A trailer for transporting a crop harvester header, such as a forage harvester header, after it has been separated from a transport vehicle such as a self-propelled crop harvester. The trailer includes an elongated frame having forward and rearward ends. A first wheel assembly is mounted at the forward end of the frame and a rear wheel assembly is mounted at the rearward end of the frame. The forward end of the elongated frame is hingedly secured to the front wheel assembly so as to be selectively movable between an upper transport position to a lower loading position. The rearward end of the elongated frame is hingedly secured to the rear wheel assembly so as to be selectively movable between an upper transport position to a lower loading position.
