Maintenance Instructions
6. Check blade balance by positioning the blade
horizontally on a blade balancer or use a nail
or shaft through the center hole. If either end of
the blade rotates downward, grind (remove)
metal on that end until the blade will balance.
The blade is properly balanced when neither
end drops. Balance of a blade is generally
maintained by removing an equal amount of
material from each end of the blade when
sharpening.

7. Mount the blade with wing tips pointing up into
the housing. For gear driven decks reinstall
the blade, washer, lock washer, and nut. Tight-
en the nut to 60 lb·ft (81 N·m). For belt driven
decks reinstall the spacer (if applicable), blade,
washer, and bolt. Tighten the bolt to 70 lb·ft
(95 N·m).
NOTE: When reinstalling blades on GHS
models, remember, the blades counter-rotate
and the LH and RH blades must not be switched.
Check for proper blade rotation before installing
blades on the deck. Refer to Blade Rotation
illustrations shown in Clogging Checklist in
Operating Instructions for correct blade rotation.

Drive Belts

Raise the body and inspect the condition of the
four (4) belts (3 belts on SD models) every 25 hours
of operation - engine PTO drive, jackshaft drive, hy-
drostatic ground drive, and GHS blower drive. If the
belts show signs of cracking or deteriorating, the
belts should be replaced. Refer to REPLACING/
REPAIRING the Drive Belts in this section.

Mower Deck Gearbox Oil Seals

The mower deck gearbox seals should be inspected
every 25 hours for evidence of oil leaking; particu-
larly the lower oil seal on the blade drive gear-
box. This seal is protected by the trash guard on the
blade hub and seal protector plate on the housing,
but is still vulnerable to seal damage due to operat-
ing in an adverse environment. The mower blade
must be removed for inspection of the seal, so it is
recommended to inspect the gearbox seals when
blades are removed for sharpening. If an oil leak
is noted, the seal should be replaced and the gear-
box assembly relubricated. Refer to LUBRICATION
for Mower Deck Gearbox Lubrication in this sec-
tion.

Spark Plugs

Every 200 hours of operation, remove the spark
plugs, inspect, clean, and reset the gap (or replace
with new plugs). Before removing the spark plugs,
clean the area around the base of the plugs to keep
dirt and debris out of the engine. Clean spark plugs
with a wire brush. DO NOT use an abrasive grit
type cleaner. If the electrodes are burned short or
pitted, replace plugs with Champion
(or equivalent). Check spark plug gap with a wire-
type feeler gauge and set the gap at 0.030 in.
(0.76 mm). Reinstall and tighten to between 18 and
· ·
22 lb ft (24 to 30 N m).

Ignition Wires

Good preventive maintenance calls for complete re-
placement of spark plug wires every two (2) years.

Fuel Lines and Clamps

NOTE: The engine fuel injection system is pressur-
ized and should be serviced by a Walker dealer or
authorized Kohler engine service outlet.
Every year, inspect the fuel supply line from the
tank to engine for deterioration or damage. Also,
inspect the fuel line clamps for tightness. Good
preventive maintenance calls for complete replace-
ment of fuel lines and clamps every two (2) years.

Engine Starter

Yearly or every 500 hours disassemble and clean
the solenoid shift starter. Refer to the Kohler Service
Manual for this procedure or contact an authorized
Kohler engine dealer to perform this service.
