  • Self powered landscaping attachment for vehicle
    Patent number: 7665233
    Abstract: A snowplow or other landscaping implement for mounting by a single point attachment such as a trailer hitch receiver on a host platform or the rear of a vehicle. The implement includes a main battery for intermittently powering a mechanical actuator or blade lifting mechanism where the functions are remotely controlled by the vehicle or host platform operator controlling at least one solenoid for switching on main battery power when needed. There is also a main battery trickle charging system connectible for power to an electrical circuit on the host platform or vehicle through a connector, and configured to draw only a limited level of current only when the main battery needs it and the source electrical circuit can readily provide it.
