CROP HARVESTING MACHINE

A crop harvesting machine has a machine body and a discharge spout attached to the machine body for overloading crop via a crop stream to a trailer. And electronic spout control and a discharge spout drive arrangement displaces the discharge spout relative to the machine body based on drive commands of the electronic spout control for guiding the crop stream to a target hit point at the trailer. A first sensor arrangement generates sensor information by optically identifying a reference feature at the trailer and detecting the position of the reference feature and/or space orientation of the reference feature. The second sensor arrangement generates sensor information by detecting a space orientation of the machine body, the discharge spout or both. The electronic spout control generates its drive commands for guiding the crop stream based on the sensor information.
