Lawn Mower Blades

The most crucial aspect to any lawn mowing device is the blade. If the blade does not function then the lawn mower does not function. The lawn mower blade needs to be in tip-top condition for the grass to be cut cleanly. The cleaner the cut, the better the appearance of your lawn but also the healthier your lawn will be. Blunt blades can damage grass by failing to cut cleanly and this makes your lawn prone to disease and also needs more attention to ensure survival.

Difference is sizes

The difference in blade sizes comes down to the size of the lawn mower you choose. The blade of a low output push mower is smaller than the blade of a lawn tractor. The size of blade is determined by the size of the deck of the lawn mower. In smaller push mowers the blades are approximately 20″. In riding mowers you are looking at blades at least twice that size.

How to look after your lawn mower blades

Looking after your lawn mower blades is like looking after a set of kitchen knives. Regular sharpening will maintain their edge. The more you neglect them the more work you need to do to bring them back to life. The longer you leave sharpening the blades the more susceptible to lasting damage the blades are.

Your lawn mower blade needs to be sharpened to maintain optimum cutting. Grab a file to sharpen the blade. Hold the file at a 45 degree angle to the blade and stroke the blade along the length of metal. Start close to you and move the file away from the body. The 45 degree ensure that the bevel (angle) is maintained. The sharpness of this angle dictates the sharpness of the blade. The closer to 45 degrees the cleaner the cut.

Bear in mind that some lawn mower blades may need to be sharpened by the company or by a professional in order to keep their warranty. Always read the manual or check with the manufacturer before attempting to sharpen your blade.
