1990CCS with Greenstar2 counts low for population
Picked up a 40’ 1990CCS air drill last year, came with the Greenstar 1800 monitor. Last year it counted low on population, had to run as much as 20,000 or more less than our desired population to get a pro box of seed to go as far as it should.
I’ve removed all the seed sensors and cleaned them which made no difference.
The low seed warning sensors also don’t work nor does the population adjust. I pulled the small gearmotor off the transmission and checked it, it works in both directions with an external power supply.
I’m wondering if I could have a bad module on the drill even though the swath control works.
