SUBSTANCE: sowing combine comprises a wheel tractor 6 with paired front and rear wheels, a sectional soil cultivating sowing tool with a central section 20, installed behind the tractor 6, a hopper for seeds and fertilisers 12, installed above its rear bridge. The hopper 12 is made in the form of two separate reservoirs arranged symmetrically relative to a central longitudinal axis of the tractor 6, and with the help of stands hingedly fixed to external cantilevers on hubs of the rear additional wheels 30, with the possibility of rotation around their axis. The combine comprises additional sowing sections installed in front of the central 20 half-frame 20 and mounted hingedly on the front half-frame 7 of the tractor symmetrically in a mirror-like manner, relative to its central longitudinal axis. The additional wheel 30 of each rear wheelset is fixed hingedly to the axis of the main wheel. Each of reservoirs in the hopper 12 has its own frame, which rests against the additional hinged supports arranged on the tractor body with the possibility of rotation around the axis. The front end of a tool trailer beam 32 is fixed to a hinged joint 33, arranged under the tractor frame. The hinged joint 33 has three extents of angular freedom. The rear end of the trailer beam is fixed hingedly on a trailer connecting rod 27 via a hinged link and has two extents of angular freedom. Both ends of the trailer are retained from possible linear movements in various planes.
