The C series from MAN includes the C 40. Production: 9/1955–1957. The engine delivers 40 hp (29.3 kW), has 4 cylinders, with a displacement of 3,185 cm³. Rated speed is 1,800 rpm. The machine is 3,135 mm long, 1,680 mm wide and 1,700 mm high. The unladen weight is 2,100 kg. The wheelbase measures 1,825 mm. Ground clearance is 400 mm. Top speed is 28.3 km/h. The tank holds 42 litres. The engine is water-cooled. Tyres: front 6.50-20, rear 10-28, 11-28, 11.25-24. The fuel is diesel. The bore measures 96 mm. The stroke is 110 mm. Construction: frameless unit construction. The gearbox offers 6 forward gears. There are also 1 reverse gears. Injection pressure is 200 bar. Around 1687 units were built. Rated output across the MAN range ranges from 13 to 60 hp; the C 40 sits in the middle of that range with 40 hp. Its immediate neighbours are the 2P1 below it with 35 hp and the AS 542 above it with 42 hp.

MAN C – four-cylinder agricultural diesels from Nuremberg in the 1950s: C 40 with 3,180 to 3,185 cm³, 29.3 kW (40 hp), tractor production ended 1962

MAN's agricultural diesels from Nuremberg in the 1950s formed a stronger, four-cylinder class alongside the light two-cylinder series; the C series with the C 40 type belongs to this heavier group. MAN carried its own diesel-injection technology over from truck and engine production into the tractor, before the company finally halted farm-tractor manufacture in 1962.

The register lists 2 versions here with an output of 29.3 kW (40 hp) from the four-cylinder diesel engine of 3,180 to 3,185 cm³ displacement, at 1,800 revolutions per minute. Kerb weights range from 2,100 to 2,150 kg, at a length of 3,135 mm, widths from 1,580 to 1,680 mm and heights from 1,700 to 2,310 mm.

With the C 40, MAN positioned itself in the mid-power class of West Germany's post-war agriculture, a market already dominated at the time by established makers such as Fendt, Deutz and Eicher. The short production run and the end of MAN's tractor manufacture in 1962 make the C 40 a rare survivor of these transitional years.

When buying used, the injection pump, cooling system and clutch of the four-cylinder deserve particular attention, as do the frame and front-axle bearings after decades of service. As MAN no longer stocks tractor parts, buyers depend on holdings at vintage workshops and on adapting identical MAN engine components.

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.
