Abstract
A forage harvester comprises a feeder for feeding harvested crop material to the processing mechanism along a crop feed path It is equipped with a foreign object detector for signaling the presence of foreign objects in said harvested crop. The detector comprises a sensor having a detection field extending into at least a portion of said path. The sensor is substantially symmetric with respect to a direction transverse to the crop feed path and the detector further comprises a restriction system distinct from said sensor, making said detection field asymmetric with respect to said transverse direction. As a result, the detector becomes less sensitive to noise caused by the other components of the harvester.
