Abstract

Apparatus in a combine harvester for indicating blockage of the grain cleaning means, comprises sensors (52) operable to sense the air flow through the cleaning means and provide a plurality of first signals responsive thereto, monitor means (54) responsive to the difference between the first signals and a predetermined signal for providing a plurality of second signals, and warning means (56) responsive to the polarity of the second signals. <IMAGE>
