摘要:
A lawn maintenance device has a transverse center line, a frame, and a power source including an output shaft attached to the frame. The lawn maintenance device further includes a rotating cutting blade. A left side is located on one side of the transverse center line and a right side located on a second side of the transverse center line. A plurality of ground engaging members are attached to the frame enabling movement of the lawn maintenance device along an associated driven surface. The ground engaging members on the left side are located at a first distance from the transverse center line that is different from a second distance that those on the right side are located from the transverse center line. Another example includes ground engaging members on opposite sides of the lawn maintenance device being located at different distances from a central axis of the cutting blade.
