General engine maintenance
Detailed instructions and recommendations for break-in
and regular maintenance are specified in the respective
Engine Owner’s manual. Please refer to this manual for
engine servicing, lubricating oil levels with quality and
viscosity recommendations, bolt torques, etc. The engine
warranty is backed by engine manufacturer. Special
attention should be paid to applicable data which will not be
duplicated here.
Belt replacement
Figures 4-7, 4-8 and 4-9 show diagrams and descriptions
of the unit’s belt drive systems.
Inspect these belts frequently for wear and serviceability.
Replace a belt that shows signs of severe cuts, tears,
separation, weather checking and cracking, or burns caused
by slipping. Slight raveling of belt covering does not
indicate failure, trim ravelings with a sharp knife.
NOTE:
When replacing the traction drive belts, replace in pairs
only.
Inspect the belt pulley grooves and flanges for wear. A
new belt, or one in good condition, should never run against
the bottom of the groove. Replace the pulley when this is
the case, otherwise belt will lose power and slip excessively.
Never pry a belt to get it on a pulley as this will cut or
damage the fibers of the belt covering.
Keep oil and grease away from belts, and never use belt
dressings. Any of these will destroy the belt composition in
a very short time.
Mower blade maintenance
Check the mower blades daily, they are the key to power
efficiency and well groomed turf. Keep them sharp, a dull
blade will tear rather than cut the grass, leaving a brown
ragged top on the grass within a few hours. A dull blade
also requires more power from the engine.
Replace any blade which is bent, cracked or broken.
WARNING:
Never attempt to straighten a bent
blade by heating, or weld a cracked or broken
blade as the blade may break and cause serious
injury.
DANGER:
Never work with blades while
engine is running or deck clutch is engaged.
Always place transmission handle in the neutral
position, disengage blade engage lever, place
thumb lock levers in the park brake position, turn
engine off and remove ignition switch key.
Block up mower when you
must work under it.
Wear gloves when handling blades. Always
check for blade damage if mower strikes rock,
branch or other foreign object during mowing!
