Abstract
A device for indicating grain loss resulting from unthreshed heads in a combine harvester using a microwave transmitter-sensor. The device provides an output signal whose magnitude is a function of the mass of passing effluent which when compared to that of a typical threshed head provides a measure of unthreshed head grain loss. The device further provides that the output signal for unthreshed heads is distinct from that of loose grain providing means of distinguishing unthreshed head grain loss and loose grain loss.
