摘要： A tool carrier has a carrier frame and ground tools, and a front end of the carrier frame is connected to a wheel supported tool bar frame. A crank arm is pivotally attached to the tool bar frame about a crank axis oriented horizontally and perpendicular to an operating direction. A front end of the carrier frame is pivotally attached to the crank arm about a carrier axis parallel to the crank axis, and a hydraulic cylinder attached between the crank arm and the tool bar moves the tool carrier from an upward transport orientation to a rearward extending horizontal operating orientation, and maintains the tool carrier horizontal while moving it from a headland position above the ground to a working position where the tools penetrate the ground. When the tool carrier assembly is in the working position, the hydraulic cylinder exerts a downward bias force on the tool carrier.

摘要： An agricultural implement system includes a down force cylinder configured to apply a downward force to a row unit, and a depth control cylinder configured to vary a penetration depth of a ground engaging tool of the row unit. The agricultural implement system also includes a valve assembly in fluid communication with the down force cylinder and the depth control cylinder. The valve assembly is configured to automatically adjust the downward force by varying fluid pressure within the down force cylinder based on fluid pressure within the depth control cylinder.

摘要： An agricultural row unit includes an attachment frame adapted to be rigidly connected to a towing frame, and a linkage assembly pivotably coupled to the attachment frame to permit vertical pivoting movement of the linkage assembly relative to the attachment frame. The row unit further includes a hydraulic actuator coupled to the linkage assembly for urging the linkage assembly downwardly toward the soil, and a hose connection manifold mounted adjacent to the hydraulic actuator for circulating hydraulic fluid between a hydraulic source and the hydraulic actuator. The hose connection manifold has a modular port for accepting, one at a time, a removable control valve and a port plug.

摘要： An agricultural implement is provided having a tongue, a central toolbar extending from the tongue, and first and second wings extending generally outwardly from the central toolbar. The implement may include a central hopper system to provide the material to individual row units along the central toolbar and wings, or may include individual hoppers located at each of the row units along the toolbars. A weight distribution system is used with the implement to update and adjust the amount of down force applied at the outer toolbars or wings, and the individual row units. The distribution system includes an intelligent control connected to sensors and cylinders. Therefore, the intelligent control receives information from the sensors and adjusts the cylinders accordingly to provide the appropriate amount of down force and to adjust the down force on a real time basis, and can be a closed loop or open loop system.

摘要： The hitch on a vehicle is moved by a hydraulic actuator. A method for controlling the hydraulic actuator defines a draft force setpoint in response to separately averaging two forces acting on lateral sides of the hitch, while operating in a configuration mode. During regular operation, a draft load is calculated from sensing those two forces and deriving a draft force error from difference between the draft load and the draft force setpoint. The draft force error is used to control fluid flow to and from the hydraulic actuator. One aspect of the control method derates the draft force error as the hitch moves beyond a predefined threshold position.
