The purpose of the article is to investigate the quantitative and qualitative changes at the market of self-propelled combine harvesters in Ukraine and to substantiate the main criteria for decision-making by the management of the agricultural enterprises in the formation of their fleets.

Research methods. The methodological basis of the research is the dialectical method of cognition of the processes and phenomena, scientific works of the domestic scientists on the problems of formation, development and functioning of the agricultural machinery markets. The following research methods have been applied to solve the problems set in the work: monographic (for analyzing the peculiarities of the formation of the combine harvesters market in Ukraine), empirical (for complex assessment of the current state of the research object), abstract and logical (for generalization and formulation of the conclusions).

Research results. The current state, preconditions and peculiarities of the market formation of combine harvesters and provision with them of the rural producers have been analyzed. The factors that hinder the organization of production of complex agricultural machinery in Ukraine during the days of the state independence have been investigated. The main directions of implementation of the scientific and technological progress in the structures of self-propelled combine harvesters of the leading world producers have been analyzed. The scientifically substantiated proposals on the criteria of decision-making in the formation of combine harvesters fleets by the agricultural enterprises with different levels of production concentration have been worked out.

Scientific novelty. The theoretical provisions on the formation of the agricultural machinery market have been further developed, taking into account the introduction of the latest innovative achievements of the scientific and technological progress in agricultural machinery construction and structural changes in agriculture of Ukraine.

Practical significance. The main technical and technological, economic factors influencing the formation of the self-propelled combine harvesters market in Ukraine have been identified. The proposals for determining the criteria for managerial decisionmaking in the formation of combine harvesters fleets by the agricultural enterprises with different levels of production concentration have been developed.
