FIELD: agriculture.
SUBSTANCE: farm machine has at least one working tool for processing of harvested mass, first device for conveying of harvested mass, and at least one another conveying device. There is gap for passage of harvested mass, defined between said two conveying devices for harvested mass. Flows of harvested mass conveyed by means of conveying devices are passing in oncoming directions with respect to one another. Suction fan is located rearward of cleaning device and at least two harvested mass conveying devices, said suction fan creating additional air flow in the region of drop threshold between harvested mass conveying devices. Distributing device for suction fan is provided with adjustable guiding partitions and guiding member. Method involves providing vortex-free conveying of harvested mass through farm machine; laying long-stalk straw in windrow for further utilization; discharging short-stalk straw and chaff from harvesting machine without producing perturbing action upon already laid windrow.
EFFECT: increased efficiency and simplified method for conveying of harvested mass.
