When your lawn mower isn't making the cut, all it needs is a minor tune up. Sharpening your lawn mower blade is easier than you think, and takes a fraction of the time it takes to actually mow your lawn. Follow our quick and easy guide to make your lawn mower work like new.
Editor's Tip: Not sure if your blade needs sharpening? Most experts recommend sharpening mower blades twice a season. If your lawn isn't looking as crisp as it once did, chances are it's time to sharpen the mower blade.
Disconnect the spark plug or unplug the mower. Turn the mower over and remove the nut that attaches the blade to the motor. Then, remove the blade from the mower.
Stabilize the blade in a vise and use a medium file or a sharpening power tool to smooth out imperfections along the blade edge (at the ends of mulching blades). Don't try to hone a sharp edge.
After you smooth the cutting edge on both halves of the blade, check to see if the blade is balanced. If not, remove more metal from one of the halves until the blade does balance.
When the blade is correctly balanced, put the mower blade back onto the mower using a wrench. Be sure to tighten the nut securely back into place.
