Abstract
Soybean crop elements are in the form of pods, which form from the lower part of the plant, and at high mowing heights, they may be left unharvested and loss. For this reason, it is important to correctly determine the height of harvesting soybeans. According to theoretical calculations, it was determined that when harvesting soybeans with a combine harvester, the harvesting height of the combine harvester should be set at a height of 5 cm. In experiments, when the harvesting height of the combine harvester was changed from 5 cm to 20 cm, the damage in the form of spilled pods and grain due to the effect of the motor wheel was in the range of 0.34 - 0.48 per cent, and the damage of the grain in the harvester was in the range of 1.05 - 1.23 per cent. In the experiments, unharvested pods were not observed at 5 and 10 cm mowing height, at 15 cm mowing height, such grain failure was 0.83%, and at 20 cm mowing height, it increased by 2.5 times to 2.08%. According to the results of the experiment, the productivity of the combine harvester at 5 and 10 cm harvesting height was relatively low, but the total grain loss was in the range of 1.59–1.67 per cent and did not exceed 2 per cent specified in the requirements.
