Ces différences s'expliquent par trois facteurs principaux : la conception de la machine, la technologie du moteur et les méthodes de travail de l'opérateur. Cette brochure couvre ces facteurs et fournit des informations de référence rapides sur ce sujet.

The objective of this study was to assess the potential for downsizing skidder requirements on soft ground through the use of high-flotation tires. The test was designed to compare the relative performance of a 90-kw skidder with conventional tires and chains to that of a 67-kw skidder equipped with high-flotation tires. The comparison criteria were short-and long-term productivity, fuel consumption, ground disturbance and operating costs. The trial was performed in the Abitibi region of Quebec under contract to the Ministère de l'Énergie et des ressources du Québec.
Fuel consumption differs among the different types of equipment.These differences can be explained by three main factors: the design of the machine, the engine technology, and the operator’s work methods. This pamphlet covers these factors and provides quick reference information on this topic.

This report describes a joint FERIC, MER study designed to assess the effect of wide tires in skidding and scarification work on both soft ground and steep slopes. Trials under these site conditions were conducted in the Abitibi-Temiscamingue and Saguenay-Lac St.Jean Regions of Quebec respectively, in 1984. The performance of wide tires was compared to that of conventional tires with chains on cable skidders of equal size. Comparison criteria were productivity, gradeability and stability on slopes, fuel consumption, ground disturbance and effect on advance regeneration during skidding; and productivity, gradeability and stability on slopes and subsequent plantability when pulling scarification equipment.
