Patent ID: 6945332

Claim:
An aeration tine device attached to a soil aerator, comprising: a tubular tine member extending along an axial direction thereof between a lower end portion and an upper end portion and having a lower opening bored at a center of a lower end surface, and a side ejection opening in communication with the lower opening, the lower end surface extending in a plane perpendicular to the axial direction; a metal tip having a tapered distal end portion formed with a tip opening and a proximal end portion formed with a proximal opening bored at a center of a proximal end surface in communication with the tip opening, the proximal end surface extending in a plane perpendicular to the axial direction and coupling in an area in contact with the lower end surface of the tubular tine member; and a ring-shaped metal foil insert between the lower end surface of the tubular tine member and the proximal end surface of the metal tip in a plane perpendicular to the axial direction of the tine member for connecting the tubular tine member with the metal tip by brazing.
