Abstract
The Forest Engineering Research Institute of Canada (FERIC) examined the level of butt damage from felling with a high-speed circular-saw felling head when a feller-buncher accumulated from one to five trees per cycle. The machine's productivity for the different number of trees per cycle was recorded, and the impact of factors such as terrain and stand conditions on wood damage is discussed.

Abstract
In stands with small stems (<0.10 m³/stem), the two-machine cut-to-length harvesting system (a single-grip harvester paired with a forwarder) generally has low productivity. In this situation, a multi-stem head should be used to improve the system’s productivity. However, at high densities (>1800 stem/ha), even multi-stem heads may not be enough to make the two-machine system viable. This report identifies the conditions under which a three-machine system (a feller-buncher teamed with an at-the-stump processor and a forwarder) would be viable based on the results of four recent studies as well as on data from past FERIC studies. The report also discusses the productivity of processor operators as a function of their number of years of experience.

Abstract
The Forest Engineering Research Institute of Canada (FERIC) monitored and evaluated an enhanced bucking trial. The recovery of veneer bolts, stud sawlogs, pulpwood, and hog fuel manufactured from measured short logs were compared to those revcovered from enhance-bucked long logs. This report also presents productivity and cost information.

Abstract
L'Institut canadien de recherches en génie forestier (FERIC) a examiné le niveau de dommages au gros bout des tiges dus à l'abattage par scie circulaire à haute vitesse, quand une abatteuse-groupeuse accumule de un à cinq arbres par cycle. La productivité de la machine a été enregistrée pour les différents nombres d'arbres par cycle, et l'influence de facteurs tels que les conditions de terrain et de peuplement sur les dommages causés au bois fait l'objet de discussion.

Abstract
With the increasing number of products that must be separated in the forest, it’s becoming increasingly important to carefully evaluate the impact of sorting on the productivity of forestry machines. As well, the assortment of log products is becoming increasingly diverse, with log lengths ranging from 2.5 m (8 ft) to 7.3 m (24 ft). This report summarizes the results obtained thus far by FERIC in terms of the impact of log lengths and of the number of products to separate on the productivity of cut-to-length harvesting machines. We developed a productivity model for single-grip harvesters as a function of mean stem volume (m³), the number of products to separate, the use of multi-stem processing, and the mean log length, and another model for forwarders as a function of the payload per trip, the travel speed, the number of products to separate, the mean log length, and the extraction trail length. A cost analysis is also presented that demonstrates, among other things, that the production of short logs has a significant negative impact on costs.

Abstract
Avec l’augmentation du nombre de produits à séparer en forêt, il devient de plus en plus important de bien évaluer l’incidence du triage sur la productivité des machines forestières. De même, le panier de produits "billes" devient de plus en plus diversifié, avec des longueurs de billes variant de 2,5 m (8 pieds) à 7,3 m (24 pieds). Le présent rapport se veut une synthèse des résultats obtenus jusqu’à maintenant par FERIC quant à l’impact des longueurs de billes et du nombre de produits à séparer sur la productivité des machines du procédé par bois tronçonnés. Un modèle de productivité a été établi pour l’abatteuse-façonneuse (en fonction du volume moyen par tige (m³), le nombre de produits à séparer, le façonnage multi-tiges et la longueur moyenne des billes) et pour le porteur (en fonction de la charge par voyage, la vitesse de déplacement, le nombre de produits séparés, la longueur moyenne des billes et la longueur du sentier). Une analyse de coût est également présentée, démontrant entre autres que la production de billes courtes a un très fort impact sur les coûts.
