A direct connection between the organization and the repairs of the machine and tractor park (MTP) and the effectiveness of its use requires an appropriate engineering system. The existing engineering services were simplified, the organization of maintenance in most cases was left to chance. However, the physical need of the machine and tractor park remained, since it is objectively inherent in equipment and machines. A systemic contradiction arose between the required maintenance organizations and its actual implementation. Its modernization is an urgent task. In order to increase the efficiency of the organization of technical maintenance of the MTP of agricultural organizations, the system and organizational relationships of repair and maintenance services are investigated. Improving the efficiency of the operation of the MTP can be achieved by modernizing the organization of its maintenance in accordance with the adopted regulatory acts and the proposed structure of the maintenance system.
