Agricultural machine

摘要

The farm machine has a processing unit for harvesting, seeds or cultivation and a detection device (10) for contact less acquisition of the process or the situation of a crop edge (11), in particular harvest cutting edge or furrow of a processing area. A control unit (12) for controlling the process of the farm machine with the captured crop edge. The detection device has an acoustic scanning sensor (8,9), which works in the audible frequency spectrum, where scanning sensor scans the crop edge in a frequency range of 10 hertz to 20 kilohertz.
