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. A forwardly facing leading edge of a tapered spreading surface is directed into the product stream preferably between 15-30 degrees to the stream at approximately 65 degrees to the horizontal to deflect product forwardly and laterally in an even pattern.
