Abstract
Abstract An edger attachment for a powered lawn mower has a blade adjustably, rotatably mounted on the mower frame and rotated by a power take-off connected to the mower power source. The blade is mounted on the frame for vertical adjustment by a remote control assembly associated with the mower handle. The mower wheels arranged on a side of the frame opposite the side on which the blade is mounted each have a further wheel pivotally mounted thereon for leveling the mower frame on a curb, and the like, and a disk plate is mounted adjacent and associated with a wheel disposed on the same frame side as the blade for guiding the mower frame while edging. The blade is formed by a blade body constructed from a resilient material having a plurality of parallel wires embedded therein for reinforcing same.
