A soil-cultivating unit includes a frame, a supporting wheel, a mounting mechanism and three rows of different working elements, fixed on the frame, arranged in series one after another at different depth of soil cultivation. The first row of working elements is made of spherical disks, arranged at a certain angle to the moving direction, behind which knife-like rotary blades on С- or S-like spring supports, and, behind the latters, slotting implements are mounted. |
