The substantiation of expediency of developing and determining optimal parameters of the implement for pre-sowing soil tillage by the Strip-till technology, was presented. The technical solution of the vertical milling adapter for strip tillage of soil, which is protected by an invention patent, was developed. The analytical study of the influence of vertical milling adapter on working medium indicates the achievement of high-quality soil crushing and stirring with the adjustable parameters of cultivation depending on the conditions of its performance and the assigned quality indicators. On the basis of regulative documents, the procedure of conducting laboratory and field studies was substantiated and the experimental plant with vertical milling adapters was developed. The factors, influencing the work of the experimental plant and the optimal indicators of quality of the technological process, were defined. We established the dependence of the parameters of tillage quality on the adapter parameters, according to which the maximum content 77.5 % of fractions with optimal diameter from 0.001 to 0.005 m and from 0.005 to 0.01 m in the cultivated layer is achieved at angular rotation velocity of the adapter disks 26.5 s–1 and velocity of translational motion 2.2 m/s; the optimal value of density 1.2 ... 1.25 g/cm3 is achieved at angular velocity of rotation of adapter disks 14…16 s–1 at different values of velocity of translational motion; the maximum content of plant residues 79 % of optimum size from 0.005 to 0.03 m is achieved at angular velocity of rotation of adapter disks 26.5 s–1 and velocity of translational motion 1.2 m/s.
