I believe that with the Final Tier 4 engine it will have both def and pm filter, no matter the brand. Case IH went to def in 2012 or 13 and no DPF. JD went with the DPF but no def until 2016. Pretty sure it takes both now to meet Final Tier limits. Here's a link to an old article that explains who did what.
