A cultivating implement with a coupling mechanism for attachment to the rear of a prime mover has a row of rotatable tined supports mounted on upwardly extending shafts. The implement has an elongated frame to house the drive elements for the row of supports which extend transverse to the direction of travel. A ground roller is pivoted to the frame to trail the tined supports and interconnected with the frame through arms that have adjusting means. The adjusting device can vary the distance between the frame and the ground roller so that, in effect, the working depths of the tines are regulated. The implement is supported solely by the roller, coupling mechanism and the tines. A seed drill with coulters is connected to the implement so that seeds can be directly sown in the soil worked by the tines. The tines are configured to intensely work the soil and the roller is positioned to support much of the weight of the implement and crumble the soil.
