Almost a third of the world’s consumption of fuel and energy resources make up the loss, that is inappropriately expended energy. It is impossible to completely eliminate the inefficient use of resources and energy. However, the implementation of energy saving programs and integrated application of energy efficient technologies leads to a reduction in the consumption of fuel and energy resources. Russia’s place in the field of energy efficiency among the economically developed countries are not the most promising, and it is determined by different factors.

The article proposes a new rotary tillage implement for the surface soil treatment, which is based on an analysis of existing designs. This tool can be used as a separate unit, or as part of combination machines. It provides an effective weed combing process, dropping them on the field surface, the simultaneous crumbling, creating crumbly soil structure and the rolled seed boxes for rake crops.

In article the review and the analysis of design features of the driveless rotary tools which are carrying out simultaneously a role of a harrow and a covering roller in modern combined units for pre-seeding preparation of soil is made. Design features of the driveless rotary tools developed in Kazan agrarian university which principles of work are founded on application of various kinds of vibrations and pulse methods of influence on processed soil are shown. The constructive scheme of new spiral toothed rotary tool is offered. The offered rotary tool is equipped by the hydrovibrator creating vibrations in a vertical plane and the spring block, ensuring self-excited vibrations in a horizontal plane. Depending on working conditions frequency of forced vibrations can be regulated by an among choke-flowmeter, and frequency of self-excited vibrations – the mechanism of change of rigidity of springs. Use a forced and self-excited vibrations in various combinations allows to increase quality of soil cultivation, to lower energy consumption and fuel rate.
