Final Tier IV seems to have fewer problems than interim Tier IV. Having DEF seems to be a better situation than a tractor with Diesel Particulate Filter - DPF and EGR - exhaust gas recirculation... (Don't you just love all those acronyms!). Biggest concerns seems to be - what happens when the tractor has 4000+ hours and you have to replace the SOC and the DOC - selective oxidizing catalyst and diesel oxidizing catalyst.
Today's cost is somewhere in the neighborhood of $7,000-8,000!
As ovrszd stated, the new tractors, trucks, all have it! If you're looking at a new machine - you will have a DEF tank!
Friend of mine owns 8 over the road semis. 3 are final Tier IV. They are the least problem.
The road grader I run is Interim Tier IV with a DPF. It's estimated cost is $4000 to be replaced at 4000 hours.
