A towed implement, such as a cultivator is configured between an unfolded operational position and a folded transport position in which wing sections are pivoted about a vertical axis into a forward direction where they are alongside a telescoping tool bar. Sensors on the cultivator send signals initiating the folding/unfolding sequence to send commands through the implement controller to a tractor controller having a ISOBUS class 3 configuration. The tractor is commanded to forward and rearward movement in synchronism with the folding/unfolding process to steer wing supporting wheel assemblies toward the correct position for the intended transport direction

An agricultural implement including a central chassis member having a support structure with support arms connected to the support structure for movement between a working position and a transport position, the support arms having operating elements defining a working width between the operating elements and the main chassis member. The support arms are adjustable in the working position between a length corresponding to minimum working width and a length greater than the minimum working width. In the transport position a distance between the operating elements and the main chassis member is less than the minimum working width. A first stop defines the position of the minimum working width and a second stop arranged vertically with respect to the first stop retains the support arm in the transport position when the distance between the operating elements and the main chassis member is less than the minimum working width.

An implement comprising a center section and a pair of wing sections, each of the sections comprising a pair of parallel frame members pivotably coupled to each other, wherein one of the frame members comprises a toolbar; and a plurality of hydraulic cylinders enabling rotational movement between the parallel frame members, wherein the hydraulic cylinders of the wing sections comprise double-rod cylinders and the hydraulic cylinders of the center section comprises single-rod cylinders.

A system for remotely controlling hydraulic component of an agricultural implement towed by a work vehicle may include a vehicle-based valve assembly that selectively supplies hydraulic fluid to one or more supply lines of the implement. Specifically, a first supply line may be fluidly coupled to an implement-based valve assembly that regulates the supply of hydraulic fluid to a hydraulic actuator through a first actuator line. A second supply line may be fluidly coupled to the first actuator line downstream of the implement-based valve assembly such that when a user provides a control input at a remote interface, the vehicle-based valve assembly may instead regulate the supply of hydraulic fluid to the actuator. The supply of the hydraulic fluid through the supply lines may additionally be controlled by first and second override valves fluidly coupled to the first and second supply lines, respectively.

A hinge assembly for an agricultural implement having inner and outer wing frame sections has an inner pivot bracket pivotally coupled to the inner wing frame section at a fold pivot location, and an outer pivot bracket pivotally coupled to the outer wing frame section at a flex pivot location and coupled to the inner pivot bracket. An inner pivot link pivotally couples to the inner pivot bracket and the outer pivot bracket, and an outer pivot link pivotally couples to the outer pivot bracket and the outer wing frame section. The inner and outer pivot brackets pivot relative to each other at the fold pivot location between a working state and a folded state, and the flex pivot location moves relative to the fold pivot location during the relative pivoting. When in the working state, the fold pivot location is higher than a top side of the inner wing frame section and the flex pivot location is lower than a bottom side of the inner wing frame section.

A hinge assembly is provided for pivotally connecting a first frame section and a second frame section. The hinge assembly includes at least one pivot plate pivotally connected to the first mounting structure of the first frame section with a first pin and pivotally connected to the first mounting structure of the second frame section with a second pin. The hinge assembly further includes a linkage bar with a first end pivotally connected to the second mounting structure of the first frame section with a third pin and a second end pivotally connected to the second mounting structure of the second frame section with a fourth pin. The pivot plate and the linkage rod are configured such that the second frame section pivots about the fourth pin during a working state and about the third pin during a transition between the working state and a folding state.

An agricultural implement configured to shift weight between a center toolbar and left and right wing sections. Each wing section includes inner and outer sections pivotally coupled about a horizontal axis. Left and right wing flex actuators pivot the outer wing sections with respect to the inner wing sections about the respective left and right horizontal axes. Each of the inner wing sections is pivotally coupled to the center toolbar about respective left and right vertical axis. The center toolbar section is supported by a center wheel assembly and distal ends of the left and right outer wing sections are supported by respective left and right wing wheel assemblies. A monitor is in signal communication with load sensors on each of the wheel assemblies and a fluid control system to actuate the wing flex actuators so the measured center wheel load approaches a center wheel target load.

In one aspect, a method for reducing an overall transport profile of a multi-section tillage implement. The tillage implement includes a frame including a center frame section and at least one wing frame section. The tillage implement includes a plurality of ground-engaging tools pivotally mounted to the frame. The method includes pivoting each of the plurality of ground-engaging tools away from the ground surface from a ground-engaging position to a retracted position. The frame is disposed at an initial height relative to the ground surface before pivoting. After pivoting, the frame is lowered to a transport height relative to the ground surface. At least one wing frame section is folded relative to the center frame section from an operating position to a transport position to reduce a width of the tillage implement in the widthwise direction.

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.
