The Unimog – short for Universal-Motor-Gerät – was developed after the Second World War as an off-road multi-purpose vehicle and is built by Mercedes-Benz at its Gaggenau plant. The U 1700 of the 435 series was produced between 1975 and 1993 and counts among the larger Unimog lines of that period, with an eight-speed forward-and-reverse gearbox.

The water-cooled six-cylinder engine displaces 5,675 cm³ and produces 124 kW. Drive is taken to the rear axle with switchable four-wheel drive, shifted through an eight-speed forward-and-reverse gearbox. With a wheelbase of 3,250 mm, the U 1700 reaches a top speed of over 80 km/h; 1,161 units of this version were built.
At over 80 km/h the U 1700 exceeds the 60 km/h limit of the T tractor licence class and is registered as a lorry or towing vehicle instead. Portal axles provide the high ground clearance typical of the Unimog, while the switchable front axle keeps wear down on pure road duty. The vehicle is designed to carry implements at the front, rear and between the axles.
When buying a used example, check the condition of the portal axles, whose hub reduction gears carry their own oil supply and need regular checking. Engaging the front axle should be noticeable and free of unusual noise. Check the frame and implement mounting plates for rust, as well as the propshafts. Mercedes-Benz supplies Unimog spare parts through its own parts programme.
