Universal Tractor Transmission Oil (UTTO) is a multi-functional tractor oil formulated for use in transmissions, axles, and hydraulic systems of tractors employing a common oil reservoir. In the present work the development of biodegradable vegetable based UTTO oil is described. The properties of two rapeseed and two high oleic sunflower based oils were investigated in the standard test procedures in comparison with the commercially available mineral UTTO oils and fast biodegradable synthetic esters. At first stage, the physical and chemical properties of oils were determined. Tribological performances of the fluids were demonstrated by using SRV high frequency test device, Four Ball test rig and FZG spur gear test. Through simulating real working parameters in a tractor hydraulic system, a model hydraulic system is used. The results of this study demonstrate that it is possible to formulate the vegetable base UTTO oil with mechanical properties comparable to the mineral UTTO oils.
