Munktells AC, AE and AF Tracked Tractors

During the war years, around 80 tracked tractors were made for the Swedish Royal Air Force Materiel Administration and for use on peat bogs. Three types of engine were used. The Air Force Materiel Administration had six-cylinder Volvo engines such as the BM 4, but these were adapted to be powered by "motyl", a mixture of alcohol and gasoline.
Scania Vabis engines were also used for producer gas operation and ignition bulb engines. The tracked tractors had four carrier wheels on either side and were steered with a steering wheel. The total weight was about 3 400 kg.
