Abstract
Abstract
Universal tractor transmission oil (UTTO) is multipurpose tractor oil formulated for use in transmissions, final drives, wet brakes and hydraulic systems of tractors employing a common oil reservoir. In the present work the development of biodegradable vegetable based UTTO oil has been described. The properties of formulated rapeseed and high oleic sunflower based oils were investigated in the standard test procedures and compared with the commercially available mineral UTTO oil. Tribological performances of the fluids were demonstrated by using srv high frequency test device, four ball test rig and FZG spur gear test. For final tests a laboratory hydraulic system and a spur gear test rig were used.
