The Unimog is a line of multi-purpose tractors, trucks and lorries that has been produced by Boehringer from 1948 until 1951, and by Daimler Truck since 1951.
The hot-bulb engine, also known as a semi-diesel, is a type of internal combustion engine in which fuel ignites by coming in contact with a red-hot metal surface inside a bulb, followed by the introduction of air (oxygen) compressed into the hot-bulb chamber by the rising piston. There is some ignition when the fuel is introduced, but it quickly uses up the available oxygen in the bulb. Vigorous ignition takes place only when sufficient oxygen is supplied to the hot-bulb chamber on the compression stroke of the engine.
MB-trac is a range of agricultural tractors developed and produced from 1973 until 1991 by Mercedes-Benz Group, formerly known as Daimler-Benz. It is based on the trac design principle for tractors and shares its drivetrain with the Unimog. Mercedes-Benz offered the MB-trac in light duty, medium-duty, and heavy-duty versions in four different type series: 440, 441, 442, and 443. About 41,000 MB-tracs were made by former Daimler-Benz, before the manufacture was sold to Werner Forsttechnik in the early 1990s, who developed the WF trac skidder from the MB-trac.
Eicher tractor was a manufacturer of tractors, agricultural machinery and engines. The company was founded in 1936 by the brothers Josef and Albert Eicher in the Upper Bavaria town of Forstern.

The Lanz Bulldog was one of the most popular German tractors, with over 220,000 of them produced in its long production life. The name "Bulldog" is widely used in Germany as a synonym for tractors even today, especially in Bavaria.

ZT 300 refers both to the initial ZT 300 model, and the ZT 300 series. In total, 72,382 units of the ZT 300 series were made. The model with the highest production figure was the ZT 303, which was introduced in 1972. It features an automatic all-wheel-drive system; in the early 1980s, it cost 81,000 Mark. Starting in 1983, the ZT 300 series was succeeded by the ZT 320.
The Unimog 406 is a vehicle of the Unimog-series by Mercedes-Benz. A total of 37,069 units were manufactured by the Daimler-Benz AG in the Unimog plant in Gaggenau from 1963 to 1989. The 406 was the first medium duty Unimog, having a larger wheelbase of 2380 mm and more than twice the engine power of the Unimog 401. Unlike the initial Unimog, the 406 does not have a car engine but a heavy duty truck engine instead. Several following Unimog versions were based on the 406. There were eleven different types made of the Unimog 406, which were available in four models with a closed two-door or four-door cab, as Cabrio and as an OEM part. During its long production period, the 406 received several technical refinements. In 1964, the precombustion chamber diesel engine OM 312 was replaced with the direct injected OM 352. Disc brakes followed in 1973. For many enthusiasts, the Unimog 406 represents the classical Unimog, having agricultural and silvicultural applications. It was successful and the best embodiment of the word Universal-Motor-Gerät considering all prior Unimogs.

For political reasons, there were no successors to the H6. Such had been developed, but production of the smaller IFA S 4000-1 commenced at IFA's Werdau plant instead.
The Unimog 425 is the first series production heavy duty Unimog series, made by Daimler-Benz from 1975 to 1988 in the Mercedes-Benz Gaggenau plant, alongside the long-wheelbase model Unimog 435. It was first presented to the public on the 1974 DLG show in Frankfurt, then named Unimog U 120, indicating a power output of 120 PS. However, series production models were equipped with 125 PS or 150 PS engines, and therefore called U 1300 and U 1500. Daimler-Benz made three types of the Unimog 425, and a total number of 3135 were built, making the 425 much rarer compared to the longer wheelbase, but otherwise similar Unimog 435, of which more than 30,000 were built. The 425 was the first Unimog to feature the "edgy cab", which is still used in the Unimog today.
The MAN 630 is a five-tonne lorry, made by German manufacturer Maschinenfabrik Augsburg Nürnberg, from 1953 until 1972.

The Unimog 405 is a vehicle of the Unimog-series by Mercedes-Benz, made by Daimler Truck Holding AG. Developed in the 1990s, the Unimog 405 has been in production since 2000. Originally, DaimlerChrysler produced the Unimog at Gaggenau; in 2002, production was moved to Wörth am Rhein. The Unimog 405 is the implement carrier version of the Unimog and the successor to most previous Unimogs. Although retaining many characteristics typical of the Unimog, the 405's axle and chassis design concept with control arms instead of torque tubes marks a "paradigmatic change" in Unimog design.
