• severe cuts
• tears
• separation
• weather checking
• cracking
• burns caused by slipping.
Slight raveling of belt covering does not indicate failure,
trim ravelings with a sharp knife.
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 the belt will lose power and slip excessively.
Never pry a belt to get it on a pulley as this will cut or dam-
age 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
IMPORTANT: Refer to the Safety section of this manual for
blade handling safety information.
Refer to the Mower Blade Replacement section for blade
removal and installation.
Check the mower blades daily, they are the key to power
efficiency and well groomed turf. Keep the blades 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.
Sharpen the blades following the pattern shown. Touch-up
sharpening can be done with a file.
Figure 4-9
After grinding the blades, check for balance. Blade balanc-
ing can be done by placing the blade on an inverted line
punch or 5/8" bolt. A commercial balancing tool is also avail
-
able through most hardware supply stores.
The blade should not lean or tilt. When spinning the blade
slowly it should not wobble. Balance the blade before rein
-
stalling.
Lay the blade on a flat surface and check for distortion.
Replace any distorted blade.
