FIELD: agricultural engineering, in particular, basic tillage equipment. ^ SUBSTANCE: combined tillage tool has plow-bottom surface and mellower, which are mounted on tine, and landside. Plow-bottom surface is fixed on tine by means of plates and is positioned for changing its position in vertical plane relative to tine. Mellower front edge section is made in the form of rectangular triangle with sharpening angle of 35-50 deg and hypotenuse oriented to the side opposite to direction of turning of soil layer. Mellower is fixed on tine by means of two blade graders disposed at opposite lateral sides of tine. Additional landside is positioned symmetrically about main landside with respect to tine. Both landsides are arranged in parallel with direction of advancement of tillage tool. ^ EFFECT: reduced consumption of power for basic tillage process. ^ 3 dwg |
