Abstract
A seeding implement has an implement frame with a lateral frame member. Spoked wheels rotate about a wheel axis that is fixed with respect to the implement frame. Shanks are mounted to the lateral frame member such that each shank is movable with respect to the frame. Each spoked wheel rotates about the wheel axis in a plane that is vertical, aligned with, and forward of, a front face of a corresponding shank, and ends of spokes pass adjacent to a front face of the shank. A spoke clearance distance between the ends of the spokes and the front face of the corresponding shank remains within a trash clearing range as the shank moves with respect to the implement frame from a first operating position to a second operating position that is below the first operating position.
