The invention is directed to a crop harvesting machine with a machine body (2) and a discharge spout (3) attached to the machine body (2) for overloading crop via a crop stream (4) to a trailer (5), with an electronic spout control (6) and a discharge spout drive arrangement (7) to displace the discharge spout (3) relative to the machine body (2) based on drive commands of the electronic spout control (6) for guiding the crop stream (4) to a target hit point (8) at the trailer (5), wherein a first sensor arrangement (10) generates sensor information by optically identifying a reference feature (11) at the trailer (5) and detecting the position and/or space orientation of the reference feature (11). It is proposed that a second sensor arrangement (12) generates sensor information by detecting a space orientation of the machine body (2) and/or the discharge spout (3) and that the electronic spout control (6) generates its drive commands for guiding the crop stream (4) based on the sensor information of the first sensor arrangement (10) and the sensor information of the second sensor arrangement (12).
