ABSTRACT:
A soil cultivating implement comprising soil working members having tines, the members being arranged in a row that extends transverse to the direction of travel. A ground roller is freely rotatable and positioned to the rear of the row of soil working members. In order for the roller to support the implement on the ground and regulate the maximum depth of penetration of the soil working members into the ground, the roller has crowns or assemblies of projections which comprise substantially radial portions and outer end portions which are bent over laterally in opposite directions by significant angles and also rearwardly with respect to the direction of normal roller rotation. In addition, they are widened towards the end in the direction of their rotational movement. Scraping members are positioned between the successive assemblies or crowns of projections and the roller may have a central tubular shaft or carrier of a different diameter.
