A method for calibrating a selected clutch arranged within a drivetrain of an agricultural towing vehicle. The selected clutch is activatable between a closed and an open state. The method includes connecting the selected clutch in terms of drive on the drive side to a running drive motor of the agricultural towing vehicle and connecting in terms of drive on the output side to an output shaft, defining the value of a first physical variable bringing about the clutch activation, determining a second physical variable representing the rotation of the output shaft, and assigning the second physical variable representing the rotation of the output shaft to the value of the first physical variable bringing about the clutch activation, in order to generate calibration data of the selected clutch depending on the assignment.

A method for determining a torque acting at a position of a drive train of an agricultural towing vehicle, includes controlling a clutch of the drive train between a closed state and an open state, capturing a drive-side rotational speed at the clutch via a first rotational speed sensor, capturing an output-side rotational speed at the clutch via a second rotational speed sensor, controlling the clutch in the direction of the open state, determining, during controlling the clutch, a difference between the rotational speeds on the drive and output sides, comparing the difference with a predetermined difference limit value, capturing the value of a physical variable that causes the clutch control on the basis of the comparison result, and determining the torque on the basis of the captured value of the physical variable.

A method for assisting a coupling procedure at an agricultural implement interface includes determining via a control unit whether a set-down procedure associated with unhitching the implement is being executed, determining cartographically via the control unit in communication with a position detection unit a set-down location of the implement and a driving trajectory travelled by the agricultural tractor from the set-down location along a defined route, storing via the control unit the set-down location and the driving trajectory as an associated dataset in a memory unit together with type information about the implement provided by an information unit, retrieving via the control unit the associated dataset to re-hitch the implement, and guiding via the control unit the agricultural tractor back from a defined start position along the driving trajectory to the set-down location by issuing associated control commands.

A transformer with integrated cooling is disclosed. The transformer comprises a primary winding and a secondary winding, and a coolant line partly or completely embedded in at least one of the primary or secondary windings. The coolant line is supplied with coolant from a supply device. The coolant line has a plurality of exit holes that are arranged to lead in a direction of at least one of the primary or secondary winding, so as to supply it with coolant.

A current supply system of a team vehicle includes a towing vehicle operable in a cable-interconnected manner and an agricultural rear-mounted device coupled to the towing vehicle. The agricultural rear-mounted device has working equipment for performing a ground processing function. A base mast is allocated to the towing vehicle for producing a cable connection to a current supply interface of a first team vehicle that is travelling ahead, and an additional mast includes a further current supply interface allocated to the agricultural rear-mounted device for producing a further cable connection to a second team vehicle that is following. The additional mast is downstream of the working equipment of the agricultural rear-mounted device when viewed in a forward direction of travel of the team vehicle.

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.
