In previous articles we have written about two of the big harvesters in the forest; The Rottne H21 and the Komatsu 951. Now, the time has come to present another giant in the woods – the Ponsse Bear.

Ponsse

The Ponsse company has been around for 50 years now which makes them one of the younger forest machine manufacturers. Nevertheless, nowadays they are one of the largest manufacturers of CTL machinery in the World.

Ponsse is a family business that has a reputation of going their own path. As for an example, they have never had the older type of harvester, two-grip harvester, in their range. They went straight for today’s crane mounted harvester heads.

We visited the contractor Niklas Savilahti on a nice clear-cut site where he was operating his Ponsse Bear. In his early career, as an employee, he was operating also other brands, but since he started his own business, he has stuck to one brand – Ponsse. This is his sixth Ponsse (third Bear) since he started the company in 2005.

Ponsse has seven harvesters in their range today, and seven forwarders. They also have a range of eleven harvester heads, and a dual machine (combined harvester and forwarder).
