  • Patent number: 10327371
    Abstract: A drill attachment for removing weeds and the like from the ground, which has a body with a shaft protruding from the center and at least two prongs protruding from the opposite side of the body. The free end of the shaft is placed into the chuck of an electric drill, and the prongs are forced into the ground around a weed. The user operates the drill, thus spinning the prongs around the weed. The prongs entangle the weed's roots and bore a small hole in the ground, allowing the user to easily remove the weed. The prongs are then placed into the ground close to the hole, and the drill is slowly operated, thus refilling the hole. The device has a plurality of edges and corners that allow the operator to shear weeds and the like that become entangled on it.

  • Patent number: 10327375
    Abstract: A folding toolbar for an agricultural implement. A unitary flex hinge structure connects adjacent sections of the toolbar and provides a dual pivoting function. The flex hinge pivots about a first pin connected to a first section and is in pivotal connection about a second pin connected to a second section, the first and second pins defining axes that are orthogonal to each other. The unitary flex hinge further includes a lug plate that defines a mid plane along which a force may be applied. The mid plane and the axis of the first pin may be coplanar to reduce bending moments about the flex hinge relative to conventional arrangements where the axis of a hinge pin is offset relative to the plane in which the force is applied. The first pin may be mounted to a hinge mount that is mounted to lug plate for a compact design.

  • Patent number: 10278322
    Abstract: A system of folding toolbars on an agricultural implement having a base toolbar, two articulating toolbars, multiple attachments to the toolbar, and a pair of hinges, with each toolbar connected to attachments. The base toolbar is located orthogonally to the direction of travel of the agricultural implement and connected to a hinge at each end, the hinges are each further connected to an articulating toolbar. Each of the toolbars is connected to a set of attachments. Each articulating toolbar rotates about the base on a pivot axis along the direction of travel of the agricultural implement and tilted relative to the ground plane, such that the center of gravity (CG) moves forward in the transport position and a normal force is applied to the articulating toolbars to resist vertical movement when in field position.

  • Patent number: 10266991
    Abstract: A vehicle combination for cleaning ballast on a track consists of a first ballast-collecting vehicle at the front with respect to a working direction, equipped with two edge-clearing chains which are mutually opposed across the width of the track and are designed to collect the ballast lying in a track bed region adjacent to the sleeper ends, and also consists of a subsequent second ballast-collecting vehicle having a continuous clearing chain that can be placed around the track to collect the ballast lying under the track, and comprising sieve systems for cleaning the ballast. In front of the first ballast-collecting vehicle there are two mutually separable sieve vehicles disposed one behind the other in a longitudinal direction of the machine and each having a sieve system. The two sieve vehicles can be loaded via a first conveyor belt line with ballast collected by the ballast-collecting vehicles.

  • Patent number: 10251330
    Abstract: The latch assembly for the wings of a folding tool bar includes catches on each wing wing and a pair of pivotal latch arms on the tool bar tongue. An actuator pivots the latch arms between an unlatched position disengaged from the wing catches to a latched position engaging the wing catches so as to retain the wings in a transport position. In the latching and unlatching method, the latch arms are pivoted simultaneously in opposite directions by an actuator to capture and release the opposing wings of the tool bar.

  • Patent number: 10046214
    Abstract: A vehicle attached rake for grooming a granular surface includes a center section and two pivotal wing sections that carry rubber trowel members having a serrated lower edge that forms a plurality of downwardly extending teeth. The tips of the teeth are located on a large diameter, upwardly facing curve to better groom upwardly curved side walls in a golf course bunker. When the rake is attached to a ZRT vehicle, the wing section on the inside of a zero radius turn is automatically lifted up off the granular surface by a flexible tether that becomes taut. Another embodiment of the rake includes a rigid plate behind a rubber trowel member with a lower portion of the trowel member folding forwardly during reverse motion of the vehicle such that the plate engages the granular surface to act as a bulldozer blade.
