Grass Buildup In Mower Housing - Walker Model MS (13 HP) Owner's Manual

Maintenance Instructions
1. Inspect accessible cooling fins and clean with
compressed air as needed. If the buildup is
excessive, refer to step 2.
2. Remove the spark plug wire and disconnect the
breather tube on the valve cover. Do not dis-
connect the breather tube from the carburetor
side. Remove the cylinder head shroud by
removing the five (5) bolts, as shown in the
Inspect and Clean Cylinder Head Cooling
Fins photo. Cover the breather tube end and
spark plug boot before cleaning out the cooling
fins. Clean the cooling fins by blowing with com-
pressed air. If the buildup is excessive, use a
piece of wire to probe into the fins for cleaning.
3. Reinstall the shrouds by reversing the preceding
steps. Start the engine and confirm the cooling
airflow.

DANGER
Before raising or removing the mower
deck for cleaning, stop the engine, re-
move the ignition key, and disconnect the
spark plug wire.
Raise the deck lock lever handle on each side of
the carrier frame and pull out to release carrier
frame for tilting action.
Using the carrier frame lift handle, raise deck to
the TILT-UP position and insert the deck hook
into the tilt-up latch on the tractor body.
Deck Secured in Tilt-Up Position
Clean grass buildup underneath the deck using
a pressure washer (and scraper if required).
NOTE: If the buildup is severe, it may be easier
to clean the deck by removing the deck assem-
bly from the tractor and standing the deck
assembly on its "nose".
NOTE: While some degree of material buildup
in the mower deck housing can be tolerated, a
point is finally reached where cutting quality
deteriorates and clogging begins to occur
because of too much buildup on the baffling and
housing.
Lower the deck to the normal operating position
and re-engage the deck lock levers.
