ABSTRACT:
A highly durable aeration tine device attached to a soil aerator has a tubular tine member extending cylindrically and a hard metal tip made of a hard metal material and typically made in a frustum shape of a cone, which is in an area contact with the tubular tine member between the surfaces of the tubular tine member and the hard metal tip. Each surface of the tubular tine member and the hard metal tip is extending in a plane perpendicular to the axial direction and can be fabricated easily, and the drive force provided from the soil aerator can be transmitted without loss.
