The article presents theoretical and experimental studies for choosing a manipulator for a harvester taking into account of natural and technological aspects of sustainable development of the forest complex. A mathematical model of the harvester operation is developed based on natural and technological factors, as well as the characteristics of the machine base and the harvester head. Experimental results allow us to determine the rational characteristics of the manipulator for Siberia region of Russia, in particular, the permissible overturn and load moments of the manipulator for the specified characteristics of the base machine and the selected harvesting head. The maximum outreach of the manipulator’s boom in the range from 8000 to 11000 mm has little effect on the volume and number of harvested trees. The percentage of harvested wood volume almost does not depend on the maximum manipulator boom outreach and remains within at least 85%.
