Hi, I'm Mark Sodja. I'm a repair tech at eReplacementParts.com. In this video, I'm going to show you how to sharpen the blade on a push lawn mower. We'll get started by removing the blade from the mower. I've already tipped the mower on its side. Whenever you do that you'll always want to tip it with the carburetor up so you don't drain the oil from the crank case out through the carburetor. I like to use a piece of 2x4 to secure the blade as I remove the blade bolt. There's a number of different ways you can sharpen a mower blade. You could use a hand file or a bench grinder. The method I like to use is a hand held grinder. I'm going to go ahead and clamp the blade into a vice. And whenever you're grinding metal it's a good idea to wear a pair of safety glasses. I'm just

going to hold the grinder at the same angle that's on the blade. Once I get it lined up I'll turn it on and grind one side of the blade. With the first side ground I'll flip the blade around and sharpen the other side. Now that I've sharpened both sides of the blade it's important to make sure that the blade is in balance. The easiest way to do that is to clamp a nail into your vice. Then just set the blade on the nail through the blades center hole and let the blade come to rest. If one side sits a little lower than the other side, that means that side is out of balance and needs a little more metal removed. So you'll want to grind that out a little more. Once you have the blade balanced and sharp it's just a matter of mounting it back onto the lawn mower. And that's how easy it is to sharpen the blade on a push lawn mower.
