This instructable will lead you step by step to sharpen a lawn mower blade. It is important to keep your blade sharp, for it decreases the time spent mowing as well as helps with overall lawn care. A dull blade will rip the tops off your grass, leaving it vulnerable to disease, while a sharp blade provides a clean cut that helps the plant recover quickly. Depending on the tools you use and how bad the blade is, this can be done in anywhere from 15 to 40 minutes. Sharpening is a simple task, even for a novice. It may take a few times to master however. Yet by doing this by yourself, you will reduce the time to cut your yard, while providing a better cut, as well as keeping your total maintenance cost down.
