models of heavy uniaxial tractors had been introduced to the Soviet Union. For example, from 1955 on there were tests with these very vehicles in order to examine them for their possible applications. In 1956 the first indigenous prototype of such a tractor was built at MAZ. This too was extensively tested, with the goal of universal applicability. Trailers were built and tested in the form of scrapers, cement mixers, simple flatbeds and even an artificial ice rink. After completing the tests, MAZ quickly started series production of the machines. Even in 1956, the Soviet automobile industry was already so specialized that the complete train was no longer manufactured by MAZ. Only the tractor was made in Minsk, the trailer (in the standard production version a scraper) was already built at MoAZ. Since the tractor is not able to drive on its own without a trailer, a much smaller support wheel was mounted at the front to prevent the vehicle tipping over. Before normal operation, this jockey wheel was removed. These vehicles should not be confused with single axle tractors, even if they also have only one axis and are used as a tractor for attachments. A special feature of the vehicle is that no suspension was installed. Only the big tires are used for damping. In 1965 the improved MAZ-529E was built at MoAZ. It had an increased output of and was also manufactured until 1969, before being replaced by the MoAZ-546P. Production of the MoAZ-529 continued until 1973.
