I posted a couple of days ago about problems I'm having with upper feederhouse sheave bearings and got to wondering if I would be better off changing it to fixed speed drive. I don't use this combine on the corn header anymore, just a flex head in soybeans, so I don't really need the variable speed anyway. I know this was doable on the 50 series because we did it to our 9750 several years ago but I'm not sure if it's available for a 9860. Does anyone know and if so would you have the parts bundle number? Thanks.
