The current state of the timber industry complex and the prospects for its further development indicate the need to revise the approach to organizing logging process as a resource-saving, economically and environmentally sound process. Rational nature management and careful use of available forest resources come to the fore. Today, logging machines are an integral part of logging, and technical condition of the equipment of these machines has a direct impact on their productivity, quality of round timber and amount of sawmill waste received. The paper presents a design solution that makes it possible to increase efficiency of forest machines in freezing temperatures, which increases their productivity and the quality of the resulting roundwood by reducing the generated logging waste.
