This thesis deals with the degradation of hydraulic oil used in the hydraulic circuit of tractor. In the first part of thesis is created a literary overview about hydraulic oils, their distribution, properties and production. The experimental part deals with degradation of hydraulic oil. There is described a process of taking samples which are then measured to demonstrate the important features of the gradual degradation of the oil. These properties are density, viscosity and amount of chemical elements contained in the oil samples. In the last part of thesis the measured results are processed in tables and graphs. The results are further evaluated and accompained by the discussion.
