  • Patent number: 6640731
    Abstract: A planting tool for depositing seed and/or fertilizer within a furrow including a soil opener and a seed boot attached to the soil opener. The seed boot includes a synclinal shape housing and at least one furrow forming wing that protrudes below the body of the seed boot. Each wing of the seed boot has at least one wear resistant leading insert positioned in front of and in juxtaposition to at least one wear resistant trailing insert that are each secured to at least a portion of the lower forward surface of the wing and that are each in juxtaposition to a portion of a furrow forming edge of the wing. The wear resistant leading insert and the wear resistant trailing insert have cobalt concentrations of from about 15 to 22 weight percent, and from about 8 to 14 weight percent, respectively.

  • Patent number: 5983813
    Abstract: The invention relates to a spreader for use on a delivery tube of a seeding tool. The spreader is mounted for adjustable positioning in the product stream providing a selectable width of product scatter. The invention preferably includes a tapered deflecting surface with a convex laterally angled surfaces for achieving an even scatter pattern, especially over the varying scatter widths. The deflecting surface is pivoted or advanced into the product stream to change the breadth of surface struck by the product as a result causing different scatter patterns. In a preferred embodiment the spreader includes a channel for mounting onto the delivery tube with a pivot pin pivotally securing it adjacent the outlet and selectively adjustable securing points for angular adjustment. The spreading deflecting surface is separated from the outlet in the direction of product stream so that deflected product is not shielded by the delivery tube.
