The management of a modern enterprise of the agro-industrial complex should cover all aspects of the production of the main types of products produced. In this concept in modern economic conditions it is necessary to include not only economic indicators and ways of selling finished products, but also the use of modern technologies, production safety for the environment and people. Improvement of technologies for obtaining crop production is impossible without updating the equipment used for the mechanization and automation of production processes. For that reason, such a concept appeared in the legislation as certification of production technological processes, which pumps in the assessment of all technological process components, including the production means used, the quality of their technical condition and service. The article analyzes the current situation of the maintenance system, the structure and condition of the machine and tractor fleet of enterprises of the agro-industrial complex of the Omsk region. A method has been developed for processing information in terms of the agricultural enterprises revenue, and the share of work that the farm can transfer to a specialized technical service enterprise, taking into account its own profit, has been determined.

The article “Investigation of moving flat hexagonal disk attachment” reviewed the operation of flat hexagonal disk attachment used on discer for tilling the soil, exposed to wind erosion. The research of flat disk attachment is carried out in FSBEI HE OSAU named by P.A. Stolypin. The main laws are set and described and the quality evaluation criteria of cutting up weed vegetation δ in dependence upon angle of attack, cultivation depth and the distance between discs on the shaft are also represented. Using received dependences in practice it is not difficult to define the quality of weed vegetation cutting up and when required to make regulations of disc implement for quality weed vegetation cutting up. Arrangement is done by setting of basic parameters of stubble cleaner: angle of attack, cultivation depth and the distance between discs on the axle.

Possible ways to develop the sieves of cleaning machines due to indicators improvements, increasing the quality of separation are presented. Sieve vibration modes in the horizontal plane applied to the sieve-cleaning machine are considered. Regularities of the grain separation process of the flat sieves vibrating in the horizontal plane are also presented. The dependences between grain material parameters and the uniform seed distribution over the sieve area with different directions of sieve vibrations are given. It is revealed that the complication of law results of sieves vibrations increases the probability of the sieve hole that particle are entering which allows one to increase the quality of grain heap separation, thereby significantly affecting the performance of the grain machine. Circular vibrations of punching sieves with the holes set at an angle to the direction of gathering to produce grain movement on the cycloid relative to the sieve surface and spin on its axis relative to the sieve hole. This movement of grain improves the quality of its separation from weeds.
