ABSTRACT:
A truck has a stowable round bale hauler that includes a beam hinged to the truck rear, and rotated about a horizontal base axis with hydraulic cylinders. Arms journaled at their ends to the beam are pivoted by hydraulic cylinders connecting the arms and the beam. The arms may be pivoted to and from a folded position, and the beam rotated to and from a stowed position, in which positions the arms and beam are contiguous with the vehicle rear. The arms are meshed when folded, with one arm adjacent and between the other arm and the beam to form a substantially flat vehicle rear. Pointed bale stabbers on the arms are proximate the base axis with the arms folded. The arms may be pivoted from the folded position to an open position, where the bale stabbers are distal of the base axis and separated more than a bale length. The arms are pivotable toward each other to an engaged position where the stabbers impale a bale positioned between the arms. Once a bale is impaled by the stabbers, the beam is rotated about the base axis to load and unload bales on a cargo bed of the truck.
