The WF Trac (originally MB Trac) is a tractor developed by Mercedes-Benz based on their Unimog platform, built between 1973 and 1991. Manufacture has since been by Werner Forst- und Industrietechnik (Werner foresting and industrial technology) in Trier, Germany.

HistoryEdit

The Unimog idea was quite successful, except as originally intended as an agricultural platform. Daimler Benz produced a new vehicle in 1972, the MB Trac to be more oriented to larger scale mechanical farming. The new tractor crossed the Unimog technology of all-wheel drive and a power transmission to four large equal-sized wheels, with the appearance of a tractor: slim hood, behind it an angular, highly rising driver cab. In contrast to conventional tractors, the cab is situated between the axles, similar to large "four wheel drive" wheel loader - however, the steering is not by an articulated front and rear section, but with a normal steerable front axle, unlike most manufacturers of high HP tractors.

From the initial MB-trac 65 and MB-trac 70 models (later the 700), a broad platform developed up to the heavy duty MT-trac 1800 within a few years. Nevertheless, the MB-trac was not a huge sales success. Daimler Benz later merged the MB-trac with the agricultural machinery activities of Deutz AG. The manufacturing of the MB-trac series then ended in 1991, when the production was taken over by Werner. 41,000 vehicles were produced of the original MB Trac, 30,000 are believed still to be in service.

Werner produces the WF-Trac in three engine variants; it is still sold and maintained by the Unimog dealership network. It is focused less on farming, but more to the forestry sector.
