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 row unit for a work vehicle includes a row unit frame with a closer frame. The closer frame defines a longitudinal axis and a transverse axis. The closer frame is supported for rotational movement about a substantially vertical steering axis to vary a turning angle between the longitudinal axis the vehicle longitudinal axis. The row unit includes a closer implement assembly with first and second closer implements and a walking beam construction. The first and second closer implements are attached to opposite areas of the walking beam construction. The walking beam construction is rotationally attached to the closer frame to support rotation of the closer implement assembly about the transverse axis. The first and second closer implements are configured to move ground material into a ground opening from opposites sides as the work vehicle moves across the field.

A modular autonomous agricultural vehicle includes a drive module having a frame, a ground-engaging element rotatably coupled to the frame, a power source, and a drive motor receiving power from the power source and coupled to the ground-engaging element for rotating the ground engaging element. At least one toolbar module is detachably coupled to the frame for coupling the drive module to an agricultural implement or another modular toolbar segment. The modular toolbar preferably includes multiple toolbar modules coupled to each other in series to form the modular toolbar.

An agricultural toolbar has a center section and opposite wings which are horizontally foldable between transport and field positions. The toolbar has a hydraulic system which is very adaptable to many different hydraulically controlled features and options, without sacrificing the primary purpose of the system, which is accurately controlling the operating height of the toolbar, to achieve optimal planting depth of modern precision seed and fertilizer application systems.

A fork assembly including a retention mechanism to retain an agricultural machine having a remotely controllable moveable element that is moveable between a number of positions. The retention mechanism includes a control element positioned so that, when engaged with the agricultural machine, the movement of the control element due to movement associated with the remotely controllable moveable element is arranged to cause actuation and deactuation of the retention mechanism.

In one aspect, a method is disclosed for transporting an autonomous agricultural vehicle and an operator-driven agricultural vehicle from a first agricultural work site to a second agricultural work site. Each of the vehicles may have respective front ends and rear ends, and each of the respective rear ends may include a respective hitch. The method may include arranging the autonomous agricultural vehicle and the operator-driven agricultural vehicle such that the rear end of the autonomous agricultural vehicle faces the rear end of the operator-driven agricultural vehicle. The method may include coupling the hitch of the autonomous agricultural vehicle with the hitch of the operator-driven agricultural vehicle. The method may include towing the autonomous agricultural vehicle behind the operator-driven agricultural vehicle with the rear end of the autonomous agricultural vehicle facing a forward travel direction of the operator-driven agricultural vehicle.

In one aspect, an auxiliary tool assembly for an agricultural implement may be configured to support a finishing tool(s) at a location at or adjacent to the aft end of the implement. The auxiliary tool assembly may include a support arm extending lengthwise between a proximal end and a distal end, with the proximal end of the support arm being pivotally coupled to a portion of the implement at or adjacent to its aft end so that the tool assembly is pivotable relative to the implement between a work position and a transport position. In addition, the finishing tool(s) may be configured to be coupled to or otherwise supported relative to the ground by the support arm at a location between its proximal and distal ends. Moreover, the auxiliary tool assembly may include one or more surface-engaging wheels coupled to the distal end of the support arm.

A cutting unit for an agricultural working machine and a method for adjusting the cutting unit are disclosed. The cutting unit comprises a support body, a cutting device on the support body, a front suspension arranged on the support body on a first half of the cutting unit and has at least one wheel that rotates about a front axle and a rear suspension on the support body on a second half of the cutting unit and has at least two wheels that rotate about a rear axle, the front suspension and the rear suspension being rotatable about a respective rotary axis relative to the support body so that the front and rear suspensions can each be transferred between a transport position and a working position. The front suspension and the rear suspension, when in their respective working position, are moved relative to the support body between a high position and a low position.
