The interim Tier IV tractors have not been any trouble in my experience. We have 5 8235R's ranging from 1000-4000 hours and have had very minimal trouble with any of the emission equipment. The oldest, a 2011 model, couldn't manually clean the exhaust filter once this harvest and had to go to the shop, spent about half a day there. They have been very reliable and enjoyable to operate.
