Valmet – other models: the collective page of the Finnish and Brazilian tractors outside the named ranges, from the Valmet 15 and 20 of the 1950s through the 361 D, 502 and 705 to the Brazilian 65, 85 and 118 Alcool and the 6000s, 11 to 140 kW, Valmet, Sisu and MWM engines
This page gathers the Valmet tractors the register could not assign to a named range – the Finnish state group Valtion Metallitehtaat that built Finland's first tractor in 1951 in Tourula near Jyväskylä with the Valmet 15, moved tractor production to Suolahti in 1969 and in 1960 founded a second tractor plant in Mogi das Cruzes near São Paulo, which still produces today as Valtra do Brasil. The type logic: the early models 15, 20 and 33 give the hp class, the three-digit 359, 361, 502, 565, 702 and 705 of the 1960s and 1970s the size in the first digit and the generation in the following ones, D the diesel, -4 four-wheel drive; the Brazilian 65, 85, 118 and 148 give the hp class, and the 118 Alcool is a tractor with ethanol engine from the Brazilian alcohol programme of the 1980s – noted in the register as fuel Alcohol. The engines are Valmet's own from Linnavuori, in Brazil MWM diesels built under licence; in 1997 the name passed to Valtra with the sale to Sisu.

Valmet was the tractor of Finnish farming and forestry and is still one of the big brands in Brazil today; the 6000s and 8000s of the 1990s laid the foundation for Valtra's success in Western Europe.
On used tractors, originality and engine condition count on the classics, clutch, gearbox and hydraulics on the 500s and 700s, HiShift shuttle and electronics on the 6000s; parts run through Valtra and AGCO, in Brazil through Valtra do Brasil.
