The efficiency and intensification of breeding and seed-growing processes largely depend on equipping breeding establishments with the appropriate technical means. The most complex in design and operation of all the equipment used in the selection and seed-growing process are grain harvesters. In contrast to general production machinery grain harvesters are subject to increased agrotechnical and specific requirements due to the technology of breeding work. Analysis and evaluation of indicators of the technical level, as well as design features of grain harvesters for selection and seed production of foreign production will allow consumers to make informed decisions on their purchase and use. The most famous foreign manufacturers of special machines for breeding, seed production and agronomic research are Wintersteiger, Sampo Rosenlew, Zürn Harvesting, Haldrup, Almaco, Kincaid and Baural. The analysis showed that breeding and seed-growing combines produced by these companies usually have a hydrostatic transmission, are equipped with quick-detachable headers for various purposes and working widths, and differ in the presence of a variety of additional equipment, several options for harvesting seed and grain material (in packaging, bags, containers, bunker). Along with drum threshing machines, one and two rotary threshing machines (Almaco and Baural companies) are beginning to be used in their designs. Their power, focused on a variety of sizes of experimental plots, various stages of selection and experimental work and the amount of collected material, takes values from 20 to 160 kW, and the diameter of the threshing drum, which is the main working body of the combines, is in the range of 350-500 mm.
