A method of logging a tree includes the steps of cutting the tree part way through the trunk with a cut near the bottom thereof, leaving a connecting portion of the trunk connecting an upper portion of the trunk above the cut to a lower portion of the trunk below the cut. A helicopter above the tree is connected to a point near the top of the trunk. The helicopter is moved away from the tree, thereby brewing the connecting portion and allowing the upper portion of the tree to be carried away by the helicopter. The method utilizes a helicopter logging tool comprising a body having a connection for a lifting device. There is an elongated guide connected to the body by a hinge. The guide extends vertically downwards away from the body when the tool is connected only to the lifting device. There is a pooh on the body to one side of the guide for engaging an object. When tile pooh engages an object and the body is lifted by the lifting device, the body rotates and the guide rotates about the hinge so that the guide continues to extend vertically. There is also a jig apparatus for cutting the tree. There are two guide bars, at least one of which has a stop mechanism. Spikes allow the guide bars to be connected to the trunk of the tree in horizontal, parallel positions on opposite sides thereof. A chain saw mount is slidingly received on each of the guide bars. When a chain saw is placed on the chain saw mount and moved towards the trunk of the tree along the guide bars, the tree is cut to a position determined by the stop mechanism on the guide bars.
