Unimog 401

The Unimog 401 is a small all-wheel-drive tractor and equipment carrier that Daimler-Benz built at its Gaggenau Unimog plant from 1953 to 1956. It grew out of the Unimog 2010 and was the first Unimog to carry the Mercedes star on its grille. The Unimog 401 and its longer wheelbase sibling, the 402, were made 16,250 times in total. The open cab came first and a closed Froschauge, or frog-eye, cab built by Westfalia-Werke followed in September 1953. The 401 has a ladder frame, portal axles at both ends with extra reduction gears, coil springs, hydraulic drum brakes and a six-speed gearbox with two reverse gears. It is powered by the 1.8 litre OM 636 VI four-cylinder diesel, rated at 25 PS in this vehicle, and the Unimog 411 succeeded it.
