Altai T, DT-54 to T-4A – crawler tractors from the Altai Tractor Plant in Rubtsovsk: 39.6 to 95 kW, 5,400 to 7,960 kg unladen weight, four- and six-cylinder diesels
The Altai Tractor Plant in Rubtsovsk, in the Soviet-era, now Russian, Altai region, built, alongside wheeled tractors such as the DT-54, above all the T-4 crawler tractor and its development, the T-4A, for heavy tillage. The digit in the designation orders the generation, and A marks the updated version. The Rubtsovsk plant was one of several Soviet tractor factories built as part of the industrialisation of Siberia from the 1940s onward.

The register lists 3 versions with 39.6 to 95 kW from four- to six-cylinder diesel engines at 1,300 to 1,600 rpm. Unladen weights range from 5,400 to 7,960 kg, lengths from 3,660 to 4,650 mm, widths from 1,865 to 1,952 mm and heights from 2,300 to 2,840 mm.
The heavy crawler tractors were designed for large-scale tillage on the kolkhozes and sovkhozes of Siberia and Kazakhstan, where their low ground pressure and high drawbar pull were needed on the vast, often damp steppe fields. Mounted implements such as multi-bottom ploughs, cultivators and seed drills were carried via the three-point linkage or the tow hitch, depending on the tractor version.
When buying used, what counts is the condition of the undercarriage and tracks, the compression of the diesel engine, the clutch and final drives, and corrosion on the frame and panels; parts for this Soviet-era series are today only available through specialist dealers in the post-Soviet states.

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.
