A grain cart and foldable auger assembly having an upper auger assembly portion with a discharge portion, a lower auger assembly portion with an intake portion, and a compound angle joint that allows the upper auger assembly portion to be moved between operating and transport positions. When in an operating position, the upper auger portion and the lower auger portion are offset from each other by an operating offset angle. When in a transport position, the upper auger assembly portion is offset from the lower auger assembly portion by a transport offset angle such that the upper auger assembly portions folded across the front of the grain cart in a non-obstructive and non-protruding manner.

A header that includes at least one support and transport wheel assembly having an axle and two wheels. The wheel assembly is coupled to the main body of the header by an actuating system that includes an actuator mechanism configured to actuate a swivel movement of the axle and the wheels, the swivel movement being configured to bring the wheel assembly to or from a position wherein the axle is transversal to the longitudinal direction of the header. The wheel assembly is equipped with a drawbar that is deployable from a storage position to a deployed position, wherein the movement of the drawbar between the positions is synchronized with the swivel movement of the wheel assembly.

An agricultural vehicle including a chassis and a sectional header system carried by the chassis. The sectional header system includes a center section connected to the chassis, at least one additional section, and at least one coupling assembly that removably connects the center section to the at least one additional section. The at least one coupling assembly includes at least one actuator connected to the center section and the at least one additional section. The at least one actuator is located underneath the pivot point. The at least one additional section is configured for being coupled to the center section in harvesting of a crop material and decoupled from the center section and subsequently towable in transportation of the sectional header system.

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 machine has a symmetrical chassis hydraulically transformable between a folded transport configuration and two unfolded configurations, using articulated beams. An air seeder example has a primary beam linking a tractor to a hopper-carrying trailer, also locating the chassis. Machinery such as seed openers is held in frames pivoted from the tertiary beams. In all configurations except completely folded, lateral chains that are maintained tight with a hydraulically powered tensioning system having sideways compliance maintain the tertiary beams and frame-supported machinery in a symmetrical configuration to each side of the primary beam, when working.

A machine and method for collecting rocks in fields and then for dumping these rocks in a row for easier pickup or for storage. The machine includes one or more rock collectors for receiving rocks along with soil, smaller rocks and field debris that may accompany the rocks, and for screening out soil, field debris and smaller rocks that are small enough to pass through gaps between the grates of the rock collectors. The machine also includes rock lifter plates that assist the lifting of rocks from the field up onto the rock collectors for screening and collection. A further embodiment of the machine includes a rock collector unloader mechanism for raising the rock collectors thereby unloading the collected rocks roughly in rows. These rows may be formed off the field, or picked up more easily by hand or with a conventional row-collecting rock picker, and then removed from the field. The rock collector unloader mechanism may be attached to a trailer frame portion of the machine, the trailer frame serving to pull the rock collectors when the trailer frame is attached to a tractor or suitable pulling machine.

In one embodiment, 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.
