10 years after the introduction of the Nisula N-series harvester, a total makeover has been done to further meet the requirements in thinning operations. The target has been to come up with a specialized harvester for thinning, as a complement to traditional harvesters. Ground pressure, ergonomics, and simplicity are key issues. 
The Nisula N6 harvester
The new harvester by Nisula has a completely redesigned, simple frame structure. Strong chassis and high ground clearance gives an efficient mobility also under though terrain conditions. The rigidity in the frame gives good stability and no wheel ballast is required.

The cabin is quiet which according to Nisula improves the productivity of the operator. Large windows give good visibility around the machine and up toward the treetops.
