Anyone else waiting to see if tractors without the EPA stuff are coming?

I have been hearing of quite a few issues with EPA stuff but so far with close to 500 hours on my LS XR4155 I haven’t experienced any problems

I haven’t had problems either, and if I didn’t have a tier 4 tractor I probably wouldn’t own one anymore. The fumes from my old pre-emissions tractor gave me a severe sinus headache after operating it for 30 minutes. I can operate my tier 4 machine all day without these issues, except when it’s doing a regeneration. But that only happens every 50 hours or so.

Yes, you can turn off DEF/DPF equipment with a laptop. EGR’s require a physical block. IMO, if standards are rolled back, we should be able to shut it off ourselves.

If these are shielded, it should be necessary to remove the aftertreatment carrier from the inside of the exhaust pipe

Post-processing does have an effect
But whether regenerating every 50 hours is a bit too frequent

From another thread; Deutz makes 75HP tractors this way:
"Tier 4 emissions compliant engine with “No Maintenance” emissions system: No SCR, No DPF"
source: 5D Keyline - Deutz-Fahr America
If Deutz can do it, why can't MF, JD, and others?

It does it around 50 hours in the winter and more like 70 hours in the summer.

The EPA is rolling back some emission standards, was just announced. If the official government policy at the time of purchase is "x", then you can't be punished later for adhearing to policy "x".

Get those deletes now boys...

TYMs are easy to delete. Just remove the can.

Maybe the bad rap is from early models or unusual use…

Someone plowing a field might be running hot to delay regen?

Makes you wonder what truck manufacturers, if anything, have to look forward to?
Could be a a real boost to the US manufacturing economy.
I like clean air, but not at the cost of diesel engine reliability. I’m trying to make a living here.
Wonder what todays high efficiency, high PSI injectors with computerized timing would run in terms of exhaust compared to 1990’s engines? Maybe they’d be clean enough to be acceptable?
The after treatment systems have been somewhat perfected. Tim to get rid of the engine issues associated with EGR.

Just about every non compliant big rig is gone plus commercial tractors m, chippers, generators, etc…

California was adamant to see this happened and enforced it various ways including port pickup and deliveries.
