  • Patent number: 7487731
    Abstract: Apparatus for applying liquid-solid dispersions to soil. Valves are provided which permit cleaning. An elongate conduit, with an aperture at one end, and a first valve proximate such aperture may be opened to permit passage of a pig member. An upwardly extending conduit is “T'ed” off the elongate conduit, and connects with a manifold and a plurality of supply tubes to direct the liquid-solid dispersions to the soil at various points along the frame of the applicator. A second valve may be provided on the upwardly extending conduit, which may be closed to prevent initial supply of the liquid-solid dispersion to the apparatus and instead flow to the aperture to prevent plugging during initial operation. The second valve, when closed, further serves as an anti-siphoning valve to prohibit further supply of liquid solid dispersion to the manifold. A method for cleaning such apparatus is further disclosed.

  • Patent number: 7404365
    Abstract: An apparatus for application of a liquid manure to soil, possessing a frame which is adapted when towed over soil to apply such to the soil. A supply conduit, having a distal end and a proximal end is provided. The distal end thereof is adapted to be releasibly coupled and in fluid communication with a flexible supply hose which supplies the liquid-solid solution, such as liquid manure, to the distal end of the conduit. The proximal end of the conduit is in fluid communication with a manifold which thereafter via a plurality of supply tubes supplies such liquid/liquid solid dispersion to the soil. An intermediate portion of the supply conduit is flexible. A boom member at its distal end supports a distal end of the supply conduit. A proximal end of the boom member is pivotably coupled to the frame to allow pivotal movement of the distal end of the boom member in at least a horizontal plane.

  • Patent number: 7252043
    Abstract: An apparatus for application of a liquid or liquid-solid dispersion to soil, which is adapted when towed over soil to apply such liquid-solid dispersion to the soil. A supply conduit, having a distal end and a proximal end is provided. The distal end thereof is adapted to be releasibly coupled and in fluid communication with a source of liquid-solid solution, such as liquid manure. The supply conduit is pivotally coupled, via a pivot member, to the frame of the implement to permit the supply conduit to be pivoted in a substantially horizontal plane. The pivot member is coupled at one end thereof to the supply conduit at a location intermediate the distal end and the proximal end of such supply conduit, and is pivotally coupled at an opposite end to the frame of the apparatus. A manifold portion, having a plurality of manifolds thereon, is provided.

  • Patent number: 6923266
    Abstract: An outboard tine device for soil-aerating equipment is disclosed comprising a hub having an aperture, a rotatable shaft within the aperture and mounted on the soil-aerating equipment, an outboard tine assembly comprising a plurality of outwardly protruding tines, and a securing member adjacent an outboard side of the outboard tine assembly removably securing the outboard tine assembly to the hub, wherein the securing member and hub are respectively positioned on opposing sides of and adjacent to the outboard tine assembly, wherein the outboard tine assembly, hub and securing member are positioned outboard of the mounting assembly resulting in the outboard tine assembly being cantilevered from the shaft. A dual outboard tine device is also disclosed. The outboard tine device is directed to uniform aerating and enabling easier replacement of damaged tines.
