Patent

CA 2297599

A self-propelled forage harvester is provided with a throughput measurement device comprising a computer which makes use of respective signals representative of the displacement of a movable upper pre-compression roll relative to a fixed lower pre-compression roll, of the speed of the lower roll, and of the force exerted by the mat of crop passing between the rolls on the upper roll once the upper roll reaches its upper limit position in the calculation of the crop throughput value. An additional input signal that may be used in the calculation of the crop throughput is generated by a light barrier which determines whether or not any crop is exiting the discharge chute of the forage harvester, this signal causing the throughput calculation to indicate zero throughput when no crop is exiting and causing the calculation to indicate a minimum amount when the upper pre-compression roll is in its lower limit position with crop being sensed exiting the discharge chute.
