The results of the study of energy costs of multi-element traction transport machines are presented. The method of determining the energy costs of traction transport machines is substaniated. The energy costs of a multi-element agricultural unit are theoretically determined. The results of experimental studies of multi-element traction transport machines on the example of an agricultural unit consisting of a John Deere 8345R tractor, a hopper for John Deere 1910 seed and John Deere 1895 direct seeders. The proposed method for determining energy costs allows estimating the energy consumption of the machine as a whole or its elements. Elements of multi-element traction transport machines in the analysis of energy costs are energy-dynamic models in the form of equations of state space, which allows flexible formation of systems of equations when changing the composition and sequence of elements of the multi-element machine under study. Three ways of connecting energy-dynamic models of elements are considered: parallel and series connection and connection with feedback. It has been established that the energy expenditure by the elements of the agricultural aggregate varies according to the harmonic law with a period of 7.5 s and a transient process at the beginning of movement. The highest energy expenditure occurs in the planter 3.7·106 J with a span of 0.15·106 J. The energy consumption of the tractor and hopper is 2.7·106 J and 3.25·106 J with a span of 0.1·106 J and 0.15·106 J. Experimental studies were carried out using the measuring system of dynamics and energy of mobile machines. The fluctuations in energy consumption on the front wheels are in the same phase and those on the rear wheels are in antiphase and amount to 7.25·105 J with a span of 0.5·105 J for the front left wheel; 7.55·105 J with a span of 0.5·105 J – front right; 6.25·105 J with a span of 0.4·105 J – for the rear wheels.

Keywords: energy costs, estimation method, multi-element traction transport machine, energy.
