Valmet 15-20

The project to develop a tractor, started by Valmet in the late 1940s, was completed in 1952, when the first series of 75 Valmets was produced. The four-stroke carburetor engine used petrol as fuel. The 1.4-liter engine had a power output of 15 hp. There were three gears forward and one backward. The lifting device operated mechanically with a long lever. Valmet tractors were sold by three central cooperatives: Hankkija, Kesko, and OTK. Suitable implements for the small tractor were developed together with domestic work machine manufacturers. Officially, the tractor was simply called Valmet, but later the model designation Valmet 15 was used.

In 1955, an improved version, the Valmet 20, was introduced, which featured a hydraulic lifting device as an optional accessory. Engine power was increased to 22 hp for the petrol version and 19.5 hp for the petrolene version. The front axle was replaced with an angular, beam-structured one. In total, about 9,800 of the small Valmets were produced.
