A coulter disc mounting assembly for a tillage implement supports acoulter disc thereon to be angularly offset from the forward working directionof theimplement. The tillage implement typically includes a frame supporting aplurality oftool shanks thereon, each having a mounting surface adapted for mounting arespectiveshovel opener thereon in which the mounting surface has a width which issubstantiallyperpendicular to the forward working direction. The disc mounting assembly hasa hubwith a mounting surface for fastening against the mounting surface of one ofthe toolshanks in which the hub supports a coulter disc thereon such that the coulteraxis isoriented non-perpendicularly to the forward working direction.
