Improving quality and productivity in forest machine work and timber harvesting chain

In the cut-to-length harvesting method, which is dominant in Scandinavia, a harvester and a forwarder work as a pair. The harvester fells and delimbs the trees and cuts them to logs such that the value of the wood is maximized. The forwarder then carries the logs to the roadside for further transportation. The working conditions of the machines are very demanding: in the forest the weather can change from one extreme to an other during one work shift. Seasonal changes and differences between the trees in different stands are also major factors affecting the performance and productivity of the machines. In the project new methods are studied for monitoring and improving the performance, usability and dependability of forest machines. Special emphasis is given to improving the man-machine co-operation between the operator and forest machines.
