FIELD: agriculture. ^ SUBSTANCE: proposed unit has a frame, cutting discs, liquid-filling connection pipes, leveller-roll, cistern, pressure-pipeline, switching device, pressure hose and a manifold-pipe. The cutting discs are arranged in four rows with the concave surface of each row opposite the concave surface of the discs in the next row, and are cutout. Each cutout disc has a separate elastic suspension. The liquid-filling connection pipes have deflector caps and are mounted on the convex side of the discs in the second row. The cross-sectional area of the collector is equal to the sum of the surface areas of the liquid-filling connection pipes. ^ EFFECT: increased productiveness of the soil with considerable reduction of costs on cropping. ^ 3 cl, 2 dwg |
