Abstract. This article presents the research results of the development of heavy soil, based on the use of magneto-strictive exciters, taking into consideration its features with soil, which allows us to conclude the conditions necessary for the optimum and most effective mode of the magneto-strictive vibrator. This is the conservation of the resonance frequencies of the working unit of the ripper, the change of which depends on the properties and volume of the developed soil. In the development of heavy soils with the help of external random influences on the loosening process, violates the mode of coordination (resonance) of the working unit. The system can be returned to its initial resonance state with the help of manual adjustment on its frequency, or by using an automatic system that provides a resonant mode for the ripper. Evaluation of the loosening processes shows that working with heavy soils when performing earthworks using the standard methods and mechanisms of loosening is not effective, while a more rational method is the method in which the intensification of the loosening process of the developed soil is determined by the high-frequency oscillation of the sound range. The application of this type of work activates the working units of the existing loosening machines, which allows to expand the range of work produced by these machines on heavy soils.
