I posted a couple questions on another post but didn't get a response. I'll ask again. I am sure the answers are buried in these posts so bear with me if I am being stupid or redundant. We have been using a 9650 sts this fall because our 9500 broke down. Put 40 hrs on it and they are putting the pressure on us to trade up an keep it. It is quite a step up from the 9500 and so much quicker. Needless to say it is really selling itself. I would like to know if our 925 flex head is going to be big enough in beans and wheat. Rotors generally need to be full so I didn't know if I would have to go to a bigger head. We have an eight row corn head so it works. Also is greenstar reliable? Was unable to use it because they didn't send the screen with it. We have found other problems with it that need to be fixed. It is a used combine so there is going to be breaks. It has 1950 sep hrs. Any other things I should know would be a great help. It is our first rotor so many things are new to us. Thanks for your time. Cheers.
