MB-trac

Naming scheme In total, four type series (440, 441, 442, and 443) and twenty-one different series-production types of MB-trac were made, with either ten or sixteen models, depending on whether the Turbo-designated models are considered separate from the non-Turbo-designated models. The naming scheme of the MB-trac is mostly homogeneous, with MB trac followed by a number roughly indicative of the engine's DIN-PS power output times ten. Models equipped with a turbocharger have a turbo suffix in their model name, and models with an additional intercooler have an intercooler suffix instead. The exceptions to this naming scheme are the MB-trac 65/70, which has a power-output figure indicative of the DIN-PS/SAE-hp power output, MB-trac 900, MB-trac 1300 and MB-trac 1500, which have no turbo suffix despite being turbocharged, and the MB-trac turbo 900, which has a turbo prefix rather than a suffix. The MB-trac name is spelled MB-trac in technical documents, but MB trac on the tractors' bonnets.

Former Daimler-Benz had been making the Unimog, a tractor-like implement carrier vehicle, since 1951. Mercedes-Benz customers however sought a dedicated agricultural and silvicultural tractor. Thus, Daimler-Benz, on 25 March 1968 issued a development order for an agricultural tractor that would share various components with the Unimog 403. Throughout the development phase, various prototypes were built; these were designated the AM 60. During the development phase, a version with a rotating steering-column and driver seat was considered, but originally not put forward. In 1987, Daimler-Benz entered into a strategic cooperation with Deutz, who at the time built the Deutz INTRAC, a similar trac-like tractor. Joint development was carried out by Daimler-Benz (40 %) and Deutz (60 %) owned Trac-Technik-Entwicklungsgesellschaft (TTE) throughout the late 1980s, however, due to cost concerns, development was cancelled, and it was decided at Daimler-Benz to cancel the MB-trac as a result. In 1990, the MB-trac lineup saw its last and most powerful addition, the MB-trac 1800 intercooler. It was based on a 1600 turbo, but had an additional intercooler installed. Production ended on December 17th 1991. Production numbers == Technical description ==

The MB-trac comprises four different series which have distinct technical differences. The following description thus only gives a basic overview of the MB-trac. In general, the MB-trac is a trac type of agricultural tractor which is characterised by four same-size wheels, a frame undercarriage for the engine and front axle, and steerable wheels rather than articulated steering. The cab is installed in the center of the vehicle. This design allows the MB-trac to mount implements in front, on the rear axle behind the cab, and behind the rear axle. Despite sharing its drivetrain with the Unimog 403 or Unimog 425, the MB-trac is not a modified Unimog. It is distinctly different and much more suited for agricultural use, for example, due to its larger wheels. Unusual for an agricultural tractor, the MB-trac's front axle is coil sprung, which improves its on-road handling characteristics. Light-duty MB-trac models were equipped with the Mercedes-Benz OM 314 or Mercedes-Benz OM 364 four-cylinder Diesel engines and use a gearbox with 16 forward and 8 reverse gears. == Bibliography ==
