Zetor 5211-7745: the classic UR I series, from the 5211/5245 to the 7711/7745, 33.1 to 53.7 kW, three- and four-cylinder engines with water cooling
This series covers Zetor's first "Unified Row" (UR I), which from 1982 replaced the older Crystal tractors and carried type designations from 5211/5245 up to 7711/7745. Through the 1980s it was among the most widely built tractors of the Eastern Bloc.

The register lists 7 live models built between 1984 and 2004, including the smaller 5211/5245 and 6211/6245 and the stronger 7211/7245 and 7711/7745. Output ranges from 33.1 to 53.7 kW, weight from 2,230 to 3,835 kg, displacement from 2,696 to 3,922 cm3 across three- and four-cylinder engines.
Conceptually, the UR I tractors were simple, easy-to-maintain all-rounders for arable work and transport, often with optional four-wheel drive, built for high volumes and long service life rather than comfort.
Since the series ran for over two decades with only minor updates, early and late examples differ little technically; when buying used, the condition of the hydraulics and gearbox matters most.
In this power class of 33.1 to 53.7 kW, the ISO 730 three-point linkage is mostly built to Category I, with the PTO running at the standard 540 rpm speed. Since the UR I series was built for over two decades around shared central components, many mechanical parts – clutch, rear axle, hydraulic pump – interchange between model years and even with other Zetor series from the same era.

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.
