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.

1. An agricultural row unit assembly comprising: an attachment frame configured for attachment to a tow bar movable in a direction of travel;a swing-arm having a proximal end and a distal end, the proximal end being coupled to the attachment frame;an opener disk mounted to and offset from the distal end of the swing-arm for forming a furrow, the opener disk being configured to rotate about a first axis relative to the direction of travel;a deflecting disk mounted to the distal end of the swing-arm for deflecting debris from entering the furrow, the deflecting disk being mounted between the distal end of the swing-arm and the opener disk, the deflecting disk being configured to rotate about a second axis relative to the direction of travel, the second axis being different than the first axis; anda closing wheel coupled to the attachment frame for closing the furrow. 2. The agricultural row unit assembly of claim 1, wherein the deflecting disk has a bottom peripheral edge that is positioned above the furrow. 3. The agricultural row unit assembly of claim 1, wherein the first axis is angled relative to the second axis such that respective top peripheral edges of the opener disk and the deflecting disk are separated by a greater top distance than respective bottom peripheral edges of the opener disk and the deflecting disk. 4. The agricultural row unit assembly of claim 1, wherein the first axis is at an oblique angle relative to the direction of travel and the second axis is generally perpendicular relative to the direction of travel. 5. The agricultural row unit assembly of claim 1, further comprising a closing-wheel arm connecting the closing wheel to the swing-arm. 6. The agricultural row unit assembly of claim 5, wherein the closing-wheel arm is curved upwards to avoid physical interference with at least one of the opener disk and the deflecting disk. 7. The agricultural row unit assembly of claim 1, wherein the closing wheel is selected from a group consisting of toothed wheels and smooth wheels. 8. The agricultural row unit assembly of claim 1, further comprising a parallel linkage, the closing wheel being connected to the attachment frame via the parallel linkage, the closing wheel being movable independently of the opener disk and the deflecting disk. 9. The agricultural row unit assembly of claim 1, wherein the attachment frame is a rigid immovable frame. 10. The agricultural row unit assembly of claim 1, wherein the attachment frame is a parallel linkage. 11. An agricultural row unit assembly comprising: an attachment frame configured for attachment to a tow bar movable in a generally horizontal direction of travel;a swing-arm having a proximal end and a distal end, the proximal end being coupled to the attachment frame;an opener disk for forming a furrow and mounted to the distal end of the swing-arm, the opener disk being mounted in an offset internal position relative to the distal end, the opener disk having a top peripheral edge positioned above the distal end, the opener disk having a bottom peripheral edge positioned below the distal end and within the furrow, the opener disk being rotatable about a first axis;a deflecting disk mounted to the distal end of the swing-arm between the opener disk and the distal end, the deflecting disk having a top peripheral edge positioned above the distal end, the deflecting disk having a bottom peripheral edge positioned below the distal end and above the furrow, the deflecting disk being rotatable about a second axis that is different than the first axis;a closing-wheel arm coupled to the attachment frame; anda closing wheel connected to the closing-wheel arm for closing the furrow. 12. The agricultural row unit assembly of claim 11, wherein at least one of the first axis and the second axis is at an oblique angle relative to the direction of travel. 13. The agricultural row unit assembly of claim 11, wherein one of the first axis and the second axis is at a generally perpendicular angle relative to the direction of travel. 14. The agricultural row unit assembly of claim 11, wherein the closing-wheel arm is curved upwards to avoid physical interference with at least one of the opener disk and the deflecting disk. 15. The agricultural row unit assembly of claim 11, wherein the closing wheel is selected from a group consisting of toothed wheels and smooth wheels. 16. The agricultural row unit assembly of claim 11, further comprising a parallel linkage, the closing-wheel arm being coupled to the attachment frame via the parallel linkage, the closing wheel being movable independently of the opener disk and the deflecting disk. 17. The agricultural row unit assembly of claim 11, wherein the closing-wheel arm is coupled to the attachment frame via the swing-arm. 18. The agricultural row unit assembly of claim 11, wherein the attachment frame is a rigid immovable frame. 19. The agricultural row unit assembly of claim 11, wherein the attachment frame is a parallel linkage. 20. The agricultural row unit assembly of claim 11, further comprising a gauge wheel attached to the swing-arm via a gauge-wheel arm such that a leading edge of the gauge wheel is located rearwardly of a trailing edge of the opener disk.
