bladE SharPENiNg

KEEP THE BLADE SHARP FOR BEST MOWER
PERFORMANCE. A DULL BLADE DOES NOT
CUT GRASS CLEANLY OR MULCH PROPERLY.
WEAR PROPER EYE PROTECTION
WHILE REMOVING, SHARPENING,
AND INSTALLING BLADE. ENSURE
THAT SAFETY KEY IS REMOVED.
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.

1. Make sure blade remains balanced.
2. Sharpen the blade at the
original cutting angle.
3. Sharpen cutting edges on both ends of the
blade to keep it balanced, removing equal
amounts of material from both ends.
