CCS Product Delivery

Plugged delivery hoses.

Foreign material in seed.

Clean seed or use lid screen.

Tank lids were opened with CCS fan running.

Wait till CCS fan is stopped 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.

Reroute hoses correctly.

High humidity.

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

Uneven product distribution between row units.

Product level too low for accurate delivery.

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.

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

Covers installed on nozzles for planting sorghum.

Remove covers when not planting sorghum.

Tanks don't empty out evenly.

Machines with odd number of rows, more rows are consuming seed from one tank than the other.

No solution.

AG,OUO6023,1198 -19-21JUL00-2/5

No seed in meter.

Air volume too low.

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 starting by meter and working up towards tank. Increase tank pressure to 16 in. if necessary as seed will blow 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.

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

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.

Plugged inlet elbow entering mini hopper.

Clear plug and decrease CCS tank pressure.

Seed bridging in CCS tank.

Increase CCS tank pressure.

CCS tanks empty.

Fill CCS tanks.

Covers installed on nozzles for planting sorghum.

Remove covers when planting other crops.

AG,OUO6023,1198 -19-21JUL00-3/5

Seed damage.

Air volume too high.

Reduce CCS tank pressure.

Add talc.

Old, dry seeds.

Use fresh seeds.

Individual rows overpopulating.

CCS tanks running empty.

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.

Uneven/Inaccurate metering or product delivery.

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 and remove if found.

Hopper screen plugged.

Remove screen and tap until clear.

Lumps in seed.

Use clean seed. Use screens when filling tanks.

Seed bridging in tank.

Increase CCS tank pressure.

Add and thoroughly mix John Deere talc lubricant for vacuum meters, or graphite for radial bean and finger pick-up meters to seed tank.

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.

AG,OUO6023,1198 -19-21JUL00-4/5

No seed flow.

Plugged seed delivery hose.

Do not raise and lower machine continuously without planting seed. Excessive fan stopping and starting without planting will lead to plugs.

Do not operate machine with nearly all meters out of seed as the seed hoses to rows with seed will 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.

CCS fan surges.

Faulty flow control valve.

Replace valve.

Slow lower time on machine.

CCS fan is running during lower cycle.

Row unit switch not functioning.

CCS seed delivery flow is low.

Seed hose is pinched.

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

Foreign material may be lodged in hose or manifold.

Locate and remove foreign material blockage.

Improper tank pressure.

Install lids.

Readjust SCV.

Increase CCS tank pressure by 2 in. of H2O.
