In Finland harvesting work is almost always done mechanical with harvester, but the same work can be carried out by a lumberjack and a chainsaw, called manual harvesting. Harvester is a machine operated by one person. It is used to fell, de-branch, cut in preferred lenghts and to measure the volume of the trees. In both mechanized and manual harvesting, the forest tractor in its turn transports the logs to the intermediate storage site, most commonly a wood pile beside the nearest logging road. The combination of harvester and forest tractors is called the harvesting chain.
