A significant indicator of the quality of harvesting by buckwheat combines is amount of an achieved losses and quality of harvested mass of buckwheat grain. The harvest of buckwheat we can perform multiphase, double phase, and single phase. Quality of combines work depends on a numerous of factors: the state of crops, defining the relevant parameters for combine’s work, technical soundness, and operator’s skills. When the relevant parameters are not well coordinated, impairs the quality of work is significantly, resulting in increased losses of buckwheat grain and a high proportion of impurities in harvested mass of buckwheat in the combines bunker. The aim of our two-year study was to determine the amount of realized losses of buckwheat seeds by harvest device of combines ZMAJ 132 and ZMAJ 143, depending on the interspace underdrum-drum at the entrance, as well as the quality of harvested mass of buckwheat. The results allow pointing to the shortcomings and advantages of the concept applied various harvest combines. Applied methodology is standard for this issue and relates to the field-testing laboratory and exploitation, during the single-phase harvesting of buckwheat grain. The highest losses on harvesting device were recorded at combine ZMAJ 132 - 9,56 kg ha -1 (1.01%) , and the lowest at combine   ZMAJ 143- 4.28  kg ha -1 (0.45%). The highest content of whole buckwheat grains in harvested mass was at ZMAJ 143 and it was 96.32%, and lowest at combine ZMAJ 132  in  amount of 92.55%.
