Mercedes-Benz U 437.4: the Unimog U4023 is a four-cylinder implement carrier with a 5,132 cm³ engine, 231 hp (170 kW) at 2,200 rpm, a top speed of 89 km/h and a weight of 7,500 kg, built in 2013
At Mercedes-Benz, the Unimog has stood for an off-road universal implement carrier since the 1950s. The U4023 in the U 437.4 series belongs to the heavy Unimog generation of the 2010s, built for tasks demanding high off-road capability and heavy payloads.

The four-cylinder engine displaces 5,132 cm³ and produces 231 hp, or 170 kW, at 2,200 rpm, delivering 900 Nm of torque, and is water-cooled. On a 3,850 mm wheelbase the U4023 weighs 7,500 kg. With a top speed of 89 km/h it reaches, despite its weight and off-road ability, a high road speed for an implement carrier.
The heavy U 437 series combines portal axles and long suspension travel with a powerful four-cylinder turbodiesel, making it as suited to extreme off-road use, disaster relief and fire service as to heavy attachments in agriculture and municipal work. The frame is designed to flex so that all four wheels keep ground contact on rough terrain, and power take-offs and hydraulic couplings front and rear allow continuous work with changing attachments.
When buying a used example, check the condition of the portal axle gearboxes and their differential locks, the tightness of the hydraulics for attachments, rust on the torsionally stiff frame, and the ratio of engine hours to mileage. Spare parts are readily available through the Mercedes-Benz Unimog network.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Check the weights in the papers against the figures here — attachments change them.
- Shift the gearbox cold and warm — jumps only show up at temperature.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
