Improvement of the reliability of tractors of agricultural enterprises of the Omsk region by implementing a new form in the organization of maintenance operations

The solution to the problem of improving the reliability of the machine and tractor fleet in the production conditions of agricultural enterprises is an important and urgent task of the engineering service of the agro-industrial complex. It can be solved by reducing the downtime of machines for maintenance operations using intensive methods for performing operations in the unstressed period of field work, as well as transferring part of the operations to specialized maintenance enterprises. Currently, one machine operator works on several machines and cannot perform maintenance and repair operations on time. Therefore, it is advisable to transfer to specialized enterprises part of the complex maintenance and repair work. The article calculates the costs of maintenance at two levels: agricultural enterprises of the agro-industrial complex and specialized maintenance enterprises. At agricultural enterprises, when forming a maintenance system, the dealer system can be implemented only in large enterprises with high profitability of the economy. Based on the current research, a methodology was developed for determining the economic efficiency of tractor operation when introducing a new form of maintenance in the farms of the Omsk Region. The determination of the reduction of unit costs from the removal of operations for complex types of technical maintenance during the busy period of field works and the transfer of the share of maintenance operations to specialized enterprises by the farms of the Omsk Region have proved the effectiveness of the new concept of maintenance. The organization of maintenance in cooperation with specialized centers will not only reduce the cost of organizing the maintenance of equipment, but also increase the profitability of the enterprise.
