Promising news on emissions requirements?!?

The recent EPA announcement has me thinking that there could be some good news in the compact tractor market before long.

TYM would be in a good position to make some easy changes (swap DPF with muffler and remove small amount of extra sensors, etc), and I bet that they would do so if allowed because it would save them some $$$ and remove a potential problem for their customers.

Ah, to dream.

Funny enough TYM's Kukje/Cummins/Onan design engines seem to have some of the least emission problems overall! I still haven't had a regen in 613hours on mine in over 5 years. It is as reliable as a old Toyota.

Kukje runs the DOC hot enough so the DPF doesn't need to do regens under typical use. On my Branson there's no way to do a regen. Some people had trouble with that. Mostly people in places that get cold who were using the tractor for short periods. Like if you only use it to feed a round bale every few days during the winter. Some folks here had theirs clog up.

Branson added a way to force a regen, along with the exhaust valve to keep heat in the DPF, at the same time they went from a three speed to a four speed range transmission. Doing a regen would handle the relatively few people who had clogging problems.

I'm reading today the particulate regulations will remain. It's the "greenhouse gas" regulations that are being rolled back. So I guess our DPFs are here to stay.

That sounds like something's wrong with your tractor. Better take it in and have it fixed.

What I'm hearing is that even if the regulations are dropped the manufacturers won't change anything. The cost to do so is preventative. Especially if you add the fact that a new administration can change the regs back to what they were.

To be fair, TYMs would be the least affected... Since they #1 almost never regen. None of this 30-50 our noise. #2 a TYM can be deleted without the tractor going into limp mode, unlike any other brand on the market as far as I know. The tractor doesn't care if the can is on, or off, it will run.

Maybe

Maybe the aftermarket will be unleashed if penalties no longer apply?

Am I the only person on earth that actually likes my DPF? I guess implementations may vary, but on my 3033r, it has been totally trouble-free. Every time I have to run an old 855 or 950, I remember how bad it was, being choked out of the shed while hooking up implements or even warming up a little on a cold morning. My God, those things stank. The 3033r exhaust smells like unicorn farts, by comparison.

I only have two very minor gripes with my DPF'd tractor, which I'll gladly accept:

1. It does run a heck of a lot hotter, to where some summer chores can feel like you're standing in front of a barbeque grill. Thankfully, 90% of my tractor usage is in cooler weather, so that doesn't really matter to me. Heck, it's a bonus in winter.

2. Deere's user interface and indicators telling you what the regen status is could not have been more confusing, if they tried, and it seems my particular model or year doesn't match ANY of the others I find posted online or YouTube. I literally have to pull out the manual and try to decode what the various cryptic blinking symbols mean, half the time. Whoever designed that display system should be hung by their toenails, but that gripe is all about Deere display quirks, not DPF technology.
