Abstract
An improved aircraft towing vehicle includes a base plate, a controller and two drive motors supported by two track assemblies. A pivoting wheel constraint mechanism rests on the base plate and includes a front roller mount, a rear roller mount and a linkage connecting the front roller mount and the rear roller mount. When the rear roller mount is pushed or otherwise urged backward, the linkage causes the front roller mount to pivot upward to confine an aircraft wheel on the base plate. A latch keep is also connected to the base plate for holding the rear roller mount in the backward position and locking the wheel constraining mechanism for moving an aircraft.
