Blade Sharpening
KEEP BLADE SHARP FOR BEST MOWER PERFORMANCE. A
DULL BLADE DOES NOT CUT GRASS CLEANLY.
WARNING: Use gloves and proper eye protection
while removing, sharpening, and installing blade.

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:
•
Make sure blade remains balanced.
•
Sharpen blade at the original cutting angle.
•
Sharpen cutting edges on both ends of blade, removing
equal amounts of material from both ends.
