The name Unimog is an acronym for the German "UNIversal-MOtor-Gerät", Gerät being the German word for a piece of equipment (also in the sense of device, machine, instrument, gear, apparatus). It was created by German engineer Hans Zabel, who made the note Universal-Motor-Gerät on one of the technical drawings for the Unimog. Later, the Universal-Motor-Gerät was shortened to the acronym Unimog. On 20 November 1946, the name Unimog was officially unveiled. Since 1952, Unimog has been a brand of Daimler Truck. The first model was designed by Albert Friedrich and Heinrich Rößler shortly after World War II to be used in agriculture as a self-propelled machine providing a power take-off to operate saws in forests or harvesting machines on fields. It was designed with rear-wheel drive and switchable front-wheel drive, with equal-size wheels, in order to be driven on roads at higher speeds than standard farm tractors. With their very high ground clearance and a flexible frame that is essentially a part of the suspension, Unimogs are not designed to carry as much load as regular trucks.
