The article analyses the main factors affecting the performance of tractor hydraulically mounted systems. Adaptation of hydronic system for using a vegetable-mineral lubricating composition as a working fluid is considered. A scheme of a modernized hydraulic system, supplemented by a centrifugal cleaning unit as well as means for targeted alloying of the working fluid with additives is proposed. The results of a centrifuge study with specified parameters (rotor height H=137 mm, rotor diameter d=148 mm, rotor speed 5000 ± 50 min–1) showed its effectiveness for cleaning the working fluid from the most dangerous abrasive particles. The results of operational tests showed a decrease in the concentration of wear products in the working fluid by 2.3 times with an operating time of 1,200 motor hours of an experimental tractor equipped with a modernized hydraulic system with the use of a vegetable-mineral lubricating composition as a power fluid.
