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 hous-
ing as follows:
1. Remove the PTO drive belt from the GHS
blower 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 pul-
ley, then move blade clutch to full “engagement”
position. Both the drive belt and scrubber brake
bar should be clear of blower pulley, allowing
free movement of the blower wheel.
IMPORTANT: With the belt removed, the blower
wheel must spin freely. Any binding or drag-
ging of the wheel is an indication of dirt buildup.
This buildup must be cleaned to avoid abra-
sive wear of the blower blades, excessive
power loss and eventual loss of blower perfor-
mance (clogging).
2. Use a pressure washer or water spray, and
direct the spray inside the blower housing
against the blower blades. Water pressure will
cause the blower wheel to begin to spin, and the
combination of spinning action and water will
effectively 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.
