Agricultural apparatus with hybrid single-disk, double-disk coulter arrangement

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;
• and
• a closing wheel connected to the closing-wheel arm for closing the furrow.
