Zetor Crystal (UR II) – large tractors of types 8011/8045, 10011/10045, 12011/12045 and 16045 from Brno in the 1980s, four- to six-cylinder diesels from 59 to 110 kW
The Crystal series forms Zetor's in-house UR II generation, replacing the first Zetor generation, UR I, from the 1970s onward. The tractors were built in Czechoslovak Brno, where Zetor has been based since its founding in 1946. Type numbers such as 8011, 10011, 12011 and 16045 reflect the power class in horsepower in their first two digits, while pairings such as 8011/8045 or 10011/10045 denote different execution variants of the same base type within the Crystal range.

The register lists four versions here with 58.8 to 110.3 kW from four- to six-cylinder diesel engines with 4,561 to 6,842 cm³ displacement. Rated speed is 2,200 rpm, unladen weight ranges from 3,793 to 4,990 kg with lengths from 4,140 to 4,533 mm, widths from 1,950 to 2,224 mm and heights from 2,445 to 2,506 mm; torque lies between 310 and 492 Nm.
As large tractors from Czechoslovak production, the Crystal models were exported in large numbers to the Eastern Bloc countries and beyond, where alongside Soviet brands such as Belarus they ranked among the most widespread workhorses of socialist agriculture.
When buying used, check the condition of the clutch and gearbox, tightness of the hydraulic pump and steering hydraulics, corrosion on the wings, cab floor and radiator grille, and parts availability, which for this widely used series is well secured through Zetor's distribution and a dense network of eastern European specialist 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.
