Abstract
A power operated lawn edger includes a power unit comprising an internal combustion engine having a handle portion and being connected to one end of an elongated support boom. A cutter head including a vertically disposed rotating cutter blade is mounted at the other end of the support and comprises a right angle gear drive unit which is driven by the power unit through an elongated drive shaft mounted within the support. The cutter head includes a single adjustable gauge wheel for varying the depth of cut in normal operation of the edger. The gauge wheel is mounted on a support bracket which is pivotally connected to the cutter head. The gauge wheel support bracket is releasably retained in a selected position by a manually adjustable retaining member. A laterally projecting tubular support handle is mounted on the support by a bracket member which provides for moving the handle between a folded position alongside the power unit and a working position.
