IHC G: Farmall F-12G and I 12 G – the 1932 row-crop classic with a paraffin or petrol carburettor, four-cylinder engine of 1,840 cm³ and 10.7 to 11 kW

The 1932 Farmall F-12 was one of International Harvester's first standardised small tractors, and its three-wheel row-crop chassis laid the foundation for the later Farmall range; the G versions, F-12G and I 12 G, ran on either a paraffin or a petrol carburettor. The four-cylinder engine of 1,840 cm³ delivers 10.7 to 11 kW at 1,400 rpm. The F-12 was followed at International Harvester by the more powerful F-14, before the range was replaced by newer Farmall models toward the end of the 1930s.

The register lists 2 versions of 10.7 to 11 kW from a four-cylinder engine of 1,840 cm³ at 1,400 rpm, unladen weights from 1,675 to 1,850 kg, lengths from 2,520 to 2,930 mm, widths from 1,340 to 1,900 mm and heights from 1,360 to 1,500 mm; one version delivers around 15 hp.

The F-12 and its derivatives established the row-crop layout with a narrow front axle for work between maize rows and helped make Farmall the best-selling tractor name of the 1930s in North America.

On a used example of these tractors, now eight to nine decades old, what counts above all is originality of carburettor and ignition, the condition of gearbox and clutch, and rust on wings and radiator; parts today come almost exclusively from specialist Farmall restorers and reproduction programmes.

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.
