One option which can only be executed by a
special machine is the “harwarding” of short logs.
In this case a special machine, the harwarder, fells
the tree, delimbs it, cross-cuts it into logs and skids the logs to the forest
road (buffer 10 to 33). All these sub-processes are done in one step without a
buffer to interrupt.
Since all the sub-processes are done by the
harwarder, it is assigned to the mechanized work.
