The notches are selected from many arcuate shapes and sizes. The notches taper from sharp to dull from one end to the other, but in use one can chose to lead with the dull or the sharp end of the notches. A method of making and using such coulters or discs is described and shown. | 01-20-2011 |
| 20110024141 | DISK FOR FARM USE, PARTICULARLY USED FOR FIELD PLOWING - This disk is a metal disk comprising a central ductile portion ( | 02-03-2011 |
| 20110162856 | WAVY DISC AND COULTER WITH NOTCHES - A wavy disc and coulter with notches and method of using same, the disc or coulter having plurality of waves formed in the blade by deviating the entire outer periphery of the variable wave coulter from a flat plane. A plurality of crests and a plurality of valleys are formed in the blade, wherein each of said plurality of waves comprises a first and a second crest and one valley between the first and second crests at the outer periphery thereof. A notch is disposed in each respective wave on the outer periphery of the blade and wherein at least a majority of the notch is disposed between the first one of the respective crests and the respective valley, such majority of the notch being closer to the first respective crest than to the second respective crest. | 07-07-2011 |
| 20110240319 | SHALLOW CONCAVITY SCALLOPED DISC BLADE - A shallow concavity scalloped disc blade particularly suitable for vertical tillage applications is disclosed. The disc blade comprises a generally circular plate having a peripheral radially toothed cutting edge, a smooth central portion configured to mountingly engage a harrow or like agricultural implement, and a curved scalloped (or fluted) portion adjacent to the central portion, the curved scalloped (or fluted) portion having a plurality of scallops formed between the flat central portion and the edge. The radius of curvature of the curved scalloped (or fluted) portion preferably is between about 850 mm and about 1000 mm, and more preferably about 900 mm. | 10-06-2011 |
| 20120168187 | FAST-ACTION HARROW-DISC COUPLING - The present invention relates to a fast-action harrow-disc coupling for fixing a harrow disc ( | 07-05-2012 |
| 20130037285 | Strip-Till No Build-Up Berm Builder Blade For Strip-Till Farm Implement - A berm building disc is designed to reduce the amount of soil that builds up on the inner surface of the disc as the disc pushes soil for berm formation. The disc has a disc body having an outer radial edge, and defining an inner concave surface and an outer convex surface. Features are formed on the inner concave surface to reduce the surface area or soil adhesion properties of the inner concave surface. | 02-14-2013 |
| 20140102738 | SURFACE TOPOGRAPHY OF AGRICULTURAL MACHINERY TOOLS THAT INTERACT WITH THE SOIL AND AGRICULTURAL TOOL WITH MODIFIED SURFACE TOPOGRAPHY - A substantial reduction in traction force demand can be achieved for agricultural tools with modified surface topography comprising dimples arranged in a parallelogram (hexagonal) pattern, the morphological unit of which is an equilateral triangle. | 04-17-2014 |
| 20140262384 | Segmented Coulter Disc - A coulter disc for use in an agricultural implement is divided into a plurality of segments each having an arcuate pattern of bolt holes offset by a radius r from a displaced center such that material removed in dividing said coulter is accounted for when the disc is reassembled on an implement. The coulter disc is provided with capture devices radially outwardly of the arcuate pattern that connect the edges of the segments to reduce distortion. | 09-18-2014 |
| 20140262385 | Coulter Disc Bolt Pattern - A coulter disc for use in an agricultural implement is divided into a plurality of segments each having an arcuate pattern of bolt holes offset by a radius r from a displaced center such that material removed in dividing said coulter is accounted for when the disc is reassembled on an implement. | 09-18-2014 |
| 20140299343 | Disc and Coulter with Center Depression for Strength - An agricultural disc having a one piece metal plate is adapted to be rotated about a rotational axis. An inner circular section of the disc is disposed generally along a first plane. A outer section of the disc is disposed generally radially outwardly from the inner circular section, the outer section has an outer periphery which does not lie in the first plane. A transitional section of the one piece metal plate has an inner portion thereof connected to the inner circular section, the transitional section also having an outer circular portion thereof connected to an inner periphery of the outer section. The disc can be, but is not limited to, a flat or wavy coulter or a disc which can be concave/convex, with or without cut out portions. | 10-09-2014 |
| 20150034344 | Wavy Agricultural Tillage Blade with Sharpened Edge - A method of making a tillage blade by obtaining a generally circular sheet metal steel disc having an outer peripheral edge. Waves are made in the outer peripheral edge of a circular steel disc in a predetermined pattern while the steel is cold. The outer peripheral edge is then sharpened at a predetermined acute angle with respect to a first plane by grinding. Then the disc is heat treated to make it harder so it will wear longer. If it is desired to have a concave/convex disc, instead of a coulter, then during the heat treating process the disc is deformed so that the sharpened portions of the peripheral edge remain generally in the first plane but a central portion of the disc is disposed at least partially in a second plane which is parallel to but spaced from the first plane. | 02-05-2015 |
| 20150289433 | WAVY DISC BLADE WITH NOTCHES - A wavy disc blade is provided. The wavy disc blade includes a first side, a second side, a central portion having at least one opening, and a wavy portion adjacent to, extending radially from and circumferentially about the central portion. The wavy portion includes a plurality of waves extending from the central portion to an edge portion, the waves forming a plurality of crests and valleys between the central portion and the edge portion. The wavy disc blade also includes a plurality of teeth formed along the edge portion. At least one of a first beveled portion may be formed on the first side at and along the edge portion and a second beveled portion may be formed on the second side at and along the edge portion. | 10-15-2015 |
| 20160000001 | Agricultural Drill/Planter/Coulter/Disc Blade with Sine Wave Edge - An agricultural tillage blade having a central opening is adapted to be disposed on a shaft for rotation to cut trash and penetrate into the soil. The blade has an outer periphery substantially in the shape of a sine curve formed about a circle. The outer periphery of the blade is sharpened to more easily penetrate the soil and cut trash. | 01-07-2016 |
