Can You Sharpen A Lawn Mower Blade Without Removing It?

You can tell when a mower blade needs to be sharpened by looking at it. If there are visible nicks, dents and small chips, the blade needs some attention. Aim to sharpen your blades every 25 hours of runtime or twice in the mowing season.

There are a few ways that you can sharpen your lawn mower blade without removing it. One way is to use a file. You will want to use a medium-grit file and make sure that you are moving the file in the same direction as the blade is spinning.

Another way to sharpen your lawn mower blade without removing it is to use a bench grinder. You will want to use a medium-grit wheel and move the blade back and forth across the wheel until it is sharpened.


It is always best to remove the blade from the mower before sharpening it. This ensures that you can sharpen it evenly and avoid damaging the mower.
