In the article the analysis of existing agricultural machines in a healthy state, followed by work on the maintenance system subject to the conditions of reforming of the agrarian sector. Under maintenance refers to the complex of works on maintenance of working capacity or serviceability of the products during use by adjusting, knowledgeable, filling and retaining work. For the assessment of the alternatives it is advisable to conduct morphological analysis of the entire set of possible solutions to the research problem presented in a morphological matrix, which presents the basic functions of the machine and options the subject of the forms of their implementation.
Theoretical research has provided the answer to two fundamental questions – how to change maintenance system depending on the level of development of agricultural production, and what parameters must have the system maintenance service to perform the appropriate intervention with the minimum technologically necessary costs of resources and investment. Assessment of the level of maintenance of agricultural machinery is provided to carry on the totality of organizational and technical factors, formalized through parts and complex indicators, in two phases. The first evaluation of using of the indicators for each factor separately. Second – assessment of a complex indicator (for all factors).
