ABSTRACT:
A trailer particularly for loading and unloading hay bales has a pivotal loading carriage at its rearward end with loading forks which can be backed under a bale and used to lift the bale onto the trailer by pivotal movement of the carriage. The trailer includes a longitudinally movable carrier with a releasable fork for moving the bale from the carriage toward a forward end of the trailer, and also for unloading bales by reverse movement of the carrier. A winch and cable drive is provided both for moving the carrier lengthwise along the trailer in forward and reverse directions, and for providing pivotal movement of the carriage when the carrier is received therein.
