ABSTRACT:
An improvement in a self-loading apparatus for picking up and moving a bale of hay having diameters of up to about 3 or 4 feet and longitudinal lengths of up to about 5 or 6 feet. The apparatus is of the type including a main frame member supported on wheels mounted near the end of the main frame. A hitch frame has one end pivotally connected to the front end portion of the main frame, with the other end of the hitch frame adapted for attachment to a tow vehicle. The main frame is adapted to be tilted upwardly about the support wheels when braking devices on the wheels are activated and the tow vehicle is backed up. A pair of load engaging and clamping swing arms are pivotally attached to the respective sides of the main frame. Devices are provided with the main frame and hitch frame for pivotally moving the swing arms away from each other when the main frame is tilted upwardly and, conversely, for pivotally moving the swing arms toward each other when the main frame is lowered by moving the tow vehicle forward while the braking devices on the wheels of the main frame is activated. The improvement of the present invention provides devices for allowing the bale of hay to lie on the ground and be unrolled along the ground by pulling the apparatus forward. Unrolling the bale in such manner provides a long strip of hay for feeding animals.
