The levelling-aid crumbler roller arrangement is fixed to a cultivating implement via a support frame. The roller arrangement comprises two height-adjustable and sprung rollers, which are arranged inclined to the direction of travel to form an obtuse angle. The casing faces of the rollers have right and left-handed scroll lines. The support frame has two longitudinal spars (3, 4) on which are two cross spars (5, 6) which carry the rollers.
