ABSTRACT:
This invention relates to a combined vehicle-mounted carrier and dispenser for a cylindrical hay bale of substantial size and weight. An elongated finger-support member is pivotally mounted on the bed of a pick-up truck, a tractor hitch or other vehicle. The finger support member is T-shaped to retain a plurality of movable support fingers in cantilevered relation to penetrate and engage the bale. The finger support member is pivotally attached to a base member which is mounted on the truck bed. A power winch is located on said base member having a cable connected to the free end of the central arm member of the T-shaped finger support member. Tensioning means comprising a pair of aligned leaf springs is mounted between said pivotal finger support member and said fixed base member to maintain continuous tension on the cable and thus prevent any loose unwinding or unraveling of the cable on the power winch. The leaf springs further function to assist positive control of pivotal movement of the finger support member between its lowered and raised positions, both when loaded and unloaded. The mechanism includes a pair of similar U-shaped arm members with each arm having coaxially aligned pivotal leg portions and pointed tip leg portions adapted to axially penetrate the bale for its unrolling upon delivery to a feeding location.
