  • Publication number: 20140262364
    Abstract: A cultivator for efficient clearing of overgrown land to prepare for planting, especially suited to operating in remote, or hard-to-maneuver-in areas, including towing by a light vehicle, comprises a frame interconnecting to hold a drum with protruding gusseted rods at right angles to the forward movement of the frame. A pair of wheels is mounted to the frame such that when the frame is flipped over, the wheels keep drum and rods from contacting ground and vegetation. A height-adjustable, removable grader bar is connected between the wheels. A trailer hitch is connected to the frame by a removable pin, reversible for towing the cultivator with the drum and rods engaging the ground for land clearing and preparation for planting, or alternatively with wheels engaging the ground for leveling ground with the grader bar or transportation. The drum's weight can vary by filling with solids or fluids.

    Abstract: The invention relates to a machine for displacing grindstones with a milling cutter (28, 30). The inventive machine is laterally guided along a grindstone, in a displacement direction, and removes a layer of material from the grindstone through milling every time it passes the grindstone. The material removed by milling drops upon a conveying device (88) used to deposit the material in an area offset from the milled grindstone. The milling cutter has two side rotating milling heads whose rotation axis extends substantially in the displacement direction or forms an acute angle relative to the displacement direction.

  • Patent number: 4903780
    Abstract: A mobile, self-propelling crushing machine includes a structure essentially consisting of two beams, on which a central frame is welded. The central frame houses a rotor which is supported on a frame, which, in one form, is lowered by hydraulic cylinders fixed to the frame. In another form, the frame is lowered by four mechanical jacks being driven by a single hydraulic motor. Thus, the penetration of the rotor into the soil to be treated does not depend only on its own weight, but especially on the action of the just-mentioned hydraulic cylinders or mechanic jacks. The rotor is driven by two hydraulic motors which are opposite to one another and which are self-adjusting so that when a pressure transducer signals a pressure increase to the hydraulic motors of the rotor due to an increased effort, the forward movement speed of the machine, which moves on tracks, decreases as a consequence.

  • Patent number: 4862969
    Abstract: A method for cultivating plantable soils, more particularly forest soils, by breaking-up and working-in plants and parts of plants lying upon the soil, for example leaves, needles, twigs and branches. To this end, a plurality of elements, flexible in all directions, tautened by centrifugal force, and secured to a shaft, are caused to rotate by the said shaft, the radius of rotation of the ends of the said elements being greater than the selected distance between the axis of rotation of the shaft and the surface of the ground. In order to be able to mechanically cultivate larger areas of substantially uneven and non-homogeneous forest soils, the horizontal axis of rotation of the shaft is also subjected to an oscillating pivoting motion about a vertical axis, the axis of rotation of the shaft being kept substantially radial to the pivot-axis and being moved in a circle which is parallel to the surface of the ground.

  • Patent number: 4359101
    Abstract: This invention relates to an auger and to a plow including such auger. This specification discloses an auger which is suitable for use even in the difficult terrain encountered in typical reforestation operations. An auger in accordance with this disclosure has its axis extending in the direction of movement of the plow and is arranged to rotate in a direction opposing the forward movement of the plow. The auger has a plurality of generally helical turns. Sections of the ground engaging portions around the periphery of the turns have an angle of attack in a plane at a selected angle to the axis of the auger and other sections have angles of attack in planes at a different angle. These ground engaging sections of the periphery are preferably teeth which because of the difference in angles discussed above attack the ground at different cutting angles.
