GHS Blower
Normally, the GHS blower operates with no mainte-
nance or cleaning. However, when mowing
grass
that is dirty and damp
(especially certain spring
time mow ing conditions), a deposit of dirt may ac
cumulate 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 wires.
Wear goggles or face shield.
1. Disconnect blower from driveline by removing
the following:
(1) Mower Deck
(2) Engine Drive Belt*
(3) PTO Drive Belt*
* Refer to
REPLACING/REPAIRING
the
Drive
Belts
in this section.
2. Secure the PTO U-joint Tube Assembly in the
horizontal position by installing the PTO Saddle
Bracket (P/N 5275-6) as shown. This configura
tion is set up to allow free movement of the blow
er wheel.
NOTE:
The saddle bracket is ordered as a ser
vice part.
IMPORTANT:
With the driveline disconnected,
the blower wheel
must spin freely.
Any binding
or dragging of the wheel is an indication of dirt
buildup. This
buildup must be cleaned
to
avoid abrasive wear of the blower blades,
excessive power loss and eventual loss of
blower performance (clogging).

3. 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.
4. Reconnect the GHS Blower Driveline by revers
ing the removal procedure, and remove the
saddle bracket before installing the mower
deck.
