METHOD FOR CONTROLLING AN AGRICULTURAL MACHINE WHEN WINDROWING A CROP ON AN AGRICULTURAL AREA AND AGRICULTURAL MACHINE

摘要

The invention relates to a method for controlling an agricultural machine during the swathing of a crop on an agricultural area, comprising: providing an agricultural machine with a swather (1), in which a combination of computation devices (4a, 4b, 5a 5b) arranged to swirl a crop on an agricultural land; Moving the agricultural machine with the swather (1) on the agricultural land, thereby swathing the crop; repeatedly determining machine position data for the agricultural machine by means of a position determining system while the agricultural machine is being moved on the agricultural area, the machine position data indicating a current position of the agricultural machine on the agricultural area; Providing electronic location information, wherein the electronic location information includes position information indicative of a distribution of the crop to be swarmed along a non-straight line in a partial area of the agricultural area; and controlling the computation devices (4a, 4b, 5a, 5b) by means of control signals generated by a control device, if it is determined in a data processing of the machine position data and the position information by means of the control device that the crop is being swathed in the subarea of the agricultural area in that a work position of one or more computation devices (4a, 4b, 5a, 5b) is adjusted and changed in a position to swath the crop distributed along the non-straight line into a swath which is produced running along a straight swath line, wherein in the position-dependent setting and changing the working position, the one or more computation devices (4a, 4b, 5a, 5b) between a raised non-working position and a lowered working position and / or, with respect to the support frame (3), between a proximal and a distal working position to be shifted. Furthermore, an arrangement with an agricultural machine for swathing a crop on an agricultural area is provided.
