Mower Blade Troubleshooting
Learn the common problems with lawn mower blades.
Lawn mower blades can make the difference between a successful mowing experience and an unsuccessful one. You want to make sure your blades are in good working condition, or you’re likely to have problems. Here are some different problems with lawn mower blades, how they’re different, and why they’re bad for your lawn.
• Dull blade. If your blade is dull, you can tell by looking at it. It likely is not in as good of condition as it once was. It’s not sharp. When mower blades are dull, they tear grass rather than cut it. Dull blades also make the engine work harder than it really should. Once a blade becomes so dull that the angle of its original blade is lost completely, you need to be sure to replace it. If you sharpen a blade twice a year, you should be good to go, and your blade will live an optimum life.
• Nicked up blade. If your blade is severely nicked up from running into twigs or rugs repeatedly, and being forced to chop them up, you’ll know. When this happens, your lawn mower will shake violently during use. A nicked up blade won’t cut grass, but simply will tear it, when you’re mowing.
• Twisted blade. If you somehow managed to twist your blade accidentally during mowing, your lawn won’t look right. It will be uneven and unbalanced. In addition, the blade likely is lower or higher than the other blade, and thus may end up chopping right into the ground rather than cutting the grass.
• Nicked up lift wing blade. If your blade has a nicked up wing lift on the end, it will have problems picking up the grass. Thus, the lawn will cut unevenly.
• Good blade. A good blade as a sharp blade and a full lift wing to pull the grass up for cutting. If you sharpen your blades two times a year and check them regularly, you should have no problems.
