Again, we are turning our eyes towards a sturdy forwarder. This time it´s a Rottne F20 D that´s in focus. A loading capacity of 20 tons makes this machine one of the largest forwarders on the market.
Rottne Industri AB is a family-owned company located in the south of Sweden. All production of the Rottne machines happens within the Swedish borders. We, older loggers, will probably never forget their classic, the Blondin (the Blond). The Blondin was the base unit from 1968 to 1988, both for forwarders and harvesters, but also for dumpers. Rottne is, by the way, the town where the main office and factory is located.
Rottne F20 D
After the Blondin there has been Rottne Rapid and Solid, and nowadays just F and H, as in Forwarder and Harvester. In today’s range, there are six forwarders from 10 to 20 tons loading capacity. Read more about them here.
The top of the line is the F20D that we focus on in this article.
