ABSTRACT:
A soil working implement has a row of soil working tools that displace soil rearwardly and laterally. A side-plate is pivoted to each side of the implement frame and positioned adjacent the outer ends of the row to arrest the lateral movement of the soil. An elongated supporting roller is located to the rear of the row to support the implement and further work the soil. Each side-plate has a lower rim that rides along the ground and a guide element is attached to the rear of the side-plate to extend inwardly towards an outer roller end. The element is preferably a blade that is inclined to displace soil arrested by the side-plate and prevent ridging. The blade can be integral or attached to the rim.
