Condition monitoring is a necessary element of the transport and special machinery in agriculture. The task of the control operations other than the determination of the technical state of the object is to determine the required amount of work, as well as rational amount of collateral the repair of which could be combined with the next maintenance. Based on the results of processing of the information, we may generate requests for service. In the conditions of uncertainty of receipt of requests for servicing of individual machines, estimated volumes and timing, we have am appropriate development of applied technique of justification of the number of diagnostic posts for interactive control of a technical condition of vehicles and special machinery in agriculture. The presented methodology is based on probabilistic methods, and allows the quick optimization of the number of existing posts interactive diagnostics in the enterprise, if necessary, translating the existing posts in "standby" mode, or Vice versa, returning from a reserve in "work" mode. The production and technical base of the enterprise service based on the specific assumptions are considered as a system of mass service (SMO), and the function of such a SMO – as the process of mass service. The process of queuing as applied to interactive diagnosis are "Markov" processes "death and reproduction" with a finite or countable number of States and continuous time. To describe the states of the system we use the system of the Kolmogorov equations for steady state of "Markov" process. On their basis, we have determined average queue length, time of stay orders in the queue, number of busy channels and the bandwidth of the CFR. Using the intensity of the requests and the service time of a single application for specific equipment, the article establishes the efficiency of online diagnosis posts. The result of the proposed applied methodology enables timely decision-making about the need for reconstruction or technical re-equipment of the company

One of the promising directions of development of agriculture of the Russian Federation is to increase the production, improve the quality and decrease the cost of potato cultivation. Annual cleaning is one of the most intense and costly in transport and technological processes. Potatoes - blending high culture and very picky about cleaning. The highest yields and income from potato production get where embedded technology to optimize energy and labor costs. The main (though not only) the special technical means used during machine harvesting potatoes, are potato harvesters. The main problem when cleaning is a problem of balancing conflicting requirements to the process and possibilities of agricultural machinery. Including increasing the purity of the tubers in the container with one hand, minimization of losses and damages of tubers on the other hand, when the performance of equipment. In this article we propose a circuit-design solution separating the working body of the potato harvester that allow for cleaning to significantly reduce the amount of traumatized potatoes in the process of separating soil and vegetable impurities, creating the preconditions for the elimination of damage to the tubers on the hard side of the working bodies of harvesting machines. Informed choice and timely use of plug-in modules (separating working bodies) in modern potato harvesting machines at work in specific climatic conditions allows them to fully match the list of regulated agronomic requirements. Thus, the creation of new science-based technical solutions for a separation of the organs of potato harvesters is an actual scientific-technical task, which makes a significant contribution to the development of the country

The article deals with the theoretical base of the research work on the basis of modeling of secondary separation in a potato harvester
