Abstract
A paired row opener has a furrowing tip arranged to be selectively supported on a body of the opener. The furrowing tip includes a knife portion and a pair of wing portions extending rearwardly and outwardly therefrom. A central chamber between the wing portions communicates with a primary delivery passage of the opener body to receive the primary particulate material therefrom to be dispensed in a paired row from a pair of outlet openings of the chamber which are laterally spaced apart in a rear face of the tip body. A bottom wall spans a bottom side of the chamber between the wing portions to the rear face such that the outlet openings lie in an upright plane at a rearmost end of the tip body to be prevented from plugging even in wet conditions, while remaining selectively separable with the tip body from the opener body for replacement.
