International Harvester F-Reihe – collective page of IHC's DF 25 to FS types: two- to four-cylinder engines of 2,040 to 2,356 cm³, 14.6 to 18.3 kW, diesel and petrol versions
This collective page gathers International Harvester tractors listed in the register under the type designations DF 25 (A/T), FG, FG D-2 and FS. The letter F in the type designation was used by International Harvester across several ranges, and the suffixes D and G usually distinguish the diesel from the petrol version of the same basic design, as is also visible in this grouping.

The register lists 4 versions with 14.6 to 18.3 kW from two- to four-cylinder engines of 2,040 to 2,356 cm³ displacement, two of them with a diesel engine and two with a petrol engine, unladen weights from 1,710 to 1,970 kg and rated speeds from 1,500 to 1,800 rpm; lengths range from 3,040 to 3,200 mm, widths from 1,640 to 2,000 mm, heights from 1,600 to 1,800 mm.
The F types gathered on this page cover a mid-power segment of classic field tractors and exemplify the range of drivetrain variants with which International Harvester offered both diesel and petrol tractors of the same power class across different markets.
On a used IHC F-type tractor, the condition of the respective engine counts, for the diesel versions especially the injection pump and injectors, for the petrol versions the carburettor and ignition system, along with rust on the frame and sheet-metal parts and the tightness of the gearbox and axles; because production has ended, parts are mostly only available through specialist dealers and collector circles.
