International Harvester Common Market – three-cylinder diesels for the European market, types 423 to V 453/E 453, 2,536 to 2,934 cc, 29 to 35 kW
This International Harvester range gathers tractors the maker designed specifically for the European market of the European Economic Community, listed in the register under the name Common Market. International Harvester ran its own plant in Neuss on the Rhine for European sales, where types such as the 423, 523 and V 453/E 453 listed here were built for the continental market. The V variant of the 453, with a markedly narrower track, complemented the standard E 453 type with a version for narrow row crops.

The register lists 3 versions here with 29.3 to 35.1 kW from three-cylinder diesel engines of 2,536 to 2,934 cc at 1,900 to 2,200 rpm, kerb weights of 1,720 to 2,440 kg, lengths of 2,895 to 3,090 mm, widths of 997 to 1,815 mm and heights of 1,441 to 1,925 mm.
With their three-cylinder class, the Common Market models covered the mid power segment and competed in Europe with Fiat, Deutz and Ford, while the narrow V version served a niche of special-crop holdings in viticulture and fruit growing.
When buying a used Common Market model, the key points are the condition of the engine and injection pump, wear on clutch and gearbox, and corrosion on mudguards and chassis; since International Harvester folded its tractor division into Case IH in 1985, spare parts today are mainly available through dealers specialising in vintage machinery.

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.
