Maintenance
NOTE: When tipping the unit or emptying the fuel tank
keep the air cleaner side of engine up. Never tip the
mower more than 90 degrees and do not leave the
mower tipped for any length of time. Oil can drain into
the upper part of the engine causing a starting problem.
Engine
Refer to the separate engine manual for all engine
maintenance instructions.
Maintain engine oil as instructed in the separate
engine manual packed with your unit.
Service air cleaner every 25 hours under normal
conditions. Poor engine performance and flooding
usually indicate that the air cleaner should be
serviced. To service the air cleaner, refer to the
separate engine manual packed with your unit.
The spark plug should be cleaned and the gap
reset once a season. Spark plug replacement is
recommended at the start of each mowing season.
Clean the engine regularly with a cloth or brush. Keep
the cooling system (blower housing area) clean to
permit proper air circulation which is essential to engine
performance and life. Be certain to remove all grass,
dirt, and combustible debris from muffler area.
Deck
The underside ofthe mower deck should be cleaned
after each use to prevent a buildup ofgrass clippings,
leaves, dirt, or other matter. If this debris isallowed to
accumulate, itwilt inviterust and corrosion, and may
prevent proper mulching, discharge, or bagging. The
deck may be cleaned by tilting the mower and scraping
clean with a suitable tool (make certain the spark plug
wire is disconnected).
IMPORTANT:We do not recommend the use of a
pressure washer or garden hose to clean your unit.
Cutting BladeRemoval,Replacement,and Sharpening
When removing the cutting blade for sharpening or
replacement, protect your hands with a pair of
heavy gloves or use a heavy rag to hold the blade.
Remove the bolt and the blade bell support which
hold the blade and the blade adapter to the engine
crankshaft. See Figure 12.

WARNING: Periodically inspect the blade
adapter for cracks, especially if you strike
a foreign object. Replace when necessary.
When sharpening the blade, follow the original angle of
grind as a guide. It is extremely important that each
cutting edge receives an equal amount of grinding to
prevent an unbalanced blade. An unbalanced blade will
cause excessive vibration when rotating at high
speeds. It may cause damage to the mower, and could
break causing personal injury.
