Abstract
In November and December 1994, FERIC compared the lumber yield from two roughly 75-m3 furnishes of softwood harvested with two different systems. One furnish was harvested as full-trees using a feller-buncher, a cable skidder, and a stroke delimber. The other was harvested using a cut-to-length system comprising a single-grip harvester and forwarder. All the wood was scaled and milled separately at Domtar Inc.'s sawmill in Val d'Or, in Quebec's Abitibi region. The results were similar for both furnishes, though the cut-to-length system provided a slight benefit in terms of volume yields and the value recovery per cubic metre. Conversely, the average value of the products produced from full-trees was slightly higher. Losses after drying were nearly identical. However, the operational context may not have been perfectly typical, especially in the case of the full-tree system. Other studies would be necessary to confirm the wider applicability of the results in this report.
