FIELD: agriculture.
SUBSTANCE: agricultural harvester comprises: chassis, threshing and separation system comprising at least one threshing rotor, rammed grain board, which receives plant material from threshing and separation system, wherein said sloping grain board is configured to swing in a longitudinal direction and a lateral direction, and cleaning system, which comprises upper sieve and lower sieve configured to swing in longitudinal direction and lateral direction, wherein said lower sieve is made with possibility of swinging in longitudinal direction and in lateral direction in antiphase with said rammed grain board, said upper sieve is made with possibility of rocking in lateral direction with coincidence in phase with said sloping grain board, and said threshing rotor is installed in longitudinal direction of said agricultural harvesting machine. Method for controlling the transportation of plant material through an agricultural harvester having a chassis.
EFFECT: inventions allow to avoid undesirable vibrations of threshing system and cleaning system.
