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).

Agricultural device for soil processing with two sets of working rollers comprising a supporting frame, which comprises a central part, a left wing and a right wing, wherein the left and right wing are rotatably attached to the central part, at least two rows of working units attached to the supporting frame, wherein the working units are arranged in regular distances in every row, a left set of rollers attached to the left wing and a right set of rollers attached to the right wing, wherein the sets of rollers are divided into front rollers and rear rollers and provided with attachments and discs, wherein the discs on the sets are located between these attachments. The number of discs of rear rollers differs exactly by one disc from the number of discs of front rollers, wherein the distances between individual discs are the same along the whole width of the agricultural device, and wherein the discs of front rollers are located in the same plane as the working units.

A system for hydraulically leveling a multi-wing agricultural implement having a pressure regulating valve and a folding valve fluidly coupled in parallel between a supply line, configured to provide a supply pressure of hydraulic fluid, and an actuator, configured to move an outer-wing section of the implement between a transport position and a fully-extended position. Specifically, when fluid is supplied to the actuator via the pressure regulating valve, only a portion of the supply pressure is allowed through the pressure regulating valve to the actuator such that the outer-wing section may pivot towards a position where the outer-wing section is substantially level with the inner-wing section. When hydraulic fluid is supplied to the actuator via the folding valve, the outer-wing section is actuated towards the transport position. When hydraulic fluid is supplied to the actuator via the leveling valve, the outer-wing section is leveled relative to the inner-wing section.

A tillage implement for variable tillage has a linkage mechanism disposed longitudinally between two gangs of annular harrow tools, the gangs each having a toolbar that is rotationally mounted on a frame of the implement. The linkage mechanism has a plurality of pivotally connected linkage arms, the toolbars each pivotally connected to at least one of the linkage arms. Operation of the linkage mechanism simultaneously rotates one toolbar about a first vertical rotation axis and the other toolbar about a second vertical rotation axis in an opposite rotational direction as the first toolbar. The implement has at least one wheel mounted on the frame longitudinally forward of both of the gangs or longitudinally rearward of both of the gangs. The tillage implement provides variable tillage while having a shorter frame to facilitate folding wing sections of the frame in a more compact manner for transportation while remaining assembled.

An agricultural implement including a frame with a main frame section and at least one wing frame section such that the agricultural implement is configured for transitioning in between a work position and a transport position, at least one conveyance line, and at least one coupling device. The at least one coupling device includes a first coupling member attached to the first line portion and a second coupling member movably connected to the first coupling member and attached to the second line portion such that the at least one coupling device couples the first line portion and the second line portion of the at least one conveyance line in the work position and uncouples the first line portion and the second line portion of the at least one conveyance line in the transport position.

An agricultural device with two work units, the device being able to occupy a work configuration and a transport configuration and comprising a support arm pivotally mounted on a chassis around a lift axis substantially parallel to the direction of advance and around which the device is pivoted to reach the various configurations mentioned above, each unit being pivotally mounted relative to the support arm around a connecting axis, each unit comprising a respective guided end and a respective free end further away from the corresponding connecting axis than its guided end. The agricultural device includes a central actuator configured to apply on each of the units a biasing force opposed to a downward pivoting movement by its free end around the corresponding connecting axis, at least in the work configuration.

An agricultural implement includes a main frame attachable to a towing vehicle, a wheel support supporting the main frame and having main wheels, and a lifting unit configured to bring the agricultural implement into one of a transport position, a working position, or a headland position.
