An agricultural implement for cultivating an agricultural work area includes a main frame which is transferable between an operating position and a transfer position. A first subframe is connected to the main frame, and the first subframe is transferable between an operating position and a transfer position. A main frame hydraulic cylinder and a first subframe hydraulic cylinder move the main frame and the first subframe between their corresponding positions. In order to provide correct and repeatable positioning of the first subframe hydraulic cylinder, a volume of a first chamber of the main frame hydraulic cylinder is substantially equal to a volume of the first chamber of the first subframe hydraulic cylinder when the first subframe is in its operating position.

The present invention relates to an agricultural machine intended to be hitched to a tractor and comprising two side units and a frame, which extends in a longitudinal direction, each side unit comprising an arm mounted so as to pivot relative to the frame around a respective folding axis oriented substantially parallel to the longitudinal direction, each side unit comprising a tool unit connected to the frame by means of the respective arm and being able to occupy a work position in which it rests on the ground, each side unit also comprising a connection means, which is configured to allow the respective tool unit in work position to move relative to the respective arm and which comprises at least one lightening actuator enabling an upward force to be exerted on each tool unit in work position. It is noteworthy in that the machine comprises a tie-rod connected to each of the arms through a respective upper joint of an axis parallel to the respective folding axis.

A tillage implement having a frame member extending in a fore-aft direction of the implement, the frame member pivotally connected in a foldable configuration, the frame member comprising a main frame section; a first wing section and a second wing section, each being pivotally connected at opposing lateral sides of the main frame section in the fore-aft direction; and a middle breaker including a first disc coupled to the main frame section, the first disc laterally offset from a centerline of the middle breaker extending in the fore-aft direction, the first disc having a concave side facing towards the centerline, and a second disc coupled to the main frame section, laterally offset from the centerline of the middle breaker, the second disc having a concave side facing towards the centerline.

A liquid manure spreader includes a spreader vehicle, a transversely extending injector boom having at least one outer boom section pivotable between a transversely-oriented position and a vertically-oriented position, at least one first actuatable linkage assembly for translating the boom vertically between a lowered working position and a raised position, and at least one second actuatable linkage assembly for arcuately pivoting the boom about an axis parallel to the transverse axis between a highest vertical height position and a lower transport position when the boom is in the raised position and the at least one outer boom section is in the vertically-oriented position.

A hinge for an agricultural machine having a center section having a first aperture, a wheel supporting the center section, a wing section connected to the center section and having a second aperture, and a hinge positioned between the center section and the wing section to permit the wing section to pivot about the center section. The hinge includes a pin which extends through the first and second apertures to connect the wing section to the center section. A first fastener engages the center section or the wing section and is adjacent to the first end of the pin to thereby retain the pin in the first and second apertures. A second fastener engages the center section or the wing section and is adjacent to the second end of the pin to thereby retain the pin in the first and second apertures.

A harvesting header for a combine harvester comprises a central header section and two lateral header sections hinged to and arranged to rotate relative to the central section for assuming a working configuration, in which the three header sections are mutually horizontally aligned, and a transport configuration, in which the lateral header sections overlap the central section. The header sections are provided with a support frame and a cutting bar associated with the support frame by a hydraulic suspension and comprising a blade having substantially trapezoid-shaped knives capable of to-and-fro movement by a motor-driven control member. The header sections also include a pick-up reel supported on the support frame by means of swivel arms, a transport belt conveyor arranged downstream of the cutting bar and configured to feed the material cut by the cutting bar downstream of the harvesting header toward a rear part of the harvesting header.

A method for controlling the actuation of wing sections of an agricultural implement may include regulating a supply of hydraulic fluid to a wing actuator coupled to a wing section to pivot the wing section relative to a center frame section of the implement from a transport position towards a work position. The method may also include monitoring a wheel load associated with at least one wheel of the wing section as the wing section is being moved towards the work position and detecting when the wheel(s) of the wing section contacts the ground based at least in part on the monitored wheel load. In addition, the method may include adjusting one or more flow parameters of the supply of hydraulic fluid to the wing actuator to reduce an actuation rate at which the wing section is being pivoted after detecting that wheel(s) has contacted the ground.

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.

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.
