Balanced blades give your mowers a smoother cut and less wear on equipment! Compact and easy to use. Inexpensive, nearly universal blade balancer. Designed to fit 99% of all center holes. A dull mower blade doesn't cut grass - it rips and tears, and leaves a less than professional cut. It is widely recommended to sharpen lawn mower blades after each 8 hours of mowing. Craftsman 64988
