  • Patent number: 6305478
    Abstract: An agricultural implement, having ground engaging tools mounted on subframes that are movable through hydraulic actuators between raised transport and lowered working positions, is provided with a hydraulic circuit in which the actuators are connected in parallel with one another within a grouping of the actuators. The positioning of the ground engaging tools into a lowered working position closes the hydraulic circuit for the group of actuators. The subframes are arranged to float over ground undulations to maintain a common working depth for the ground engaging tools. The vertical movement of any one of the actuators in the common group will force a displacement of a corresponding amount of hydraulic fluid, which will then be shared by all of the remaining actuators in the corresponding group. A depth averaging control for the ground engaging tools and a mechanical headland stop apparatus are also provided for the agricultural implement.

    Abstract: An apparatus, for stabilizing a plowing implement mounted on a motor vehicle, comprising a rigid stabilizer member having first and second opposed ends. One end of the stabilizer member supports an attachment device for attaching the stabilizer member to a plowing frame secured to a motor vehicle. The attachment device allows pivoting motion of the stabilizer member relative to the plowing frame. The second end of the stabilizer member has an abutment surface for abutting against a pivotable portion of the plowing implement when the plowing implement is raised into travel position. The stabilizer member is pivotable into an inoperative position where complete freedom of movement of the plow is achieved and an operative position by a control mechanism. When the stabilizer member is in its operative position, the abutment surface abuts against a pivotable portion of the plowing implement to minimize undesired bouncing of the plowing implement while the vehicle is traveling on a roadway.
