Mower Blade Care and Sharpening
BLACK+DECKER B+D Contributor 125 Projects
The blade is an incredibly important part of the mower. If the blade is in poor condition, it can affect your entire lawn. And the negative effects aren’t just related to appearance. A ragged top cut on a leaf of grass opens the grass plant up to disease. That’s why keeping your lawnmower blade sharp is the first line of defense against lawn diseases.
Sharpening your blade is a simple task that should be done at least once every season (and it certainly doesn’t hurt to do it more than once). Before you inspect for nicks or other obvious damage, clean the blade with a wire brush. Serious dents, cracks, or deep nicks in the blade mean it’s probably time for a replacement blade. If you can’t remove the nick fairly easily during the sharpening process, you’ll need to replace the blade.
