OPPORTUNITIES TO IMPROVE THE OPERATING RELIABILITY OF THE KSG-2,1 GRASS MOWING MACHINE IN THE CONDITIONS OF NATURAL HAYFIELDS WITH BREAKING OF THE FINGERS

Natural high-mountainous hayfields and pastures of the Republic of Armenia are the best forage base for livestock breeding. However, they are covered with superficial and half-hidden stones, which is why the fingers often break in time of gathering the feed. The finger collects grass and rolls into cutting knives and at the same time protects it from stones. It performs a very important function in the process of collecting grass and at the same time has a great influence on reliability. I have conducted studies of the operational reliability of mowing machines in case of finger breakage and revealed patterns of the occurrence and elimination of finger failures. A number of graphs, tables and equptions have been built, their analyzes have been carried out and rational methods have been recommended for increasing the durability of the fingers, consequently the operational reliability of the KSG-2.1 mowing machine.
