Continuous seed metering system

摘要

A device for planting different varieties of seeds is provided with a seed hopper or carousel that is selectively placed in open communication with a plurality of seed metering devices. A selectively positionable gate member directs the seeds to specific seed metering devices. The seed metering devices are movable on the device to engage a first metering device with a ground engagement assembly and a second metering device with a discharge container. The seed metering devices operate in alternating seed-dispersing and clearing modes simultaneously to speed planting. A GPS system may be incorporated to track and accurately control the planting operation.
