Abstract: An agricultural tool bar having a main beam and a pair of tool supporting side wings which fold forwardly from an extended operating position to a folded transport position. The inner ends of the wings are attached to hinges which are pivoted to a carriage mounted for rolling movement along the main beam. Hydraulic cylinders pivot the hinges relative to the carriage as diagonal links cause the carriage to roll along the beam in a manner to fold and unfold the side wings. Additional hydraulic cylinders act to raise the main beam to the transport position wherein the side wings are wholly supported on the main beam which is in turn supported on a wheel assembly having a sturdy axle underlying it.

Abstract: The invention related to an apparatus for lifting, handling, transporting and unrolling large round hay bales. Preferably said apparatus is employed on the bed of a pickup or truck and includes a frame mounted on the pickup bed with a beam pivotally mounted thereon and with arms pivotally mounted on the beam. The arms have bale penetrating members mounted or fixed thereon. First power actuated means operably pivot the beam in an arc about the rear end of the pickup toward and away from the ground. Second, power actuated means for pivoting the arms and penetrating members about the ends of the beam toward each other in such fashion as to squeeze a bale sufficiently to allow the first power means to lift the bale from the ground, and to pivot away from each other to release the bale. The bale penetrating members are mounted on the arms to allow a bale to be unrolled or distributed.

Abstract: The invention relates to an apparatus for lifting, handling, transporting and unrolling large round hay bales. Preferably said apparatus is employed on the bed of a pickup or truck and includes a frame mounted on the pickup bed with a beam pivotally mounted thereon and with arms slidably mounted on the beam. The arms have bale penetrating members rotatably mounted or fixed thereon. First power actuated means operably pivot said beam in an arc about the rear end of the pickup toward and away from the ground. Second power actuated means slide the arms and penetrating members along said beam toward each other in such fashion as to squeeze a bale sufficiently to allow the first power means to lift the bale from the ground, and away from each other to release the bale. The bale penetrating members are rotatably or fixedly mounted on the arms to allow a bale to be unrolled to facilitate feeding the hay of the bale to animals.
