Abstract
A tree delimbing system which utilizes a “drive-through” gate assembly having a plurality of pre-dimensioned apertures formed therein for removing tree limbs from tree trunks of various dimensions. Each aperture is dimensioned to selectively receive a plurality of tree trunks of varying diameters for subsequent limb removal. A single gate structure pivots from an upright (vertical) position to a lowered (horizontal) position upon impact with a skidder with attached felled trees. The impact of the skidder forces the gate down for tree transport therethrough. Once the trees have cleared the gate, a counter weight attached to the gate by cable returns the gate to its upright position. The trees are then rearwardly pushed through the apertures in the gate by the skidder to remove the limbs. The gate assembly forms an independent and stationary structure with anchors for securing the structure within surrounding terrain.
