A large crop material bale handler mountable to a prime moving vehicle operable to retrieve, transport and discharge large crop material bales is provided with a main support frame, a traveling load support with material engaging elements fastened to the lower portion thereof, power lifting apparatus to raise and lower the load support, and grappling members pivotally affixed at a pivot point to the load support and extending outwardly and downwardly therefrom. The grappling member has a material engaging end and an opposing end. The pivot point further overlies the plane of the material engaging elements such that when the grappling member is in the engaged position the material engaging end, in combination with the material engaging elements, exerts a grappling and lifting force on a bale.

A large crop material bale handling means mountable to the three point hitch of a tractor and operable to retrieve, transport and discharge a large crop material bale, the combination comprising: (a) a main support frame extending in a vertical plane generally upwardly away from the ground a predetermined length adjacent the vehicle; (b) a traveling load support means movably mounted to the support frame in a path generally defined thereby and having an upper portion and a lower portion, the lower portion being disposable in a plane generally parallel to the ground; (c) power lifting means to elevate and lower the traveling support means; (d) a pulley and cable multiplier assembly cooperative with the power lifting means to increase the lifting height of the traveling load support means to a height that is greater than the lifting height of the power lifting means alone; (e) material engaging means fastened to the lower portion of the load support means including at least a first pair of elongated tines adapted at a terminal end to penetrate the bale; (f) at least a second pair of elongated tines adapted at a terminal end to penetrate the bale and being attachable to an elongate support member on a first end, the support member being pivotally affixed about a horizontal axis at a pivot point adjacent an opposing second end to the upper portion of the load support means and having a material engaging end, the pivot point further being offset from the main support frame and located so that it is horizontally a greater distance from the main support frame than is the center of the bale and overlying the plane of the material engaging means so that when the second pair of tines and the support member is pivoted downwardly the second pair of tines in combination with the first pair of tines exerts a grappling and lifting force on the bale; and (g) power means to pivot the second pair of tines.
