Abstract: The research subject is the process of movement of soil along the plowshare of a cultivating separating ripper – a stratification machine. The article contains particular constructive features of the implements used for cutting and elevating soil, quality and energy indexes of their operation. The author defines the estimation criteria for the development of a relatively new solution to the problem of secondary tillage effectiveness. The author describes the technological process of operation of a cultivating separating ripper with additional leading passive plane rotary disks, which ensure appropriate movement of soil along the shovel at the cultivation depth of 3-12 cm. The author considers in theory and analyzes the impact of some constructive factors on quality indexes of the implements used for soil cutting and elevating. The scientific novelty consists in usage of parallel free-rotating plane disks together with the plowshare at the same time. The author acquires the values of angle of soil friction and elevation by the plowshare giving the minimum resistance of the plowshare. In the result, the mechanical elevation and movement of soil along the plowshare of a cultivating separating ripper doesn’t give a building up effect and requires minimum energy.
