Abstract

Sugar beet harvesting losses was determined at 2013 – 2015 year, with different designs of sugar beet harvesting combines. Besides that it was established depend of sugar beet harvesting losses from combines driving speed. It was determined that minimum sugar beet harvesting losses were with combines who has active digging apparatus. Besides that it was established, that mini-mal harvesting losses was with combines who has combined helical – rotary cleaners and losses changed from 1,89 until 5,2 percent’s depending from the harvesting speed. It is necessary to pro-perly adjust combine cleaner and to check its adjustments during harvest. Sugar beet harvesting losses depended from harvesting speed and it was established that when the speed was increased from 2 to 6 km∙h-1, harvesting losses incresed 2, 5 times and sugar beet combine havesting speed sould not exeed 4 km∙h-1.
