AB Bolinder-Munktell (BM) was a tractor and machines manufacturer founded in Eskilstuna, Sweden in 1932 through the merger of the mechanical companies Bolinders and Munktells Mekaniska Verkstad.
Bolinder are also well known as manufacturers of 'Semi-Diesel' or 'Hot bulb' engines.
In 1950 BM was bought by AB Volvo. In 1973 the company changed its name to Volvo BM AB and then in 1995 to Volvo Construction Equipment.
The product range has changed with the times. Up to the beginning of the 20th century agricultural machines such as threshers were an important product.
