ABSTRACT:
A large round bale handling apparatus has a mobile frame with a pair of laterally-spaced longitudinal beams which can receive and support large round bales end-to-end in a row with their axes generally aligned and extending parallel to the beams. The apparatus also has a bale pickup mechanism, a bale pushing mechanism, and a bale unloading mechanism, each mounted to the mobile frame. The bale pickup mechanism is pivotally mounted adjacent the front and along one side of the mobile frame for movement between horizontal bale-engaging and upright bale-discharging positions. The bale pushing mechanism is supported at the front end of the mobile frame for reciprocal movement through rearward working and forward return strokes to move each bale deposited onto the forward portion of the frame by the pickup mechanism through a distance greater than the axial length of the bale allowing transfer of succeeding bales form the pickup of the frame and rearward movement thereof until a row of end-to-end bales has been accumulated on the longitudinal beams of the frame. The bale onloading mechanism is pivotal between lowered and tilted raised positions about a longitudinal axis extending parallel to and along one of the longitudinal beams for lifting and rolling off one side of the mobile frame over the one of the longitudinal beams thereof the row of accumulated bales to concurrently discharge the bales from the longitudinal beams of the mobile frame.
