| 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. | ||||||

| A disc device for an agricultural machine includes at least one disc implement, an arm, at one end of which the implement is journalled in bearings at an axle, and a bearing, which is arranged at the opposite end of the arm and is adapted to be fastened at a transverse beam on the frame of the agricultural machine. The disc device includes in the circumference direction of the disc implement mainly equally distributed, freestanding, out towards the periphery radially extending, protruding parts, wherein each protruding part has an outer edge, which extends in the range 15-75 degrees in relation to the plane of the disc implement. | ||||||

| 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. | ||||||

| 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. | ||||||

| The invention refers to a disc (8) for an agricultural implement (1) comprising an annular, outside a predetermined center diameter (D) defined, soil-cultivating portion (44), a central, inside a predetermined center diameter (d) defined, dish-shaped portion (43), with a boss-receiving, inner side and between these portions an existing, annular connection portion (45) with fastening screw holes (46). The connection portion (45) is a truncated conical portion, the inner mantle surface of which is mainly straight or double-bowed with the convex side facing said inner side and a line through the opening plane in the hole opening of each fastening screw hole on said inner side forms an angle α with a plane that is perpendicular to the center line of the disc, wherein the angle α is 5°-10°. | ||||||

| The invention relates to a flexible disc (7) to be rotatably received on a coulter mounting (2) of a disc coulter (1) so as to face a cutting disc (5) for opening the soil (A). The flexible disc (7) can be arranged such that the flexible disc passes over a cleaning surface (10) of the cutting disc (5). The flexible disc is characterized in that the flexible disc (7) has a maximum peak distance (D) and a minimum peak distance (d) on the flexible disc rotational plane, said minimum peak distance differing from the maximum peak distance. The invention further relates to a disc coulter (1) comprising a mouth portion (9), which is provided for feeding seeds and/or manure between a cutting disc (5) and an at least partly flexible disc (7), and comprising a coulter mounting (2) for rotatably receiving the cutting disc (5) that is used to open the soil (A) and the flexible disc (7) that passes over a cleaning surface (10) of a cutting disc (5) cleaning face (12) which faces the mouth portion (9). The disc coulter is characterized in that the flexible disc (7) has a maximum peak distance (D) and a minimum peak distance (d) in the flexible disc rotational axis, said minimum peak distance differing from the maximum peak distance. | ||||||

| A blade sharpening system is provide that includes a base (70) and a pendulous arm (90) having a first end rotatably coupled to the base (70) by a pivot joint (92). The blade sharpening system also includes a sharpener (60) suspended by the pendulous arm (90) and configured to engage a generally circular agricultural implement blade (22) while mounted on the agricultural implement (10). The pendulous arm (90) is configured to enable movement of the sharpener (60) to accommodate lateral variations in blade profile. | ||||||
