Our 485QT has one bogey wheel that is running about 5-8 degrees warmer than the rest in the field and after bringing the tractor home from 15 miles away, it ran about 20 degrees warmer. We have been checking them with a laser thermometer all spring and it is not leaking oil and it is full. Should I take it apart or change the oil or just watch it some more? The tractor has about 1300 hrs.
