Zetor 5 series (UR I) – early tractors 2511, 3511/3545, 4511 and 5511/5545 from Brno in the 1960s and 1970s, two- to four-cylinder diesels from 17 to 38 kW, Zetor's first generation

The 5 series forms Zetor's in-house UR I generation and thus the first post-war series from Zetor, built at the home plant in Brno from the 1960s. Type numbers 2511, 3511, 4511 and 5511 reflect the power class in horsepower in their first two digits, while pairings such as 3511/3545 and 5511/5545 denote different execution variants of the same base type within this generation. UR I was later followed at Zetor by the UR II (Crystal) and UR III generations.

The register lists four versions here with 16.9 to 38.2 kW from two- to four-cylinder diesel engines with 1,559 to 3,119 cm³ displacement. Rated speed lies between 2,000 and 2,200 rpm, unladen weight ranges from 1,340 to 2,444 kg with lengths from 3,040 to 3,710 mm, widths from 1,620 to 1,833 mm and heights from 1,456 to 1,620 mm; torque lies between 88 and 188 Nm.

As Zetor's first modern generation, the 5 series, with its robust and simple technology, laid the groundwork for the brand's export success into the Eastern Bloc and numerous developing countries, where it remained in agricultural use for decades.

When buying used, on these older tractors check the condition of the clutch and gearbox, tightness of the injection pump, corrosion on the wings and bonnet, and wear on the front axle and steering linkage. Parts for this widely used generation remain well available through specialist Zetor used-parts dealers in central and eastern Europe.

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.
