First Claim
1. A tine for mounting on a rotatable shaft of soil aeration and cultivation equipment, comprising:
- mounting means at an attachment end of the tine;
a tip at a ground-engaging end of the tine opposite the attachment end;
leading and trailing convex curvilinear edges disposed opposite each other and converging toward the attachment end and the tip; and
first and second opposed faces substantially meeting at each of the leading and trailing convex curvilinear edges;
wherein a centre line of the tine passes through, forwardly of, or rearwardly of, the axis of rotation of the rotatable shaft when the tine is mounted on the rotatable shaft; and
wherein the tine exhibits a lean, such that the tine forms an angle of 0.5°
to 15°

Abstract
A tine for mounting on a rotatable shaft of soil aeration and cultivation equipment, comprising: mounting means at an attachment end of the tine; a tip at a ground-engaging end of the tine opposite the attachment end; leading and trailing convex curvilinear edges disposed opposite each other and converging toward the attachment end and the tip; and bevelled sections on each of the leading and trailing convex curvilinear edges. The unique shape of the tine has been found to create a wider range of soil disturbance than is the case with conventional straight-edge tines, requires less material to manufacture, and penetrates the ground surface more easily than conventional straight-edge tines due to the convex leading edge.
