Abstract: This contribution presents the elimination of pollution for ecological fluids of UTTO (universal tractor transmission oils) type in agricultural tractors. The common oil filling of the transmission and hydraulic system is polluted by residues of old fillings from attachments such as ploughs, trailers, etc. In the tractor Zetor Forterra 114 41, a newly developed synthetic ecological fluid HEPR (VDMA 24568) was applied. The oil showed pollution limits after completing 900 engine hours. For this reason, a filtration device was designed to clean mainly biodegradable fluids UTTO. On the basis of fluid application evaluation and performed filtration, it can be concluded that a simple and affordable filtration system reduces the concentration of the most dangerous contamination particles (particles lager than 14 μm) by up to 30%.
