16.4 BLADE CLUTCH
The FM mower blade clutch is controlled by an opera-
tor presence control. To engage the blade, depress
the operator’s left hand control lever against operator’s
handle. The blade is disengaged by releasing this
lever.(see fi gure 16-5)
NOTE: The blade clutch must be either fully engaged
for cutting or fully disengaged to bring the blade to
a stop. Do not operate the unit with the blade clutch
partially engaged. Premature belt wear and clutch
failure will result from improper operation of the clutch.
CAUTION: Use extreme care when operating the
blade. Inspect the work area for foreign objects that
could cause damage to the unit or injure the operator
if struck by the blade. Never operate the blade with
bystanders in the work area. Lever operate the blade
without either the discharge defl ector chute or the grass
catcher in place.

Cutting height can be adjusted from 1.5" to 4" by placing
spacers above or below caster spindles. For easiest adjust-
ment change the height on one side at a time. To change
cutting height, tilt the unit back, remove lynch pin, remove
all spacers then set if off to the side, remove caster rig, add
or subtract spacers, reinstall caster rig, place remainder
of spacers if any, then reinsert lynch pin (see fi gure 16-1
through 16-4). Repeat this step on other side.
NOTE: Be sure that the spacers are even on both casters.
Running the deck out of level will result in poor cut quality
and increased belt wear.
