The aircraft tractor is a battery powered airport tug manufactured to push and pull airplanes up to 4,000 lbs in a hanger, airport, or FBO. This airplane mover comes with an easy-on roller cradle that slides effortlessly under the front tire of an aircraft. Once the tire of the aircraft is loaded in the cradle, the cradle has a 5th wheel style turning that allows the aircraft tug to turn a full 180 degrees underneath the wheel of the airplane without turning the wheel or steering mechanism of your aircraft. The lever handle and cable system on the aircraft tractor locks and releases the easy-on cradle when loading and unloading the airplane.
