Processing:
Once the tree is extracted to the landing, it must be processed
before loading out onto the truck. This typically involves
taking the branches off (delimbing), topping the tree, and
then cutting the stem into logs (‘bucking’)
according to a certain set of mill specifications. These
tasks can be carried out by chainsaw, but in the south this
is typically done with a loader that has a pull-trough delimber,
or a number of different machines. It is also possible to
process the trees ‘at the stump’ and this is
typically referred to as a cut-to-length system. If the
end use of the majority of the wood is for pulp and paper,
the wood may be chipped on site, called an in-woods chipper.
To remove the landing residues, either for disposal back
on site or for the production of hog-fuel, a grinder can
be used.
