Bukh – other models: the collective page of the Danish tractors from Kalundborg, 302 (Super) to 554 (Super), 1950s/60s, 22 to 38 kW
This page gathers the tractors of the Danish maker Bukh from Kalundborg that the register carries outside a named range – the 302, 403, 452 and 554 types, each also listed in a Super version. In the 1950s and 1960s Bukh built, alongside the marine diesel engines the company remains known for today, also field tractors with its own diesel engines of these series.

The register lists here 8 versions with 22.1 to 37.5 kW from two- to four-cylinder engines of 2,042 to 4,503 cm³ displacement, unladen weights from 1,678 to 2,490 kg, lengths from 2,965 to 3,460 mm, widths from 1,630 to 1,780 mm and heights from 1,540 to 1,730 mm, at rated speeds of 1,800 to 2,000 rpm – all with diesel engines.
As a smaller Danish maker alongside international brands such as Massey Ferguson and Ferguson in the Scandinavian market, Bukh was mainly present on Danish family farms with mixed agriculture, where the proximity of the company's own engine production eased service and access to parts.
Used, the Bukh models call for checking engine condition and the injection pump, clutch and transmission, the cooling system, and the condition of sheet metal and tyres; parts are today offered mainly by Danish and Nordic vintage-tractor specialists, while for the engines the Bukh marine-engine service still serves in part as a point of contact.

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.
