Abstract
An elongated trailer has a frame with longitudinally extending frame members connected by front and rear cross frame members, and a pair of wheels are pivotally connected to opposite ends of each of the front and rear cross frame members. A steering system includes a front steering crank member connected to a tow bar and supported by the front cross frame member for pivotal movement on a vertical axis, and a rear steering crank member is supported by the rear cross frame member for pivotal movement on a vertical axis. A set of tie rods pivotally connect the front and rear crank members to the corresponding front and rear wheels. An elongated link member or rod connects the front and rear crank members and extends longitudinally of the frame substantially above the bottom surfaces of the frame members to protect the steering system from projecting objects on the ground.
