This paper deals with a lifetime test of the hydraulic and transmission oil, Shell Spirax S4 ATF (Universal Tractor Transmission Oil (UTTO)). This fluid was used in the hydraulic and transmission circuit of a John Deere 5720 tractor. The fluid was assessed in terms of a possible contamination of chemical elements. Fluid samples were taken from a John Deere 5720 tractor at intervals of 250 engine hours. These samples were subjected to an IR spectroscopy analysis, a measuring of the kinematic viscosity at 40°C, and differential scanning calorimetry (DSC). The spectrometer, Spectroil Q100, has been used to monitor chemical elements. [ABSTRACT FROM AUTHOR]
