John Deere Keeps Overheating

This tractor is only running an auger and it over heats? Something isn't right. We still do not have our CASE IH Magnum back from our dealership so the JD is all we have (thankful we do). Need to find out what is going on and fix it! With that said we are ready for spring wheat. Repaired the headers, bolted on some new May Wes skid shoes, I think it's go time. Going to be very interesting to see how yields turn out as we hit the fields.
