  • Patent number: 4318448
    Abstract: A lightweight, yet heavy duty, self-contained towing vehicle of relatively small size and designed for maximum maneuverability in confined quarters, driven by a multi-speed, electric motor in which the forward speed is greater than the reverse speed. The steering control handle is pivotally mounted in cooperative relation to the drive wheels to act as a manual differential clutch thus facilitating maneuverability and convert the vehicle from power driven to freewheeling and even to somewhat control the speed of the vehicle. A clamp-on bracket is pivotally mounted about a vertical axis on the front end of the vehicle and selectively adapted to engage and hold a conventional tow bar of the type provided with the aircraft. The vehicle is battery powered and has two electrical systems, a first which drives the vehicle forwardly at one speed and a second, which drives the vehicle in reverse at a second slower speed.
