Concave Furrowing Disk With Trailing Tool Patents (Class 172/181)
  • Patent number: 8020629
    Abstract: A low till agricultural implement has a frame with a hitch for attachment to a tractor. An shallow-angled blade gang composed of an array of parallel ultra-shallow inclined disk blades is mounted to the front of the frame, and is followed by at least one wheel, spiral reel, and spike tooth harrow. The ultra-shallow inclined disk blades are mounted perpendicular to rotating shafts, and slice through field residue and soil with minimal lateral movement of material. The blades of the following reel then make cuts nearly perpendicular to those made by the circular blades. A trailing rolling basket or other finishing implement follows the spiral reel. The implement aids in drying the soil surface layer. Also, by cutting up residue and evenly spreading debris and topsoil, the implement helps to warm up the soil.

  • Patent number: 7017675
    Abstract: A one-pass primary tillage machine provides a combination of shallow and deep tillage, residue cutting and mixing, and clod size reduction and leveling of the field to prepare the field for the next planting season. A front group of flat coulters slice through the residue to reduce its size, followed by deep shanks that improve the tilth of the soil to a point below the intended planting depth. Following the shanks, a group of concavo-convex conditioning discs mix the residue with the soil, reduce clod size, and level the field.

  • Publication number: 20030085045
    Abstract: A disc gang is provided that is suitable for use as part of a multifunctional seedbed preparation implement or in a standalone disc harrow. The disc gang is configured to permit a gang angle of the disc gang to be adjusted to accommodate differing soil conditions and/or to obtain different tillage characteristics. The disc gang may include a frame mounted on a mainframe of a primary tillage implement such as a cultivator. The frame includes a main beam mounted on the implement's mainframe and a disc support beam connected to the main beam and supporting a plurality of rotating discs. The gang angle can be infinitely adjusted through a designated range by pivoting one end of the disc gang about a vertical pivot axis while permitting another end portion of the disc gang to slide along a support surface for that end.

  • Patent number: 6554080
    Abstract: A motor grader can be adapted for laying down a layer of granular material such as base rock or cold mix asphalt by mounting a dispensing hopper attachment onto the front of the motor grader and a spreading and leveling screed onto the moldboard. As the motor grader advances, it pushes a dump truck that continuously loads materials into the hopper. Those materials are in turn continuously discharged at a metered rate of flow through the bottom of the hopper and onto the roadbed. The resulting swath of materials passes between the front wheels of the grader as the grader continues to advance, whereupon the screed engages the swath and spreads the materials in opposite lateral directions while leveling them to the desired depth.

  • Patent number: 5152349
    Abstract: A primary tillage apparatus includes a plurality of primary tillage tools and a coulter assembly for each primary tillage tool including first and second coulters positioned directly forward of the primary tillage tool, the coulters being mounted to diverge in a v-shape relative to the direction of travel such that the separation between the edges of the coulters increases in a rearward direction, and concave working surfaces of the coulters face outwardly away from one another, the weight of the implement frame and the action of the primary tillage tools causing the coulters to penetrate the soil ahead of the tillage tool and to press into any residue encountered, the cutting edges of the coulters gripping the residue and drawing the residue outwardly in opposite directions, tearing the residue in two and clearing the residue to the sides and out of the path of the primary tillage tool located rearwardly of the coulter assembly.

  • Patent number: 4446924
    Abstract: A tillage system includes forward and rear sets of widely spaced discs and a set of plow points. The discs in the forward set are mounted at spaced intervals so as to leave alternate strips of worked and unworked soil of substantially equal width. Each disc of the rear set is mounted in a strip of soil left unworked by the forward set to complete the working of the top soil. The plow points are located in the furrows of one of the sets of discs (preferably the rear set) to permit some deep plowing. The working depths of the points and discs are independently adjustable. The system is designed for operation at high speed to provide complete coverage of the soil with minimal double working by the discs. It permits deeper penetration by the discs and a controlled amount of deeper plowing by the points while leaving a finished contour which is substantially free of ridges and furrows.
