  • Patent number: 5240365
    Abstract: A bale spike frame for lifting and carrying bales weighing 2,000 pounds or more. The frame members are tied together and reinforced at strategic locations by an integrating plate. The frame is a welded assembly made basically of tubular steel stock having a square cross section and also of some steel plate stock. It has elongated tubular top and bottom members joined to shorter length plate members at their ends to form a rectangular frame. A main bale spike mounting socket is provided in the top frame member and two tubular inserts are provided in the lower frame member for attaching bale stabilizing spikes. An intermediate frame member located directly below the socket extends perpendicularly between the top and bottom frame members and is butt welded thereto. Peripherally welded integrating plates extend from below the bottom end of the intermediate frame member over its front and rear faces and onto the top surface of the top frame member.

  • Patent number: 5044448
    Abstract: Adjustable fitments for attaching any one of a variety of implements to the ends of the lifting and tilting arms of a tractor of the type normally used with front end loaders. Each fitment has a base member and a travelling member movably connected together by a rod assembly, such as a threaded rod assembly, whereby the spacing between the members can be adjusted to coincide with that of the mounting pins of the implement to be attached. Each of the members has a socket for receiving and holding one of a pair of vertically spaced horizontally disposed implement mounting pins. One of the sockets opens forwardly and the other socket opens upwardly. A manually operable latch mechanism is provided on the member which has the forwardly open socket to lock a corresponding implement pin in that socket and thus retain each pin of the pair in its respective socket.

  • Patent number: 4674786
    Abstract: A forklift type assembly for impaling, lifting and carrying a large round bale of hay. The assembly has a backframe with adjustable means for mounting it on the lift mechanism of a small farm tractor. A tubular sheath with a brace on its underside projects from the front of the frame. The rear end of a bale spike, made of a high tensile strength steel rod having a pointed tip, is removably mounted in the sheath. Also mounted on the frame below the sheath and on each side thereof are two forwardly projecting auxiliary bale spikes of reduced length.

  • Patent number: 4288191
    Abstract: A 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 support fingers in cantilevered relation to penetrate and engage the bale. The finger support member is 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 allow continuous tension on the cable and thus prevent any loose unwinding or unraveling of the cable on the power winch.
