Rostselmash

Rostselmash was founded in 1929 as a government contractor, producing a variety of products for state farms. In 1931, the first Stalinets harvesters were produced. The Stalinets-1 was awarded with the highest award (Grand Prix diploma) during the World Industrial Exhibition in Paris in 1937 and by 1940 fifty thousand units were assembled.

During Operation Barbarossa, Rostselmash dismantled its plant in Rostov-on-Don, and relocated in Tashkent, the capital of Uzbekistan. Production shifted from agricultural goods to military equipment until the end of the war. In 1943, production was returned to Rostov.

After the war, the Stalinets-6 harvesters were assembled and in 1955 Rostselmash began to specialize in grain harvester production. In 1958, the SK-3 self-propelled harvesters were introduced followed by the SK-4 in 1962. By 1969, Rostselmash produced a million harvesters. The SK Niva harvesters, introduced in 1973, remain in production for the Eastern European market.

By 1984 Rostselmash produced two million harvesters. The Don Series combines were introduced in 1986; those along with tractors were sold in North America by Belarus Tractor of Canada. Both had a reputation for poor quality, lack of operator comfort, poor reliability, and lack of part availability.

After the fall of the Soviet Union, Rostselmash was incorporated into a joint-stock company in 1992, and fully privatized in 2000. The new owners — Konstantin Babkin, Dmitry Udras and Yuri Ryazanov withdrew Rostselmash from the crisis of 1990-s.

In 2007 they took control of Buhler Industries of Winnipeg in Canada. Buhler Industries are the owners of the Canadian–built Versatile brand of articulated tractor, founded by Peter Pakosh.

In early 2024, it was announced that RostSelMash had sold all shares of Versatile Tractors (Buhler Industries) to Turkish-based Basak Traktor, which is a subsidiary of ASKO Holdings.

In June 2025, Rostselmash suspended production, citing collapsing demand as farmers struggled with capital deficiencies related to the poor economic climate in Russia. Executives and analysts cited high interest rates cutting off access to affordable financing and high export duties assessed against farmers as the principal causes of the collapse in demand.

Harvesters

Rostselmash produces four harvester variants. A 400 hp rotary harvester is sold the Rostselmash name in Eastern Europe and the Versatile name in North America. The RT 490 uses a unique Rotating Concave Rotary design where the concave rotates counter to the rotor, reducing dead spots and increasing usable area.

Vector and Acros harvesters are sold in North America through Python Manufacturing Inc.

The Niva is a 155 hp harvester developed in the Soviet era, and is available only in Eastern Europe and Africa.

Road-building machinery

In September 2021, Rostselmash announced it would develop and manufacture road building machinery, with sales planned to begin in 2023. 70% of new production is intended to be localized by 2024. Construction of the new plant for road-building machinery also began in the same month.
