ABSTRACT:
There is disclosed a tree harvesting apparatus which provides a helical spline for permitting movement of a harvesting head about a central vertical axis thereof. This provides enhanced manoeuverability of the head to prevent damage to saplings or other immature timber. A chain saw chain detensioning system is also disclosed. The system permits a quick removal of a saw chain from the chain saw without the use of tools therefore is more easily changed in an expedited manner.
