摘要
A method and apparatus for use in tree felling for causing a tree to tip under the influence of a force acting on the cutting surfaces of a saw notch in the tree trunk. The tipping force is produced by means of an inflatable cushion which is inserted in a flattened state into the saw notch and connected to the combustion chamber of the cylinder of the power saw motor to be inflated with compressed gas from said combustion chamber.
