For sale is this nice original Bolinder Munktells BM20 Hotbulb two cylinder. The tractor was built in 1950 and spent its working life in Sweden. The tractor starts and runs well and can be started with compressed air as were many from this famous Volvo-daughter in that period. With the built-in preheater working on diesel fuel it was way ahead of its hotbulb competitors at the time.
