Abstract
A method and apparatus for extracting a tree trunk, stump and main root from the ground while simultaneously severing the lateral roots, where the tree trunk is gripped by gripping members which are raised vertically to pull the stump and main root through generally annular root shearing members encircling the base of the tree trunk. The root shearing members remain stationary during the extraction operation. Preferably scraping members are positioned adjacent to the root shearing members to remove any dirt and debris.
Claims14
An apparatus for simultaneously extracting a tree trunk, stump and main root from the ground and removing lateral roots, said apparatus comprising a mobile power source vehicle to provide power to tree extraction operating means comprising a ground plate connected to said mobile power source means such that said ground plate can be raised from and lowered onto the ground, gripping means movably mounted on said ground plate to securely grasp a tree trunk, adjustable root shearing means connected to said ground plate to encircle said tree trunk at its base and shear any lateral roots, where said root shearing means are connected to said ground plate such that there is no relative vertical movement between said root shearing means and said ground plate, and raising means mounted on said ground plate and connected to said gripping means to vertically move said gripping means relative to said ground plate and said root shearing means such that said tree trunk, stump and main root are pulled through said ground plate and said root shearing means and said ground plate and said root shearing means remain stationary on the ground.
A method of simultaneously extracting a tree trunk, stump and main root from the ground while removing any lateral roots, the method comprising the steps of providing tree trunk gripping means, root shearing means connected to a ground plate such that there is no relative vertical movement between said root shearing means and said ground plate, and raising means mounted on said ground plate to vertically move said gripping means, then placing said ground plate adjacent said tree trunk, gripping said tree trunk with said gripping means, encircling said tree trunk at its base with generally annular root shearing means, and raising said gripping means and said tree trunk to pull said stump and main root through said root shearing means and said ground plate where said root shearing means and said ground plate remain stationary on the ground.
An apparatus for simultaneously extracting a tree trunk, stump and main root from the ground and removing lateral roots, said apparatus comprising a mobile power source vehicle to provide power to tree extraction operating means comprising gripping means to securely grasp a tree trunk, root shearing means to encircle said tree trunk at its base and shear any lateral roots, raising means to vertically move said gripping means relative to said root shearing means such that said tree trunk, stump and main root are pulled through said root shearing means, and scraping means to encircle said tree trunk to remove dirt and debris from said stump and main root.
