There is disclosed a tree harvesting head assembly which provides an improved cutting means for permitting movement of a saw chain linearly outwardly from a first position behind a tree to be cut to a second position transversely forwardly of a tree to be cut. The cutting means in combination with the grapple means and engagement arms of the head assembly facilitates the harvesting of trees on rough terrain in an expedited and safe manner.
