A vehicle capable of traveling over uneven ground is disclosed herein. The vehicle includes a body, a frame, a pair of front wheels, an adjustable axle assembly, two pairs of rear wheels, and an actuation system. The body is mounted to the frame, and the frame has front and rear ends with a fore-aft axis extending therebetween. The front wheels are rotatably mounted opposite each other at the front end of the frame, and the adjustable axle assembly is mounted at the rear end of the frame substantially orthogonal to the fore-aft axis. The wheels in each of the two pairs of rear wheels are rotatably mounted opposite each other at the ends of the adjustable axle assembly. The actuation system is capable of mechanically moving the adjustable axle assembly to thereby adjust the fore-aft positions of the rear wheels relative to the frame.
