Theoretical and experimental studies to substantiate the choice of a manipulator for a harvester are presented. A mathematical model of the harvester's operation has been developed based on natural and production-technological factors, as well as the characteristics of the machine base and the harvester head. The characteristics of the manipulator have been substantiated, in particular, the maximum reach and load moment of the manipulator for the given parameters of the base machine and the selected harvester head. When choosing a manipulator, it is recommended to proceed from the fact that some part of large trees can be left in the cutting area or dumped with chainsaws. It has been established that the manipulator boom reach within the range from 8 to 11 m has little effect on the volume and number of harvested trees. The percentage of the harvested volume of wood depends little on the boom reach of the manipulator and remains at least 90 %.
