A bench grinder is the fastest way to sharpen a lawnmower blade. Wearing protective eyewear, earplugs, and work gloves, grind the edge of the blade against the spinning wheel. You’ll see sparks, but you’ll be able to sharpen the blade in a matter of seconds.

Can I sharpen my own lawn mower blade?
A drill and sharpening stone that is specifically designed for putting a cutting edge back onto a mower blade is a quicker, easier and more accurate method.
What angle should a lawn mower blade be sharpened?
The factory makes the lawn mower blades with a specific angle. As you grind your blades, you should keep this angle. 30-35 degrees is the most common lawn mower blade angle. It is important to keep this angle in mind when sharpening your mower blades. The angle of the blade should not be too steep or too shallow.
If your blade is too deep, it will not cut the grass as well as it should. Too shallow of an angle will result in a blade that is not sharp enough to get the job done. It is also a good idea to make sure that the blades are sharpened at least once a year.
Do you sharpen both sides of lawn mower blade?
If you want the longest lasting edge on the blade, you should always sharpen from the top side of the cutting edge. The file only cuts in one direction on the push stroke, so you’ll feel it bite into the steel on your other side. Use a sharpening stone to polish the edge.
You can use any stone you like, but I like to use a stone that has a rounded edge, like a diamond. This will make it easier to get a good, even edge with the file. If you don’t have one, you can buy one at a hardware store for about $10.
The stone should be placed on a flat surface, such as a workbench or countertop, so that it can be held in place with a pair of pliers or a screwdriver. When you feel a little bit of resistance, it’s time to move on to the next step.
How do I know if my mower blade is dull?
A dull blade can make your lawn appear yellow, brown and raggedy. A dull lawnmower blade can pull up portions of the grass because it pulls on the entire plant instead of slicing it up. If you have a lawn mower that has a blade that is dull, you may want to consider replacing it with one with a sharper blade.
How many times can you sharpen a lawn mower blade?
Most home owners only need to sharpen their blades twice a year. You might need to sharpen your blades more often if you mow over sticks or rocks.
