  • Patent number: 6644226
    Abstract: The present invention relates to a seed sowing apparatus which includes a substantially flat circular disc (1) mounted on a frame so as to be rotatable about horizontal axis (2) while partly embedded in soil (3) and drawn in a forward direction substantially parallel to the soil surface and substantially perpendicular to a disc axle. The apparatus also includes at least one blade (10) having a leading edge (11) defined by the intersection of two opposite side surfaces and structure (41, 45) for mounting the blades on the apparatus so that the leading edge (11) is held close to or in intimate contact with the disc (1), wherein the at least one blade's leading edge (11) is inclined in a plane of the blade such that an angle of the leading edge (11) with respect to an arc (A, B, C) of the disc surface passing beneath the leading edge (11) is zero or positive over the entire length of the leading edge (11).
