US Patent 9392738 Land roller implement having multi-roller wings with fold-over subframes

A land roller implement with fold-out wings features at least one raisable/lowerable roller on each wing that is carried on a movable subframe that is pivotally mounted to the main frame of the wing. The movable subframe is pivotal up into a folded position overlying the main frame of the wing so that the raisable/lowerable roller is elevated overtop of an adjacent roller on the same wing. This minimizes the width of the implement when the wings are folded in to lie longitudinally of the implement for transport.
