<p>A bellcrank lever is pivotally connected at its elbow to a tow vehicle such as a tractor. A generally horizontal arm of the bellcrank lever is pivotally connected to the lower front portion of a trailer bed through a universal joint and a centering mechanism. The after end of the bed is supported by two rear wheels. A hydraulically actuated mechanism connected between the vehicle and an upwardly extending arm of the bellcrank lever pivots the bellcrank lever in a vertical plane thereby selectively raising or lowering the front of the bed. The universal joint allows towing and dumping at a considerable angle of lateral tilt of the bed relative to the vehicle and the centering mechanism maintains the trailer in fore and aft alignment.</p>
