Abstract
All-terrain vehicles (ATV's) can be used successfully to accomplish certain tacks in woodlot operations. These tasks include chemical spraying, hauling seedlings and wood products, transporting small equipment and providing transportation for the driver. ATV's are versatile, mobile, easy to transport and can travel on very soft ground. They require a special driving technique. The safety of ATV's is discussed in relation to the driver`s technique and to the ATV's handling limits which can be exceeds in certain operating conditions.

Abstract
Dans le but de permettre à l'industrie de mieux saisir la relation entre le déplacement hors-route d'une machine et le confort de l'opérateur, FERIC a évalué les niveaux de vibrations dûs au transport, générés par des débusqueurs à roues dans diverses conditions de fonctionnement. Ces vibrations ont été mesurées pour un échantillon de débusqueurs à pince et à câble, dotés de sièges à suspension et de sièges rigides, durant des opérations réelles en Ontario et au Québec. Les vibrations globales du corps enregistrées ont été analysées en termes de valeur efficace, de valeur crète et de facteur de crète. Les résultats ont montré que les opérateurs étaient dans tous les cas exposés à une vibration quotidienne égale ou supérieure aux limites "acceptables" reconnandées par la norme 2631 de l'ISO.

Abstract
To further the industry's understanding of the relationship between off-road travel and machine operator well-being, FERIC evaluated the motion induced vibration levels generated by wheeled skidders working in a variety of operating conditions. Ride-induced vibration was measured for a sample of grapple and cable skidders, both with and without suspension seats, during actual operations in Ontario and Quebec. The whole-body vibration (WBV) recorded was analysed in terms of RMS, peak, and crest factor levels. The operator's daily vibration exposure was found to equal or exceed the "acceptable" limits as defined by the ISO 2631 standard in all cases. In addition, the report presents a discussion of WBV theory and issues of potential interest.

Abstract
Air-conditioning systems on Canadian logging operations have traditionally suffered form low reliability, as is reported in a survey of FERIC's member companies. This report is intended to provide an overview of the current situation, and to assist present and future users by informing them about air-conditioning principles, maintenance requirements, choice of components, and the use of these components in actual applications. With judicious choice, installation and care, such systems can be successfully applied in the forest industry.

Abstract
Weldwood of Canada Limited's William Lake Operations and the B.C. Ministry of Forests and Lands, Cariboo Forest Region, agreed to a field trial on two sites (CP 122 and CP 140) to determine whether small crawler tractors could log steep slopes in the Central interior and satisfy economic and environmental constraints. FERIC monitored the logging trials, measuring log production and soil disturbance for small crawler-tractor and cable-yarding systems from June 1984 to march 1985. For additional comparison, a rubber-tired-skidder operation was also monitored for a six-week period in the summer.

Abstract
Les systèmes de climatisation de l'air utilisés dans les exploitations forestières canadiennes ont traditionnellement fait preuve de peu de fiabilité, comme le rapporte une enquête auprès des compagnies-membres. Le présent rapport vise à donner un aperçu de la situation actuelle, et à aider les utilisateurs présents et futurs en les renseignant sur les principes de la climatisation, l'entretien requis, le choix des composantes, et l'usage de ces composantes dans les applications actuelles. Ces systèes pourraient être utilisés avec succès dans l'industrie forestière, moyennant un choix judicieux ainsi qu'une installation et des soins appropriés.

Abstract
A prototype rock separator designed to separate rocks greater than 2.5 cm was built and tested at Nicholson Murdie Machines Limited's operation. The prototype demonstrated that a rubber-belted conveyor can be used to separate rocks from woody material when operated with a side tilt and a speed and slope that are greater than normally used to transport wood waste. Rock separation rates greater than 90% with wood loss of 29% were achieved during the field tests. Average production rates of 8.8 tonnes per hour were achieved during prototype testing.

Abstract
The objective of this study was to compare grapple yarding feller-director bunched wood with feller-director unbunched wood. The study was done at Weyerhaeuser Forest Products Company's vail operations, near Olympia, Washington. FERIC monitored a Washington 108 grapple yarder in three areas over a period of 16 days. Costs in the three areas ranged from a low of $1.65/m**3 to a high of $3.11 m**3. The bunched-wood area produced 10% more trees per productive machine hour and 36% more trees per turn than the adjacent unbunched area.
