The solution of the problems of the agro-industrial complex depends to a large extent on the provision of highly efficient mobile energy facilities, the availability of which is provided by a standard size series. The construction of the size range is based on the main parameters that should most fully characterize the technical, operational and technological capabilities of the product and have greater stability than the auxiliary parameters. It has been established that there are at least three approaches to the justification of the standard size series of power tools: according to the nominal tractive effort. On power of the installed engine, by annual load. In accordance with this, we can distinguish three main parameters for which there have been attempts to justify the size series, namely: nominal tractive effort, Installed engine power and annual load. The named parameters are disjointed because their rationale was taken in consideration of the various problems that need to be solved. The foregoing circumstances make it difficult to apply economically viable approaches to designing, manufacturing and ensuring the effective use of energy resources, which has led to the search for other, or additional, main parameters for constructing a standard size range of mobile power tools. The studies were carried out by analyzing the influence of the investigated parameters on the characteristics of energy facilities and their stability within the limits of the possible classes of the standard size series. As a result of the studies carried out to justify and improve the size of a number of mobile agricultural energy products, it has been established that, in order to provide the most informative information about mobile energy facilities, which is laid down in the main parameters of their size range, the latter can be represented as a multiparametric one, the main parameters of which are appropriate to take the nominal traction Power, engine power and level of versatility. These parameters will give an idea of the traction capabilities of the energy source, its energy potential and the availability of technical means for implementing traction capabilities and installed capacity.
