A seeder comprises a front furrow opener forming a first furrow and a rear furrow opener forming a second furrow beside the first furrow. The rear furrow opener has a ground engaging front face oriented at an angle to the operating travel direction such that a far side of the face, farthest from the first furrow, is ahead of an opposite near side of the face such that soil engaged by the face is pushed toward the first furrow, and the rear furrow opener tends to move away from the first furrow. A membrane between the paired shanks of the furrow openers facilitates trash flow and reduces trash build up on the rear shank.
