Description:

The article is devoted to the issue of improving the methodology for determining the technical and economic parameters of aggregates for winter wheat cropping. According to the improved technique, the technical and economic indices of aggregates with domestic seed drills and crop complexes are determined. In modern agricultural production in the field of sowing aggregates, the following question arose: which tractor to use with a particular seed drill or sowing complex and vice versa. Most often, in the conditions of production, this problem is solved by the method of attempts and errors. To solve this task preliminary determination of technical and economic indicators by calculation could help. The problem is that calculations of the parameters of aggregates for sowing consider the maximum possible number of factors in order to maximally approximate the calculated parameters to the actual for further analysis, the choice of optimal composition of the unit, determining the operating modes of the unit, which will be the lowest cost of work. The purpose of this article is to improve the methodology of calculation the technical and economic parameters of aggregates for winter wheat crops in order to compare different machine aggregates by technical and economic indicators. In scientific researches of Pohoriliy L.V. [1], Natanzona I.J. [2], Gong V.R. [3], Ormanji K. S. [5] and others the issues of manning machine assemblies for substantiation of rational systems of machines and machine park has been deeply studied, methods for substantiating the rational composition of a complex of machines for the production of agricultural cultures taking into account different criteria of optimization has been developed, but very little attention is paid to the choice of optimal parameters of the work of a particular aggregate. We have carried out calculations of four units with domestic seeders and sowing complexes. In carrying out calculations, the value of hitching the tractor's engines, determined by calculation, depending on the traction effort and the coefficient of coupling of the tractor's propulsion to the ground, was taken into account.
