CNH engines are excellent but they must surely consume far more Adblue than most rivals? This must be better than having to sit idle while others manually regenerate their DPF every so often.Tier 4b with Hi-eSCR , no dpf and no egrNew Holland Launches Tier 4B Compliant T7 Tractors | Tractor News

That's an article from 2015 and at that time i think cnh thought they could meet the requirements for t4b with no dpf or egr. I'm fairly sure that in fact they do have a dpf though (or they may call it a doc) and i think they may have egr.Tier 4b with Hi-eSCR , no dpf and no egrNew Holland Launches Tier 4B Compliant T7 Tractors | Tractor News

I'm not sure they have a DPF even now at Tier 5 level and seem to be using higher level of Selective Catalytic Reduction.
CNH tier 5 tractors need to do it as well.Was caught out with mine the other day,it does a passive burn every 30-40 hours during which you carry on working.You’ve got me curious about this on all tractors with DPF’s. Why would they require a forced regeneration? I’ve run diesel cars and pickups for years and never needed a forced or static regeneration. They just do the regen automatically while working.
Is this a common service issue, to have to stop to do a forced regen? I ask partly because my silage contractor bought a new JD tractor a couple of years ago and I remember it having a forced regen during lunchtime. It was particularly notable because it was stood there, roaring away, not doing any work while creating heat, on my fuel.
CNH engines do have a DPF now since tier 5,but do use less adblu than the previous generation.T6 - STAGE V - ENGINE | New Holland (Apac)

Is yours a T5?
NH have internal egr same as my t3 fergy
That’s very simple and potentially far more reliable than external EGR but is not regulated precisely in real time as computer controlled external EGR is. Not cooled either. I think my 5445 T3 Perkins is a bit heavy on fuel at light loads, possibly as a result of its internal egr emission strategy. Otherwise it is an excellent engine and uses no more fuel at full load as I would expect of a 100hp tractor.
Maxxum 125 so T6 equivalent.
No but it "just works"
Perkins lost a massive slice of its market share with its single fluid EGR strategy, even though their system was relatively simple compared to Deere’s single fluid system which also integrated variable vane turbos and external cooled EGR with its associated piping and valving, sensors and so on. Once the market share was lost, it was lost long term and Perkins are now very rare beasts on new agricultural equipment.
