Abstract
An electrically powered lawn edger (,) having a wire wheel (,) specifically adapted for edging and trench cutting applications. The wire wheel includes pairs of twisted wire brush segments (,) which are held within a hub (,) of the wire wheel. The pairs of brush segments are spaced apart radially around a peripheral edge of the hub to produce evenly spaced gaps (,). The gaps help to prevent the edger from “loading up” with dirt and/or turf when edging or cutting a trench and possibly stalling the edger motor (,). A washer (,) having a key shaped boss (,) keys the wire wheel to an output spindle (,) of the motor to prevent slippage of the wire wheel.
