A combined coulter unit to sowing drills of the model line cz-3.6 comprises a body, fixed to a driving beam on a parallelogram suspension with a disk, mounted at angle to the moving direction, rotating on the axis. Behind of the disk in a holder a hollow seed-duct leg is fixed in such a manner as to allow moving thereof, in the front part it is provided with an anchorage point, and in that lower &ndash； with an A-hoe blade, in the underblade space of which a seed scattered is mounted. An anchorage cleaning plate is fixed to the lower end of the body at angle to the plane of the disk, and into a gap between the anchorage cleaning plate and the plane of the disk the lower end of a fertilizer duct, which is rigidly fixed on the body in front of the seed-duct leg, enters. On the back wall of the holder a mounting bracket is disposed immovably. A frame of a supporting-rolling unit is hingedly fixed to the vertical planes of said bracket with the aid of a single finger, which is mounted into coaxial openings of the vertical planes and, depending on the height of the unit, into the coaxial openings of the regulating legs. A technological weight is rigidly fixed to the upper part of the regulating legs of the frame of the supporting-rolling unit. The basic mass of said weight is concentrated above the axis of the hinge, and the ends of the legs contact the vertical plane of the mounting bracket. An angle between the plane of the disk and the moving direction of the coulter unit does not exceeds 4 degrees, and the axis of symmetry of the seed-duct leg, the anchorage point and the A-hoe blade passes through the point of touching the soil by the disk.Комбінований сошниковий вузол до сівалок модельного ряду С3-3.6 містить прикріплений до поводкової балки на паралелограмній підвісці корпус з встановленим під кутом до напрямку руху, що обертається на осі. За диском у тримачі закріплена з можливістю переміщення порожниста стійка-насіннєпровід, яка оснащена у передній частині анкер
