The results of experimental studies on the definition of wear of the combine harvester cutter drive elements in the presence of lubricants with liquid crystals are presented. The test specifications were established according to the operation conditions of the combine harvester cutter. The linear wear of the most loaded elements of the cutter drive was tested. It was found out that introduction of mesogenic compounds into lithium lubricants allows to reduce the wear intensity of the friction pairs of the combine harvester cutter drive at the average rate of 1,54–3,39 times. It allows to enhance the loaded elements resource and, accordingly the reliability of the cutter drive operation. The results obtained make it possible to expand the sphere of application of liquid crystals as additives to lubricants widely used in agricultural machinery.
