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.

An agricultural machine includes two side units and a chassis that extends in a longitudinal direction and is equipped with two wheels, each side unit being fitted to pivot in relation to the chassis around a folding axis parallel to a median plane of the chassis. Each side unit includes a tool unit connected to the chassis by an arm and being able to occupy a work position in which the length of the tool unit extends transversely to the longitudinal direction. Each side unit is also able to occupy a transport position in which the length and width of the tool unit are parallel to the median plane. The machine includes a tilter articulated with the chassis around one tilting axis oriented transversely to the longitudinal direction, and in the transport position of the side units, each tool unit is closer to the median plane than the respective arm.

A mini-hopper for an agricultural row unit that has a fill tube supplying material to a hopper. A backflow preventer is disposed in the fill tube or in a line to the inlet to prevent flow of material from the mini-hopper through the fill tube when the mini-hopper is in a transport position.

A tillage implement has a frame with a center section and first and second outer wing sections hingedly attached to respective outer ends of the center section. Controlling a pressure in a secondary side of a hydraulic circuit enables adjustment of the downward pressure precharge provided by hydraulic cylinders based on a desired stiffness of the implement. Flow from a hydraulic supply through a pressure-reducing valve puts the downward pressure precharge on gauge wheels. Once this desired downward pressure precharge has been achieved, flow from the hydraulic supply is shut off and a check valve holds the pressure such that the hydraulic cylinders hold the gauge wheels in the desired position.

An agricultural machine hitched to a tractor and includes two side units and a frame, which extends in a longitudinal direction, each side unit including 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 including a tool unit connected to the frame through the respective arm and being able to occupy a work position in which it rests on the ground, each side unit including a connection allowing the respective tool unit in work position to move relative to the respective arm, the connection includes a lightening actuator enabling to exert an upward force on each tool unit in work position. The machine includes a tie-rod connected to each of the arms through a respective upper joint of an axis parallel to the respective folding axis.

An agricultural vehicle-trailer combination includes a traction module including a drive element for engaging in a ground, a working appliance coupled to the traction module by a coupling apparatus, and a folding axle supporting the working appliance relative to the ground at least during a transport mode. A slewing mechanism of the coupling apparatus provides a degree of freedom of rotation between the traction module and the working appliance along a longitudinal axis of the working appliance. A pivot joint provides a degree of freedom of pivoting between the traction module and the working appliance along a vertical axis of the traction module. The pivot joint is adjustable relative to its pivot angle by a steering actuator for influencing the direction of travel of the vehicle-trailer combination.
