Claim 17:
18. An agricultural row unit, comprising:
a row unit frame;
a furrow opening disc rotatably supported by said row unit frame for opening a furrow in a soil surface as the row unit frame advances in a forward direction of travel;
a gauge wheel disposed adjacent to said furrow opening disc and pivotably supported from said row unit frame by a gauge wheel arm such that said gauge wheel is displaceable with respect to said furrow opening disc;
a depth adjustment assembly, including:
a depth adjustment body pivotally connected via a pivot to said row unit frame;
a gear rack disposed on said row unit frame;
a gear box connected to said depth adjustment body;
a homing system comprising a sensor and a target, wherein said sensor is disposed on said gear box, and said target is disposed on said gear rack, and wherein said sensor senses said target as said sensor passes in proximity to said target; and
an electric motor operably coupled to drive a gear of said gear box in engagement with said gear rack;

whereby driving said gear in engagement with said gear rack by said electric motor adjustably positions said depth adjustment body with respect to said gear rack to control a depth of the furrow opened by the furrow opening disc by limiting an amount of upward travel of said gauge wheel arm with respect to said furrow opening disc.
