ABSTRACT:
A tree harvesting machine is disclosed which is of the type having a wheel-mounted frame, a tree harvesting mechanism at the front and a berth at the rear for accumulated felled trees. An inverted tree grapple is provided forwardly of the berth and is mounted to the berth so that it can be slid to and from the berth whereby the grapple may be held close to the berth during accumulation of felled trees and moved away from the berth when loaded. In this last position, the center of gravity of the load has thus been shifted forwardly. The berth itself is pivoted to the frame to allow loading to take place in rearwardly inclined position. Once loaded, the berth may then be uprighted easily since the center of gravity of the load has shifted forwardly.
