Abstract: A trailer bed includes on opposite sides thereof upstanding hollow posts in which downwardly extending hydraulic cylinders are positioned to engage laterally inwardly extending wheel axels thereby extension of the cylinders raises the bed relative to the ground. The tongue of the trailer includes a pair of vertically spaced parallel members extending forwardly and connected to a hitch plate with a hydraulic cylinder carried on the tongue being connected to the parallel members for raising and lowering the tongue relative to the hitch plate adapted to be connected to the drawbar of a tractor. Spring-loaded actuator pins provided for locking the axels to the posts and locking the parallel members to the tongue for maintaining the trailer bed in a raised position. Actuating means extend from the locked pins to the front of the trailer for operation by the operator of the tractor.
