A combine harvester having a tube type sensor the full width of its chaffer sieve for detecting grain loss through the vertical area between the tail end thereof and the underside of the straw walker, comprises a carrier to which the sensor is mounted and structure providing for manual positioning thereof by the harvester operator within said area at will. In another embodiment a stationary tube sensor is mounted somewhat above the chaffer sieve tail end to also indicate the effect of excessive fan speed on grain loss.
