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, said depth adjustment body disposed to engage said gauge wheel arm to limit an amount of upward travel of said gauge wheel with respect to said furrow opening disc; a motor operable to cause rotation of a shaft, said shaft operably coupled with said depth adjustment body, whereby rotation of said shaft causes said depth adjustment body to pivotally move about said pivot thereby changing a position of contact of said depth adjustment body with said gauge wheel arm thus changing the amount of upward travel of said gauge wheel with respect to said furrow opening disc; characterized in that said shaft is rotationally fixed to a cable drum, a cable is attached at one end to said cable drum and said cable is linked at another end to said depth adjustment body. 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, said depth adjustment body disposed to engage said gauge wheel arm to limit an amount of upward travel of said gauge wheel with respect to said furrow opening disc; a motor operable to cause rotation of a shaft, said shaft operably coupled with said depth adjustment body, whereby rotation of said shaft causes said depth adjustment body to pivotally move about said pivot thereby changing a position of contact of said depth adjustment body with said gauge wheel arm thus changing the amount of upward travel of said gauge wheel with respect to said furrow opening disc; a depth adjustment body pivotally connected via a pivot to said row unit frame, said depth adjustment body disposed to engage said gauge wheel arm to limit an amount of upward travel of said gauge wheel with respect to said furrow opening disc; a motor operable to cause rotation of a shaft, said shaft operably coupled with said depth adjustment body, whereby rotation of said shaft causes said depth adjustment body to pivotally move about said pivot thereby changing a position of contact of said depth adjustment body with said gauge wheel arm thus changing the amount of upward travel of said gauge wheel with respect to said furrow opening disc; characterized in that said shaft is rotationally fixed to a cable drum, a cable is attached at one end to said cable drum and said cable is linked at another end to said depth adjustment body.
