ABSTRACT:
A standing tree is gripped by a gripping device, lifted and separated from its root system by a cutting device acting in parallel with the longitudinal direction of the tree, the roots being separated from its trunk accelerating the cutting device vigorously relative to the gripping device in the direction away from it, while storing a substantial amount of kinetic energy in the considerable mass cutting parts which in conjunction with the mass of inertia of the tree is used for the cutting of the roots of the tree.
