49 Concentrated and accurate. The discharge. AUTO FILL. Automatic filling of trailers. AUTO FILL is based on the principle of digital 3D image analysis. By analyzing the camera images of the trailer traveling alongside, the system is capable of determining both the outer edges and the fill level at any position in the trailer. Additionally, the system is able to determine where the harvested crop will impact as it enters the trailer. The data obtained is used to control the discharge spout automatically lengthwise and crosswise in relation to the vehicle axis. This process results in optimal filling of the trailer.
