The device includes two opposing lateral wings forming the right and left sides of the scraping device. Each wing includes an upper section through which the wing is attached to the central support about a vertical pivot axis, and a bottom section that is pivotable with respect to the upper section about a first horizontal pivot axis. Each wing can follow the unevenness of the roadway surface and may also include parts that can pivot backwards in case of a frontal impact with an obstacle. The scraping device offers a very high degree of versatility and can clean various kinds of roadway surfaces with an unprecedented level of efficiency.

A surface grading system includes a traction unit and a scraper implement attached thereto via a three-point hitch system. A controller automatically controls an actuator of the three-point hitch system to automatically adjust a position of the scraper implement relative to the traction unit to automatically profile the ground surface to achieve a desired profile. The controller includes an Artificial Neural Network that receives a pitch angle of the traction unit and a leveling variation as input values, and outputs a hitch control signal. The Artificial Neural Network includes a first layer using a logarithmic sigmoid function as an activation function, and an output layer using a linear function as an activation function. The hitch control signal raises or lowers the three-point hitch system as the traction unit moves across the ground surface.

A dozer blade attachment control system for a work machine comprises a dozer blade attachment coupled to the attachment coupler, a hydraulic circuit, and an electronic controller. The hydraulic circuit comprises a hydraulic pump, a diverter valve operable in a first position and second position, and a pressure compensated directional control valve. The electronic controller is communicatively coupled to the hydraulic circuit. The electronic circuit may modify the hydraulic circuit to one or more of a first configuration with the diverter valve in the first position for tilt, a second configuration with the diverter valve in the second position for angling, and a third configuration with the diverter valve in the second position and the pressure compensated directional control valve creating a shuttle flow path from a higher and a lower side of the hydraulic circuit for simultaneously tilting and angling.

A blade for a work machine includes a body having a main portion including a top edge, a bottom edge, a first lateral edge and a second lateral edge. A wing portion is pivotally coupled to the body about a pivot axis. The first lateral edge includes a curved edge extending outwardly towards the wing portion, where the curved edge forms an apex between the top edge and the bottom edge. A first axis is defined through a first intersection point and a second intersection point, the first intersection point located at an intersection of the top edge and the first lateral edge and the second intersection point located at an intersection of the bottom edge and the first lateral edge. A second axis is defined through the apex and is parallel to the first axis. The pivot axis is located between the first axis and the second axis.

A land plane with a ripper, including a plane portion including at least two cutter bars and a ripper mechanism having a ripper bar assembly having ripper teeth that are shiftable between a downwardly extended orientation in which the ripper teeth are biased to extend downwardly beyond the at least two cutter bars thereby facilitating ground engaging contact of the ripper teeth and a retracted orientation in which the ripper teeth are above the at least two cutter bars. The ripper mechanism further includes a latching mechanism and a reset bar extending outwardly away from the plane portion and coupled to the latching mechanism. The reset bar is shiftable between a first position wherein the ripper teeth are secured in the retracted orientation by the latching mechanism and a second position wherein the ripper teeth are biased toward the extended position by the latching mechanism.

The present subject matter relates to devices, systems, and methods for shaping complex contours using a grading tool that is pushed or pulled along the ground. The grading tool can include a ground-engaging blade comprising a leading edge having a substantially concave profile and a trailing edge having a substantially convex profile and a coupling element connected to the blade and configured to adjust an angle at which the blade contacts a ground surface.

An attachment system for attaching an implement mounting assembly to a vehicle is disclosed. The attachment system includes a vehicle attachment component that is fastenable to a front portion of the frame of the vehicle, and a frame attachment component that is removably attachable to the vehicle attachment component on one end via a securing axis, and pivotably attachable to the implement assembly on another end about a pivoting axis. When fastened to the vehicle, the vehicle attachment component is located upward from the underside of the frame. When the frame attachment component is attached to the vehicle attachment component, the securing axis is located upward from the underside portion of the frame, and the pivoting axis is located downward therefrom.

A motor grader includes a blade between a front wheel and a rear wheel, the blade being attached to a swing circle which adjusts a blade angle. A control method performed in the motor grader includes obtaining current topography in front of the motor grader and adjusting the blade angle to an angle in accordance with the current topography by revolving the swing circle.
