Abstract

In sunflower harvesting for decreasing the grain loss and increasing using efficiency of the combines GIS technologies, namely combines equipped with GPS devices and control sensors provides good results. This is explained that by the fact that with a length of 400-500 mm, the cut baskets did not partially fall on the divider-guide, and with a length of 700-800 mm, seed losses increased due to uncut baskets, since with an increase in length the divider-guide bent some stems forward and did not cut them. Analyzing the studies of working process of the adapted grain harvester combine Dominator-130 that equipped with GPS receiver and grain level indicator sensor in sunflower harvesting defined optimal parameters its header, as the following values: the length of the divider-guide (l_Т) - 0.6 m, the gap between the divider-guides (S_T) - 0.1 m, the installation angle of the divider-guide relative to the bottom of the header (β_Т) - 5 degrees. With these parameters, the combine that has adapted header for harvesting sunflower meets the agro technical requirements for harvesting sunflower.
