Development of the recommendations for the selection of rational values of the parameters of hydraulic drives of agricultural machines on the basis of the results obtained. Research methods - carrying out of computational experiments using software Mathcad, Delphi to modeling the operation of hydraulic drive power systems of agricultural machines using solids and liquids mechanic methods. Results - algorithms for computation mathematical models of the agricultural machines steering hydrosystems with the proposed dosing pump, swash plate tilt control of the axial rotor-piston pump of PVC 1.63 type, and block-separating separators for canned feeds have been developed. Within the limits of practical-research values, quasi-optimal combinations of the dosing pump parameters of a new design are recommended. Investigations of the fluid supply control system of the pump PVC 1.63 type show that the use of the effects of cylinder block pistons action on swash plate (sloping disc) can be used to generate feedback on the pump-output pressure. For this purpose, it is necessary to ensure a displacement of the pin axis relative to the axis of the cylinder block by 5 mm. The analysis of the developed structures competitiveness, including the hydraulic power drive systems of the block-separating separator of canned feed, attests to their considerable potential for practical application with real economic efficiency. The research effort results are reduced to a kind allowing their introduction into theoretical and practical application in further studies. The forecast of the expected of the research object development is the search for further constructive solutions in accordance with the recommendations developed in the process of modeling the objects of research.
