JD 7000 FF wings planting less population

[Farm1447]

I just installed a 20/20 system on my JD 7000 FF 12 row.  Both 3 row wings are planting 13% less than the center 6 rows.  This is driving the 20/20 system to sound alarms.  Has anyone had this problem?

I'm not a planter expert by any means, but I'd start by unbolting the JD planter from the 20/20 system and replace it with something red, lets just say CIH to keep it simple.  

Just yanking your chain 1447, no disrespect meant.  Hope you can get your problems solved, those can be very frustrating.

Check the drives where they intersect the wings.or turn the alarm off and plant

Make sure the drives are perfectly aligned

Problem solved.  When rub tires installed, 18 tooth sprocket for wings drove a  20 tooth.  20/20 found the problem, I had to disassemble drives.  Word of caution, JD 7000 planter sprockets won't work on 40 chain, must be 2040 chain.  Who uses that with high population.  $80 gone, no return, less 20%.
