Abstract: Systems, methods and apparatus are provided for determining the depth of a trench opened by an agricultural planter. Sensors are provided for detecting the position of a ground-engaging element of the planter such as a gauge wheel or seed firmer of a row unit of the planter. Apparatus and methods are provided for installing such sensors onto a row unit of the planter. Systems, methods and apparatus are provided for controlling downpressure on a row unit based on the trench depth. Methods are provided for mapping trench depth measured by the depth sensors.

Abstract: A downforce controller for an agricultural implement having a double-acting hydraulic cylinder. The cylinder is configured to be coupled to an agricultural row unit and an agricultural toolbar for transmitting a net downforce between the agricultural toolbar and the agricultural row unit. A first pressure in the first chamber of the cylinder and a second pressure in the second chamber of the cylinder having counteracting effects on the net downforce. A manifold coupled to the cylinder is in fluid communication with the first chamber. A pressure control valve supported by the manifold is in fluid communication with the manifold and the first chamber.

Abstract: A row unit for an agricultural planter having features for releasably operably coupling a seed meter of the row unit to a seed deposition apparatus of the row unit such as a seed conveyor, seed tube or the like. Apparatus are provided for tipping a seed meter of the hopper for disengagement from the seed deposition apparatus. Apparatus are provided for biasing the seed deposition apparatus into operative engagement with the seed meter. The row unit includes features such as latches for releasably operably coupling the row unit to crop input and vacuum supply lines. Apparatus are provided for tipping a seed meter of the hopper for disengagement from the crop input and vacuum supply lines. Systems are provided for supplying vacuum and crop inputs to the seed meter via the releasably engageable apparatus.
