The Valmet 604-4 is a tractor belonging to the group of agricultural tractors, manufactured in 1985. As a representative of the Valmet/Valtra brand, this model is positioned in a specific power range for field operations. The design is based on a three-cylinder engine with a displacement of 3,290 cm³, which provides a rated power of 45 kW. This technical foundation forms the basis for its operational capabilities in daily use on arable land and grassland.
The available power of 45 kW enables the towing of medium-sized implements, with power transmission occurring via a six-speed gearbox. This number of gears requires careful selection of driving speed to achieve the optimal engine speed for the respective soil cultivation task. The unladen weight of 2,990 kg ensures sufficient traction, while the gross vehicle weight rating of 6,580 kg defines the maximum load capacity for implements and ballast weights. The dimensions, with a length of 3,750 mm and a width of 1,940 mm, determine maneuverability on narrow paths and compatibility with existing shed structures.
Within the model series, the 604-4 occupies a defined position determined by its specified technical parameters. The combination of specific displacement and power class clearly places the model in the segment of light to medium-duty tractors. The six available gears form the core of the gear stages, a factor that must be considered when planning work processes on uneven terrain. The ratio of unladen weight to gross vehicle weight rating provides flexibility for adaptation to different soil conditions and implements without exceeding the structural limits of the chassis.
Valmet-Valtra – other models: the Finnish tractors outside the named ranges, from the 600 and 800 class to the 8000 series, 45 to 118 kW, three- to six-cylinder, four-wheel-drive suffix "-4"
This page gathers the Valmet and Valtra tractors the register could not assign to a named range – from the 600, 800 and 900 generation of the 1970s and 1980s to the 6000 and 8000 series of the 1990s. Valmet began building tractors in 1951 in Linnavuori, Finland; from the 1960s some export models carried the Valtra name, and in 1997 the tractor divisions of Valmet and the Finnish engine maker Sisu merged into the new Valtra Oy, part of AGCO since 2004. The type logic is simple: the base number orders class and model year, the "-4" suffix marks four-wheel drive (nelivetoinen), and Hitech denotes a higher equipment level. The engines come from Sisu Diesel of Nokia, Finland, later AGCO Power.

The register lists here 18 versions with 45 to 118 kW from three- to six-cylinders of 3,290 to 7,400 cm³, unladen weights from 2,990 to 5,240 kg, gross vehicle weights from 6,500 to 11,000 kg, lengths from 3,750 to 5,900 mm and widths from 1,940 to 2,500 mm.
Valmet and Valtra stand for rugged, cold-resistant tractors from the far north; the brand is deeply rooted in Finland, Scandinavia and the Baltic states, and a second plant in Brazil also supplies South America. In the mid and upper power segment it competes with John Deere, Case IH and Massey Ferguson, and is regarded as a simple-to-maintain alternative with durable mechanics.
On used examples of these model years, look for rust on wings and cab floor from road salt, the condition of the hydraulic pump, PTO and clutch, hours on the Sisu engine and, on four-wheel-drive models, wear on the front axle and transfer case; parts run through the Valtra/AGCO dealer network.

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.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
