Clean seed or use lid screen.

Tank lids were opened with CCS fan running.

Wait until CCS fan stops before opening lids.

Excessive CCS fan pressure.

Reduce pressure.

Tank lid open or leaking excessively.

Close lid, empty hose line.

Hose pinched or crushed.

Replace or repair hose.

Air volume too low.

Increase CCS fan speed. See SETTING CCS TANK PRESSURE in Central Commodity System section.

Foreign material blocking air system.

Remove hose by pulling straight off (do not twist) from nozzle to remove material causing plug.

Hoses routed flat or uphill or have large droops.

Route hoses correctly.

High humidity.

Use more talc and mix thoroughly or wait for drier conditions.

CCS fan running while not planting for excessive period of time.

Turn off fan, when not planting for more than a few minutes.

CCS nozzle must be covered to deliver seed.

Hopper screen plugged.

Remove screen and tap until clear.

Discharge elbow plugged.

Remove elbow and clean.

Air volume too low.

Increase CCS tank pressure. See SETTING CCS TANK PRESSURE in Central Commodity System section.

Blockage in air hose.

Clear air hose.

Blockage in nozzle.

Shut off CCS fan. Remove delivery hose by pulling straight off (do not twist) nozzle and remove material.

Seed compacted in tank nozzles.

See BRIDGED AND BLOCKED CCS SYSTEM in Central Commodity System section.

Nozzle inserts installed on nozzles for planting small seed.

Remove nozzle inserts when not planting small seed.

Agitator not running.

Check fuse, power connector, and ground lead.

Verify tank pressure is set to recommended pressure.

Blockage in air hose.

Cleanout meter using tray. Reinstall seed disc and close vacuum dome. Start CCS fan and shake hose vigorously near meter. Continue shaking hose closer and closer to tank. Increase tank pressure, if necessary to blow seed out easier. If meter fills with seed, repeat process until no more seed is in hose.

Check that both tank lids are securely closed.

Blockage in nozzle inside tank.

Engage tractor parking brake, put transmission in park, shut off tractor, and remove outlet delivery hose from CCS tank. Check for obstruction. Remove any obstruction. Reconnect seed delivery hose.

Seed compacted in tank nozzles.

Shut off tractor, engage park brake and remove outlet delivery hose from CCS tank (pull straight off—do not twist). Loosen and remove seed stuck in nozzle. Whenever planter is lowered and stationary for more than a few minutes with seed in CCS tank, shut off tractor and turn key off. Agitators run anytime planter is lowered and key is on. This causes seed to pack into nozzles.

High humidity.

Use more talc and mix thoroughly or wait for drier conditions.

CCS tank lid open.

Close lid.

Cleanout doors on bottom of tank are open or leaking air.

Close doors.

Discharge elbow plugged in hopper.

Clear plug and decrease CCS tank pressure.

Seed bridging in CCS tank.

Check if agitator is running. Check fuse, power connection, and ground lead.

Increase CCS tank pressure.

Add more talc and mix thoroughly.

CCS tanks empty.

Fill CCS tanks.

Nozzle inserts installed on nozzles for planting small seed.

Remove nozzle inserts when planting other crops.

Reduce CCS tank pressure.

Add talc.

Old, dry seeds.

Use fresh seeds.

Decrease vacuum level.

Vacuum hopper vent plugged.

Clean vent.

Discharge elbow vent plugged.

Clean vent holes in elbow.

Fill or redistribute seed in CCS tanks.

Product level in seed meter too low for accurate delivery.

Increase CCS tank pressure.

Foreign material blocking product passages.

Remove blockage. Use screens when filling tanks.

With parking brake engaged, transmission in park and tractor off, remove outlet air hose from tank. Check for obstruction. Remove any obstruction. Reconnect seed delivery hose.

Hopper screen plugged.

Remove screen and tap until clear.

Lumps in seed.

Use clean seed. Use screens when filling tanks.

Seed bridging in tank.

Check if agitator is running. Check fuse, power connection, and ground lead.

Increase CCS tank pressure.

Add more talc and mix thoroughly.

Rubber flap on meter not covering the seed tube opening in the shank.

Realign rubber flap to sit flat on row unit when meter is installed.

Do not raise and lower machine continuously without planting seed. Excessive fan stopping and starting without planting, plugs seed delivery hoses.

Do not operate machine with nearly all meters out of seed as the seed hoses to rows with seed can plug. Stop and fill machine once the first row runs out of seed.

Adjust CCS fan pressure to recommended level.

Cold hydraulic oil.

Allow tractor to warm before setting tank pressure.

Replace valve.

Adjust frame height.

Adjust row unit fan switch. See SETTING CCS ROW UNIT SWITCH in Service as Required section.

Adjust row unit fan switch.

Verify CCS Plant/Purge switch is in the Pant/Tank Cleanout position.

Straighten or repair hose. Keep hoses as horizontal as possible.

Foreign material is lodged in hose or manifold.

Locate and remove foreign material blockage.

Improper tank pressure.

Ensure tank lids are installed correctly.

Readjust SCV.

Increase CCS tank pressure by 2 in. of pressure.
