FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular, to devices for soil tillage and sowing. The unit comprises the following components installed on the frame - a tillage rotor with spade bugs and a milling rotor with discs, on which at two sides there are L-shaped knives installed. The milling rotor is kinematically connected with the tillage rotor by means of an accelerating gear. Cultivator teeth are installed between the tillage and the milling rotors in the middle of the spaces between traces of spade bugs of the tillage rotor. The distance between discs for fixation of spade bugs arranged near cultivator teeth of the first tow exceeds the distance between discs, between which there are cultivator teeth of the second row by the value exceeding or equal to the maximum width of the spade bug blade. The value of boom of the tillage rotor spade bugs beyond the outer diameter of discs for their fixation does not exceed depth of previous main tillage of soil.
