FIELD: agricultural engineering, in particular, equipment for basic soil tillage. ^ SUBSTANCE: tillage tool has plow-bottom surface and mellower, which are mounted on tine. Plow-bottom surface is positioned in conjunction with mellower on single tine so that position of said surface in vertical plane relative to tine may be adjusted. Mellower is made in the form of chisel and supporting shoe. Working part of chisel is beveled at an angle of 40-50 deg toward side opposite to direction of turning of soil layer. Chisel working part sharpening angle is 25-35 deg. Chisel is positioned at an angle of 30-50 deg to direction of advancement, and its point is arranged at the same level with lower surface of supporting shoe. ^ EFFECT: simplified construction, reduced consumption of power for basic tillage of soil, reduced material usage, and increased soil fertility. ^ 5 dwg |
