UTB Universal – other models: the collective page of the Romanian Fiat licensee Tractorul Braşov, U-300 to U-703 DT, 20 to 52 kW
This page gathers the UTB Universal tractors the register could not assign to a named range – the tractors of the Romanian maker Tractorul Braşov, which built under licence from Fiat and sold worldwide under the export brand Universal, or UTB. The types 445 DTC, U-300, U-643 DT, U-650/651 M and U-703 DT give the power class roughly in the number, DT marks four-wheel drive, M an equipment variant.

The register lists here 5 versions with 19.9 to 51.5 kW from two- to four-cylinders of 1,559 to 4,764 cc, unladen weights from 1,591 to 3,380 kg, lengths from 2,805 to 3,970 mm, widths from 1,545 to 1,939 mm and heights from 1,490 to 2,500 mm, torque from 77 to 289 Nm at rated speeds of 1,800 to 2,400 rpm.
Tractorul Braşov was one of the biggest tractor makers of the Eastern Bloc and exported the Universal tractors in large numbers to Western Europe too, where they were sold under the UTB name as an affordable alternative to Western brands; the Fiat-licence origin shows in the design and engine layout of many models.
On the UTB Universal tractors, what counts is the condition and compression of the diesel engine, the condition of the four-wheel-drive clutch and axle on the DT models, the tightness of the hydraulics and lift, and rust on bodywork and cab; parts for these once mass-produced tractors are partly still available through Eastern European dealers.

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.
