ABSTRACT:
This invention relates to a heavy duty commercial lawn edger apparatus utilized to achieve a new and novel contoured edge cut between adjacent portions of a grass area and a concrete or curb area. The lawn edger apparatus includes a main support base assembly directed by a main handle and control assembly and having a main power assembly mounted thereon. The main power assembly is connectable through a belt and pulley drive assembly to selectively drive a main edging and cleaner assembly. The main edging and cleaner assembly includes a heavy duty blade assembly; a main brush assembly mounted adjacent the main blade assembly for surface cleansing purposes; and an adaptor cutter assembly releasably connected to the main blade assembly to achieve unique shapes in the contoured edge cut. The main blade assembly includes a thick main blade member having spaced cut out sections to achieve a novel cutting feature of this invention. The adaptor cutter assembly includes various embodiments of a contour cutter assembly to achieve a right angular or contoured shape in the contoured edge cut and to sever the grass adjacent thereto. The main support base assembly includes a front guide wheel assembly which can be vertically and angularly adjustable to create a biasing effect of the main edging and cleaner assembly against a vertical surface of the concrete or curb member being edged. The main edging and cleaner assembly includes a cover shield assembly to enclose the rotating blade, brush, and cutter assemblies and operable to receive and direct the debris and cut grass rearwardly, laterally, and downwardly for a safety feature plus eliminating subsequent clean up operations for the lawn edger apparatus operator.
