Case IH Magnum 7100 and 7200 — the big six

The Magnum was presented in 1987 as successor to the International 50 in the standard tractor role; series production began in 1988. The first range carried the numbers 7110, 7120, 7130 and 7140 — four large tractors, later joined by a fifth model.

What they share is the engine: a turbocharged six-cylinder of 8.3 litres. Rated power across the range ran from 155 to 230 hp, with peak output reaching up to 246 or 264 hp at the top. The rising number therefore maps the power step, not the machine size — all models share the same base tractor.

In 1997 the 7100 range became the 7200, again with five models, the 7250 closing it at the top. The Pro designation marks the revised version. Later came the MX Magnum range, with which Case IH carried the visually ageing concept forward.

For the used market this means a 7120 and a 7220 are closely related but roughly a decade apart. Comparing two offers, do not look at the number alone but at year and version — the figure describes a position in the range, not the age of the machine.

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.
  • Load the hydraulics and watch for sag.
  • Ask about parts availability for this build year — the running costs hang on it.
