If I was in the market for a new CUT of more than 27 hp, I would look for and consider paying more for a late model , pre Tier 4, if one could be found with low hours and in good condition. Tier 4 compliant CUT's use more fuel to produce less power.
If enough efficiency improvement could be found to make up for the "clean exhaust" losses, then I would lean more towards a Tier 4 compliant model.
The problem is, most of the engineering development is now focusing on electric and hydrogen power. That makes it unlikely that enough added efficiency will ever be found to make a Tier 4 compliant diesel CUT cost effective.
