DPF Regeneration driving me crazy...

Air Pollution is a problem -- In population Centers. In Cities.

Yet it doesn’t stay in those population centers. I live on the tail end of the prevailing winds so we get everything which the rest of you send into the air, before it exits to the ocean or goes into Canada.
I’ve seen visibility here drop over the past 40 years, and we’re far from a highly populated region.
I don’t agree with all of the “solutions”, yet I also recognize that we do have pollution problems.

I've lived much of my life around the san francisco bay area. It's a large urban/suburban area with prevailing winds from the west and mountains to the east. The air pollution gets trapped against the mountains and builds up. The visible air quality has improved since the '70s even though the population grew by 40% in that time. That's due to emissions laws for vehicles and stationary sources.

I don't agree with every regulation but they have reduced air pollution.

What emission laws don't you like?

They do make new tractors that don’t do that!

Workmaster 59/60/70 New Holland regeneration isn’t necessary.

Banning wood stoves in new construction. Requiring EPA stoves would be fine. This is a local bay area one, in the populous counties but those have some far flung rural areas with lots of wood. Allowing stoves just in the rural areas would be fine too.

Oxygenates (MTBE or ethanol) in gasoline. They served a purpose back when cars had carburetors or primitive FI but with modern EFI and O2 sensors the EFI just adjusts for it. When you factor in the farming it's actually worse for CO2 than gasoline (though CO2 was not the original target). This one is state and national and given the $$ in ethanol that flows to huge corporations is unlikely to change. In fact they're trying to foist more on us. E15 is out of range for many cars and motorcycles and will damage engines.

In the '90s CARB restricted two stroke off road motorcycles to only half the year (on public lands). I read their docs and they claimed that the average off road motorcycle in the LA basin was ridden 8000 miles a year. Anyone who rides dirt knows that a serious rider will do more like 800 and the average will be more like 80 since most bikes just sit in garages and a lot of people get out only a few times a year. So their claimed savings was bogus. Honda had good clean burning two stroke technology that could have been used.

That's just a start, I could go on at length but I don't want this to become a political thread.

What suggestions would you have that you think might work or be less invasive, with all the things being put out these now....?

Shut your engine off when you aren't using it. Consider fuel economy when buying a vehicle. Instead of buying the cheapest item you can find, pay a bit more for something which (hopefully) will last, even if it means buying used. Donate usable items rather than throwing them out. That's just a few things which I try to do, and aren't necessarily applicable to everybody.

B.S. My Kubota M6060 has done 5 Regens in 75 hours. What a pain in the azz!! I run it at 2200rpm consistently.

This is about what I am seeing, I am trying to to keep it above 2000rpm, but it makes it hard to use in tight spots were a few inches can tear down a fence or two...

I have a 2019 Kubota L6060 with a DPF and was concerned about that system when I bought it, simply because of all the negative information on this forum. My personal experience has been as follows:
1) running the tractor at high rpms does not reduce the time between regens
2) working it under a load, will reduce the regen times and may actually lower the soot levels. I have seen my soot levels drop significantly while using the snowblower while traveling uphill. I suspect that if the tractor is worked hard all the time, it may never regen.
2) when the tractor wants to do a regen, let it and if it calls for more rpms then give it more. Just keep doing whatever you are doing!
3) The only parked regen I have ever done was not actually a "parked regen" because I did not stop the regen, I simply parked the tractor when it started a regen and left it until it was done. Salesman told me that all the problems he ever heard of with regens were caused by the operater not following the proper protocol or stopping regens and not responding properly.
4) I let it idle between operations, just like any tractor.
5) Mine is HST and I run it at around 1500 rpms for most operations (with the auto throttle advance engaged)
5) I have 510 hrs on this tractor and not had any issues with the regen process.

After almost 3 years of use, I have determined the best way to use this tractor is the same way I used my previous tractor and just ignore the Regen process, until I see a flashing light that tells me I need to increase rpm's. I then increase the rpm's until the flashing stops and continue working. I will let the tractor idle when I get out to do something.

For me, this is a non issue.

Before I bought this tractor, I was told the biggest problem with these DPF systems is operator error. Maybe I got lucky the same tractory or other tractor makes / models are prone to issues.

I have the same exact tractor , my model year is 2020. I agree 100 % with this post. Same experiences. Great tractor.

Lot of post's on here about how stupid it is to worry about your tractor going into regen , but it's only stupid if it's not your tractor, I don't own a tractor that needs to regen so I can't say, but I did work out of a 125' hi line bucket truck that was mounted on a Peterbilt semi with a Paquar engine and we had trouble with it every few weeks going into limp mode and having to do forced regen's so it left a bad taste in my mouth with the whole works because in the other 34 years of me doing my job working out of bucket trucks , log skidders, rough terrain cranes etc, all powered with diesel engines we rarely ever had an issue with a diesel engine, they were workhorse's , not setting around in limp mode. Lastly, if man lives in a place to where he can be told that he can't own a wood stove to build a fire in to warm his azz, he needs to get the hell out of there, plenty of places where you can still have a wood stove and build a fire.
