UTB U (Universal) – from the U 445 to the most widely built U 650/651: 31.6 to 47.8 kW, 2,339 to 4,764 cc diesel, kerb weight 1,840 to 3,050 kg, exported worldwide
UTB's Universal range from Brașov comprises, with the U 445 and U 650/651, two very differently sized tractors from the same base family: the smaller three-cylinder U 445 and the four-cylinder U 650/651, whose simple, rugged design made it the most widely built Romanian tractor of all, exported worldwide in the millions.

The register lists 2 variants at 31.6 to 47.8 kW (the U 445 at around 43 hp) from three- to four-cylinder diesels of 2,339 to 4,764 cc, kerb weights of 1,840 to 3,050 kg, lengths of 2,920 to 4,230 mm, widths of 1,515 to 2,000 mm, heights of 2,180 to 2,480 mm, torque of 140 Nm and rated speeds of 1,800 to 2,400 rpm.
The U 650 in particular, as a rugged, easily repaired universal tractor, shaped agriculture across much of Eastern Europe, Africa and Asia, and remains in practical use in many countries today, while the smaller U 445 served smaller holdings and specialist crops.
Buying one of these simple diesels, compression and the condition of the injection pump matter, along with wear on the clutch and gearbox, the state of the rear axle and brakes, and rust on the frame and wings; parts, especially for the widely used U 650, are comparatively easy to find through Eastern European farm-machinery dealers, reflecting the sheer number of these tractors still in service.

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.
