Info

In the autumn of 1972, the MB-trac was introduced. It utilized many components from the Unimog. All wheels were the same size, and the cabin was positioned in the center between the wheels. Work equipment could be attached to the front, rear, and on top of the back. The front lifting device and front power take-off were optional extras. The first MB-trac, known as 65/70 (65 hp DIN, 70 hp SAE), was equipped with a 3.8-liter engine developed from the engine used in MB’s trucks. The transmission featured a directional reverser with 16+16 gears.

Air-operated functions included locking of the front and rear differentials, power take-off clutches, the four-wheel drive clutch, and trailer brakes. The cabin had a flat floor and was, overall, truck-like. The front axle was sprung. Cold starting was implemented using ether injection. The lifting hydraulics lacked draft control. There were also no steering brakes. However, the main obstacle to the widespread adoption of the MB-trac was primarily its high price.

The data has been collected primarily from brochures. In some cases, sources contain conflicting information. In such cases, we have attempted to select the most reliable information. There is particularly significant variation in speed data, which varies depending on factors such as tire size. For tires, only the size most commonly used in Finland is listed. Other changes during the model history have been addressed in the text section. For the front axle lock, the Finnish term "hammaslukko" (gear lock) is used for all 100% locks.
