How to Sharpen a Lawn Mower Blade
During the summer months a typical lawn mower is used quite a bit and will show the signs without regular maintenance. Keeping your lawn mower free from debris and changing the oil as necessary is a great idea. The lawn mower blade should also be changed or sharpened each season.
- Turn the mower on its side or upside down. Use a wrench to loosen the nut that holds on the lawn mower blade. Sometimes it is necessary to use a screwdriver to keep the blade from moving while you are removing the nut.
- Place the blade in a clamp or lay it down where you have a smooth surface to work on. Using a file or battery operated grinder, sharpen the edges of the blade until you see a smooth and shiny metal finish without any pits or knicks. It is easy to just use the existing edge to define where you need to sharpen the blade.
- Make sure the lawn mower blade is balanced correctly by placing your hand in the middle and holding it up. If the blade tips to one side or the other, it will need to be sharpened more on that side. Keep re-working it until the balance is correct.
- Place the mower blade back on the mower and tighten the nut. Make sure you have installed it right side up or it will not work properly.
- Turn the mower over and wipe down any fluid leaks. Start the mower to check that it runs properly and is not shaking .
