Patent attributes
A variable rate air metering system is provided. The system includes seed meter cartridges, each having a housing, a meter wheel, and a variable speed electric motor operatively connected to the seed meter cartridge. The seed meter cartridges provide flowable material to distribution manifolds, which are configured to distribute flowable material to multiple row outputs for deposition into a field. A control system is configured to control operation of the distribution manifolds for enabling/disabling dispersement of flowable material to row units. The control system is also configured to adjust the dispersement rate of flowable material by the seed meter cartridges in association with the opening/disabling the dispersement of flowable material to row outputs.
