  • Analiza osobina mazivnih sredstava za poljodjelsku mehanizaciju = Property analysis of the agriculture machinery lubricants
    Ploj, Anton
    We need to produce enough healthy and cheap food as well as to preserve the ecologic equilibrium. This can be achived by using modern machinery and up-to-date knowledge and technology. Agriculture ... machinery, in which 40-60% ofall funds are invested, is poorly maintained und underused. The main causes for this are poor knowledge and extensive farm land fragmentation. The fact that over 140.000 tractors in Slovenia are on average 9,6 years old, i.e. thatmore than 80% of overall agriculture mavhinery is obsolete, shoud be a matter of serious concern. In the paper we follow tribological conditions in particular tractor assemblies. In the first part of the paper we have treated the required conditions of tractor manufacturers in Europe and primarly in Slovenia, what has served us in the final phase of the research for elaboration of the model. In this way we have got data about the presence of particular tractor types. We have separately elaborated the necessary specifications of engine lubricants, transmission, gear, hydraulics and wet breaks. We have carried out chemical and mechanical analyses of all accesible lubricants in agriculture mechanisation. The results of the new olis were coordinated with the required specifications of tractor manufacturers and so we have got such a model, that certainly meet all lubricating requirements of our tractors.
