The R series from MAN includes the 4R3. Production: 1961–1962. The engine delivers 45 hp (32.9 kW), has 4 cylinders, with a displacement of 2,560 cm³. Rated speed is 2,200 rpm. The machine is 3,300 mm long, 1,865 mm wide and 1,505 mm high. The unladen weight is 2,500 kg. The wheelbase measures 2,070 mm. Ground clearance is 400 mm. Top speed is 19.1 km/h. The engine is water-cooled. Tyres: front 6.50-20 AS, rear 13-30 AS. The fuel is diesel. Construction: semi-frame construction. The gearbox offers 8 forward gears. There are also 4 reverse gears. The linkage is category II. The PTO runs at 540/1000 rpm. Around 1445 units were built. The R series covers 6 models. Rated output within it ranges from 40 to 45 hp; the 4R3 sits at the top of that range with 45 hp. Its immediate neighbours are the 4R2 below it with 40 hp. Unladen weight within it ranges from 2,350 to 2,640 kg; here the 4R3 sits in the middle of that range with 2,500 kg. 5237 MAN models across 68 series are on record.

MAN R (Nuremberg) – diesel tractors of the four-wheel-drive pioneer before tractor production ended in 1962: 2R1 to 4R3, four-cylinder diesels of 2.6 to 3.9 litres, 40 to 45 hp, 2.35 to 2.64 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 R range is among the last series before tractor production ended, when MAN handed the business to Fendt in 1962. The 2R1 to 4R3 models all carry four-cylinder diesel engines, one of which the register lists as a MAN D 0024 M 220; the 1,865 mm width is identical across all six versions, pointing to a shared axle and chassis for the whole range.

The register lists 6 versions with 29.3 to 32.9 kW (40 to 45 hp) from four-cylinder diesels of 2,560 to 3,927 cm³ at 1,800 to 2,200 rpm, unladen weights from 2,350 to 2,640 kg, lengths from 3,300 to 3,620 mm, a width of 1,865 mm and heights from 1,505 to 1,930 mm; hydraulic lift capacity reaches up to 2,880 kg.

The R range served the Bavarian post-war reconstruction market, where MAN competed with Deutz, Hanomag, Eicher and Fendt for mid-size field tractors; 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 diesel engine with injection pump, 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.
