d) Make sure that the engine is stopped, and the spark plug wire is disconnected and away from the spark plug to
prevent accidental starting, before going on to Step e below.
e) To test that the band is tight, have someone engage the blade brake (see Photo 3-2 on Page 15) while you try to
turn the spindle pulley by hand in the normal rotating direction.
f) If the band is tight, the pulley spindle should not rotate.

the rod by turning it counterclockwise several turns until the end of the band fits on the rod.

SWIVEL WHEEL KIT
A swivel wheel kit is available as an option on
all TUFFCUT Mowers. Swivel wheels are recom­
mended for use where increased maneuvera­
bility is needed, such as mowing property that
contains numerous trees or other objects. The
wheels can also be locked in a straight-ahead
tracking position for use when mowing rough or
sloping ground.
The swivel wheels are easy to assemble and
can be adjusted to the four cut of height settings
described in Section 5 of this manual. The kit
does not contain the wheels or the wheel mount­
ing hardware, you use your existing front wheels
and hardware to complete the assembly.
Please call or write our Parts Department for
ordering and pricing information.
