With the A 40, MAN offers a model from the A series. Production: 1956–1957. The engine delivers 40 hp (29.3 kW), has 4 cylinders, with a displacement of 3,473 cm³. Rated speed is 1,700 rpm. The machine is 3,135 mm long, 1,680 mm wide and 1,700 mm high. The unladen weight is 2,150 kg. The wheelbase measures 1,895 mm. Top speed is 28.3 km/h. Tyres: front 6.50-20, rear 10-28, 11-28, 11.25-24. The fuel is diesel. Construction: frameless unit construction. The gearbox offers 6 forward gears. There are also 1 reverse gears. Around 511 units were built. The A series covers 6 models. Rated output within it ranges from 25 to 42 hp; the A 40 sits at the top of that range with 40 hp. Its immediate neighbours are the A 32 H/A below it with 32 hp and the A 45 A above it with 42 hp. Unladen weight within it ranges from 1,890 to 3,090 kg; here the A 40 sits in the lower part of that range with 2,150 kg. 5237 MAN models across 68 series are on record.

MAN A (Nuremberg) – diesel tractors of the four-wheel-drive pioneer with H for the row-crop version: A 25 A to A 50, two- to four-cylinder diesels of 1.7 to 3.5 litres, 32 to 42 hp, 1.9 to 3.1 t

MAN built diesel tractors in Nuremberg from 1921 to 1962 and is counted among the pioneers of four-wheel drive in the tractor business; the A range is, alongside the R range, one of two programmes of the Nuremberg works before the tractor division was sold to Fendt in 1962. The type logic runs from the small A 25 A to the large A 50, with the A 32 H/A as row-crop version – H in German tractor nomenclature marks the narrow-track, higher-clearance variant for row-crop farming. The engines span two- to four-cylinder diesels, with one model listed in the register as a multi-fuel engine able to run on distillates besides diesel.

The register lists 6 versions with 23.4 to 30.7 kW (32 to 42 hp) from two- to four-cylinder engines of 1,736 to 3,473 cm³ at 1,500 to 2,000 rpm, unladen weights from 1,890 to 3,090 kg, lengths from 3,120 to 3,625 mm, widths from 1,580 to 1,970 mm and heights from 1,700 to 2,310 mm.

The A range, like the R range, served the Bavarian post-war reconstruction market, where MAN competed with Deutz, Hanomag, Eicher and Fendt for field tractors of various size classes; with the sale of the tractor division to Fendt in 1962, MAN's independent tractor manufacture in Nuremberg came to an end.

On used tractors, the MAN engine with injection pump or multi-fuel system, clutch and gearbox, hydraulics and linkage, brakes and sheet metal and frame for rust count; since the make has built no tractors for over six decades, parts now run only through specialists and collector markets.

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.
