No matter what type of lawn mower you own, it's important you keep that blade sharp. Because a sharp blade not only cuts blades clean so grass plants recover quickly, it helps reduce your lawn mowing time.

If you want your lawn mower trimmed smoothly and accurately, it is necessary to follow the sharpening mower blade. To sharpen the blade of a rotary lawn mower, remove spark plug. Pull the spark plug wire from the spark plug to prevent the motor from accidentally starting. Tape or tie it back so it doesn't flop back into contact with the plug.

Then sharpen blade with file. Clamp the blade in a vise and sharpen the cutting edge with a mill bastard file, held at the same cutting angle as before. File until the blade is "butter knife" sharp.

After sharpening a blade, you need to check it balanced. Hang the blade on a nail to check the balance. If one side dips, file a bit more off that side until the blade remains horizontal.

For this vise any steel rod, suitable for diameter and is hung on a blade. If the blade after sharpening outweighed by one of the parties, it is necessary to continue to sharpen the side that outweigh the down, as it is heavier. Unbalanced blade mounted on an electric lawn mower is strictly prohibited, as it can ruin the lawn mower and harm your health.
