An agricultural row unit assembly includes an attachment frame configured for attachment to a tow bar that is movable in a direction of travel. A proximal end of a swing-arm is coupled to the attachment frame, and an opener disk is mounted to and offset from a distal end of the swing-arm for forming a furrow. The opener disk is configured to rotate about a first axis relative to the direction of travel. A deflecting disk is mounted to the distal end for deflecting debris from entering the furrow, and is mounted between the distal end of the swing-arm and the opener disk. The deflecting disk is configured to rotate about a second axis, which is different than the first axis, relative to the direction of travel. A closing wheel is coupled to the attachment frame for closing the furrow.
