ABSTRACT:
A mobile harvester which is capable of severing trees at their base, one at a time, and gathering trees, one at a time, while the previously accumulated trees are rigidly held together. The harvester has tree gathering means located vertically above a shear blade mechanism and this gathering means includes two pairs of power operated arms which are pivotally mounted so that each pair of arms can be individually and selectively swung between an open, tree receiving position and a closed, tree holding position. One of the pairs of arms holds the accumulated trees while the other pairs of arms gathers subsequently severed trees, one at a time, and brings them into the bundle of previously accumulated trees. Each of the arms of one of the pairs of arms is formed as an inner part pivotally mounted on a support frame and an outer part pivotally mounted intermediate its length to the inner part so that when the pair of arms is shifted to its open position after functioning to hold accumulated trees, the outer parts of the arms can pivot on their inner parts and be withdrawn in generally opposite lateral directions and out from between the accumulated trees and a subsequently severed tree which is held thereagainst by the other pair of arms.
In a modified form of the invention, both pairs of arms are formed as two parts pivoted together, as above mentioned, so that each pair can be used to either gather a newly cut tree or hold the accumulated trees.
