THE ANALYTICAL COMPOSITION OF THE BIODEGRADABLE UNIVERSAL TRACTOR OIL BASED ON THE VEGETABLE OILS

The basic function of the lubricant is the lubrication i.e. the diminishing of the friction between two surfaces in relative motion. Besides, they are also used to transfer power, heat transfer, cooling, corrosion protection and so on. Lubricating oils and greases are the third tribology element and their use is necessary for the proper function of almost every mechanical system. This paper presents development and testing of the biodegradable universal tractor oil based on the vegetable oils. The agricultural equipment is ideal for the use of biodegradable oils based on vegetable oils because it is used in the very proximity of the environment where the lubricant can come into contact with the soil, water and crops. This is the ideal opportunity to create permanent cycle where the agricultural equipment is lubricated by the oil from the plants grown in the fields cultivated by the very same equipment. Universal tractor oil (UTTO) is the multipurpose oil for the lubrication of the transmission, rear axle, differential, wet brakes, and hydraulic system fed by the common oil reservoir.
