They don’t have a DPF so likely not…..

You hear of the scr canister potentially plugging off. Happens in the truck world but don’t hear much of it in the ag side
No ag FPT engine has a Diesel Particulate Filter to plug.

Do you mean the SCR catalyzer canister? I guess it could theoretically plug up, but that's highly unlikely. There's not much to it except baffles and SCR nozzles. As I said, Case engines don't have any filters because they don't need them. They are already soot free because of the higher exhaust and combustion temperatures they run at (which increases efficiency compared to EGR) and just use SCR to treat the NOx (which is odorless). Other than potentially destroying the DEF injectors, I can't think of any problems in just leaving the canister alone, although the Tier 4F canister is huge on the tractors and would sure look better replaced with a muffler.

Truck engines are a very different story. I don't know of any truck engine that does not do EGR with DPF and SCR today. So if you delete, it is essential to remove the DPF (which is probably integrated with the SCR canister) entirely. One thing you'll notice is a deleted Tier 4 truck engine will smoke you out in the shop because it's quite dirty without the filtering, but a deleted Case engine won't (although the NOx isn't all that good for the lungs either long term).
Have you ever put a case/NH tractor in reverse when it’s not warmed up with a deleted engine? It can fill an enclosed space up in a hurry.

Theoretically the stuff inside the SCR canister can eventually break apart and plug off the canister. That’s why trucks remove both the DPF and scr canister when they do a delete. Trucks put a lot more hours on an engine then a tractor so I don’t know how many hours it would take for that to happen.
