Bolinder-Munktell farm tractors are a cornerstone of Swedish agricultural machinery history, combining the innovation of Munktell and the engine expertise of Bolinder. The two firms merged in 1932 to form Bolinder-Munktell (BM), setting the stage for decades of precision-built tractors. Initially independent, the company attracted interest from Volvo in the 1940s, leading to a full acquisition by 1950. The BM name held strong until the 1970s, when Volvo transitioned to branding their tractors as Volvo BM. Eventually, the tractor division was sold to Valmet, but the Bolinder-Munktell influence remains significant.
The tractors produced during the BM years became known for their robust construction, reliability in Nordic climates, and mechanical simplicity. Whether in the form of the compact BM-10 or the more powerful BM-20 and BM-21, these machines found favor among farmers across Sweden and beyond.
