FIELD: agricultural engineering tillers. SUBSTANCE: tilling machine has frame with rotors installed in row square to direction of translational movement. Each rotor is made in form of holder with knives secured on vertical shaft. Rotors are kinematically coupled with drive and are installed for paired rotation in opposite directions at distances with relative overlapping of knife rotation trajectories. Ratio of value of knife rotation trajectory overlapping to distance between rotor shafts is within 0.15 and 0.15. EFFECT: enlarged operating capabilities. 3 dwg, 1 tbl
