A method for reducing an overall transport profile of a multi-section tillage implement. The tillage implement may include a frame including a center frame section and at least one wing frame section. The tillage implement may include a plurality of ground-engaging tools pivotally mounted to the frame. The method may include pivoting each of the plurality of ground-engaging tools away from the ground surface from a ground-engaging position to a retracted position. The frame may be disposed at an initial height relative to the ground surface before pivoting. After pivoting, the frame may be lowered to a transport height relative to the ground surface. At least one wing frame section may be folded relative to the center frame section from an operating position to a transport position to reduce a width of the tillage implement in the widthwise direction.

CONTROL SYSTEM, AGRICULTURAL UTILITY VEHICLE AND METHOD FOR CONTROLLING AN AGRICULTURAL UTILITY VEHICLE
20210127657 · 2021-05-06 ·

The invention refers to a control system for an agricultural utility vehicle (1) comprising a distributor linkage (4) for applying material, such as fertiliser, plant protection agents or seed, said distributor linkage extending transversely to the direction of travel and having a centre part (2) and two lateral extension arms (3), which are connected to the centre part (2) by joints and having a plurality of linkage sections which can be folded in towards one another in the transport position and folded out in the working position. The centre part (2) is arranged so that it can be moved along a vertical axis to adjust the height of the distributor linkage. At least one hydraulic device is associated with each extension arm (3), whereby the respective extension arm (3) is pivotable about a horizontal axis. Furthermore, at least three sensors (5) for determining the distance between the centre part (2) and the respective extension arm (3) to the ground are assigned to the distributor linkage (4), and the system comprises a data processing unit which is configured in such a way that the signals from the sensors (5) are processed as actual values and on the basis of which an actuating signal for the hydraulic device is generated for adaptation to a target distance. Thus, the target distance for pivoting the extension arms (3) is formed using the current actual value of the centre part (2). The invention also refers to an agricultural utility vehicle (1) and a method for controlling an agricultural utility vehicle (1).

Agricultural machine frame

A hydraulically-foldable agricultural machine frame includes a hydraulic cylinder assembly that connects and pivots two lateral parts of the hydraulically-foldable agricultural machine frame relative to one another, wherein unrestricted pivoting or folding of the lateral parts is prevented by movement of the hydraulic cylinder assembly only being guided or delimited laterally.

IMPLEMENT HAVING WEIGHT TRANSFER SYSTEM AND METHOD OF OPERATING THE SAME
20210127549 · 2021-05-06 ·

An implement includes a frame having a main section and a wing section pivotally coupled to the main section. A row unit is mounted to the frame wing section to dispense a product to the ground surface. A weight transfer system transfers weight from the frame main section to the frame wing section to reduce the load carried by the main wheel assembly. A row unit downforce system applies a force on the row unit relative to the frame wing section. A pressure transducer measures the force applied by the row unit downforce system and generates a signal indicative of the applied force. A control system operates the weight transfer system in response to the signal from the pressure transducer to assist the row unit downforce system. The control system actuates the weight transfer system to apply an additional force on the frame wing section in response to the signal.
