In our series about big harvesters we have reached the EcoLog 590F. It was a short visit, due to bad planning from my side, but man – that machine produced some cubic meters quickly! See for yourself in the film here below …

We have written a lot about the North Swedish machine manufacturer EcoLog this year. The reason is that they have been very active in presenting new models. Also, they merged with Gremo which meant that the product range became even wider. There are a number of articles about that here at Forestry.com. One of them you can read here.
