Abstract
In a control method of a tree harvesting machine, the tree harvesting machine comprises a tree-supporting part (,) with a feeding means (,) for feeding the tree in its longitudinal direction and a cross-cutting saw (,) for cutting the tree at selected locations. The part (,) is supported by a boom assembly (,) or the like. At the moment of action of the cross-cutting saw (,), the tree-supporting part (,) is moved by means of the control automatics of the tree harvesting machine in such a way that the force caused by the weight of the tree, tending to bend the tree at the cutting point and thereby tending to cleave the tree, is compensated at least partly.
