摘要:
A furrow opener on an agricultural ground working implement has an opener body supported on a tool supporting shank of the implement and a replaceable furrowing tip body on the opener body. A delivery passage extends through the opener body and the tip body to deposit granular material in a furrow formed in the ground by the furrow opener. The tip body has a vertical knife portion and laterally protruding wings. Each wing further includes a soil shield portion projecting upwardly from the inner edge of the respective wing alongside the corresponding side surface of the opener body so as to resist penetration of soil into the chamber through a seam between the inner edge of the wing and the corresponding side surface of the opener body.
