ABSTRACT:
A tilling implement has a front row of concave disc blades having a front right portion and a front left portion symmetrically disposed about a centerline of the implement. A rear row of 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 follows behind the front right portion in a right path and the rear left portion follows 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. A ground engaging tool is disposed generally along the centerline of the implement between the right and left paths.
