An attachment for a cultivator includes an elongated soil engaging roller with longitudinal elements held around the circumference of the roller by supports. The supports are spaced apart profiled plates or pairs of plates having anchorages and apertured lugs alternatively positioned around their peripheries to affix and loosely retain the elements respectively. The elements are helically wound about a central tubular support which forms the axis of rotation for the roller. Alternative elements can be of different cross sections from one another and the elements can be tubes, rods and/or hollow oblong elements. The attachment is mounted to the rear of a cultivator on arms pivoted to the cultivator frame for vertical movements and/or adjustments with respect to rotary soil-working members of the cultivator.
