FIELD: agriculture; machine building.
SUBSTANCE: invention relates to agricultural machine building. Caterpillar harvester for harvesting cereals and soybeans contains reaper 1 with reel 2, cutting device 3 and screw 4, threshing-separating device 5 with grain conveyor elevator 6, straw shredder 7 and straw outlet 8. Threshing-separating device 5 of the combine is made with wind-blast cleaning 10 and two fans 11 and 12, blowing wobbly board 13 and sieves 14 and 15 on both sides.
