Popis: The operating test of the MOL Farm UTTO Synt oil followed after laboratory tests conducted at the Department of Transport and Handling. The laboratory test was used to investigate the effect of oil on flow characteristics of the UD 25 hydraulic pump, and samples of oil were simultaneously analysed. The UD 25 hydraulic pump is used on the Zetor Forterra 114 41 tractors. The MOL Farm UTTO Synt oil was used in the tractor transmission hydraulic circuit. The oil was sampled from the tractor in the working range of 450 engine hours (EH) and 900 engine hours. These samples were subsequently analysed in the accredited Wearcheck Laboratory at Almasfuzitő and in the laboratory for analysing ferrographic samples at the Department of Transport and Handling. At the present time, hydrostatic systems are widely dispersed in industry. They provide various types of motion. Power transmission is performed by means of hydraulic fluid. Hydraulic fluid needs service and the monitoring of operating parameters (Majdan et al., 2008). Therefore, it is extremely important to replace mineral oils with plantbased oils or synthetic oils (Tkac et al., 2010). From the viewpoint of hydraulic fluid utilisation in a machine, it is important to know the operating characteristics of a fluid, i.e. to know the effect of fluid on the technical condition of hydraulic system components (Tkac et al., 2008; Jablonický et al., 2007).
