More machines from model year 1952

The BMD comes from International Harvester. Production: 1952–1953. The engine delivers 40.5 hp (29.8 kW), has 4 cylinders, with a displacement of 4,326 cm³. Rated speed is 1,450 rpm. The machine is 3,226 mm long, 2,159 mm wide and 1,989 mm high. The unladen weight is 2,386 kg. The wheelbase measures 2,390 mm. Ground clearance is 521 mm. Top speed is 26 km/h. Transmission: 5 V/1 R. The engine is water-cooled. Tyres: front 6.50-16, rear 12-38. The fuel is diesel. The bore measures 101.6 mm. The stroke is 133.35 mm. The compression ratio is 16.8:1. Construction: semi-frame construction. Around 927 units were built. Rated output across the International Harvester range ranges from 13.4 to 335 hp; the BMD sits at the bottom of that range with 40.5 hp. Its immediate neighbours are the FARMALL 340 below it with 40 hp and the 350 UTILITY above it with 41 hp. Rated output across the International Harvester range ranges from 9.9 to 246.4 kW; here the BMD sits at the bottom of that range with 29.8 kW. 391 International Harvester models across 45 series are on record.

International Harvester – other models: the collective page of tractors outside the named ranges, from the 10-20 and 15-30 of the 1920s through the 404, 606 and 706 to the 1066 Hydro, 1456, 4186 and 7488, 11 to 235 kW

This page gathers the International Harvester tractors the register could not assign to a named range – the Chicago brand that emerged in 1902 from McCormick and Deering, invented the row-crop tractor with the Farmall in 1924 and was the world's largest tractor maker into the 1960s before being absorbed into Case IH in 1985. The type logic changed over six decades: the early 10-20 and 15-30 types give drawbar and belt power in hp; the 04 series of the 1960s (404, 504, 606, 706, 806, 1206) orders the size in the first digit and carries with the 1206 the brand's first turbodiesel; the 56 (656, 856, 1056, 1256, 1456), 66 (1066, 1466) and 86 series of the 1970s follow the same logic with Hydro as stepless hydrostatic transmission; the articulated 4100 to 4186 and 7288 to 7488 (2+2) are the big tractors; the industrial versions carry the suffix Industrial. The engines come from IH's own plants in Chicago (Melrose Park), Neuss and Doncaster, as petrol, LPG and diesel versions; Nissan and Mitsubishi engines sit in the Japanese compact tractors of the 1980s.

The register lists here 179 versions with 11 to 235 kW from one- to eight-cylinders of 2,209 to 13,387 cm³, PTO outputs from 15 to 95 hp on the recorded models, unladen weights from 1,308 to 27,600 kg, lengths from 2,388 to 6,528 mm, widths from 1,310 to 2,832 mm and heights from 1,397 to 3,550 mm.

IH tractors are North America's most-collected after John Deere; the 06, 56 and 66 series are regarded as the tractors that motorised American arable farming of the 1960s and 1970s.

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.
