Hi

I am n harvesting contractor from South Africa .We bout a new 9570 sts last year just before the corn season. The problem that we have is that it spills corn over the rotor on to the ground at the back of the harvester.We adjusted and played with the moving speed it just stade the same.This is a real problem for us as we are getting complaints from our customers.Do you guys have the same problem it so what did you do to correct it.

Thanks

The tip that we got from JD south afrika was that we fit the rice concaves and remove every second wire from it. But we havent test it jet as we will only start haversting in june.yes it is defnetly rotor loss we did a power shat down to see.
