The comparative characteristic of the used soy gathering combine harvesters is provided in the article; it is established that energy consumption is one of the criteria for the reliable determination of the combine harvester park use. The issue about the combine harvester choice optimization on soy gathering is considered on the basis of the importance coefficients that allow to find the optimum decision on their distribution with the minimum energy consumption.
