The agricultural implement includes a front linkage assembly extending between the main frame and the tool frame. The front linkage assembly is coupled to the tool frame vertically above the front row. The agricultural implement also includes a central linkage assembly extending between the main frame and the tool frame. The central linkage assembly is coupled to a central portion of the tool frame between the front row and the rear row. The front row is configured to pivot upwardly and downwardly relative to the rear row.

A harrow attachment for a tillage implement has a harrow drawbar, configured to mount to a frame member of the tillage implement, and at least one harrow rank having a rank bar supporting a plurality of harrowing tools oriented to extend away from the rank bar. An anti-tangle bracket assembly has a first pivot link coupled to the harrow drawbar and a second pivot link pivotally coupled to the at least one harrow rank. The first and second pivot links pivot about pivot axes with respect to one another within a pivotal range of movement of the at least one harrow rank from a first, extended position to a second, tripped position.

A three-point hitch drawn platform for an agricultural implement for conditioning soil, crop residue and the like, particularly suitable for use with a disc harrow with at least front and rear disc gangs. A main frame having first and second ends is formed to support said front and rear disc gangs, respectively, so as to facilitate real-time, limited repositioning of the disc gangs relative to first and second stabilizer bars forming part of a subframe which further includes a hitch frame with three-point hitch. The main frame is pivotally connected to the hitch frame at one end, so that other end of said main frame can pivot in response to terrain variations within a predefined distance via first and second stops, each free end of the stabilizer bars engaging the main frame via adjustable helical spring or the like, thereby providing adjustable downward bias transferred to the front and rear disc gangs to accommodate variations terrain during operation, effectively facilitating more consistent tension on the front and rear disc gangs, while providing more enhanced, stable, and consistent terrain penetration during the harrowing process. The present invention further limits or eliminates the issue of alternating right to left thrusting of the discs associated with conventional harrowing implements when three-point hitches are utilized, as well as the associated erratic steering movement on the tractors front steering during same.

An implement support assembly includes an implement interface having an interface support frame pivotably coupled to a vehicle frame, the interface support frame including an interface support arm and a float feature, and a hydraulic cylinder configured to move the interface support frame relative to the vehicle frame, the float feature being positioned between the interface support frame and the hydraulic cylinder. The float feature is configured to permit the implement to move independently from the hydraulic cylinder in response to ground undulations. The float feature includes a link having a first end coupled to the interface support arm, a second end coupled to the hydraulic cylinder, and a protrusion positioned between the first and second ends, the interface support arm includes an interface slot, and the protrusion is slidably received within the interface slot to provide lost motion between the link and the interface support arm.

An agricultural implement includes at least one row unit having a plurality of support members, each of which is pivotably coupled to an attachment frame or another of the support members to permit vertical pivoting vertical movement of the support members, and a plurality of soil-engaging tools, each of which is coupled to at least one of the support members. A plurality of hydraulic cylinders are coupled to the support members for urging the support members downwardly toward the soil. A plurality of controllable pressure control valves are coupled to the hydraulic cylinders for controlling the pressure of hydraulic fluid supplied to the cylinders. A plurality of sensors produce electrical signals corresponding to predetermined conditions, and a controller is coupled to the sensor and the controllable pressure control valves. The controller receives the electrical signals from the sensors and produces control signals for controlling the pressure control valves.

A harvesting system includes a header pivotally attached to a combine. The header includes a center section to which a left wing and right wing are pivotally attached. A suspension system of the harvesting system includes first and second engageable states that enable dynamic wing behavior and reduce structural load. The first state corresponds to a harvesting configuration of the header in which the wings are allowed to pivot to allow the header to follow changes in terrain. The second state corresponds to a configuration in which the header is elevated relative to the ground. In the second state, the ability of the wings to pivot is minimized as compared to the first state, which allows the header to be maintained in a substantially flat configuration while minimizing the amount of dynamic load imparted by the header on the combine during non-harvesting transport of the header.
