An agricultural implement has a center frame supported on center wheels and right and left interframes are pivotally attached to corresponding ends of the center frame about wing pivot axes. Right and left wing frames are pivotally attached at front inner ends thereof to front ends of corresponding interframes about front interframe pivot axes. Rear inner portions of the wing frames are movably attached to corresponding interframes. Latch mechanisms selectively lock the rear inner portions each wing frame to rear portions of the corresponding interframes. A center actuator pivots the center frame such that the frames move from an operating position extending rearward to an initial transport position extending upward where the interframes and wing frames can pivot rearward about the upright wing pivot axes. The front interframe pivot axes are oriented perpendicular to the wing pivot axes.

An agricultural tillage implement for use in a field. The agricultural tillage implement including a frame section and a plurality of wing sections. The frame section has a pull hitch extending in a travel direction. Each of the plurality of wing sections are coupled to the frame section and/or a wing section. The wing sections each have an articulated portion pivotal about an axis substantially perpendicular to the travel direction.

A header comprising multiple row elements along a width of the header. The multiple row elements are connected to a frame which is segmented into two peripheral segments and two central segments. Each peripheral segment is connected to an adjacent one of the central segments via a respective distal pivot, and the central segments are interconnected via a central pivot. The distal pivots are arranged to allow a rotation of the peripheral segments with respect to the central segments. The central pivot are arranged to allow a central rotation of the central segments with respect to each other, such that the segments are movable with respect to each other between a folded state and an operating state.

An agricultural implement includes a main frame assembly, a track assembly coupled to the main frame assembly, and a toolbar coupled to the main frame assembly. Furthermore, the agricultural implement includes a caster wheel assembly including a linkage assembly coupled to the toolbar, an actuator, and a caster wheel. The caster wheel is pivotally coupled to the linkage assembly to enable the caster wheel to caster relative to the linkage assembly while the toolbar is in a working position and in a raised position. In addition, the actuator is configured to control a vertical position of the caster wheel relative to the toolbar. The actuator has a first end and a second end, and the second end is positioned between a bottom link and a top link of the linkage assembly.

An agricultural tillage implement with a hydraulic system having a left wing hydraulic subsystem with an outer left wing hydraulic circuit supplying hydraulic pressure and flow to an actuator for actuating an actuator of an outer left wing folding implement section, and a right wing hydraulic subsystem having an outer right wing hydraulic circuit for actuating the actuator of an outer right wing implement section; the hydraulic system additionally having a hydraulic flow divider dividing hydraulic flow and pressure between the outer left wing hydraulic circuit and the outer right wing hydraulic circuit, the hydraulic flow divider being configured to coordinate the motion of the outer left wing section and the outer right wing section.

An agricultural implement having ground engaging components and inboard and outboard frame members are safely unfolded by using a radar or laser sensor to detect the presence of an obstacle in the unfolded position. A warning signal or disabling the unfolding process occurs when an obstacle is detected.

The disclosure relates to a lateral transport system for a harvester comprising a chassis, first and second ground wheels coupled to the chassis, and a lateral transport assembly operably coupled to the chassis and operable between a transport operation mode and a stowed operation mode. The lateral transport assembly comprises a tongue pivotally coupled to the chassis, a first suspension element rotatable about a first axis and a second axis, a second suspension element rotatably about the second axis, and a hydraulic actuation system operably coupled to the tongue, the first suspension element, and the second suspension element. In the transport operation mode, hydraulic fluid is allowed to flow into the hydraulic actuation system to rotate the first suspension element about the first axis, and subsequently rotate the first and second suspension elements about the second axis.

A harrow attachment for a tillage implement includes a harrow drawbar mounting at least one rank of harrowing tools. A pivot link pivotally couples the harrow rank to the drawbar so it can trip by pivoting upward toward the drawbar from a home position in which the harrow rank is farthest away from the drawbar. A downforce spring is coupled to the drawbar and in a variable length state when the harrow rank is tripped to apply a return biasing force to the harrow rank. An adjustment mechanism couples the spring to the harrow rank and/or the pivot link in one of a plurality of adjustment locations in each of which the harrow rank is in the home position and the spring is in a fixed length state in which the biasing force is removed.

A folding toolbar for an agricultural implement. A unitary flex hinge structure connects adjacent sections of the toolbar and provides a dual pivoting function. The flex hinge pivots about a first pin connected to a first section and is in pivotal connection about a second pin connected to a second section, the first and second pins defining axes that are orthogonal to each other. The unitary flex hinge further includes a lug plate that defines a mid plane along which a force may be applied. The mid plane and the axis of the first pin may be coplanar to reduce bending moments about the flex hinge relative to conventional arrangements where the axis of a hinge pin is offset relative to the plane in which the force is applied. The first pin may be mounted to a hinge mount that is mounted to lug plate for a compact design.
