One of the most important working parts of any lawn mower is the blade. It’s one part of the mower that cuts or trims the overgrown grass on your lawn or yard. Its condition is vital to keeping not only your lawn well-cut and clean but also to maintaining a well functioning gasoline or electric powered walk-behind or ride-on lawn mower. When the blades are dull, cracked, clogged up or chipped, the mowers function becomes impaired, thus compromising sensitive components, as well as waste gasoline or electricity.

Today’s lawn mowers are classified in two categories: the reel mowers and rotary mowers. Lawn mowers that use a blade that rotates on a vertical axis are what is known as rotary mowers; those that uses a blade assembly that rotates on a horizontal axis are called the reel or cylinder mowers. The type commonly used for homes is the rotary mower, and is classified into three types: hand-pushed or walk-behind, riding or ride-on and self-propelled.
