Background
Hanomag (Hannoversche Maschinenbau AG) was a German producer of steam locomotives, tractors, trucks, and military vehicles in Hanover. During World War II, the car plant made military vehicle engines, a military version of their heavy tractor renamed the SS-100, and halftrack troop carriers. The single most important and iconic military vehicle to be designed and built by Hanomag during World War II was the Sd.Kfz. 251 half-track (commonly called simply "the Hanomag") with a total production numbering just over 15,000.
The Hanomag RL 20 wheeled tractor was manufactured from 1937 to 1942. The 1.9 litre, four-cylinder diesel engine produced 20 HP. At the beginning of WWII many of these tractors were put into service with the German Wehrmacht.
