GHS Blower
Normally, the GHS blower operates with no mainte-
nance or cleaning. However, when mowing
grass
that is dirty and damp
(especially springtime mow-
ing), a deposit of dirt may accumulate inside the
blower housing, causing wear and binding of the
blower wheel. When operating in these conditions,
inspect the blower frequently for dirt buildup.
NOTE:
A visual clue of binding of the blower wheel
is the blower
blade tips are polished
from rubbing
on dirt.
When a dirt deposit is found, use a high pressure
washer or water spray to clean the inside of the
housing as follows:
DANGER
Before attempting to wash the blower, stop
the engine, remove the ignition key, and
disconnect the spark plug wire.
1. Remove the PTO drive belt from the GHS blow-
er pulley as follows: Move the blade clutch (in
direction of engagement) far enough to relax
the belt scrubber brake without tightening the
PTO drive belt. Roll the belt off of the blower
pulley, then move blade clutch to full “engage-
ment” position. Both the drive belt and scrubber
brake bar should be clear of blower pulley, al-
lowing
free movement
of the blower wheel.
IMPORTANT:
With the belt removed, the blow-
er wheel
must spin freely.
Any binding or drag-
ging of the wheel is an indication of dirt build-
up. This
buildup must be cleaned
to avoid
abrasive wear of the blower blades, ex cessive
power loss and eventual loss of blower perfor-
mance (clogging).
2. Use a pressure washer or water spray, and di-
rect the spray inside the blower housing against
the blower blades. Water pressure will cause
the blower wheel to begin to spin and the com-
bination of spinning action and water will effec-
tively wash the inside of the housing. Spray
may be directed against the blower blades ver-
tically and horizontally to cause rotation in both
directions for thorough washing action.
Wash
blower until the blower wheel spins freely
in
both directions.
