The purpose of the study is to improve the organizational and technical mechanisms for updating the tractor fleet of enterprises and individuals of the Poltava region, taking into account modern trends and transformations of the region's economy, caused by the state of war. The initial data for the study are the characteristics of purchased and registered tractors from 2018 to 2023, which are reflected in the single register for keeping automated records of tractors of the agricultural machinery registration department of the head office of the State Production and Consumer Service in Poltava region. We include the following characteristics among the investigated factors: 1. The year of registration of tractors in the unified register of automated accounting of tractors of the agricultural machinery registration department of the Main Department of the State Production and Consumer Service in Poltava region. 2. Entities registering tractor equipment are classified by groups: private individuals; farms, enterprises engaged in other economic activities. In the Poltava region from 2018 to 2021, there is a clear tendency of the generalized trend towards a stable increase in the number of purchased equipment for all three selected research groups. The beginning of military events led to a sharp – more than twofold – reduction of purchased and registered tractors and tractor equipment. The dynamics of the ratio of the use of foreign tractors and tractors of domestic production is no less a painful topic for Ukraine. In addition, the indicators of 2022 and 2023 have a negative trend towards a significant relative increase in the tractor market of the Poltava region of foreign-made tractors. The number of foreign tractor models in 2022 and most of 2023 exceeded the registration of domestically produced tractors by almost three times. To improve this situation, machine-building enterprises are recommended to master new tractor-building technologies, taking into account the experience of the world's leading manufacturers.
