Blade Sharpening
KEEP BLADE SHARP FOR BEST MOWER PERFORMANCE.
A DULL BLADE DOES NOT CUT GRASS CLEANLY OR
MULCH PROPERLY.
USE PROPER EYE PROTECTION WHILE REMOVING,
SHARPENING, AND INSTALLING BLADE. ENSURE THAT
THE MOWER IS UNPLUGGED.
Sharpening the blade twice during a mowing season is
usually sufficient under normal circumstances. Sand causes
the blade to dull quickly. If your lawn has sandy soil, more
frequent sharpening may be required.
REPLACE BENT OR DAMAGED BLADE IMMEDIATELY.
When sharpening the blade:
1. Make sure blade remains balanced.
2. Sharpen blade at the original cutting angle.
3. Sharpen cutting edges on both ends of blade, removing
equal amounts of material from both ends.
To sharpen blade in a vise (Fig. R):
1. Be sure the comfort grip handles
2
is released, the
blade has stopped and the mower is unplugged.
2. Remove blade from mower. See instructions for
removing and installing blade.
3. Secure blade
20
in a vise
22
.
4. Wear proper eye protection and gloves and be careful
not to cut yourself.
5. Carefully file the cutting edges of the blade with a fine
tooth file
23
or sharpening stone, maintaining the
original cutting edge.
6. Check balance of blade. See instructions for
bladebalancing.
7. Replace blade on mower and tighten securely.
