  • Patent number: 7762745
    Abstract: The present invention is a silt fence installer of unique design wherein the frame is angular rather than longitudinal and the fabric chute assembly is oriented parallel with the angular frame. This arrangement results in an installer with a generally perpendicular trailing edge, a fabric chute assembly with a closed leading edge and no need for hinged relationship between the sidewalls, and simple fabric threading with a single directional turn of the fabric. Further, the angular frame results in a shorter installer able to be more responsive to turns. In addition, the invention includes a sliding offset hitch wherein a silt fence installer may be adjusted laterally by hand due to strategic placement of rollers.

    Abstract: An assembly for installation of a silt fence. The assembly comprises a cutting member, a silt fence guide, and a spool of silt fence material. The cutting member may be a plow blade, a trenching assembly, or another cutting means. A vibrator may be utilized to enhance the effectiveness of a plow blade. The silt fence guide may be a grab wheel adapted to place the silt fence material into an opened trench or other means. The spool of silt fence material is preferably adjustable to change a position at which the silt fence material contacts the silt fence guide. Preferably, a roller or similar means is used to compact the soil proximate installed fence. Alternatively, a second cutting member and a second silt fence guide may be utilized to cut another trench. A second spool of silt fence material allows simultaneous installation of two fences. The assembly may be adapted to cut a curved path behind a work vehicle traveling in a generally straight direction.

  • Patent number: 5443126
    Abstract: The invention relates to a grubber tine of a tubular cross-section which, as compared to known grubber tines, give reduced weight and larger flexure and vibrations when moved through the soil, which gives reduced tractive power. The grubber tine is adapted to escape obstacles within the soil in that the grubber tine is pivotally suspended on a shaft. Bosses are attached to the grubber tine through friction forces between the bosses and the grubber tine at a preferably conical contact face, achieved in that the bosses are pressed into holes in the wall of the grubber tine. In the working position, the grubber tine rests against a shaft and is kept in place by means of a safety bolt adapted to be stretched off upon the occurrence of overload. The safety bolt may be combined with a resilient member, such that the grubber tine to a certain degree may yield upon load and then return to working position.

    Abstract: A cultivating implement include a soil working tool having an elongate substantially planar blade. The blade extends sidewardly and downwardly at an acute angle to the vertical so that its plane is substantially parallel to the direction of movement through the soil and so that soil is lifted without inversion over the blade during passage through the soil. A movable extension is mounted to the blade trailing edge and is adjustable between first and second rigid positions to adjust the lifting action on the soil and thus adapt it to a wide variety of soil types and moisture conditions. At the lower end of the blade is a shoe member with an upwardly and rearwardly inclined upper surface at a leading end thereof, and an upright and rearwardly extending side surface substantially parallel to the direction of travel to provide a bearing surface for resisting lateral forces on the tool due to lifting action of the blade. The shoe member imparts lateral stability and factilitates penetration.

  • Patent number: 4293043
    Abstract: The present invention relates to a shank assembly for a soil undercutter, which is similar to an extremely wide cultivator shovel which travels underneath the ground and cuts the roots from weeds and plants without substantially disturbing the surface of the ground. The shank assembly position can be adjusted by changing the length of a link which holds the shank assembly in position. As shown the link includes a spring trip with a near center type toggle trip release that prevents "floating" and will hold the blade in position until an obstacle is encountered. The shank and spring mounting rod are pivotally mounted with respect to a common pivot, and when the blade encounters an obstruction the toggle linkage releases permitting the shank to pivot rearwardly and upwardly, while the toggle linkage compresses the spring. The trip will automatically reset after the blade clears the obstruction.
