The attachment is capable of excavating and planting a tree and root ball using a single hemispherical scoop with a fixture nestled within. The scoop rotates under the tree to excavate the tree and root ball. The fixture stops the root ball from rotating until the root ball is encompassed by the scoop and fixture. The loader-motor vehicle manipulates the attachment and tree from a ground contacting position to a transporting position. In this transporting position a tree is nearly horizontal with its root ball encompassed by the scoop and the fixture. When planting, the root ball is placed within a hole. The scoop passes from under the root ball while the fixture stops the root ball from rotating. The root ball is released from the scoop and fixture, planting the tree.

  • Patent number: 6484766
    Abstract: A stump grinding wheel includes a wheel member having a plurality of receiving brackets. Each receiving bracket includes a cutting tool channel. A cutting tool is received in each of cutting tool channel. Each cutting tool includes an elongated shaft having a base end and a distal end, and a cutting tip at the distal end. A stop is defined on the elongated shaft between the base end and the distal end and is configured so that it permits gauging of the distance between each receiving bracket and a respective cutting tip.

  • Patent number: 6431231
    Abstract: The stump grinder has a rotating cutting wheel that is mounted onto an arm for raising and lowering movement and is driven by a hydraulic motor. The arm is capable of being moved about a generally upright axis to control the rate of laterally feed of the cutting wheel. The actuator movement is controlled as a function of the pressure to the hydraulic motor driving the cutting wheel so that as the pressure increases, the rate of feeding movement laterally of the cutting wheel is reduced. The rate of movement is controlled in both directions of swinging of the post about an upright axis, by utilizing variable opening or proportional flow pilot operated valves on the lines to the actuator for controlling the swing. As pressure to the motor increases the variable outlet or proportional pilot operated valve connected to the pressurized end of the swing actuator opens a greater amount diverts a portion of the hydraulic fluid flow to drain to slow movement of the swing actuator.

  • Publication number: 20020104237
    Abstract: Provided herein is a device which is useful in removing trees, stumps, and the like from various landscapes. A device according to the invention may be attached to existing earthmoving equipment, preferably in the place of a conventional bucket used on a track driven or tractor mounted backhoe attachment or other functional portion of a hydraulic excavator that is adapted to receive a bucket. A device according to the present invention may be caused to be operated beneath the surface of the ground, as in cases where it is desired to remove root masses and whole trees, such as mesquite and other species. In an alternate embodiment, a device according to the invention is useful above-ground for grasping small cedar trees and the like by means of grasping sabres affixed to the device. Methods for the use of such devices are provided.

  • Patent number: 6401369
    Abstract: A grubbing tool is provided for attachment to an excavator or other earth working machine, of the type having extensions from the boom such as a dipper stick and dipper stick linkage. The tool is moved arcuately and vertically to pull rooted brush having substantially sized taproots. The excavator's power is optimized at the cutting blade by the attachment of the dipper stick and dipper stick linkage near the top of the tool, as well as, the sizing and the configuration of the two primary side members. The cutting blade and both side members have both front and rear cutting edges, allowing a fore and aft pattern of approaching brush which optimizes tool effectiveness. The side members have substantially straight front and rear edges, which can be positioned flush with the disturbed surface following brush removal, providing a leveling function as the tool is moved laterally.

  • Patent number: 6401831
    Abstract: A tool, for mounting on a powering vehicle for transport, vertical motion and pivotal motion about a horizontal axis, provides a frame having connecting structure to interconnect with the powering vehicle. The frame carries extracting structure having plural laterally spaced extracting tines extending forwardly from the lower frame portion. At least one extracting tine has at least one depending vertical fin to increase tine strength and direct tine motion in a horizontal plane upon insertion through the earth; at least one extracting tine has at least one laterally extending horizontal fin to increase tine strength and direct tine motion in a vertical plane upon insertion through the earth; and at least one extracting tine has at least one soil retaining plate to aid support of material thereabove. The fins and plates tend to separate earth above and below the course of their insertion.

  • Patent number: 6382113
    Abstract: A device for transplanting trees or bushes having at least two spades that can be adjusted against each other. These spades can be set between an open and closed position by means of a pair of attached servo-drives. When in the open position, the spades are removed from each other by a space corresponding at least with a diameter of the tree or the bush to be transplanted. When the spades are in their closed position, they complement each other, forming a partial spherical cup. To reduce the resistance of the spades as they penetrate the soil, the cutting blade of the spade has the shape of a corrugated ground edging. These corrugated ground edges have alternating elevations and recesses, whereby the elevations of the cutting blade provide sufficient stability and safety against breakage. The ground surfaces that oppose each other on these spades are disposed on alternating sides to allow the cutting blades to overlap.

  • Patent number: 6308440
    Abstract: An excavation attachment for a powered loader, e. g., skid steer loader, front end loader, etc., provides considerably greater leverage for removal of stumps, large imbedded concrete blocks and stones, etc., from the underlying surface. The attachment includes a transverse cylinder or drum with one or more tines extending generally radially therefrom. The attachment is secured to a conventional front end loader, skid steer loader, etc., and the tines inserted beneath the object to be moved. The drum is lowered, and the attachment is rotated using conventional load bucket tilt hydraulics. The drum serves as a fulcrum immediately adjacent the prying tines, thereby providing a considerable increase in available force and precluding lifting of the opposite end of the machine if the load is too great. A second embodiment includes one or more hydraulically actuated tines opposed to the fixed tines, for use as a grappler device.
