A pneumatic seed delivery system is provided for use with planter for row-crop planting an agricultural field in which the pneumatic seed delivery system may use high pressure air to accelerate seeds that are singulated from a seed meter to match ground speed when planting. The pneumatic seed delivery system includes an air accelerator arranged downstream of a release location of the seed meter. The air accelerator may define a pneumatic device such as an air conveyor or air amplifier that merges a primary airflow with a controllable supplemental airflow to provide a correspondingly controllable combined airflow that carries and accelerates the singulated seeds so that the seeds can be released with a rearward horizontal seed velocity component that approximates a forward ground speed of the planter to reduce seed tumble.

An agricultural metering system includes a metering system component, and the metering system component includes a substrate formed from a polymeric material. The metering system component further includes a coating disposed on the polymeric material of the substrate, in which the coating includes a metallic coating and/or a ceramic coating.

A flow control insert for an agricultural metering system includes a body configured to couple the flow control insert to a housing of the agricultural metering system. The flow control insert also includes a shoulder extending from the body. The shoulder is configured to engage a channel in a meter roller to control flow of particulate material within the channel along a rotational direction of the meter roller.

A seeding element including a tank configured to contain seeds, at least one planting device and at least one dispensing housing delivering the seeds, one by one, via a rotary dosing element, the seeds being dispensed pneumatically. A pneumatic single-grain seeder can include at least one of the seeding element.

A method including adjusting a changeable component of a seed planting machine when switching from a first variety of seed to a second variety of seed during planting, wherein the adjusting is based on a location of the planting machine.

A seed meter for an agricultural planter in which the seed disc is rotatably mounted within a seed meter housing. As the seed disc rotates, the apertures in the disc rotate along a seed aperture path through a horizontally adjacent seed pool area. The seed disc includes cavities disposed along the seed aperture path to agitate the seeds in the seed pool area. A singulator having multiple co-planar singulator surfaces is biased against the seed side surface of the seed disc.

A multiple variety seed meter for multi-variety row crop planting includes a segmented sump that may have an active sump segment and an inactive sump segment. A seed switching arrangement is used to select which seed variety is available in the active sump segment for exposure to a seed disk for singulation by a seed disk for delivery onto the agricultural field while planting.

The flow control insert also includes a shoulder extending from the body. The shoulder is configured to engage a channel in a meter roller to control flow of particulate material within the channel along a rotational direction of the meter roller.
