A rear row of shallow concave disc blades has a rear right portion and a rear left portion symmetrically disposed about the centerline of the implement. The rear right portion following behind the front right portion in a right path and the rear left portion following the front left portion in a left path when the implement is displaced through a field. The implement includes no ground engaging tool in the right path between the front right portion and the rear right portion, and no ground engaging tool in the left path between the front left portion and the rear left portion. The shallow concave disc blades have a concavity of between approximately 1.25 and 1.69 inches over an outer diameter of approximately 20 inches.
