a higher position. This will help stop
scalping.
Caster Lock
(optional)
WARNING: When operating mower on
hills, front wheels should be locked in the
straight ahead position.
The casters can be locked in a straight ahead position
or can be left to swivel freely. Lift and place the lock pins
