We recommend sharpening your blade after every 8 to 10 mows.
To get it sharp, remove the blade first. Use a vice to secure the blade, then use a metal file, bench grinder or grinder tip to clean the edge and remove any dents or imperfections.
When you’ve got it sharp enough, you’ll want to make sure the blade is balanced. You can buy a balancer for a few bucks, or simply test its balance on a nail.
As we talked about in a previous post, it’s really important to keep your mower blade sharp so it will cut through grass cleanly. This prevents disease and discoloration.
Obviously, you’ll want to be careful when working with something as sharp as a mower blade. But the work will be worth it, and you’ll see the results in a nicer looking lawn.
