ABSTRACT:
The tree cutter device has a quick release mechanism for the gripping of the tree to be cut and for the quick release after cutting. The gripping mechanism is actuated upon contact of the tree cutter device with a tree with the gripping force with a tree at a maximum when the tree cutter device is fully against the tree. After cutting the tree, the gripping mechanism is released by the moving of the tree cutter away from the tree or by releasing the hydraulic or pneumatic cylinder driving the tree clamp in the non-mechanical modes. In the mechanical mode a combination of levers and tensioning springs comprise the tree gripping mechanism that is actuated by a trigger arm that is actuated by the contact of the tree cutter device with the tree. A boom arrangement biases the tree away from the tree cutter as it is being cut, and in a preferred mode includes a kick arm arrangement which at a lower end enters the cut as a tree is being cut and felled, holds the cut open, and forces the tree at the lower end away from the tree cutter and the operator.
