METHOD OF DETERMINING GRAIN LOSS BY GRAIN COMBINE HARVESTER Russian patent published in 2014 - IPC A01D41/127 

FIELD: agriculture.

SUBSTANCE: method comprises the summation of grain loss, isolated from samples in two bounded sites. The first sample is taken from the grain-straw mass from the site on the surface of the mat laid before the passage of the combine. The second sample is taken from the uncut spikelets of the stubble part. The length of the mat and the width of the stubble part correspond to the operating width of the combine header and the length of the stubble part is equal to the width of the mat.

EFFECT: increase in accuracy and decrease in labour intensity of determining the mechanical losses of grain by the grain combine harvester.
