  • Patent number: 7610698
    Abstract: An apparatus for extracting plant species of varying heights and varying diameters adapted to be mounted on a conventional land vehicle includes a frame and an extracting member rigidly attached to and extends outwardly from a bottom edge of the frame. The extracting member includes a first elongated extracting portion having a knife-like free end, a pair of second extracting portions each positioned adjacent a respective edge of the first elongated extracting portion and having a cutting edge formed generally perpendicular to the respective edge of the first elongated extracting portion, and a pair of third extracting portions each connecting an end of the cutting edge of the second extracting portion with a respective end of the bottom edge of the frame. A pair of elongated member are attached to the rear surface of the frame for attaching it to the land vehicle.

  • Patent number: 7381010
    Abstract: The present invention is a system and method for removal of buried objects. According to one embodiment of the invention, a crane with a vibrator casing driver is used to lift and suspend a large diameter steel casing over the buried object. Then the casing is driven into the ground by the vibratory driver until the casing surrounds the buried object. Then the open bottom of the casing is sealed shut by injecting grout into the ground within the casing near its bottom. When the seal has cured and hardened, the top of the casing is lifted to retrieve the casing, with the buried object inside, from the ground.

  • Publication number: 20020043373
    Abstract: A waste recovery station for a beach cleaner for recovering waste raked up by a beach cleaner. A waste recovery station for a beach cleaner includes a pair of station members arranged in parallel with each other through a required spacing. Each station member is provided with a pair of support posts with a foot such as, for example, a circular or square flat plate fixed to a lower end of each support post and is also provided with a guide member fixed to upper ends of the support posts. In the guide member, a longitudinally intermediate portion is formed as a horizontal portion and front and rear end sides are formed as slant portions and are bent downwardly at an obtuse angle. The beach cleaner A is lifted by the guide members while passing between the station members, whereby waste caught on rakes is allowed to drop onto the sand.

  • Patent number: 6286605
    Abstract: A vine cutter for cutting entangled vines of potato plants in front of a potato harvester so that the vines do not become entangled and accumulated upon a front portion of the potato harvester. The inventive device includes a frame having a pair of upper members and a pair of opposing lower members, a first disc and a second disc journaled to the frame, a third disc journaled to the frame below the first disc and second disc, a ground engaging rim attached coaxially to the third disc, and a motor mechanically connected to the first, second and third discs. The first disc, the second disc and the third disc are vertically orientated, and a portion of the discs overlap and are juxtaposed to one another. A portion of the third disc is between the first disc and the second disc for severing the vines. The discs preferably include a plurality of notches projecting into their respective outer perimeters. The discs may have different sizes with respect to one another.

  • Patent number: 4466490
    Abstract: A hydraulic weeding apparatus consisting of an elongated hollow tubular shaft being attached to a hand grip type body having a coupling for attaching the device to a source of pressurized fluid such as a common garden hose. A positionally adjustable, hook-type gripping device is spaced from the open end of said tube and is arranged with an outwardly extending free end which is arranged to encircle and grip the base of a weed root when the shaft is rotated. A splash shield is positioned above the gripping device to prevent the fluid from flowing upwardly along the shaft so as to protect the user. A valve can be provided in the body of the device for controlling the flow of fluid through the tubular shaft whereby the open end of the shaft can be inserted adjacent to the root of a weed to a depth where the gripping device can attach to the loose weed so as to easily remove it.

  • Patent number: 4305213
    Abstract: This invention involves new and unique apparatus suitable for safely and quickly removing a row of bare root nursery trees. More particularly, this invention teaches a lightweight and raised frame which supports a plow or blade, a power source, a seat for the operator and the controls. Weighted wheels are attached to the lightweight frame by four support members such that the wheels straddle a row of trees to be removed as the frame moves over the top of the row of trees. A U-shaped blade or plow is forced into the earth such that the blade cuts under and around the trees as the apparatus moves along a row of trees and the blade moves under the row of trees. Thus, the trees can be easily removed and the dirt shaken therefrom after the apparatus has moved past. According to one embodiment, a power source such as a small gasoline engine drives a hydraulic pump which is then used to hydraulically actuate the blade and to provide hydraulic power to four small hydraulic motors for independently driving the wheels.

  • Patent number: 4164981
    Abstract: An agricultural harvesting assembly designed to remove vines and like undesirable growth from cultivated trees, plants and the like, comprising a frame movably and adjustably attachable to a tractor or like towing vehicle. A gripping head is movable and adjustably attached to the frame by an orienting means movably interconnected between the gripping head and the frame in such a manner as to absorb shock when the gripping head engages a tree from which vines are to be removed. Head disposition means and additional adjustment means are mounted on said frame and movably interconnected relative to the gripping head so as to position the gripping head between an operative and non-operative position and also in predetermined path of travel relative to a tree or obstacle intended to be encountered.
