Productivity and Costs of Forest Machine Systems in the Harvesting of Over-Grown Willow Plantations

F. Di Fulvio, D. Bergström, K. Kons & T. Nordfjell
The modified forage harvesters used for harvesting operations in conventional Short Rotation Willow Coppice (SRWC) in Sweden suffer from their inability to harvest stems whose thickness at stump height exceeds 60­70 mm. A valuable alternative method might be to use forest machines fitted with Accumulating Felling Heads (AFH), which were developed for harvesting small diameter trees. A field study was performed in a 6 year old SRWC. Two areas with different growing conditions were identified...
