Log Max E6

The Log Max E6 head is the result of team work and Log Max experience. This head has been developed to meet the demands of eucalyptus harvesting using five delimbing knives to debark the log.


Log Max E6 is a brand new head specially developed for Eucalyptus harvesting.


With angled feed rollers arms the debarking process on Log Max E6 gets optimized. The frame has an idle support roller in its center to minimize friction. In the bottom part of the frame a fixed delimbing knife has been welded in. This knife has a contour optimized for Ø20 - 260mm (0.8’’- 10.24’’) trees. Diameter measuring is available as an optional equipment.

The Log Max patented knife control system increases productivity by minimizing feed friction. The unique compound curve delimbing knife profile provides outstanding stem coverage and increased log quality.

The new Log Max E6 is built with well tested components used in Log Max’s other harvesting heads. This makes sure that the Log Max E6 holds the same excellent quality and productivity as all other Log Max products.
