The multi-stemming function of harvester heads is a solution for the productive harvesting of partially-delimbed or undelimbed pulpwood and energy wood.

We have a broad selection of alternatives: all modern PONSSE harvester heads in the various size categories are suitable for multi-stemming either as such or equipped with minor accessories.



With multi-stemming feature you can harvest both industrial and energy wood simultaneously, which increases the yield. All modern PONSSE harvester heads can be used for multi-stemming even without mechanical changes. When the aim is to harvest delimbed wood from the stand with multi-stemming, the handling and feeding of bundles can be improved with new feed roller solutions. The solution also works well in regular industrial wood felling.

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.
