Rated speed is 1,750 rpm. The machine is 2,732 mm long, 1,630 mm wide and 1,585 mm high. The unladen weight is 1,230 kg. The wheelbase measures 1,676 mm. Ground clearance is 395 mm. Top speed is 21 km/h. Transmission: 5 V/1 R or 6 V/1 R. The engine is water-cooled. Tyres: front 4.00-19 ASF, rear 8-32 AS. The fuel is diesel. Construction: unit construction (no separate frame). The linkage is category I. Around 8.652 units were built. The FARMALL D-LINIE series covers 3 models. Rated output within it ranges from 14 to 30 hp; the DED 3 sits in the lower part of that range with 20 hp. Its immediate neighbours are the DLD 2 below it with 14 hp and the DGD 4 above it with 30 hp. Unladen weight within it ranges from 820 to 1,730 kg; here the DED 3 sits in the middle of that range with 1,230 kg. 381 McCormick models across 40 series are on record.

McCormick Farmall D line – the DED 3, DGD 4 and DLD 2 models built at the Neuss plant with two- to four-cylinder diesel engines, 10.3 to 22.1 kW and 1.1 to 2.2 litres of displacement

The Farmall D line was launched in the 1950s at the International Harvester plant in Neuss on the Rhine and comprises the DED 3, DGD 4 and DLD 2 models. The designation follows a letter scheme from the IHC system: D stands for the diesel version, the second and third positions for build size and equipment, and the final digit for the cylinder count.

The register lists 3 versions with 10.3 to 22.1 kW (14 to 30 hp) from two- to four-cylinders of 1,088 to 2,178 cc displacement at rated speeds between 1,750 and 1,800 rpm. Maximum torque ranges from 58 to 123 Nm. Operating weight ranges from 820 to 1,730 kg, length from 2,461 to 2,834 mm, width from 1,540 to 1,630 mm and height from 1,550 to 1,585 mm. All three models run on diesel.

With the D line, International Harvester set up its post-war European diesel programme for small and medium-sized farms, built specifically for the European market at the Rhineland plant in Neuss rather than imported from the US. The span from two- to four-cylinders thereby covered different farm sizes within a single shared range.

On a used purchase of these historic diesel tractors, points to check include the condition of the injection pump and nozzles, the tightness of the radiator and water pump, wear on the clutch and gearbox, and corrosion on the chassis and sheet-metal parts. Spare parts for the D line are found through vintage dealers specialising in International Harvester.

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.
