In 1955, Ködel & Böhmin's smaller threshing combine, the Köla Combi, was introduced to the market. It was equipped with a 34-horsepower Mercedes diesel engine. The engine was located next to the driver on the right-hand side. The cutting width was 190 cm. The height adjustment of the unloading reel was mechanically standard. The threshing drum width was 70 cm, and it had three rasp bars. In the tank version, the tank was positioned below the sack-loading platform, and the discharge pipe was at the rear of the combine, where the grain was conveyed by a horizontal auger located under the belly of the combine. In 1959, the Combi Special was introduced, featuring a 205 cm cutting table. The Combi Extra, on the other hand, was equipped with a 190 cm cutting table but had a wider front axle and larger wheels than the original Combi. Over the years, the Combis underwent quite a few upgrades, including an increase in engine power to 38 horsepower.

Also introduced in 1959 was the larger Favorit, which had a cutting width of 255 or 300 cm. Its construction was similar to the Combi, meaning it was very low-profile. However, its height was increased by 63 cm due to a high-rise grain elevator. A novelty was the Vario-System, which allowed the tank to be easily folded away when desired, directing the grain into sacks. The Favorit's threshing drum was not only wider but also had a larger diameter (56 cm). The Fordson engine initially offered 55 hp, later increased to 68 hp. Additionally, 56-horsepower Deutz or Hanomag diesels were available.

Köla machines were imported to Finland during the years 1960-66 and 1967-69.
