ABSTRACT:
A lawn mower that is remotely controlled and self-propelled. The lawn mower is propelled by battery powered electric motors that drive a set of wheels that are fixed in relation to the frame. Steering is accomplished through a belt and pulley system generally aligned with the forwardly mounted steering wheels. A battery powered electric motor rotates a center pulley, that in turn rotates pulleys for positioning the steering wheels in relation to the frame. Direction and speed of the mower may be controlled with a two channel radio. Frustro-conical wheel projections may be provided to help cross uneven terrain. Cutting height adjusters for the wheels may also be provided.
