PONSSE OYJ PRESS RELEASE 10 October 2007 AT 14.00 Ponsse developing a harvesting solution for soft peat soil Ponsse has been involved in the development of wood harvesting technology for soft peat soil together with the Finnish state forest enterprise Metsähallitus and the Finnish Forest Research Institute. During the course of the project, a new prototype has been developed enabling profitable and environmentally friendly harvesting also on soil with bad bearing capacity. The concept is based on a ten-wheel, five-shaft forest machine equipped with a soft ground track solution, which in combination significantly decrease the surface pressure imposed on the soil compared with traditional solutions. ”The increased need for timber harvesting on soil with bad bearing capacity has been recognised at Ponsse. The quantity of timber harvested from peat soil, trenched areas and young thinning forests has been steadily increasing. In Finland, the annual need for added harvesting capacity amounts to approximately 10-15 million cubic metres. Changing climate conditions also impose new requirements on harvesting machinery, as warm winters make the harvesting season shorter. The starting point of the newly designed concept has been to develop a harvesting solution suitable for soft peat soil and to extend the harvesting season for existing harvesting machinery while simultaneously observing the environmental requirements. The results of the research are very promising and anticipate improvements in terms of contractors' finances and environmental values alike,” says Hannu Airavaara, Director (Renewable Energy Solutions) of Ponsse Oyj.
