Abstract
A seeding implement grain box is provided with a single piece molded plastic insert at the bottom of the box that forms an array of funnel sections having open lower ends that align with the openings in the grain box bottom wall. The funnel sections have sloping walls between each bottom wall opening to cover the flat portions of the bottom wall between the openings, thereby allowing the seed grain to completely empty from the grain box.
