Now available with the RK 50 crane and new control panels!
Available now with the new RK 50 that offers better geometrical features and greater performance compared to its predecessor. As a result, harvester production levels are largely increased in combination with new crane lever controls and press button functions.
The thinning harvester for all occations, and we mean all occations. The 2004 has in every detail been designed to be able to stand up for also extreme conditions. With great care and high precision the machine will run also where the terrain is tough.

High degree of use is the first demand. Not many machines get such warm welcome by the forestry owners as a 2004. Small outside measurement, low weight, the unique transmission, the flexible loader, the compact single-grip head will together give the possibilities for a healthy stand free of damages, also after thinning. Therefore forestry owners prefer a machine as 2004 when it is time for thinning.
