Some people do a great job of performing the proper, regular maintenance of their lawn mowers. But some forget one crucial point: lawn mower blade sharpening. Why is it so important? Well, not only will you be able to mow more quickly without putting undue stress on the mower, but you?ll also have a healthier lawn if you keep the lawn mower blade sharp. A dull blade doesn?t cut the grass; it rips and pulls the grass. That weakens the grass and promotes lawn disease. So you want to sharpen the blade at the start of the season and then once a month. If you mow often or have a lot of territory to cover, you?ll need to sharpen the blade more often.
Whether you're working on a chipper or the lawn mower, take extra care with equipment that cuts and grinds material. So if you want to try sharpening the mower blade of a push mower yourself, the No. 1 rule you must follow is to ensure the lawn mower cannot start while you are removing the blade or putting it back on. The easiest way to do that is to remove the spark plug. Tip the mower, keeping the side with the carburetor up to keep the oil from leaking. If the gas cap has air holes, keep a pan and some cloths nearby to clean up any spills, and be sure to properly dispose of the material.
