The combine harvester SK-5 Niva was imported to the Czechoslovak Socialist Republic from 1974. It was used for direct and two-phase harvesting of cereals and other crops. The machine had a similar construction to its predecessor SK-4, but with a higher throughput. The main improvement was a new drum with the diameter of 600 mm and a 100k engine with a forced induction. Unlike the SK-4, the new model's reaper had a disconnectable drive that worked independently of the rest of the system. The company Ростсельмаш was founded in 1929 in Rostov-on-Don and focused primarily on the production of combines. In 1984 the company manufactured more than 2,000,000 machines.
