The publication highlights the theoretical principles of substantiation and optimization of the parameters of tillage machine-tractor units as one of the key factors in increasing the efficiency, productivity and energy performance of forestry production. The research is based on a systematic methodology that integrates the fundamental principles of theoretical mechanics, soil mechanics, traction theory and the general theory of machine-tractor units for the development and operation of high-performance aggregates. A comprehensive analysis of the main factors determining productivity, energy efficiency, reliability and quality of technological operations during primary tillage was carried out. Particular attention is paid to the complex interrelationships between the structural and technological parameters of tillage machines, the traction and energy characteristics of power units, soil properties and specific operating conditions.
Considerable attention is focused on the problem of reducing energy losses and improving the utilization of the traction capabilities of tractors. Modern approaches to mathematical modeling and optimization of operating parameters using traction-balance models, energy indicators and analysis of the time structure of technological operations are considered. The proposed methodology makes it possible to take into account actual operating conditions, changes in soil resistance, working speed, tractor wheel slip and the technical characteristics of the machines included in the unit.
The research results, including the developed algorithms for determining the optimal number of machines in the aggregate and rational working speeds while taking into account skidding indicators and energy limitations, can be used to improve technological processes in forestry. The implementation of the proposed approaches provides a scientifically substantiated basis for selecting the composition and operating modes of machine-tractor units, increasing productivity and economic efficiency, reducing specific fuel and resource consumption, and improving the overall energy efficiency of forestry operations.

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.
