5030 that would seem to work in theory. But, the ECU would most likely be on a schedule as well. As in my tractor: once it hits the 50hr mark since last regen, exactly 50, it regens. Deleting everything but the SCR can, would likely throw errors and either shut the tractor down or put it in indefinite limp mode.
As to not modifying tractors. I believe that if you are the one making the payments, and you know what you are doing, then go ahead. However, there is a warranty issue with some of us. Say we start tampering with the DPF and void the warranty and then, oh, I dont know, you break an axle. That repair is now not covered. So there is that. And then there is the simple fact that some, just live with it. I was seriously considering changing out the loader control valve on my tractor, screw the warranty. But as time went on, while I researched the manufacture of a better bolt in model, I decided it simply is not worth the cost and effort until something goes wrong with the one that is currently installed.
I dont think people are "afraid" to do things to their tractors that might be out of warranty. I think it is a lack of knowledge or willingness to fix something that might not a real issue. Putting new led lights on a tractor is MUCH different than deleting a major function of the tractor.
Probably has an electronic timer much like printers do today. Printers today have a built in timer that renders the printer inoperable after a pre determined time has elapsed. The call it the cleaning tank full but full or not the printer will default to a non operating status even if you manually change the absorber pads. However, there are workarounds and I bet there is a workaround for the electronic timer in the ECU and I bet the manufacturer knows what it is, but won't tell you. Probably the dealers as well but they aren't telling either. Kind of goes back to the 'Right to Repair' running on this forum presently concerning John Deere.
My good friend down the road has a multi-million dollar commercial seed operation and a fleet of JD's, most are only a year or two old and they are so computerized and have so many sensors on them, you cannot even change the oil and filters and use a generic filter and oil because the filters themselves have sensors in them so you have to use JD filters and JD oils, because the sensors sense the oil flow and restriction and are programmed for JD oils. Some really wild stuff. Talk about emissions compliant, they have huge black metal boxes in the side with the exhaust stack coming out. He told me that black box cost 30 grand to replace.
Amazing what the government has done to the diesel engine in the name of pollution.
I can actually see gas engines making a comeback in tractors, especially the big ones.
One thing to keep in mind when doing any modification to the emissions end and that it, if you do something that cannot be refitted back to original equipment, you are basically stuck with it forever, because it has no trade in or resale value and if you do trade it or sell it knowing that it's non compliant, the next owner can come back on you legally and you have to make them whole.
That could become a sticky situation financially and legally.
Whatever you do, keep the OEM parts and expect to refit it back to OEM configurations if you decide down the road to trade it or sell it.
I tease about having no T4 final tractors but in reality I don't want any. Don't want the hassle or the electronics. Like my friend down the road with the JD's always tells me, just keep what you have and rebuild it if necessary and that is exactly what I do. My newest tractor is a 2004.
I understand your pain and believe me, I'd like to have a new unit or two, just not with the grief associated with them.
