Abstract: A harvesting system or device formed with an agricultural harvesting machine having a crop transfer device that that swivels about a swivel angle (?) for transferring crop and allows for setting a setpoint swivel angle (? soll) for discharging the crop, and a hauling vehicle that receives the crop. The crop that is discharged from the agricultural harvesting machine impacts the hauling vehicle at an adjustable impact point.
