How To Sharpen Lawn Mower Blades With A Grinder?
If your lawn mower blades are dull, you can use a grinder to sharpen them. First, remove the blade from the mower. Next, clamp the blade in a vise so that you can work on it safely.
Then, use a grinding wheel to sharpen the blade. Start by grinding the beveled edge of the blade. Once the bevel is sharp, move on to the other side of the blade.
Finish by honing the blade with a file or stone to give it a sharp edge.
- Park your lawn mower on a level surface and disconnect the spark plug wire to prevent the engine from accidentally starting while you’re working
- Use a wrench to loosen and remove the nuts or bolts that hold the blade in place
- In some cases, you may need to use a hammer to lightly tap the blade free from the spindle
- Carefully inspect each side of the blade for nicks, cracks or other damage that could cause it to break during sharpening
- If necessary, use a file to smooth out any rough spots on the blade’s cutting edge
- Put on a pair of safety glasses and gloves before starting the grinder
- Hold the blade so that its cutting edge is facing away from you and position it against the grinding wheel at about a 10-degree angle
- Slowly move the blade forward along the length of the grinding wheel several times to sharpen it evenly
- Be careful not to overheat or damage the blade by holding it in one spot for too long
