The stroke is 114 mm. The compression ratio is 17:1. Maximum torque is reached at 1,445 rpm. Construction: unit construction (no separate frame). The 05 er-Baureihe series covers 3 models. Rated output within it ranges from 49 to 61 hp; the 305 (305/4) sits in the lower part of that range with 53 hp. Its immediate neighbours are the 205/205-4 below it with 49 hp and the 405 (405/4) above it with 61 hp. 414 Valmet models across 21 series are on record.

Valmet 05 range: collective page of Finnish tractors 205, 305 and 405 from Suolahti, three-cylinder 2,686 cm³ diesels, 36 to 45 kW

The 05 range from Valmet, with the models 205, 305 and 405, was built at the Finnish plant in Suolahti; the model numbers rank the three versions by power class, and the -4 suffix denotes the four-wheel-drive variant in each case. Unlike Valmet's larger ranges, the 05 range was deliberately kept technically simple, favouring robustness over added complexity. That simplicity became a selling point in the field. Valmet was the name of the Finnish farm-machinery works in Suolahti until the tractor division was renamed Valtra in the 1990s.

The register lists 3 versions with 36 to 44.9 kW from three-cylinder diesel engines of 2,686 cm³, an unladen weight of 2,710 kg, a length of 3,710 mm, widths of 1,745 to 1,950 mm and heights of 2,560 to 2,615 mm; torque ranges from 175 to 202 Nm at a rated speed of 2,350 rpm.

Tractors in this power class were popular all-round machines on Finnish and Scandinavian farms, suited to the shorter growing season of the north, and competed with comparable ranges from Volvo BM and Nordic import brands.

When buying used, condition of the three-cylinder diesel including cooling and injection, the gearbox and clutch, and on four-wheel-drive versions the front axle bearings all matter; spare parts are available through today's Valtra network and independent farm-machinery dealers in Scandinavia.

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.
