Abstract
A tree harvesting machine compreses a tree supporting part (1) provided with a feeding device (2) for feeding a tree in its longitudinal directon, and a cross-cutting saw (5) for cutting the tree at selectedlocations, wherein said part (1) is supported by a boom assembly (6) or the like. At temoment of action of the cross-cutting saw (5), the tree.supporting part (1) is moved downwards, preferably automatically 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 (R) at the cutting point (K) and thereby tending to cleave the tree, is at least partly compensated for. The movement (F) is controleld on the basis of one or more varioables measured before themoment of cross-cutting. The movement is implemented by releasing pressurized medium by means of a valve for a short time from an actuator (7) driven by pressurized medium and supporting the load caused by the tree, wherein at least one of the following operating values of the valve is adjusted: the aperture, the duration of the aperture, and the closing rate of the aperture.
