Patent ID: 6938699

Claim:
A powered landscape edging apparatus comprising: a power unit having a frame supported for movement over the ground by a pair of wheels and an engine providing a source of rotational power; an implement mounting mechanism pivotally supported by said frame for pivotal movement about a generally vertical axis of rotation, said implement mounting mechanism including a support arm extending generally orthogonally to said axis of rotation; an edging implement having a mounting arm connected to said support arm to be pivotally movable therewith, said mounting arm having a transverse portion to position said edging implement outboard of said frame, said edging implement including a generally vertically oriented disk member rotatably mounted on said mounting arm configured to position said disk member adjacent one of said wheels, the pivotal movement of said support arm and said mounting arm positioning said disk member through a range of movement including a positioning of a cutting plane of said disk member parallel to a direction of travel of said landscape edging apparatus and at an angle to said direction of travel, said transverse portion of said mounting arm extending to a longitudinal portion, said longitudinal portion extending rearwardly from said transverse portion to position said disk member outboard of said one wheel said longitudinal portion including a yoke defining a generally transversely extending pivot axis for said longitudinal portion to permit a vertical movement of said disk member relative to said transverse portion of said mounting arm; and a drive mechanism operatively interconnecting said engine and said disk member to power the rotation of said disk member drive mechanism interconnecting said power output shaft and said work implement, said axis of rotation coinciding with said power output shaft so that said work implement can pivot about said axis of rotation without disrupting the transfer of rotational power from said engine power output shaft.
