ABSTRACT:
A self loading multiple bale trailer comprises an elongated trailer frame with a belt conveyor extending from end to end and a lift fork for engagement at the lower periphery of a large round bale at the side of the trailer, for example, by forward motion of a tow vehicle. The lift fork is supported on a frame which is connected by an arm to a sleeve slidable on a verticle shaft and having an hydraulic cylinder for lifting the bale. The sleeve is also rotatable about a vertical axis to swing the lifted bale a half circle from the side of the trailer to a position over the conveyor for deposit thereon. The conveyor is operable to move the deposited bale to a desired position along the trailer, and may also be used to discharge the bale from the rear of the trailer or to reengage the lift fork with the bale. In an alternative form, the bale may be handled by a penetrating spike instead of lift fork legs, which spike may be utilized, in a quarter turn position, in unwinding the bale for feeding.
