1977 Mercedes-Benz Unimog 406 for Sale in TN

This 1977 Mercedes-Benz Unimog 406 is a rugged single-cab example equipped with a rear-mounted Karl Schaeff HT11A folding backhoe, designed for serious off-road capability and utility tasks. The truck is finished in a practical drab green color, and it features a combination of black vinyl and cloth upholstery in the cabin. The vehicle is powered by a 5.7-liter diesel inline-six engine, mated to a six-speed manual transmission with two reverse gears, providing excellent torque for off-road performance. Key features include portal axles, differential locks, and a tilting bed, making it highly versatile in rugged environments. The truck rides on 20-inch steel wheels fitted with 335/80 Pirelli Pista PS22 tires. Stopping power comes from air-assisted disc brakes, while the coil spring suspension on each live axle helps provide stability on tough terrain. Additional equipment includes a beige soft top, snorkel, front fender flares, dual mirrors, headlight guards, spotlights, and a rear-mounted backhoe with a folding bucket and dual removable outriggers. Inside, the cabin features low-back seats upholstered in black fabric and vinyl with a body-colored dashboard and door panels. The controls for the gearbox, transfer case, and various accessories are neatly arranged ahead of the removable engine cover. The two-spoke steering wheel sits in front of a Kienzle 125-km/h speedometer and a VDO combination gauge, with the six-digit odometer showing 19,000 kilometers (~12,000 miles). The Karl Schaeff HT11A backhoe is controlled via an array of levers located ahead of a rear-facing seat. The backhoe attachment was overhauled, and is fully operational. The vehicle is also equipped with a detachable rear-mounted backhoe for demanding tasks. Under the hood, the 5.7-liter Mercedes-Benz diesel inline-six engine sends power to all four wheels through the six-speed manual transmission, with portal axles and differential locks for improved off-road performance.
