I have heard through the grapevine that the deere combines will have a new more aggressive cleaning shoe, the grapevine I talked too has seen the chaffer/seive setupd and said it looks like a pretty good design. He said he hadn't seen the rest of the combine or anything just a few components of it... so I don't expect any radical changes but more capacity in the grain elevators and a better cleaning system.
I also wondered what happened to the original post. I know I didn't delete it. Alex wants to see the pics, so I don't think he would have deleted it either. Oh well. Maybe the original poster had second thoughts.
We have had our combines work alongside Deere pre-production machines and yes they tend to be very protective of their new babies, more so than the prototype and pre-introduction red machines that we have worked with.
Everything seems to be tight where they both mount but are wearing on each. It wore the crank assembly on the top completely off ? I wouldn't think they should even touch each other? Did take belt off to see if the back would turn freely even with the top out but turned very hard by hand . DID...
