How to sharpen a lawn mower blade

To sharpen the blade on your lawn mower:

Remove the spark plug wire.

Tilt the mower up on one side.

Clamp a block of wood to the mower deck to prevent the blade from turning.

Loosen the bolt holding the blade in place with a wrench, turning it counterclockwise.

Mark the blade so you’ll know which side is up.

Sharpen the blade on the beveled side—following the angle of the bevel—using a file, grinder, sharpening stone, or belt sander.

Remove any burs on the flat side of the blade with a file or sharpening stone held flat against the width of the blade.

Put the blade back on the mower with the beveled side of the blade facing up.

Tighten the bolt with a wrench, turning it clockwise.

Turn the mower back upright.

Reattach the spark plug wire.
