FIELD: agriculture.

SUBSTANCE: machine comprises chassis, engine, control cabin, link mechanism, and at least two working sets joined to link mechanism of agricultural machine by means of link frame. At least two working sets are arranged with the possibility of rotation between working position, in which working sets are arranged substantially horizontally and transversely to direction of working movement, and transport position, in which working sets are arranged substantially above chassis. Link mechanism is connected to chassis through rigid structure, which is connected to chassis by means of transverse hinged joint. Between chassis and rigid structure there is at least one drive to provide for rotation of rigid structure around transverse hinged joint.

EFFECT: improved efficiency, simplified design, reduced dimensions and expanded functional capabilities.
