Abstract
An agricultural implement trailer for supporting one of a plurality of implements for field usage and transport. The trailer includes a trailer frame supported by transport wheels, and a turntable supporting a hitch member for attachment to a conventional three-point hitch connection on an implement. The hitch member is connected to a horizontally extending arm of the turntable through a linkage assembly including upper and lower link structures defining a parallelogram structure for moving the hitch member from a lowered field-use position to a raised transport position. In the raised transport position, the arm of the turntable supports an implement in cantilever relationship to a pivot member supporting the arm for pivotal movement. During pivotal movement of the arm, the supported implement is pivoted from an orientation with its long axis extending transverse to the longitudinal axis of the trailer to a position where the long axis of the implement is extending parallel to the longitudinal axis of the trailer. In moving the implement to its raised transport position, the center of gravity of the implement is moved forwardly of the pivot member, and the linkage assembly is move…
