English: The choice of Soviet industrial planners was McCormick-Deering 15-30 (International Harvester), locally produced as KhTZ 15-30 in Kharkiv and STZ 15-30 in Stalingrad. The technology transfer, in forms of import and local productions of tractors, was technological backbone of the collectivization and industrialization programs during the first five-year plans. According to Antony C. Sutton “…in agriculture the transfer of Western technology was not notably successful. The hostility of the peasant, the collectivization of agriculture, the undue attachment to the imaginary massive economies of scale, and the misunderstanding of the factors making for success in Western large-scale agriculture made for ineffective transfer.”
