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.

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.

A seed meter disk includes a body defining a plane of rotation. A circumferential array of seed openings are provided for seed adherence. A circumferential array of seed agitator pockets are formed as depressions in the first side of the body, each one of the array of seed agitator pockets having a radially inner end, a radially outer end, and a trailing edge extending from the radially inner end to the radially outer end. At least a portion of the trailing edge of one or more of the seed agitator pockets is backswept so that a circumferential-direction offset from a radial reference line rotationally ahead of the trailing edge, with respect to rotation of the seed meter disk in an operational direction, increases toward the radially outer end. The backswept portion is non-linear.

An agricultural vehicle includes a coupling structure for making a tool-less attachment between a first connector piece and a second connector piece. The first connector piece has at least one pin, and the second connector piece has at least one slot adapted to receive the pin in a receiving pocket that is circumferentially spaced from an axially-open inlet portion of the slot. The slot includes an inlet ramp between the slot inlet portion and the receiving pocket, and the inlet ramp is less steeply angled than a second ramp surface that forms a portion of the receiving pocket adjacent the first ramp.

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.

A system for electronically pulsing agricultural product with seed. A seed transport mechanism is affixed to a seed planter row unit having a seed metering system, operating at a high speed configured to dispense seed. The seed transport mechanism is configured to provide a seed release speed at which the seed and agricultural product exit the seed transport mechanism, the seed release speed being varied in a manner proportional to the variation in the ground speed of the seed planter row unit to minimize seed tumbling to optimize accurate placement of seed and chemical granule agricultural product at varying ground speeds of the seed planter row unit. In the various embodiments, the agricultural product is directed away from moving parts after the seed leaves the seed metering system of the seed planter row unit.

Systems, methods and apparatus are disclosed for selecting an agricultural input. First and second seed meters selectively meter seed from first and second sources, respectively, into a common planting trench. In some embodiments the seed meters are selectively operated by electric motors controlled with reference to a seed type prescription. In some embodiments the first and second seed meters deposit seeds along a common plane.

Described herein are methods and systems for planting seed. A system includes a row unit configured to open a planting trench. A first seed meter has a first coding scheme and receives a first seed type from a first hopper having the first coding scheme. A second meter has a second coding scheme and receives a second seed type from a second hopper having the second coding scheme.

Meters for fertilizers, small seeds, and chemicals include a housing defining a loading chamber, a rotatable metering disk provided with a receiving surface and a discharge surface, the disk including metering orifices; a ring including a discharge opening, and an insulating barrier arranged in the interior of the housing, the insulation barrier forming an insulating chamber on the rotatable disk and defining an inlet region of the disk and an output region of the disk; a metering bulkhead associated with the insulating barrier in the inlet region of the rotating disk with metering orifices loaded, the metering bulkhead being arranged on the rotatable metering disk so that a lower portion of the metering bulkhead is coplanar to the receiving surface of the rotatable disk.
