SW Minnesota | I have read thru quite a few past posts on here about the walker bearings on JD 9xxx series combines, and the pros and cons of aluminum vs. wood bearings. All of the discussion on this subject is centered around 9000 or 9000 TEN Series machines. I didn't find any of this discussion on a 50 or 60 Series machine. I have a 9560 walker machine, which would be the last series of Deere combines available as a walker machine. It has aluminum walker bearings in it. This machine has a bit over 1400 separator hours on it now and I'm wondering if I should be replacing walker bearings, and if so, which ones to use, aluminum or wood?
