A - Delivery Hose

Seed treatments, field conditions, humidity, and seed size alters CCS pressures required to deliver seed to all rows. Talc lubrication is required on ALL crops to lubricate seed. Chemically treated seed can require two to three times the rate of lubrication to avoid plugging. When changing crops, use the initial setting found in SETTING CCS TANK PRESSURE in this section before adjusting for field conditions.

Generally, the CCS system performs best when using the lowest possible pressure setting to deliver seed to all row units.

Some light weight varieties of seed, such as sorghum-milo, are picked up to easily by the nozzles. Nozzle inserts are installed over the nozzles to restrict the opening slightly, limiting the amount of seed a nozzle picks up. Nozzle inserts allow light weight seeds to flow at optimum rates and reasonable pressures ensuring reliable seed delivery to all rows.

IMPORTANT: Avoid hydraulic motor and tank lid damage. DO NOT exceed 24 in. of tank pressure.

Random drops in population that last only short periods (5—20 seconds) can indicate the CCS system is not maintaining adequate seed flow.

Make sure meters and vacuum system is functioning properly before adjusting CCS system.

Increase CCS pressure in 2 inch increments until random population drops stop.

If monitor issues a “Row Failed” warning, first determine if the failure is caused by bridging or plugging.
