Belarus MTZ-100/102/142 – Large Series of the 1980s, with Four- to Six-Cylinder Engines, 105 to 150 hp and Operating Weight from 3,750 to 5,500 kg, Built 1984 to 1993
With the MTZ-100 and related models MTZ-102, MTZ-142 and MTZ-144, the Minsk Tractor Works expanded its range with more powerful tractors in the 1980s; the register lists models from 1984 to 1993. The recorded models use four- to six-cylinder engines with a displacement of 4,750 cm³.

Recorded operating weight runs from 3,750 to 5,500 kg, wheelbase from 2,500 to 2,700 mm. Models with the II or A designation, such as the MTZ-142A and MTZ-142II, denote updated versions within the series.
The MTZ-100 series targeted larger agricultural operations inside and outside the Soviet Union with higher power needs than the smaller MTZ-80 models. For used examples, the exact model variant matters most, as cylinder count and drive type differ within the series.
With rated outputs of roughly 105 to 150 hp, these MTZ models fall within ISO 730 Category II to III for the rear three-point hitch, with a standard dual-speed power take-off at 540 and 1,000 revolutions per minute for heavy implements. The Minsk Tractor Works still exists today and continues to build tractors under the Belarus brand, so basic wear parts for the MTZ series are often still newly manufactured even for older models, and the dual-speed power take-off also allowed operation of driven harvesting machinery requiring the higher speed.

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.
- Check front and rear tyre sizes: mismatched pairs strain the drivetrain.
- 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.
