We have recently bought our first combine, a 9510. When we got it home we were looking it over and noticed it is equipped with a factory JD dust diverter on the sides of the feederhouse. Upon further inspection, we noticed the bearings were out and the shaft twisted in two, and the impellers were cracked. When we went to the JD store for parts they said they had never laid eyes on a 9510 much less a dust diverter like that. My question is --- are these dust diverters troublesome? Would we be better off not to fix this one and put an aftermarket diverter on? What do ya'll think? Just give me some feedback on these diverters. Thanks in advance.
