ArticleThis article presents results of an experimental research of qualitative indicators of the
modern combine harvesters (Case IH Axil Flow 8230, MasseyFergusonMFT7, JohnDeereS680i,
ClaasLexion760, NewHolland CR9.80) used for winter wheat harvesting. Based on the results
obtained, determination was made regarding the productivity of combine harvesters on the field,
fuel consumption, and field conditions influence the grain loss and grain damage caused by a
harvester. When conducting the experimental research of a combine's performance on the field a study of the effectiveness of the combine JohnDeereS680i was made on different modes.
A program 'Machine Unit', designed by the authors, was used for the determination of productivity, fuel consumption and quality indicator for harvesting
