Embodiments relate to a tool for digging root balls of trees. The digging tool uses at least two cutting members that move in different paths for digging through the soil and cutting through a portion of the tree's roots. One cutting member moves along a substantially linear-path thereby forming a portion of a side wall of the root ball. The other cutting member moves along an arcuate path for forming a lower wall of the root ball. When the root ball is formed, the tool can be used to remove the root ball and the tree from a first location and move the tree to a second location. The size of the cutting members can be selected to form a root ball of a desired shape and size to allow the tree to continue growing at the second location.

A stump extraction device that includes two opposite jaws, two opposite cutting blades that are extensions of free ends of the jaws, a rotation device, and fixing elements that are configured to rigidly fix the stump extraction device to a desired object. The rotation device is configured to rotate the body and the jaws with respect to the fixing elements. A moving working machine includes the stump extraction device and a knuckle boom assembly, to an end of which the stump extraction device is rigidly connected. The moving working machine may be a crawler excavator. In a method, roots in the ground are cut off from a stump by closing of the jaws, and the stump is separated from the roots by lifting the stump extraction device by means of the knuckle boom assembly.

An apparatus for extracting trees, stumps, posts and similar structures from the ground is attached to a 3-point hitch tractor accessory. The apparatus comprises a base frame and a lifting frame. The base frame includes a pair of vertical guides for confining a corresponding pair of vertical rails on the lift frame. A piston/cylinder type of linear motor is connected between the base frame and lifting frame to translate the lifting frame relative to the base frame. A pair of independently controlled gripping cylinders that are connected to respective gripping cams are mounted on the lifting frame. A tree is extracted by engaging the gripping cams against the tree and translating the lifting frame.

A system and method for an adapter device. The adapter device can be used to couple to a pole for positioning or extraction. The adapter body has a first end coupled to a guiding edge and a second end coupled to a gripping edge. A securing device couples the adapter coupler to the adapter body via at least one coupler guide. The adapter coupler exits the coupler guide and forms a closed loop. When pulled, the closed loop tightens around and grips the pole.

There is disclosed a system and methods of use for quickly and efficiently excavating, cross-cutting, splitting, and loading or stockpiling tree stumpage and other tree or organic materials, as well as for performing ground cleanup operations. One embodiment provides a stump harvester for attachment to a distal end of an excavator arm. The stump harvester may include front and back jaw assemblies configured to pivot between open and closed positions. The back jaw assembly may include a knife arm having a cutting blade that extends along a majority of a front side of the knife arm. A centerline plane may bisect a cutting edge of the blade. The front jaw assembly may include a planar-aligned dual anvil configured to sheath the cutting edge of the blade when the front and the back jaw assemblies move into the closed position. Other embodiments are disclosed.

The base frame includes a pair of vertical guides for confining a corresponding pair of vertical rails on the lift frame. A piston/cylinder type of linear motor is connected between the base frame and lifting frame to translate the lifting frame relative to the base frame. A pair of independently controlled gripping cylinders that are connected to respective gripping cams are mounted on the lifting frame. A tree is extracted by engaging the gripping cams against the tree and translating the lifting frame.

A tree stump removal device is disclosed. The device includes an annular housing having cutters attached thereto. A method of removing a tree stump is disclosed that includes lowering a tree stump removal device into the ground surrounding the tree stump to sever some of the horizontal roots extending from the tree stump.

An extraction device eases the task of removing a post, bush or the like from a ground surface. The device includes a pair of legs pivotally coupled together at respective first ends of the legs. A bar is pivotally coupled to a first one of the pair of legs. The bar has a notch extending upwardly into a bottom edge of the bar. A projection is coupled to a second one of the legs. The projection is insertable into the notch to secure the legs in a static position relative to each other. A connector is coupled to an associated one of the legs proximate the first end of the pair of legs. A ratcheting mechanism is removably coupled to the connector. A cable is removably coupled to the ratcheting mechanism for extending around a structural object for removing the structural object from the ground surface.

A tree stump removal device is disclosed. The device includes an annular housing having cutters attached thereto. A method of removing a tree stump is disclosed that includes lowering a tree stump removal device into the ground surrounding the tree stump to severe some or all of the horizontal roots extending from the tree stump.
