Ponsse’s new feed roller solutions enhance the multi stemming EH25 energy wood harvester head

With PONSSE harvester heads, multi-stemming is performed with the control function of delimbing knives and feed rollers: the rollers hold the previous trunk in place while the knives grab a new one. After this the rollers open and close grabbing the new tree, and the new tree is cut. The operator can control all collecting features by the push of a button. Finally, the bundle is assembled as whole trees or it is delimbed by feeding the bundle through the harvester head, where necessary.

The size of the harvester head is chosen according to the size of the trees to be handled. A strong harvester head, equipped with a large opening, is naturally able to hold larger trunks better. When the diameter of the trunk is small, a smaller and lighter harvester head can be used. The forwarder should preferably be equipped with a load scale for production data recording.

PONSSE EH25
PONSSE EH25 energy wood harvester head is a simple, powerful tool especially for harvesting raw energy material during timber stand improvement felling. Thanks to its multi-stemming feature, guillotine cutting method and easy user controls, It is a profitable solution when no feeding and delimbing are necessary.

It is easy to manage the harvester head even in confined harvesting sites, because its centre of gravity is sufficiently far away from the boom tip. Thanks to the grapple’s powerful tilt feature, harvested bundles can be held in the vertical position, which facilitates work under difficult conditions, and prevents harvest damage to the residual tree stand. The tilt position can be controlled to any angle. PONSSE EH25 can be installed to different base machines. EH25 has excellent geometry so loading can also be performed easily and efficiently
