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
(1) mower deck, (2) PTO Coupler [quick discon-
nect], (3) Engine Belt, and (4) PTO Drive belt.
These parts are removed to allow free move-
ment of the blower wheel.
IMPORTANT: With the driveline disconnected,
the blow er 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 abrasive wear of the blower blades,
ex cessive power loss and eventual loss of
blower performance (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 eec-
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.
3. Reconnect the GHS Blower Driveline by revers-
ing the removal procedure.
Transaxle Housing
Keeping the housing on the transaxles clean and
free of obstruction is essential to avoid overheat-
ing the transaxle uid and shortening transaxle life.
The housing should be checked every 100 hours
and cleaned if necessary.
To clean the housing, use compressed air and/or a
pressure washer. Pay close attention to any oily dirt
build up on the transaxle housings. This may be the
result of an oil leak. If an oil leak is noticed, contact
your local Walker dealer.

Transaxle Housing and Cooling Fins
IMPORTANT: In case an oil leak develops on the
input shaft, the cooling fan blowing dusty air and oil
on the transaxle will quickly cover the housing and
pack the cooling ns with oily dirt. If this condition
occurs, contact your dealer immediately to avoid
overheating and dam aging the transaxle.
An additional procedure in maintaining transaxle
cooling is to inspect the cooling fans. Replace the
fan(s) if blades are missing or damaged.
