Blade sharpening
Keep blade sharp for best mower performance. A dull blade
does not cut grass cleanly. Use 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.
Note: 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.

tooth file (23) or sharpening stone, maintaining the angle
of the original cutting edge. Check balance of blade. See
instructions for blade balancing.
Replace blade on mower and tighten securely.
Blade balancing (fig. W)
