Lubrication

WARNING: Always stop engine, discon-
nect spark plug, and ground against
engine before cleaning, lubricating or
doing any kind of maintenance on your
machine.

Blade Control Handle and Drive Clutch Control:

 

Lubricate the pivot points on the blade control handle 
and the drive clutch control at least once a season with 
light oil. These handles must operate freely in both 
directions. See Figure 10.

Wheels:

 Lubricate the wheels at least once a season 

with light oil (or motor oil). If the wheels are removed for 
any reason, lubricate the surface of the axle and inner 
surface of the wheel with light oil.

Chute Deflector or Mulching Baffle: 

Lubricate the 

torsion spring and pivot point periodically with light oil to 
prevent any rust or binding. 

Engine:

 Follow the separate engine manual packed 

with you unit for lubrication instructions.

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 of the mower deck should be cleaned 
after each use to prevent a buildup of grass clippings, 
leaves, dirt, or other matter. If this debris is allowed to 
accumulate, it will invite rust 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 Blade Removal, 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 11.

Remove the blade and the adapter from the 
crankshaft.

Figure 11

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.
