ABSTRACT:
A tree cutting and gripping head assembly for use in a tree felling apparatus which includes a single movement effecting unit, such as a hydraulic ram, connected both with respect to a tree cutting part and a tree gripping part of the head assembly for effecting movement for both of these parts through their respectively operative strokes in response to a single actuating movement of the unit. The head assembly also embodies a number of improved cutting blade constructions which are particularly useful in splitting the tree stump during cutting operation or otherwise forming pockets in the upper surface of the tree stump for retaining moisture which materially aids in the disintegration of the stump.
