FIELD: forestry.
SUBSTANCE: invention relates to timber industry and can be used to separate a pack stacked trees during mass forest harvesting using skidder-processor machines. Method of crosscutting stacked trees implemented by a forest machine equipped with a manipulator with a harvesting head includes guiding jaws of the harvester head to a tree located in the pile, grabbing the tree, pulling the tree through the working members of the harvester head while bucking boughs and block cutting. Prior to grabbing a tree from the pile the tree is moved relative to other trees by a disconnector. Disconnector is installed on the handle of the manipulator in such a manner that there is free space between trees that are next to each other in the pile; said space is sufficient for free passage of the jaws of the harvester head that are able to grab a selected tree.
EFFECT: method increases efficiency of crosscutting of stacked trees using a harvester head.
