Abstract
Abstract Cutting blades are pivotably secured to a series of staggered, radially projecting arms extending from a tubular body. A centrally apertured plate is secured to one axial end of the body to receive an adapter bushing for mounting the body on different size, rotatable lawn edger shafts. Rotation of the edger shaft extends the blades by centrifugal force to cut a relatively wide path between a lawn and a boundary such as a sidewalk.
