  • Patent number: 9587371
    Abstract: The reversible bucket attachment system for a skid steer includes a mounting plate that is configured to attach to a skid steer or any vehicle. The mounting plate includes an armature that extends rearwardly, and includes a pivoting point on a distal end. The pivoting point enables a bucket to attach thereto. Moreover, the bucket is able to pivot with respect to the armature via the pivoting point. The bucket is able to rotate from a generally parallel orientation with respect to the armature to an obtuse orientation. The bucket is further defined with an inner surface and an outer surface. The mounting plate is configured to attach to the skid steer or vehicle in one of two positions.

  • Patent number: 8689898
    Abstract: A multi-use attachment device that is easily attached to and removed from an all-terrain vehicle (ATV) or a utility-terrain vehicle (UTV) comprises a lift frame including an inner lift frame, an outer lift frame, a first pivotal axis and a second pivotal axis, and is configured to pivot about the first pivotal axis with a first electrical device, and has a second electrical device mounted on the lift frame to pivot the outer lift frame with respect to the inner lift frame. One end of the multi-use attachment is attached to the ATV/UTV, and the other end is attached to an implement such as a loader bucket, a pallet fork, or a plow blade. Some embodiments of the multi-use attachment use tension devices both for pivoting the lift frame about the first pivotal axis and for pivoting the outer lift frame with respect to the inner lift frame about the second pivotal axis.

  • Patent number: 8631595
    Abstract: A swivel adapter mount can be mounted on the end of a boom of excavating equipment, such as a crawler excavator or on a backhoe. Rotation of the swivel adapter mount will impart rotation to an implement, such as bucket, mounted on the boom. This rotation is not possible with a conventional wrist joint on the boom of an excavator or backhoe. With the bucket swiveled using this swivel adapter mount, a slope may be defined on the sides of a ditch, by only using the backhoe or excavator. The implement can be swiveled or tilted about transverse axes as will as being manipulated by a conventional wrist joint. Gear bearings having gear teeth of divergent thickness are employed on the swivel adapter.

    Abstract: An apparatus for swiveling an implement, such as a bucket, relative to a device, such as an excavator boom, includes a rotary union and a bearing disc mounted in a housing. The bearing disc rotates relative to the housing so that the implement can be rotated relative to the device. A gear or geared bearing assembly is located between the bearing disc and top and bottom housing portions for bearing loads transverse to the axis about which the implement is rotated relative to the device. The rotary union has fluid passages extending from the top to the bottom of a central shaft, which is affixed to the bearing disc, and the shaft and disc can comprise a one piece combination rotary union and bearing disc.

  • Patent number: 8109531
    Abstract: A system for push-steering an implement includes a pair of links, each link connecting the implement to a front portion of a motorized vehicle. Each link of the pair of connected links between the motorized vehicle and the implement is non parallel to each other. In response to the motorized vehicle traveling at a first predetermined steering angle, a traction element developed between at least two wheels of the implement and the driving surface rotatably urges one link toward a predetermined offset angle in a rotational direction opposite of the first predetermined steering angle. The pair of links simultaneously rotatably urges the implement to be steered toward a second predetermined steering angle in the same rotational direction as the first predetermined steering angle. The predetermined offset angle and second predetermined steering angle define a substantially stable position in response to the first predetermined steering angle.
