Abstract

A tree harvester for continuously cutting and accumulating trees and a method for using such a harvester is disclosed. The harvester has a frame with a cutting area and a large elongate accumulation area. A tree severing device is secured to one end of the frame and a continuous rail having accumulating arms secured to it extends from the cutting area to the rear portion of the accumulation area. The arms are equally spaced apart from each other along the rail, with each arm traveling in a continuous circuit along the rail. During use, the harvester is aligned with a row of trees to be cut. As the first tree is cut by the severing device, an accumulating arm is positioned behind the tree and moves it to the rear most available portion of the accumulation area. As the harvester travels down the row of trees, each tree in the row is cut and moved to the rear most available portion of the accumulation area.

Description

[0001] This application claims priority to US Provisional Application 60 / 088470 filed June 8, 1998. [0002] The invention relates to a fast tree felling device and method. More particularly, it relates to a tree felling device and method for rapidly and efficiently felling large numbers of trees in succession and stacking the felled trees. Background of the invention [0003] Since the late 1980s, there has been an urgent need for an economically viable method for continuously harvesting trees. Trees can be harvested quickly and efficiently with little resource cost. This high efficiency is coveted on forest farms where trees are planted in rows and harvested soon after planting, where a large amount of wood is produced per acre per year, but only a small amount is available per tree. material. [0004] Some inventors have attempted to increase the efficiency of felling and stacking harvested trees. For example, US5697412 to Kurelek discloses a logging device mounted on t...
