This article discusses the prediction of the characteristics of the technical condition of machines and their effectiveness. The task of predicting the parameters of the changes the technical state of agricultural machinery during operation is to determine the numerical characteristics for future points in time. When choosing and justifying a mathematical model, it is necessary to take into account the physical nature of the phenomena that lead to a change in characteristics during operation. A model reflecting the rate of change of parameters is used to describe the processes. In forecasting, to increase the efficiency of the mathematical model, generalized physical laws are used that determine the process of changing the resource. Based on this model, it is possible to build a methodology for calculating the reliability. The set of process characteristics characterizes the change in parameters and makes it possible to predict torque functions during operation.

“…In the process of their intended use, tractors and their elements under the influence of external and internal factors lose their efficiency and consumer qualities [1][2][3][4][5]. To achieve a high level of operational reliability of tractors at the places of use, technological and organizational measures are necessary to ensure prompt and high-quality elimination of failures and malfunctions [6][7][8][9].…”

The article deals with the issues of choosing a redundancy method and the frequency of replacing tractor elements while ensuring the level of operational reliability in agricultural enterprises. It is noted that the operability of the system is ensured as long as there are reserve elements available to replace the failed main elements (and there is a possibility of switching the reserve elements into an operational state). One of the general methods for solving this problem is a method based on the use of Markov processes. In this case, the process of changing the states of the tractor is presented as a dynamic system, the state of which changes discretely in continuous time in a random manner.

“…In despite of recommendations given by the manufacturer or machine test stations [6] very often zonal operating conditions of equipment require corrections to the consumption rates of operating materials. Each machine has a number of elements that are exposed to climatic, soil, load and other zonal operational factors and due to this the parts wear out and become less durable [1]. Changes in the resource parameters of parts under the influence of the above mentioned factors, increase the duration of machine downtime for repair and maintenance and increase the related to these factors costs [5,9] accordingly.…”

When solving the problems of increasing the reliability of automotive and tractor equipment during the regular repair period, a problem of adjusting the norms of the need for spare parts appears. The lack of recommendations for their determination, depending on the operating conditions, determines the need to deepen the analysis, development and refinement of techniques in order to clarify and adjust the normalizing factors.
