FIELD: agriculture.
SUBSTANCE: invention relates to agricultural engineering and can be used to provide workflow of the harvester with reduced grain loss. Harvester comprises a device for measuring the loss for sieve of the cleaning device. At the rear end of the cleaning device, at least behind one sieve, at least one sensor is located. The sensor is located in such a way that cleaned mass fractions falling on its surface and detected by it are fed in the direction of the harvested mass return for further processing.
EFFECT: device for measuring grain loss supports workflow of cleaning device, and detected with the sensor harvested mass fractions are fed for further processing.
