Power-driven edger with on-center wheel

摘要

An electric edger having a transversely mounted electric motor for rotationally driving a vertically oriented cutting blade. The edger is supported by a pair of auxiliary rear wheels and a large on-center front or main wheel that is journalled to a hub that is mounted directly to the exterior of the motor field casing so that the wheel rotates about the motor. The rotational axis of the on-center wheel is substantially aligned with the cutting blade axis and the plane of the wheel is substantially aligned with the center of gravity of the motor subassembly. This configuration, together with the large diameter of the wheel, improves the balance and maneuverability of the edger, particularly around irregularly shaped borders and over uneven terrain, without increasing the overall dimensions of the unit.
