3D simulation of forestry machines facilitates training that is efficient and free from danger, e.g. for the purposes of the education and training of prospective forestry machine operators. With realistic simulation and seamless integration of the necessary hardware control unit the trainee can be instructed in all aspects of workflow which occur in the operation of a real-life machine. This can range from crane movement, to vehicle steering, to operating the on-board computer system. At the same time, the forestry machines simulator can serve as an ideal marketing and innovation tool. Extending beyond this, the complete simulation of the workflow in the forest, from tree felling with the forestry harvester, to log carrying with the forwarder, through to removal by the timber transporter, encourages a comprehensive understanding of how the processes are interrelated.
