A powerful new harvester head for processing eucalyptus trees is in the market. Finnish powerhouse Ponsse has released a new debarking head, the H8HD Euca harvester head, for eucalyptus sites.

The new powerful harvester head has been designed as a response to customer needs, and it further strengthens Ponsse’s strategy to be the leading global manufacturer of harvester heads.

The new harvester head has been designed for the Ponsse Bear harvester, but it is the “ideal” solution for track-based machines. The H8HD Euca is an effective tool in forests where the diameter of eucalyptus stems can be up to 50 cm. The geometry of the new harvester head’s debarking knives and feed rollers improves the efficiency of H8HD Euca in debarking and processing both smaller and larger stems.

Ponsse’s heavy-duty frame structure means that the new harvester head can withstand the extreme loads of track-based machines, according to Janne Loponen, Harvester Heads Product Manager.

The H8HD has been optimised to debark trees. Its feed rollers and debarking knives guarantee first-rate debarking results from start to finish. The solid and robust tilt frame give the harvester head the durability needed in debarking. Automated functions control saw movements according to the tree diameter and saw-bar position and allow trees to be cut quickly.

All Ponsse harvester heads have been designed to withstand the toughest conditions. They are characterised by a simple and solid structure, which enables them to be used in various harvesting applications, ranging from harvesters to track-based solutions.

All Ponsse harvester heads are manufactured and designed at the Ponsse factory in Vierema. The design process is comprehensive and covers, in addition to mechanical parts, the electronic control system, controls and software.

The manufacturing process is highly automated to ensure high quality and measuring accuracy. Durable hoses and delimbing knives form an important part of and covers, in addition to mechanical parts, the electronic control system, controls and software.
