An agricultural harvesting machine for harvesting and/or processing crop material has a transfer device for transferring crop material, an intake device that includes a foreign-object detection device for detecting foreign objects in a monitoring region of a crop material flow, in the case of which, when a foreign object in the crop material flow is detected by the foreign-object detection device, the agricultural harvesting machine is braked automatically, and/or at least one energy storage medium is withdrawn in order to reduce the ground speed, it being possible to adjust the value for the braking effect and/or the withdrawal of the energy storage medium.
