A tug operable to move an airplane. The airplane includes an airplane wheel, the tug may include a frame, a wheel supporting the frame for movement over ground, and a retainer assembly supported by the frame and engageable with the airplane wheel to connect the tug and the airplane. The retainer assembly may be configurable in a loading condition, in which the airplane wheel is loaded onto and off of the tug, and in a retaining condition, in which the airplane wheel is retained on the tug. The retainer assembly may include a first wall engageable with a front portion of the airplane wheel to limit movement of the airplane wheel relative to the tug in the direction of the first wall, and a second wall positionable in an engaging position, in which the second wall is engageable with a rear portion of the airplane wheel to limit movement of the airplane wheel relative to the tug in the direction of the second wall, and in a ramp position, in which the second wall provides a ramp portion, the airplane wheel being movable on the ramp portion onto and off of the tug.
