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 and latch lid.

Hose pinched or crushed.

Replace or repair hose.

Foreign material blocking air system.

Remove hose by pulling straight off (do not twist) from nozzle to remove material causing plug. See BRIDGED AND BLOCKED CCS SYSTEM in Pro-Series XP Central Commodity System section.

Hoses routed flat or uphill or have large droops.

Reroute 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 fan off if 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.

If required for seed used, make sure that grey discharge elbows are installed properly on 36 row and larger machines. See OPERATING CCS SYSTEM WHEN PLANTING STANDARD SEED SIZES in Pro-Series XP Central Commodity System.

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. See BRIDGED AND BLOCKED CCS SYSTEM in Pro-Series XP Central Commodity System section.

Blockage in nozzle.

See BRIDGED AND BLOCKED CCS SYSTEM in Pro-Series XP Central Commodity System section.

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 or 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 and can cause seed to pack into nozzles.

Nozzle inserts installed on nozzles for planting sorghum.

Remove nozzle inserts when not planting sorghum.

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.

Nozzle blockage inside tank.

With parking brake engaged, transmission in park and tractor off, remove outlet air hose from tank. Check for obstruction and remove if found.

Seed compacted in tank 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 mini hopper.

Clear plug and decrease CCS tank pressure.

If required for seed used, make sure that grey discharge elbows are installed properly on 36 row and larger machines. See OPERATING CCS SYSTEM WHEN PLANTING STANDARD SEED SIZES in Pro-Series XP Central Commodity System section.

Seed bridging in CCS tank.

Check if agitator is running. Check fuse, power connector, and ground lead. See BRIDGED AND BLOCKED CCS SYSTEM in Pro-Series XP Central Commodity System section.

Increase CCS tank pressure.

Add and thoroughly mix John Deere talc lubricant with seed.

CCS tanks empty.

Fill CCS tanks.

Nozzle inserts installed.

Remove nozzle inserts when planting other crops.

Reduce CCS tank pressure.

Add talc.

Old, dry seeds.

Use fresh seeds.

Fill or redistribute seed in CCS tanks.

Meter vacuum level too high.

Decrease vacuum level.

Vacuum hopper vent plugged.

Clean vent.

Discharge elbow vent plugged.

Clean vent holes in elbow.

Increase CCS tank pressure.

Foreign material blocking product passages.

Remove blockage. See BRIDGED AND BLOCKED CCS SYSTEM in Pro-Series XP Central Commodity System section.

Hopper screen plugged.

Remove screen and tap until clear.

Lumps in seed.

Use clean seed. Use screens when filling tanks.

Seed bridging in tank.

See BRIDGED AND BLOCKED CCS SYSTEM in Pro-Series XP Central Commodity System section.

Increase CCS tank pressure.

Add and thoroughly mix John Deere talc lubricant with seed.

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. See BRIDGED AND BLOCKED CCS SYSTEM in Pro-Series XP Central Commodity System section.

Do not operate machine with nearly all meters out of seed as the seed hoses to rows with seed can plug. See BRIDGED AND BLOCKED CCS SYSTEM in Pro-Series XP Central Commodity System section.

Adjust CCS fan pressure to recommended level.

Cold hydraulic oil.

Run CCS fan 10 minutes before planting to warm oil. Set tank pressure.

Replace valve.

Adjust frame height.

Adjust row unit fan switch.

Row unit fan switch not functioning.

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

Foreign material is lodged in hose or manifold.

See BRIDGED AND BLOCKED CCS SYSTEM in Pro-Series XP Central Commodity System section.

Improper tank pressure.

Install lids.

Readjust SCV flow setting.

Increase CCS tank pressure by 2 in.

Clean sensor LEDs with a brush.

Tank low warning light burned out.

To test, unplug all tank level sensor harness connectors. If light does not come on, replace light inside frame control box.
