CCS Description

The metering of seeds on the CCS acts a conductor for each row unit; it always provides a small quantity of seeds in each row unit to feed the meter.

The CCS seed metering system has one tank on machines with 18 rows or less and two tanks on machines with 20 rows or more, centrally located for easy filling. Inside the seed tanks there is an agitating shaft that prevents the seeds from compacting at the bottom of the tank.

A hydraulically driven impeller supplies the flow of air that is necessary to meter the seeds. A space inside the tank support structure distributes the flow of air to pressurize the tanks.

The lower section of the tank contains a manifold. The manifold has a cup for each row unit that pulls the seed in with the airflow and delivers it to the row unit feeder. Inside the row unit feeder there is an entry elbow that acts as an on/off mechanism for seed metering.

The flow of seeds is cut when the level of seeds reaches to lower part of the elbow inside the feeder. The flow of air is not sufficient to overcome this obstacle and so the metering process is halted. The seeds continue to be metered by a meter on the row unit, ensuring precise and constant seed spacing.
