hey il gleaner they made the pulley change in like 06 or maybe 07 i have been told that you can go back to the old way it with just the single pulley, and yeah i do agree with you on that one that was one of the dumbest moves i have ever saw they want simple then they do something like that its time consuming, otherwise all u had to do was flop the belt to the high side and go now u have to take the pulleys off and rotate them, how did u fix it by the wayIJ riceman we could not get by here with just spreaders gotta have a chopper to chew the stuff up, ilgleaner we set our chopper us as high as we could in beans and thought it helped some we could get 30ft and more dependning on green stems and such, we thought having it set up high helped but for the 40ft not sure if it would that much though, did you like the factory chaff spreadersIJ we had them on our 9690 and now on our 9790 and love em compared to the aftermarket ones. ilgleaner i think the MAV chopper is what you are talking about that spreads the chaff and straw both not seen one work but i would say it would help. ilgleaner we did have problems with little bits of cobs picking wet corn say 28%-around 20% once it got below 20 it got better, yeah we took the reverse bars out of our 9690 ran the last year and thought it helped, we kept them in the 9790 but yeah i still say they are causing the problem with cobs just can't figure out why it don't do it all the time, our dealer said u can relax the concave with the reverse bars i did with the 9690 and never did think it helped any in corn or beans. i do think it grinds up the corn more as well. i'm still thinking of getting rid of our reverse bars out of ours as well. allen marshall, il
