Now with a rapidly growing Volvo as owner, BM took major steps towards becoming a highly industrialized, efficient producer of agriculture-, forestry- and construction equipment.
In 1952 the company launched its first series of diesel engines, the "105 Series" – four-stroke engines with direct injection. It was a modern engine with particularly low specific fuel consumption, high torque, outstanding reliability and, as the users would experience in due time, little wear and long service life. One of them, a three-cylinder diesel engine, was fitted in the Volvo BM35 tractor and Sweden's first diesel-powered agricultural tractor was a fact.
These engines, together with the larger Volvo 6-cylinder diesel engines, were basic elements and key components in the company's new product strategy.
