An improved tree harvesting apparatus includes a felling assembly which is effective to grip and sever the trunk of a standing tree. The felling assembly then positions the tree in a delimber assembly which delimbs and tops the trunk of the tree. The delimbed tree trunk is deposited in a bunk or carrier. The felling assembly includes a felling head which is disposed on an articulated felling boom. The felling boom is pivotally mounted on a frame of a vehicle and includes a plurality of pivotally interconnected boom sections. All of the boom sections can be pivoted about a generally horizontal axis to tilt the felling head. An intermediate boom section is pivotal about a vertical axis to move the felling head sideways. An outer boom section is pivotal about a horizontal axis to raise and lower the felling head. If necessary, the outer boom section can be utilized to shove against the butt end of a delimbed tree trunk to position the tree trunk in the bunk.
