ANALYSIS OF THE MAIN MALFUNCTIONS OF GRAIN HARVESTERS AND WAYS TO INCREASE THEIR EFFICIENCY IN HARVESTING GRAIN, LEGUMINOUS AND OTHER CROPS

The article indicates the main problems connected with technology of harvesting grain and leguminous crops (wheat, barley, soybeans, peas) other crops, as machine operator often encounters a number technological constructive malfunctions that prevent proper threshing those or directing process to significant expenditure time labor, at same crop losses. An analysis structures occur during grain, both combine itself headers for them, was made. This is especially emphasized high humidity, which significantly worsens conditions thereby increases likelihood frequent emergency stops harvesters. Constructive solutions have been revealed allow various minimal possible Based on given structures, possibility effective use harvesters implementation agrotechnical evaluation indicators, i.e. productivity, throughput capacity thresher, losses, well avoidance regular stoppages related malfunctions, should be paid special attention, considered. CLAAS LEXION designed legumes including soybean rapeseed, are basis analysis. ways improve performance shows their in production positive results, quality reliability work will obtained, increasing productivity due stops.
