Abstract
Aim. Reduce the weight loss tsukronosnoyi separation process sugar beet tops of heads of roots by creating conditions for automatically adjusting the cutting height tops. Methods. The study was conducted on a new experimental laboratory-developed field installation with further processing of the results on a PC statistical methods. Results As a result of the processing results of the study confirmed the hypothesis that the distribution of protrusion heights Root heads above ground does not deny the law of normal distribution. Established limits of its statistical characteristics, which have the following meanings: standard deviation - at 20- = 30 mm, expectation - t = 40- 60 mm. Pronunciation Designed and manufactured completely new laboratory and field installation and conducted her experimental studies confirmed the hypothesis of normal distribution law protrusion heights roots and gave every reason to develop a new system of automatic cutting height adjustment tops of heads of sugar beet root crop harvesting machine on modern technical level.

Key words: sugar beets, harvesting machines, losses, sugar weight, height of protrusion, statistical distribution.
