A flatbed lead trailer is conventional except that it includes a articulating deck elevator mechanism for supporting and reversibly elevating the front end of the trailer. The articulating deck elevator mechanism is longitudinally symmetrical about its longitudinal center axis and includes spaced longitudinally extending hoisting arms each pivotally coupled at a proximal end to the deck, and a pair of spaced extensible members each preferably a hydraulic ram pivotally coupled at its upper end to the deck and at its lower end to the hoisting arm. The distal ends of the hoisting arms are provided with bushings or bearings in which a distal roller is rotatably mounted. The hydraulic rams are operable to pivot the hoisting arms between a lowered position and a raised position. In the lowered position, the front end of the trailer contacts the ground, permitting a tractor to drive onto the trailer for transport of the tractor atop the trailer or its pup.
