Abstract

A combination of a tractor and an implement is pulled by the tractor. A draw bar is coupled to the tractor so as to be pivotable about a vertical axis. The implement is supported on the ground by wheels and comprises a cultivating element for cultivating a field. A control device is usable to activate a first actuator with which the a position of the draw bar is changeable in relation to the implement, where the control device can be operated in order to activate the first actuator in such a manner that the latter adjusts the draw bar with the effect of moving the implement toward the outside of a curve.
