The parameters and modes of operation of the asymmetric disc harrow for soil cultivation were studied. During the determination of parameters and regimes, the theory of dimensions and similarity of physical quantities was applied. As a result of the study, regularities were revealed that reveal the relationship between parameters, operating modes and properties of the environment with energy indicators of the process. Experimental data on the operation of an asymmetric disc harrow with spherical discs for soil cultivation were used as initial data.
Based on the theory of dimensions, dependencies were obtained to determine the dimensions of the parameters and modes of operation of the disc harrow with spherical discs for soil cultivation and soil properties, such as traction resistance, depth, grip width, speed, soil hardness and acceleration. Similarity criteria were also determined on the basis of this theory.
With the help of correlation analysis and the method of least squares, the nature of the dependence and the corresponding coefficients were determined. A schedule was built to determine the operating modes and parameters of a disc harrow with spherical discs for soil cultivation.
To represent the dimension of each quantity that is included in the established formulas, in the form of a product of power functions of independent quantities (length L, time T and mass m), we can use the method of dimensional units.
On the basis of the obtained dependencies, it is possible to solve tasks related to determining the traction resistance of technical means for soil cultivation with disk harrows. Literary sources and well-known scientific studies in the field of soil cultivation with the technical means of a disk harrow were used as input data. Therefore, the conducted research made it possible to establish important relationships between the parameters and modes of operation of a disk harrow for soil cultivation using the theory of dimensions and similarity, which can be useful to improve agricultural production processes.

Technology, energy, agriculture transport AIC is a scholarly professional journal with a long-standing history and stable academic tradition, reflecting the evolution of engineering and technical sciences within the agro-industrial sector of Ukraine.
The journal was founded in 1997 under the title Bulletin of Vinnytsia State Agricultural Institute. According to the Resolution of the Presidium of the Higher Attestation Commission of Ukraine dated September 11, 1997, the publication obtained the status of a professional scientific journal, which enabled the publication of the main results of doctoral and candidate dissertations in technical sciences. From its inception, the journal positioned itself as an academic platform for addressing current issues of mechanization, electrification, and technical support of agricultural production. During 2001–2014, the journal was published under the title Proceedings of Vinnytsia National Agrarian University. Series: Technical Sciences (State Registration Certificate of Print Media KV No. 16644-5116 PR dated April 30, 2010). Throughout this period, a systematic approach to the selection and peer review of scientific manuscripts was established, the thematic scope of publications was expanded, and continuity of scientific directions as well as the development of sectoral engineering schools was ensured. Since 2015, the journal has been published under its current title, Technology, energy, agriculture transport AIC (State Registration Certificate No. 21906-11806 R dated March 12, 2016). The change of title reflected the expansion of the journal’s thematic coverage and its orientation toward interdisciplinary research in mechanical engineering, energy systems, electrical engineering, transport technologies, automation, and digital solutions for the agro-industrial complex.
