Abstract
In Armenia the mountainous natural hayfields are the best fodder base for cattle breeding. However they are covered with superficial and slim stones, straw, bushes, located on curve surfaces and in that conditions the operational results of feed harvest machines are low. In mountainous hayfields based on ÐС-2.1 grass mowing machine statistical data results were created their uninterrupted work duration probability density's statistical diagram, reliability's, statistical and probable function's modification graphs. The durability's dispersal hysteresis of eliminating failures, statistical and theoretical functions' modification graphs. The analysis result of researches shows that the operational reliability of grass mowing machine is very low. The results are shown in table. The failures' reasons are clarified. The goal is to raise the grass mowing machine operational reliability with two ways simultaneously - to improve the landscape surface areas and make durability calculation for finger and finger beam and process rational methods of repairing them for raising their firmness.
