Case IH Farmall U – utility tractors from Turkey and Basildon: four-cylinder FPT engines, 52 to 88 kW, Farmall 85U to 120U models, a revived heritage name

The Case IH Farmall U is a utility range that Case IH built at its Turkish plant and at its Basildon works in the UK. The Farmall name revives the historic International Harvester tractor brand, while the U in the designation stands for Utility. The register covers the Farmall 85U, 95U, 105U and 120U models, whose number indicates the approximate horsepower class; they are powered by four-cylinder FPT diesel engines.

The register holds 4 versions rated at 52 to 88 kW (70 to 120 hp), with four-cylinder engines of 3,400 to 4,500 cm³. Weights range from 2,900 to 4,550 kg, with a gross vehicle weight of up to 7,400 kg. Lift capacity falls between 2,606 and 3,667 kg, and cab heights between 2,604 and 2,718 mm. Engine speed is 2,300 rpm, running on diesel.

As utility tractors, the Farmall U models filled the middle power segment between compact yard tractors and large all-round tractors, aimed at mixed farms with field, haulage and front-loader work. By reviving the Farmall name, Case IH deliberately drew on the heritage of International Harvester.

When buying used, check the FPT engine and its injection system, the clutch and gearbox, and the front hydraulics if a front loader was fitted. Typical checkpoints are rust on the mudguards, steps and cab frame, and the condition of the cab seals; spare parts are readily available through the Case IH dealer network.

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.
