Abstract: A planter row unit is disclosed having an active downforce control system for the closing wheels. This separate control of the downforce pressure for the closing wheels is provided from the row unit downforce control. A single operator input is used to set a desired downforce for all row units. The control system then operates to produce the desired downforce. Alternatively, the control system may display a downforce load to the operator who then manually makes adjustments as desired.

Abstract: The present invention provides a monitor of the hose connection of a pneumatic product-on-demand delivery system in an agricultural machine. This can be done in several ways. One way is to sense the product flow in the product hose and how long it is running. If the product is constantly running through the hose, that indicates a disconnection. A second way is to sense air pressure in the product hose to determine if it is still operating under pressure. If disconnected, the air pressure will drop indicating a disconnection. A third way is to sense a current through the connection to determine if it is on or off. All of these methods produce a signal that can be fed back to a monitor at the operator station and give the operator an alert if a disconnected hose is detected.

Abstract: A detector is supported adjacent the seed cells within a seed meter housing and provides an indication of the presence or absence of seeds in the cells. A processor receives the seed presence indications and provides an operator readout to facilitate adjustments to the seed meter system to maintain a single seed per seed cell at the given seed population. In one embodiment, the detector is a video camera and the readout includes a slow motion rendering of the seed cells downstream of a seed singulator. In another embodiment, a light source is located on one side of the seed cells, and a light detector is located on the opposite side of the seed cell to determine presence or absence of material in the cell.
