ABSTRACT:
A trailer for transporting round bales has two bale support cradles one on each side and pivotal about an axis along the side between a first lifting position in which the cradle extends outwardly and a second transport position in which the cradle is located on the support area for transport on the frame. Each cradle has bale support rails carried on polygonal axially spaced rings defining a cylindrical chamber so that a bale can be lifted by rails on each side from the ground rotated onto the frame for transport and rotated back to its initial position with its flat spot back on the ground. A backstop member can be moved from a first position closing the rear end to allow the bales to be discharged from the rear end by forward movement of the trailer.
