FIELD: agricultural engineering, in particular, units for general treatment of soil on fields having a plurality of plots with soil difficult for penetration of atmospheric precipitation moisture. ^ SUBSTANCE: tillage tool has frame equipped with hitch system and tillage depth adjustment system. Frame has paired plated brackets with working tools made in the form of tines and fixed therein. Sharpened A-hoes are positioned at an angle in lower part of tines. Tines arranged in two rows one behind another are made of different length and curved to form Archimedes spirals. Tines of the second row are equipped with brackets carrying subsoilers with wedge-shaped tines and replaceable turning chisels. Disk knives are positioned forward of first-row tines, in single longitudinal-vertical plane with first-row and second-row tines. Front faces of each of said tines are formed rounded, from different materials having different friction coefficients. A-hoes have detachable stirrers. ^ EFFECT: reduced power consumption, improved quality of soil tillage, and enhanced reliability in operation. ^ 2 cl, 8 dwg |
