Abstract: A trailer for transporting cylindrical bales includes a central frame portion and two side support members. The central frame portion defines two outwardly inclined upper surfaces for receiving the bales extending outwardly from a central apex. The side support members are pivotally mounted adjacent the sides of the central frame and in initial position provide two parallel V-shaped receptacles for two rows of bales. A third row of bales can be mounted on top of the first two rows in the V-shaped area therebetween. The side support members are latched in the transport position and can be released manually so the first one of the side support members pivots downwardly allowing the first and third rows of bales to be discharged. Subsequently the side support members on the other side is released allowing the second row to be discharged. The side support members can be pivoted inwardly to a highway width which automatically resets the latch mechanism.
