  • 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: 5135343
    Abstract: An article handling device for attachment to the rear of a pickup truck including a rigid main frame having arms separated by a cross member and all lying in substantially the same plane. The cross member has rigidly attached at approximately 90 degrees thereto a leverage pole to rotate the main frame when it is hingedly supported on a bumper mounting base. A floating spear type axle for retaining an article on the main frame is attached thereto near the outer end of each arm by a flexible movement limiting tether. The floating axle when penetrating and thereby retaining an article such as a round bale allows the bale to shift downwardly and rest on the main frame preventing transit damage especially to loosely packed or soft core bales.

  • Patent number: 5129775
    Abstract: An apparatus for lifting and carrying large cylindrical hay bales is formed by a base frame and a lift frame longitudinally interconnected for vertical pivoting movement of the lift frame. One end of the base frame is connected to the three point hitch of a tractor. Hydraulic cylinders pivot the lift frame and a tine-equipped bale supporting frame upwardly. Parallel linkage forming a part of the lift frame maintains the tines of the bale lift frame in upwardly inclined relation to prevent unauthorized movement of a lifted hay bale off the tines. A tilt cylinder on the lift frame permits the bale frame tines to be inclined in a downward direction for depositing the bale at a selected or elevated position with respect to the surface of the earth.

  • Patent number: 5074734
    Abstract: An unrolling device for cylindrical hay bales spikes the bale on its axis and pulls it along the ground to unroll it, when the device is pulled by a pickup truck, tractor, or the like. It comprises a transverse crossbar, two arms hinged at their ends to respective ends of the crossbar, and spikes insertable through the arm ends. The arms may swing out from the bar to a right angle; when both are swung out they lie parallel to one another. The spikes fit through the arm ends to protrude inwardly in the same plane as the plane formed by the crossbar and arms. Thus when set up for use the device has the general shape of a serif capital letter C. In use, the arms are set out on either side of a bale and the spikes are inserted through the arm ends to penetrate the hay bale on its axes. The device is pulled by chains on the crossbar to unroll the bale. When not in use, the device folds into a compact linear shape; the spikes are removed and the arms are folded down.

  • 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: 4341411
    Abstract: A device for assisting in the movement of large cylindrical hay bales is disclosed. The device consists of an elongated bar constructed of spring steel having a point at one end and apertures at either end. The bar is preferably 72 inches long. Connecting members are adapted to be mounted at the apertures at either end of the bar so that when the bar is thrust axially through a bale, a yoke, chains, or the like may be coupled to either end of the bar at the apertures by the connecting members whereby the bale may be lifted, pulled, or skidded by a tractor. The connecting members may include a clevis and pin or bolt, or preferably, an S-shaped connector.
