Combines Check your spindle bushings

I was made aware of this a few years back when I purchased my machine but haven't given it much thought since. What year is your machine and how many hours do you have on itIJ I'm looking for comparison when I do mine. TIA Deerebines

Soory it has taken me so long to reply. The 9600 is a '95 model w_ about 3000 engine hours. The 8820 is a '82 model w_ about 3000 hours also. How's the weather and crops where you are atIJ I'm located in central ND. We are getting pretty dry here. If we don't get any rain in the next week things are going to go downhill pretty fast.
