Abstract

A roller flap position correction mode can be activated manually or automatically. In the roller flap position correction mode, the position of the rear roller flap is optimised so that an accumulation of material is largely avoided. The control device of the roller flap adjustment device is designed in such a way that in the roller flap correction mode, the floating position of the rear roller flap is cancelled in a first step and the rear roller flap is pivoted upwards from a first pivoted position into a second pivoted position. In a second step, the floating position is set again, so that the rear roller flap assumes a third pivoted position in which the lower edge of the rear roller flap rests on the ground. After the floating position has been reset, a checking routine is carried out, which includes at least one checking cycle.
