Abstract

An agricultural row unit assembly includes an attachment frame, a swing-arm, an opener disk, a deflecting disk, a support, a gauge wheel, and a ground-hardness sensor. The opener disk is mounted to and offset from the distal end of the swing-arm for forming a furrow, and is configured to rotate about a first axis. The deflecting disk is mounted to the distal end of the swing-arm for deflecting debris from entering the furrow, and is configured to rotate about a second axis. The support has a first end pivotably mounted to the swing-arm and a second end movable relative to the opener disk. The gauge wheel is mounted to the second end of the support. The ground-hardness sensor is disposed within the swing-arm and is configured to detect movement of the gauge wheel relative to the opener disk.

Dependent claims

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 configured to rotate about a second axis relative to the direction of travel, the second axis being different than the first axis;
a support having a first end pivotably mounted to the swing-arm and a second end movable relative to the opener disk;
a gauge wheel mounted to the second end of the support;
and
a ground-hardness sensor disposed within the swing-arm and configured to detect movement of the gauge wheel relative to the opener disk.
