Abstract
Systems, methods and apparatus for adjusting the depth of a trench opened by a row unit of an agricultural planter. The row unit includes a trench depth adjustment assembly configured to modify the furrow depth. A first depth adjustment sub-assembly is configured to select one of a plurality of pre-selected furrow depths. A second adjustment sub-assembly is configured to modify at least one of a plurality of the pre-selected furrow depths.
Claims21
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, comprising:
- a first depth adjustment sub-assembly defining pre-set positions in which a depth adjustment body is selectively positionable such that said depth adjustment body limits an amount of upward displacement of said gauge wheel with respect to said furrow opening disc;
- a second depth adjustment sub-assembly operable to modify a position of said depth adjustment body from one of said pre-set positions set by said first depth adjustment sub-assembly so as to further adjust an amount of upward displacement of said gauge wheel with respect to said furrow opening disc.
