The KESLA 25SH-II impulse harvester delivers its best performance when processing knotty trees, requiring high cutting power when the strength of roller-fed heads is not enough. Impulse feeding does not damage the surface of the tree, and is suitable for processing precious wood. The 25SH-II is equally well-suited to cutting straight trees and processing piles. Optimum tree diameter is 40 cm.

The combination of unique jaws and additional cutting blades provides extra strength for processing large trees and improves cutting efficiency. The proStroke partial impulse system facilitates processing of knotty trees. KESLA 25SH-II fits basic machines from 10 to 15 tons.
