Valmet (Valtion Metallitehdas - state metal factory) was a Finnish arms manufacturer that entered the tractor market in 1951. Valmet began exporting tractors in 1958, and had a factory in Brazil by 1960. In 1979, Valmet partnered with Volvo and produced tractors under the Volvo BM Valmet brand. Valmet bought out Volvo in 1985, and entered into an agreement with Massey-Ferguson to produce tractors at Massey's factory in France. Valmet had been a government-owned company until 1993, when it incorporated with Sisu. Part of this arrangement required the Valmet name to be phased out. It was replaced by the Valtra name, which had already been in use on implements and forestry machinery.
