Abstract
A combine harvester comprises a threshing and separating arrangement mounted to a main frame and including a threshing or separating rotor co-operating with a curved threshing or separating concave. The harvester is provided with a grain sensor having a grain detection surface which is directed to a section of the concave for directly receiving part of the crop flow from the concave and to provide a signal indicative of the quantity of grain kernels in the crop flow. The plane of the detection surface and the plane tangent to the concave section intersect at an acute angle (&bgr;). This orientation deviates the crop material sideways, such that it does not tend to stick between the concave and the detection surface itself.
