I have run axial flows for about 18 years, I need to buy a newer combine and have been noticing New Holland TR machines seem to be cheap compared to their red and green counterparts. Is there a reason for this? I am going to look at a couple of TR 98s, what are the weak points to look for on a 98 or any other twin rotor? I am sure I could do with a TR 88 but they don't seem to be as plentiful. Any ideas how many hours you can put on a TR 98 before they become more trouble than they are worth? Thanks for the help.
