The tillage with moldboard plows is one of the energy-intensive operations in farming. In view of this, the search of the energy saving solutions and tillage aggregates receives priority. The use of rotary tillage tools based on the working body-mover with elliptic blades, which horizontal soil reaction parts are directed to favoring grade of the aggregate, and, therefore, apart from the performing engineering perform the body-mover functions, - is one of the effective ways of the energy cost reduction. The authors offer the development of the rotary cultivators based on the working body-mover with elliptic blades. The change of their design values allows the development of various profiles tools. The use of these working bodies based on rotary cultivators will allow the energy cost reduction by the tillage process, especially in the compartments of terrain, as the use of tractors with moldboard plows for the main tillage is problematic. In many cases, these lots must be labored manually. The article describes the construction, generalizes the mechanical specifications and working modes of the rotary cultivator at the main tillage
