Despite originally being designed as an agricultural vehicle, the Unimog had more success as a multi-purpose tool carrier. To actually serve the agricultural market, Daimler-Benz designed a completely new agricultural tractor in 1972, the MB Trac. It is a body-on-frame design "trac"-tractor, has four big wheels of the same size, and all-wheel-drive, a slim bonnet, and an angular driver cab. In contrast to conventional tractors the cab is situated between the axles, similar to comparable four-wheel-drive tractors. There is no articulation between the front and rear sections, instead, the MB Trac has conventional steering.
