摘要:
A land roller implement has a center frame and a center roller. Wings are pivotally mounted to a wing bracket pivotally mounted to, and extending rearward from, each side of the center frame. The wings and center frame thus move independently up and down when operating. The bracket is locked and wheels mounted on the brackets move the rollers up for transport. Inner and outer rollers on each wing are aligned and separated by a roller spacing. An overlap roller rolls over theis spacing. In transport position the right and left wings extend rearward from the center frame and right and left overlap rollers are aligned with, and adjacent to, each other. During a turn, the wings pivot and move closer to each other. To avoid contact with each other the right and left overlap rollers move forward and rearward to offset positions.
