A soil-working device (1) for row crops, comprising: a frame (2) which extends transversely with respect to the direction of travel (F) in a working position and which has a base segment (2A) and at least one boom (2B) which is able to be folded with respect to the base segment (2A); a folding device (3) for moving the at least one foldable boom (2B) between the working position and transport position in which it is folded by at least approximately 90 degrees; and a plurality of tool carriers (6a-6i) which are arranged on the frame via in each case a remotely adjustable height-guiding device (7a-7i), wherein soil-working tools (9a) assigned to individual plant rows (8) are arranged on the tool carriers (6a-6i). To provide a soil-working device which can be moved reliably between the working position and the transport position, there is provision that the folding device (3) and at least the height-guiding devices (7d-7f) of tool carriers (6d-6f) arranged on the base segment (2A) are coupled to one another by means of a, preferably hydraulic, coupling control device in such a way that, for each movement of a boom (2B) from the working position into the transport position, the height-guiding devices (7d-7f) of tool carriers (6d-6f) arranged on the base segment (2A) move the tool carriers (6d-6f) into a position in which they are lowered relative to the frame (2).

A rod weeder wherein the rotatable rod is provided as a quick-change rod assembly comprising the rod and rod shoes for being mounted to the rod shanks resulting in the ability to quickly release and change the quick-change rod assembly from the tool frame and the remainder of the implement. Optionally, the rod weeder may comprise disk openers placed in proximity to the gauge wheels, or the support beam may be pivotally movable mounted to the connecting structure such that the same is enabled to oscillate about an axis through a centre pivot and oriented parallel to a forward moving direction of the rod weeder.

A spray boom support structure includes a first support member, a second support member, a plurality of vertical support elements disposed between the first and second support member along lengths of the first and second support members, and at least one strut. Each vertical support element includes a bottom saddle portion coupled to first support member, a top saddle portion coupled to the second support member, and an I-beam portion disposed between the top and bottom saddle portions. Further, each strut extends between adjacent vertical support elements.

An agricultural implement includes a transversely extending frame forming a first, a second, and a third frame section. A first actuator is coupled to the first frame section, a second actuator coupled to the second frame section, and a third actuator coupled to the third frame section. Sensors are coupled to each frame section to detect a height of the respective frame section relative to an underlying surface. A control unit is disposed in electrical communication with the sensors and operably controls the actuators to adjust the height of each frame section.

An example work machine generally includes a main section, a pair of inner wings, a pair of outer wings, a pair of flippers, a work assembly, a ground interface assembly, and a height control assembly. The flippers are pivotable relative to the outer wings about axes that extend in a direction transverse to the travel direction of the work machine. Each flipper includes at least one corresponding work component and at least one corresponding ground interface mechanism. The height control assembly is operable to adjust heights of the work components relative to a ground surface.

A rod weeder with a support beam pivotally movable mounted to the connecting structure such that the same is enabled to oscillate about an axis through a centre pivot and oriented parallel to a forward moving direction of the implement. Optionally, the rod weeder may comprise a down-pressure adjusting mechanism having the hydraulic cylinder mounted thereto for enabling selection of different down-pressures exerted onto the rod.

An agricultural implement includes a frame having a longitudinal axis and laterally opposed sides and motive supports mounted to and supporting the frame. The agricultural implement further includes a first wing carried by the frame and at least one second wing, in which each second wing is pivotably connected to the first wing. The agricultural implement also includes an elevator mechanism configured to raise and lower the first wing and the second wing. Each second wing is connected to the first wing by a wing pivot assembly that includes a skewed hinge pivotably connecting one of the second wings to the first wing. The wing pivot assembly allows each second wing to pivot with respect to the first wing between an operating position and a transport position, in which the skewed hinge defines a first pivot axis oriented at an acute angle with respect to the longitudinal axis.

Systems, methods and apparatus are provided for managing implement weight. In some embodiments, a position sensor is used to determine a position of the wing section and a downforce applied to the wing is modified in order to lower the wing section. In some embodiments, the position sensor indicates the position of a wing wheel assembly of the wing section. In other embodiments, the position sensor indicates the position of a center wheel assembly of a center section of the implement.

A self-propelled windrow merger includes a motor and a chassis. At the front of the merger are a first pickup and transfer assembly, a second pickup and transfer assembly and a third pickup and transfer assembly. A cab is above and behind the second pickup and transfer assembly. A folding mechanism for moves each of the pickup and transfer assemblies between a first position wherein the first, second and third pickup and transfer assemblies are laterally aligned and a second position wherein the first and third pickup and transfer assemblies are positioned rear of the cab.
