Agricultural apparatus with hybrid single-disk, double-disk coulter arrangement
First Claim
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; and
a closing wheel coupled to the attachment frame for closing the furrow.

Abstract
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.

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; and a closing wheel connected to the closing-wheel arm for closing the furrow. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
