Known physical and mechanical properties of the mung bean and its seed is importent for harvesting and cleaning. Experiments for determining were performed according to defined methods by sorts of mash bean "Turon", "Durdona", "Kakhrabo" and "Radost" that are being grown in large amount in present days and during the experiments the fraction content of the mash bean seed as well other impurities in its content also length, width and thickness of the seed were defined. There are pure seed between 85-86 % in content of seed mixtures, about 2 % broken and free seeds as well between 12-14 % other impurities. The seed of mash bean sort "Durdona" is the biggest among other sorts, its average grain length is 6.29 mm, width is 4.25 mm and thickness is 3.96 mm. "Turon" and "Kakhrabo" sorts’ seeds have average sizes, their average seed lengths are 5.85 mm and 5.58 mm, their widths are 4.25 and 4.16 mm also their thicknesses are 3.68 mm and 3.96 mm respectively. According to size, the smallest grains belong to "Radost" sort, their sizes were defined at 4.58 mm, 3.46 mm and 3.60 mm respectively. According to researches, it was defined that there are other impurities around 11.1-11.4 per cent, free and broken seeds about 1.9-3.4 per cent in the content of mash bean that harvested by cereal harvester combine and they should be separated before using consumption or sending to sell, as well it is expedient to separate to fractions according to dimension of seed.
