Abstract

To form a furrow for row guidance systems, a shank is mounted on a frame forwardly of a wheel which includes a V-shaped tire. The shank opens the ground and the tire crushes clods and packs the sides of the furrow. Depth bands on each side of the tire shape the edges of the furrow and prevent loose dirt from rolling back into the furrow. When utilized to reform a furrow, the frame is pivotally connected to the implement for rocking about an upright axis to allow the wheel to trail and average out guidance system corrections and driver steering corrections so that the reformed furrow will be more accurate for the next operation.
