This publication deals with the draft of measurement chain for application of synthetic organic liquid Hydros Uni in agricultural tractor Zetor Proxima 7441. The used organic liquid was evaluated on the basis of its effect on the technical condition of hydrostatic converter UD 20. By the drafted measurement chain, it was performed individual measurements which were realized by specific engine speed and prescribed temperature. Then, the flow values were statistically analyzed. From the obtained results, it could be concluded that the proposed measurement chain meets the requirements for measuring the flow characteristics of liquids. Based on the results show, organic synthetic transmission hydraulic fluid does not negatively affect the technical condition of the tractor hydraulic pump.
