DPF Regeneration driving me crazy...

[slider909]

Are we talking gas or diesel engines? Tacoma, I presume gas. Even gas engines do not reach expected performance at idle and probably become prone to fouled plugs if idled for extended periods regularly.

Foul a plug? Can't happen with any ECU engine. Outside of it being a beater that is.

I knew the regeneration cycle would be happening as I kept away from the larger diesels as my buddy burnt two engines up on his trucks. But the regeneration lights come on, right as I am in the middle of something, or it starts beeping and I have to stop immediately out in the field and find a empty spot to regenerate so I dont set the whole forest on fire. This is nuts...

You are making it too hard. Just run your machine at a higher rpm and the regens will come at much longer intervals. Also, just work through a regen--no need to stop working. When a regen is called for, just increase the rpm sufficient to run the regen and keep working.

Wait till they start changing over to battery powered tractors.

Once every 60+ hours for 10-15 minutes. Don’t be so dramatic.

No, it's asinine. Had a stone delivery a few months back. Mushy ground. The driver got thru, dumped his stone and went to make a run thru the wet clay incline hill on my property. Got right into the mush when his truck went into this mode, engine drops in power. Tires spun, it was over. Two outs getting him out just because of this nonsense. Running a diesel used to be cheap
The fuel was very cheap as its a by product of gas. Of course now it is pricier then premium gas. Then you add the expense of DPF fluid. Then the DEF. All this expense gets passed down to the poor consumer

Have a JD 3046R with 500 hours. Probably has regened 4 times when under no load splitting wood. I just keep working as JD says. If you are getting a PARK Regen warning you have anissue somewhere

I have to chuckle, because I've just been researching whether there's inexpensive way to retrofit a DPF on my older New Holland. Yes, it will be inconvenient once in a while... but I'm the guy breathing the soot, and I'm so far behind in all of my projects that I can't afford to die any earlier than I have to.

Seriously though, the thoughtful comments about what systems are working (or not) is all helpful.

I love your connection to life’s needs over the grim reapers needs!
I’m in about the same position… I can’t die until I clean up my balance sheet (and I’m not talking about money !! )

Same here… I have only had 2 situations in 2 years where I had to let the system regen by putting it in spec rpm and letting it go. Both of those times were because I canceled the regen while doing some off and on work where I needed to consistently change activities with the implements or equip. I was using. Other than that it regens when it wants. It’s a symbiotic relationship of sorts.
I have never been “surprised” by a regen. The display keeps it in my face. So I can work around it’s needs.

I can wait . . .

Others correct me if I'm wrong...but when I was doing my research, shopping for a new tractor, I learned that tractors using the DOC versus the DPF still need to be run hot and hard. That "C" in DOC stands for catalyst - and that catalyst won't burn off soot if it is not hot. Owner's manuals still had warnings to not idle the tractor too much - just as the owner's manual in my Kubota (DPF) does.

The DOC system means that regeneration is going on continuously, versus every so many hours as happens with a DPF system.

Yes that is correct. Also most if not all "DPF" systems actually have both a DOC and a DPF. Look at for example the parts list for a Kubota L4060. My Branson also has both.

Both DOC and DOC+DPF systems do "pasive regeneration" when the engine get it hot enough because it's working hard. The more you do that the fewer discrete regens will be needed. My Branson only does passive regens which has been a problem for a few folks in cold area; newer Bransons have the ability to command a discrete regen to handle that.


Here's an article that explains the DOC+DPF system: https://www.dpfpartsdirect.com/blogs/news/dpf-doc
It's for on the road trucks, newer models of which also use DEF unlike our < 75hp CUTS but other than that it's the same.

There are companies like this one: DPF DOC througout the country that will clean the DPF (and DOC) for you. The OP may need that in addition to letting his tractor regen when it needs it, and running it at appropriate rpm.

Has anyone ever tried those additives that supposedly help with the DPF regenerations? If yes, did it make any difference?

Like this Motul DPF Clean? MOTUL DPF CLEAN - Motul

Had to replace the injectors on my 2014 MF 1739 @150 hrs because it was stuck in regen mode...very disappointed in this tractor..its a piece of crap in my opinion now...but not like I'm gonna get rid of it ..just stuck with it..

there you go, Mikester

excellent point(s) and one that many younger generation people are fine with because they accept having their livelihoods controlled by government bureaucrats and global elites. I guess owning something outright (bought and paid for) means you only own it by permission (subscription) and if you don't comply we will shut you down.
I have a 2012 Kioti Dk 40 clutch.......I bought in 2013 but was able to get the 2012 model (no hydros left but i wanted a manual trans anyway) The point being that in 2013 the new models were required by government to phase in the regens and other emission electronics. The regens to be the final solution? yes, nothing is final with the bureaucrats in charge. (the main course here comes with a full serving of fossil fuel elimination) or at least make it so expensive you can't afford having anything that might give you some independent control of your life.

anyway your point about repair is also well taken, as many of us are not "suburban" owners. I live 30 miles from parts and repair so it is in my best interest to be able to diagnose and fix most repair issues at the time (or before) they occur....If you just have the basics then it's much easier and more efficient to get up and running ASAP.....My rig has some electronics but pretty basic and learnable....So far I have been able to fix and diagnose issues , but I also do routine maintenance and have a pretty good sense for something that doesn't sound or feel right. Most of my issues have not been the fault of the tractor, rather me doing dumb things.So I guess Kioti has gotten most things right.
One other note my tractor does put out emissions but it is not black soot......grey-white and not much..... RPM's go up emissions almost disappear. I, like most conscious machine owners, appreciate clean air but we must also understand that there is a proportional component to how much a small land owner contributes and at what cost. Also if you are losing efficiency and therefore burning more fuel where does that cost trade off factor in? When you can no longer afford the product that you need to survive?
....... Remember the subscription scene as stated by mikester. It is very real and I have several examples. Once the elitists get control they will not compromise, they will never stop until they own you entirely.....there's a 2022 reality check out there. Take a good hard look.

I have about 65 hours on my 47 HP kioti Not one regen cycle. But then I don't run it slow an awful lot. I've been asking an awful lot of the machine so I need the max available horsepower.

You can sell it for more than you might imagine what with the supply chain nightmare

Well, they will force everyone into electric tractors in a bit, so soon it will be a moot point....LOL

 

[tractortroof]

Great technical info. Thank you!

Since he started having problems at like 100 hours, do ya think the prediction of 20k hours is possibly a little ambitious?

 

[Johnb0311]

Are you sure? I only have one machine with the new . . . and I run it pretty much at pto rated speed . . . it has regened a few times, it has maybe 200 hrs. on it.

I mis-posted about operating speed. meant to operate at reccomended speeds. Sorry.

 

[litework]

I don’t get too bothered by the regenerations. I’m not going to change the way I operate my tractor to lengthen the span of time between regens. Long periods of time at higher RPMs to lengthen the span of time between regens vs. shorter periods of time at very high RPMs during regen seems like the same thing to me. I’ve operated tractors for some time now and I just do things my way. This is my first machine with a DPF so it’s a new experience. I only have 30 hours on my tractor and two regens – each after 15 hours. I tried to do a parked regeneration the first time and it wasn’t as smooth as the second time. The second time, I was pushing snow around and just turned up the RPMs per the tractor’s “request” and, as others have said, I didn’t even notice it at all. I did have to interrupt the cycle when it first came on because I was inside the garage and wasn’t ready. Still, no big deal at all. I have an HST so the speed control is irrespective of tractor RPMs. Maybe it's easier??

 

[Jstpssng]

One time when it asked to Regen I had put my backhoe on and was getting ready to use it. It dug a whole lot better than the RPMs I normally run it at...

No, it's asinine. Had a stone delivery a few months back. Mushy ground. The driver got thru, dumped his stone and went to make a run thru the wet clay incline hill on my property. Got right into the mush when his truck went into this mode, engine drops in power. Tires spun, it was over. Two outs getting him out just because of this nonsense. Running a diesel used to be cheap
The fuel was very cheap as its a by product of gas. Of course now it is pricier then premium gas. Then you add the expense of DPF fluid. Then the DEF. All this expense gets passed down to the poor consumer

Diesel is not a byproduct of gasoline.

Diesel is a crude oil product that does not take as much energy to produce as gasoline.
