Agricultural vehicle-trailer combination

A vehicle fleet, comprising:

• a plurality of individual vehicle-trailer combinations, wherein each of the plurality of individual vehicle-trailer combinations comprises:
• a traction module including a drive element for engaging in a ground;
• a working appliance coupled to the traction module by a coupling apparatus;
• a folding axle supporting the working appliance relative to the ground at least during a transport mode;
• a slewing mechanism of the coupling apparatus for providing a degree of freedom of rotation between the traction module and the working appliance along a longitudinal axis of the working appliance;
• and
• a pivot joint for providing a degree of freedom of pivoting between the traction module and the working appliance along a vertical axis of the traction module;
• wherein, 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.
