Agricultural production is dispersed in huge areas and requires the transfer of a large number of technological and operational materials, intermediate and final products. Therefore, in the agricultural sector, transport occupies an important place: it begins and completes the processes of crops production and livestock products and carries out technological connections between individual states of work. With the development of agricultural production, the role of transport is steadily increasing: if at present, at the average 45...50 tons of different cargoes is the share of each hectare of ploughed field, then in the coming years, an increase of this volume is expected. For more than 35% of the volume of the main work types is the share of transport works which are carried out by tractors in the agrarian sector. Increasing the dynamic and energy indices of tractors during transport operations in the agrarian sector by ensuring their functional stability will lead to lower energy consumption, increase the ecological efficiency of transport processes and will ensure a steady increase in profits in the agro-industry. The concept of the formation of tractor functional stability during transport works, which is based on the reduction of amplitudes of accelerations (slowdowns) in a three-dimensional geometric space, which, unlike the known ones, provides reduction of additional energy costs, is substantiated in the article.
