A furrow opener comprises an opener body including a shank mount arranged to support the opener body on an agricultural implement shank for movement in a forward working direction and a tip body readily separable from the opener body and arranged for forming a furrow in the ground in the working direction. The tip body includes a furrowing portion extending downwardly and forwardly beyond the opener body so as to be arranged to form the furrow in the ground. A retainer member is supported on the opener body to retain a portion of the tip body adjacent the top end thereof on the opener body to provide support to the tip body against a moment acting on the tip body from the rearward force on the furrowing portion during furrow formation.
