The Valmet 903/903-4 is a model in the 03er series. Production: 1979–1983. The engine delivers 94 hp (69.1 kW), has 4 cylinders, with a displacement of 4,397 cm³. Torque is 320 Nm. Rated speed is 2,200 rpm. The machine is 3,905 mm long, 1,972 mm wide and 2,499 mm high. The unladen weight is 3,650 kg. The wheelbase measures 2,330 mm. Ground clearance is 460 mm. Top speed is 30 km/h. Transmission: 16 V/4 R. The engine is water-cooled. Tyres: front 10.00-16 ASF (A: 13.6-28 AS), rear 18.4-34 AS. The fuel is diesel. The bore measures 108 mm. The stroke is 120 mm. The compression ratio is 16:1. Maximum torque is reached at 1,500 rpm. Construction: frame construction. Injection pressure is 200 bar. Rated output across the Valmet range ranges from 22 to 136 hp; the 903/903-4 sits in the upper part of that range with 94 hp. Its immediate neighbours are the 702 S (A) below it with 91 hp and the 8000 above it with 98 hp. Rated output across the Valmet range ranges from 16.2 to 100 kW; here the 903/903-4 sits in the upper part of that range with 69.1 kW. 414 Valmet models across 21 series are on record.

The Valmet 03 range – Finnish tractors from Suolahti: the 903/903-4 and 1103/1103-4, a four-cylinder 4,397 cm³ diesel, 69.1 to 78.7 kW

The 03 range is the generation that followed the 02 range from the Finnish maker Valmet of Suolahti and carries over its numbering logic: the digits order the size class, while an appended -4 marks the four-wheel-drive version of the same base model. The register lists the smaller 903/903-4 and the larger 1103/1103-4 here, both with a water-cooled four-cylinder diesel of the same displacement but a different power rating and rated speed.

The register lists 2 versions with 69.1 to 78.7 kW from four-cylinder engines of 4,397 cm³, torque of 320 to 370 Nm, unladen weights of 3,650 to 3,950 kg, lengths of 3,905 to 3,930 mm, widths of 1,972 to 1,980 mm, heights of 2,499 to 2,710 mm and rated speeds of 2,200 to 2,300 rpm.

In the 1970s and 1980s Valmet was among Scandinavia's leading tractor makers, supplying mainly Finnish and Swedish farming plus export markets in Northern and Eastern Europe; the 03 range, with the 903 and 1103, covered the mid to upper power segment for mixed arable and grassland farms, before the later merger with Sisu reshuffled the brand's model line-up.

On used examples, the condition of the injection pump and cooling system, the state of clutch, gearbox and PTO, and on the -4 versions also the condition of the front axle, propshafts and transfer case all count; spare parts run through today's Valtra service network and independent farm-machinery dealers.

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.
