Abstract: A seed meter includes a meter housing having a first chamber for seeds and a second chamber. A seed disk is rotatably supported within the meter housing and has a first side and a second side. The first side is exposed to the first chamber and the second side is exposed to the second chamber. The seed disk includes a plurality of seed openings that extend between the first and second sides at a predetermined radial position. A singulator is positioned against the first side of the seed disk and has at least one structure for removing excess seeds from the seed openings as the seed meter disk rotates relative to the singulator. A radial position of the singulator is controlled at least in part by a hub portion of the seed meter. A biasing spring is positioned to exert an axially-oriented bias force pressing the singulator against the first side of the seed meter disk.

Abstract: A row unit for a seeding machine includes a seed reservoir and a seed meter having a metering member configured to rotate about an axis. The metering member has a seed side facing the seed reservoir, a non-seed side opposite the seed side, and a plurality of apertures. The axis is normal to a surface of the seed side. The seed meter is operable by pressure differential between the non-seed side and the seed side to adhere seeds to the seed side and move seeds from the seed reservoir. The row unit also includes a positive pressure air source and an air outlet fluidly coupled to the positive pressure air source. The air outlet is disposed on the seed side and aimed to discharge an air stream towards one aperture of the plurality of apertures. The dischargeable air stream has a directional component parallel to the axis.

Abstract: A seed metering system for metering a plurality of seeds includes a meter housing having a first side and a second side. A seed inlet is positioned at the first side and an aperture is positioned at the second side. The seed metering system further includes a hub mounted within the aperture, a retaining member located at the hub, and a metering member positioned on the hub. The metering member compressively engages the retaining member.

Abstract: A method includes performing a plurality of calibration routines in which a metering element operates at different speeds. The method also includes receiving a respective plurality of measurements of commodity amounts metered out during the calibration routines. The method further includes generating a calibration factor for operating the metering element based on data generated from the measurements taken from the calibration routines. Also, the method includes generating a control command for the metering element according to the calibration factor. The method additionally includes operating, by the control system, the metering element according to the control command.

Abstract: A seed sensor includes a housing. An internal seed channel defines a path for seeds to flow along a central axis through the seed sensor. A sensor unit is positioned alongside the internal seed channel within the housing. An inlet end of the seed sensor includes a tapered inlet section. The housing includes a mounting loop having a pair of oppositely angled surfaces for mounting the seed sensor in a pair of oppositely angled configurations.

Abstract: A seed receptacle includes a housing defining a seed chamber within, a seed inlet formed in the housing, a seed outlet formed in the housing, and an air inlet separate from the seed inlet and mounted to the housing. The air inlet includes a first end attached to the housing and defining a first aperture, a second end, opposite the first end and defining a second aperture, and a channel defining an airflow path between the first end and the second end. The air inlet has an elasticity and a weight such that the second end sags relative to the first end.

Abstract: A method of operating a volumetric metering system for a work vehicle includes detecting, with a sensor as the work vehicle moves, a tilt condition of the volumetric metering system relative to a reference horizontal plane. The method also includes generating, by a processor, a control command for a metering element based, at least partly, on the detected tilt condition. Furthermore, the method includes varying an actuation speed of the metering element according to the control command. A system for this method is also disclosed.
