ABSTRACT:
A tine for use on rotary soil working members that are rotated about upwardly extending axes has a upper fastening portion joined to a lower soil working portion. Each of the portions has a longitudinal axis and one axis is preferably inclined to the other so that the soil working portion can be held in a trailing or a leading position. The soil working portion has a oval cross section region that merges into a polygonal cross section region towards the lower tip of the tine. The fastening portion has means for fastening the tine to support holders of a soil working member.
