Abstract. The influence of the dimensions of lifting brushes, mounted on the cutting bar of a small combine, on the losses at direct harvesting of standing vine dry edible bean, was studied. The form of the brushes was cylindrical and they were mounted on the cutter-bar along the direction of travel of the machine. The diameter and the longitude of the brushes were studied as well as the distance between them on the cutter-bar. Losses at cutting were evaluated. The limits of space position of the pods by height of two new cultivars of standing vine dry bean were determined. It was established that application of the brushes could decrease the losses at direct harvesting under 12%. A brushes diameter of Ø38, a longitude, equal to the longitude of the fingers of the cutter-bar, and a distance of 76.2 mm between brushes were found as optimal.
