1. What are the benefits of cleaning and maintaining lawn mower blades?

Blades should be cleaned and sharpened before each use. A dull mower blade will not be as efficient, and can potentially cause an unnecessary injury. Additionally, you will probably want to sharpen your blade more often than you would sharpen a serrated knife. Blades should be cleaned after every job to prevent grass build-up that minimizes efficiency.

2. What are the different ways to clean lawnmower blades?

There are simple ways of cleaning blades. Use a scrub brush to remove grass and other debris from the blade. Use a rag or soft brush to wipe the blade clean. Use a solution of water and mild soap; the warm water will help to loosen the grime that’s caked along the blade. Allow the blade to dry completely before storing. It’s important to store the blade in the proper conditions, and it’s best not to leave it stored inside where it can get uneven exposure to sunlight.

3. What are the different ways to sharpen lawnmower blades?

There are two basic ways of sharpening lawnmower blades. Either the blades can be sharpened in the eye of the blade, which is a single bevel that pivots back and forth, or the blades can be sharpened with a jig. The jig method requires a belt sander and a jig. Several blade sharpening companies sell these jigs, and many hardware stores sell them.

4. What are the risks associated with cleaning and maintaining lawn mower blades?

The blades of the lawn mower usually require cleaning whenever they accumulate a lot of grass clippings, which happens when the grass is uncut for a long time.
If left untended, the blades can get dull, which can strain the mower and have you taking too much time to mow the same area. Also, if you don’t maintain the blades properly, the blades could break, causing accidents.

5. How often should I clean and maintain my lawn mower blades?

The manufacturer’s instruction booklet that comes with your lawn mower will help you figure out exactly how often you should sharpen the blades. Five or 6 times a season is a typical recommendation for a good lawn mower. Some mowers require more time to get the blade sharpened, and some mowers require the blade to be honed more often, so check your owner’s manual to find out what the manufacturer recommends.
