McCormick Super – the range page of the IH Doncaster classics of the 1950s and 1960s, from the Super BM to the Super FCC Vineyard, 31.6 to 37.7 kW, IH four-cylinders
This page gathers the versions of the McCormick Super range, built by International Harvester at the Doncaster plant in England in the 1950s and 1960s. The letter suffixes BM, BMD, BWD-6 and Cub distinguish body and drive variants of the range, the Super FCC Vineyard is the narrow version for viticulture; besides diesel, petrol and the petrol/TVO (Tractor Vaporising Oil) combination are also recorded as fuel, a fuel type typical of British post-war tractors.

The register lists here 10 versions with 31.6 to 37.7 kW (43 to 51 hp) from four-cylinders of 4,324 to 4,326 cm³ displacement, unladen weights of 2,450 to 2,562 kg, lengths of 3,175 to 3,510 mm, widths of 1,765 to 2,159 mm and heights of 1,676 to 1,989 mm. International and International Harvester (Great Britain) are recorded as engine makers, with the engine type IH BC 264.
The Super range is among the well-known IH Doncaster classics of those years, with which International Harvester competed in Britain and the Commonwealth against Ferguson, Fordson and David Brown; the name parts Cub and Vineyard refer to the model family and the special version for narrow vine rows respectively.
On these classics, engine and fuel system condition – on petrol/TVO versions especially the switch-over valve – clutch and gearbox, rust on bodywork and mudguards, and the originality of ancillary parts count; parts run through dealers specialising in IH classics.

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.
