The water-cooled six-cylinder diesel engine of 7,983 cc delivers 66.2 kW, or 90 hp, at 1,850 rpm. At a weight of 4,800 kg, a length of 5,020 mm, a height of 2,530 mm and a width of 2,100 mm, with a wheelbase of 1,950 mm, the D4K-B reaches a top speed of 25 km/h.
A six-cylinder engine of nearly 8 litres in a tractor weighing almost 5 tonnes belongs among the heavy field tractors of its time, built for heavy tillage, pulling multi-furrow ploughs and large trailer loads on medium and larger farms, well above the power class of small single-cylinder tractors.
When buying a D4K-B, the condition of the six-cylinder diesel matters, in particular oil consumption and compression across all six cylinders, the cooling system with radiator and water pump given the engine's size, rust on the large frame and drivetrain, and the brakes given the machine's considerable weight. Spare parts for this Hungarian tractor can be sourced through suppliers specialising in vintage Eastern European agricultural machinery and heavy diesel engines of this era.

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.
