METHOD OF HARVESTING OF BIOLOGICAL YIELD OF SOYABEAN WITH STRAW CRUSHING AND THROWING AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2014 - IPC A01D91/04 A01D45/22 

FIELD: agriculture.

SUBSTANCE: inventions relate to the field of agriculture and can be used for harvesting soyabeans.
