A portable frame is configured to be transported by the forks of a fork lift truck and has hydraulic lines releasably connectable to the auxiliary hydraulic fluid pressure system of the fork lift truck. A valve and a set of hydraulic lines are mounted on the portable frame for releasable connection to the hydraulic fluid lines of a tillage machine so that an inexpensive fork lift truck may be utilized to test operation of hydraulically actuated tillage components.

A mowing device (10) has a central frame mounted on wheels (16a, 16b) carrying at least two mowing units (20a, 20b) which are each connected to the central frame (12) via a connection unit (24a, 24b), wherein a connection unit (24a, 24b) includes a main pivot arm (28a, 28b) and an outer pivot arm (26a, 26b), the outer pivot arm (26a, 26b) connected to the main pivot arm (28a, 28b) in such a manner that it is pivotable about an outer arm joint (34a, 34b) relative to the main pivot arm (28a, 28b), the connection unit (24a, 24b) further including a mowing unit joint (32a, 32b) for connecting the mowing unit (20a, 20b) to the outer pivot arm (26a, 26b), the mowing unit joint (32a, 32b) arranged at the end of the outer pivot arm (26a, 26b) that is remote from the outer arm joint (34a, 34b).

The invention relates to an adjustable hoeing device (10) for removing weeds situated on a ground surface, the hoeing device (10) having a supporting frame (50), on which there is arranged at least one hoeing unit (100), which hoeing unit comprises the following:at least one main bar (200) and at least two transverse bars (250) arranged parallel to one another, which transverse bars (250) are each mounted rotatably on the at least one main bar (200);at least two connection bars (300), which run parallel to the at least one main bar (200) and which mechanically connect the at least two transverse bars (250) to one another;at least two blades (500), wherein the blades (500) are arranged on the at least two transverse bars (250) at a normal distance from the main bar (200); andat least one actuation device (400), which acts on at least two transverse bars (250) or a transverse bar (250) and the main bar (200) in order to rotate same by means of a linearly displaceable actuation arm.

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 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.

An agricultural mowing machine comprises a carrying arm. A lateral displacement structure is connected to the carrying arm and can be displaced relative to the carrying arm in a lateral direction between an inner position and an outer position. A mowing unit is connected to the lateral displacement structure. The mowing unit can be moved between an approximately horizontal working position, a raised headland position, and a transport position. A first hydraulic cylinder and a second hydraulic cylinder are connected to each other in such a manner that hydraulic fluid discharged from said first or second hydraulic cylinder is supplied under pressure to the other of the first or second hydraulic cylinder for pivoting the carrying arm so as to move the mowing unit from the transport position towards the headland position displacing the lateral displacement structure outwards relative to the carrying arm simultaneously.

A harvesting platform is connected to a combine for movement with the combine over the ground surface. The harvesting platform includes a cutter bar that cuts a crop being harvested, and a reel that presses the crop against the cutter bar during harvesting. The cutter bar moves between a cutter bar harvesting position and a cutter bar transport position, and the reel moves between a reel harvesting position and a reel transport position. A controller receives a first signal from a user via a user interface, sends a second signal to the cutter bar to move the cutter bar between the cutter bar harvesting position and the cutter bar transport position in response to the first signal, and send a third signal to the reel to move the reel between the reel harvesting position and the reel transport position in response to the first signal.

A control system for an agricultural utility vehicle includes a distributor linkage for applying fertilizer, plant protection agents, or seed, the distributor linkage having a center part and two lateral extension arms. The center part is arranged so that it can be moved along a vertical axis to adjust the height of the distributor linkage. At least three sensors for determining the distance between the center part and a respective extension arm to the ground are assigned to the distributor linkage, and the system includes a data processing unit such that signals from the sensors are processed as actual values to generate an actuating signal for a hydraulic device is generated for adaptation to a target distance.

An agricultural toolbar employs at least two wing assemblies for following the contour of the land in a working position and foldable to a transport position for transit on public roads. The principal use in working position benefits from having a wide range of movement to accommodate variations in land contours and soil types. The principal use in transport mode benefits from having a compact configuration to better meet road regulations. End-uses that condition cultivatable land at multiple locations will benefit from the toolbar.
