ABSTRACT:
A rotary harrow or cultivator tine has an upper fastening portion that is tightly received in a holder. The fastening portion is integral with a lower soil working portion that terminates in a tip and the two portions are angled with respect to one another. The soil working portion has a generally round cross section for a part of its length that is tapered outwardly to form a leading rib with respect to the intended direction of rotation of the tine. In the lower region adjacent the tip, the cross section of the soil working portion becomes less round and can merge into a polygonal cross section region having grooves and flat sides.
