Maintaining the required cut height minimizes losses and ensures continuous shoe contact with the surface. Thus the excessive pressure of the shoe destroys the stubble and leads to its accelerated wear, and insufficient pressure is accompanied by increased losses and provokes the galloping of the header.
An analytical solution to the problem of modeling the mechanism of the KPP-4.2 hanging is an iterative execution of the analysis procedures based on the formed hypothesis, as well as the procedures of comparison and selection of options in the procedure of parametric synthesis. It is a choice of a combination of internal parameters of the flattening device, which, while satisfying the functional limitations, simultaneously stabilize the whole mechanism.
A study and analysis of the hanging mechanism of a mower-conditioner trailed KPP-4.2 using methods of theoretical mechanics, differential and integral calculus, probability theory, mathematical modeling and computer software. A geometric model has been created for calculating and optimizing the operation of the hanging mechanism. The MVA KPP-4.2 output parameters were calculated for three different cut heights.

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.
