Full Answer

The following shows a simple way of sharpening a lawn mower blade.

Step 1: Safety first

Before removing the blades from the lawn mover, remove the spark plug to ensure that it does not start on its own by accident.

Step 2: Make your mark

Make a mark on one side of the blade using spray paint or any other preferred marker before removing the blade. The mark will serve as a guide that will show the proper orientation and side of the blade when its time to reattach it to the motor. If the blade reattaches in the wrong way, it will not be able to cut the grass properly.

Step 3: Examine

Check the blade to see if it is practical to sharpen and use it. If it has too many nicks, curls and damages, it may be time to replace it.

Step 4: Sharpen

If the blade is still usable, secure it on a bench clamp and start working on the blade with the mill bastard file. Lawn mower blade metals are relatively soft and can be sharpened with less than 50 strokes.

Step 5: Reattach

Reattach the blade securely to the motor after sharpening both blades, and then reconnect the spark plug.
