well one day we were up in Regina getting a accelerator belt for our 9650sts, when the man ahead of us had been there for over an hour..... we asked why an hour? he showed us the piece that he was trying to find... it happened to be the drive plate off of the bottom chaffer on his 9650sts, so we looked through his parts book while the parts man at Deere looked through the computer program..... the man let us ahead of hime to get our belt and we left... dad was looking in the parts book that night and found the part.... it was under chaffer in the very front of the book with the feeder house parts numbers.... the John Deere parts man said who ever writes them drinks alot of beer... i couldnt help but laugh
