1950 Volvo acquires BM

1950_new

In 1950 Bolinder-Munktell was acquired by Volvo, which subsequently transferred tractor production to Eskilstuna in order to free up space for expanded car production. Throughout the 1950s the Eskilstuna plant produced both green Bolinder-Munktell tractors and red Volvo tractors. The two tractor brands still kept their own separate sales networks in Sweden. Volvo tractors were favoured for exports.

 

In 1951 the first self-propelling combine harvester, the MST-91, was introduced with a harvesting width of 9 feet. Hot-bulb engines entered the history books in 1952 with the introduction of the “Bolinder Diesel Series”. Bolinder’s strong reputation was now utilised for its diesel engines.

 

One of the world’s first wheeled loaders with attachment bracket, the H-10, was introduced in 1954. The loader was based on a BM diesel tractor and opened up a whole new field for operations: tractor-based contracting machines. Volvo and Bolinder-Munktell tractors were subsequently developed to be even more heavy duty. In the middle of the 1950s, Bolinder-Munktell started to develop specialised forestry equipment based on their robust farm tractors, especially the two-cylinder Victor model. In 1957 the company introduced the world's first, small, purpose-built forest machine, which it named “Bamse". With this model Volvo’s involvement in forestry machinery began.

 

Talk of a combined BM-Volvo trademark was initiated in 1958, and the company colour became red. This was used for the presentation of the T 350 Boxer model one year later, which became a bestseller. The 1960s saw the development of BM-Volvo forestry machinery and excavators, as well as the large Bison series tractors. Cab production was centralised at the harvester plant in Hallsberg, and a six-hectare assembly plant was built around Eskilstuna in 1975. In 1973 the brand name was officially changed to Volvo BM.

 

At the 1970s Volvo decided to focus on excavators. It began co-operation talks with International Harvester, which was intended to take over sales of Volvo BM forestry machinery in North America. Volvo even began using IH components in its smaller models. The co-operation remained one-sided, however, and Volvo initiated talks with Finland’s Valmet.
