This contribution presents the results of the research into the characteristics of ecological oil labelled MOL Farm UTTO Synt in the tractor operating conditions. Biodegradable fluid was applied in the gear and hydraulic circuits of the tractor Zetor Forterra 114 41. The fluid was assessed for contamination and lubrication properties by its effect on the wear of tractor hydraulic pump during the application. The hydraulic pump was removed from the tractor at specified time intervals because of its technical condition relating to the flow efficiency. The measurements were calculated as flow efficiency with minimum environmental impact of oil on the hydraulic pump wear. Keywords:
