ABSTRACT:
A trailer having a frame assembly with front and rear axle beams rotationally coupled to the frame assembly. At least one member interconnects the front and rear axle beams to synchronize movement of the axle beams allowing the front and rear wheels to track one another. In one embodiment a first member connects the right front axle beam with the left rear axle beam and a second member connects the left front axle beam with the right rear axle beam causing the rear axle beam to rotate in the opposite direction of the front axle beam when the front axle beam turns. The push-pull operation of the members cause the rear wheels to track the front wheels.
