Abstract: The present invention regards a disc mower trailer for supporting a disc mower for field usage and transport. The trailer includes a trailer frame supported by transport wheels and a hitch member for attachment to a conventional three-point hitch connection on an implement. The hitch member is connected to a crossbar 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. The trailer has been designed to be versatile and apply to most models of three-point lift type disc mowers.
