International Harvester 933: water-cooled four-cylinder diesel engine with 3,911 cc displacement, 72 hp (53 kW) and a top speed of 30 km/h as a medium-sized standard tractor
The A series belonged to the model programme offered under the International Harvester brand in the medium power segment. The 933 occupied the upper part of that range. Series of this size formed the backbone of manufacturers' line-ups for medium-sized farms that needed neither a small compact tractor nor a heavy standard model.

The water-cooled four-cylinder diesel engine of 3,911 cc produces 72 hp (53 kW) at 2,300 rpm. At an unladen weight of 2,830 kilograms, a wheelbase of 2,150 millimetres and a width of 1,640 millimetres, the 933 is a medium-sized standard tractor for mixed agricultural use.
With a design top speed of 30 km/h, the machine falls under driving licence category T. A four-cylinder engine of this displacement at 72 hp was designed for a balanced relationship between pulling power and manoeuvrability, as required by farms with mixed field and grassland production. The power take-off on tractors of this kind runs at the standard speed of 540 or 1,000 rpm.
When buying a 933, checks should include compression, the condition of the injection pump and hydraulic tightness, as well as the condition of the clutch and gearbox. Corrosion on the wings, cab and load-bearing sheet-metal parts, together with the service history, is especially informative on a tractor now more than 30 years old.

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.
