International Harvester – other models: the collective page of tractors outside the named ranges, from the 10-20 and 15-30 of the 1920s through the 404, 606 and 706 to the 1066 Hydro, 1456, 4186 and 7488, 11 to 235 kW
This page gathers the International Harvester tractors the register could not assign to a named range – the Chicago brand that emerged in 1902 from McCormick and Deering, invented the row-crop tractor with the Farmall in 1924 and was the world's largest tractor maker into the 1960s before being absorbed into Case IH in 1985. The type logic changed over six decades: the early 10-20 and 15-30 types give drawbar and belt power in hp; the 04 series of the 1960s (404, 504, 606, 706, 806, 1206) orders the size in the first digit and carries with the 1206 the brand's first turbodiesel; the 56 (656, 856, 1056, 1256, 1456), 66 (1066, 1466) and 86 series of the 1970s follow the same logic with Hydro as stepless hydrostatic transmission; the articulated 4100 to 4186 and 7288 to 7488 (2+2) are the big tractors; the industrial versions carry the suffix Industrial. The engines come from IH's own plants in Chicago (Melrose Park), Neuss and Doncaster, as petrol, LPG and diesel versions; Nissan and Mitsubishi engines sit in the Japanese compact tractors of the 1980s.

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.
