DPF Regeneration driving me crazy...

[CloverKnollFarms]

2300 regens would take most CUT owners a couple of decades.

That will out live the tractor, by far

The system might handle it but the sensors etc wont.

Speculation. People have been hand wringing about electronics on vehicles for 40 years now, yet new vehicles are far more dependable than the 1970s era vehicles.

If you are running a constant 2200 RPM's you should not be having an excessive number of regens. High numbers of regens are usually a symptom of idling a lot. I'd keep a log and if they are occurring every few hours I'd call the dealer about it.

I actually prefer for the regen to occur when I'm working the tractor hard. You can just keep working as opposed to having to let it sit at high(er) RPM's to complete the regen when the regen light comes on while you are idling the tractor.

The problem is not all tractor work requires high RPMs. Heck I use the BH at ~1700 RPM half the time. On the M4 when I'm in H6 it is governed at 24 MPM and 2050 RPM which is below the regen threshold, go figure. Just "keep it at high RPMs" briefs well but doesn't necessary work in the real world.

Yup....the new stuff is just ugly and no personalities.

Cool story bro, I've replaced four of six in my F250 at less than 95K miles.

F250 power stroke. Just saying. Not an issue with Cummins

You purchase a new post 4 tractor you get all the emissions stuff at no additional charge... Just think, after 2300 regens (about), you get to replace the cannister too. (Kubota estimates 2300 regens before replacement / cleaning). Don't worry, it won't be under warranty at 2300 cycles. Federal emissions warranty is 5 years. Once past that, it's your dime.

Are you actually fear mongering about possibly replacing a DPF can on a tractor after 20,000+ hours of use? So basically, no one will have to do this? Sounds pretty acceptable to me.

I think some of you need bigger things to worry about. The sky is falling.....well not yet, but someday it probably will. Must be stressful worrying about stupid **** all of the time.

Ohh yeah, you're fine then.

DPF and regen issues are not confined to poor design or electrical problems (sensors or computer) as seems to be the popular goto for service departments.

The attached presentation indicates many other mechanical issues that can lead to constant problems.

It seems most tractor dealer service departments (and manufactures) are oblivious to these causes and just throw parts at it.

 

[JCoastie]

I'm at 16 regens in 250 hours, most in the last 100 hours. Probably more before I realized there was a problem and started documenting them. Dealer is trying to figure out the cause, so far unsuccessfully.
It's currently at the dealership getting a new ECM. Sensor was previously replaced and the DPF cleaned.

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

Well, mine is coming on after 5-6 hours, basically every other day when going hard, so its a bit much. Doesnt seem normal to me, but manual doesnt say anything on how to reduce it...

 

[Reddogs]

It’s not necessary with a Kubota either

I would not be so quick on that. It started to beep yesterday, and manual says to stop everything you are doing and do regen. So why would they say that, if you dont need to do it?

Really? Are you sure you're not reading the section for a parked regen? I've got two Kubota's with regen and neither require you to stop all work other than for parked regen.

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...

This was your Kubota, right?
Deere regen can be cancelled and initiated when convenient...also, the hot exhaust is vented upwards
My 4052 hasn't had to regen yet

That was my first though, that I was idling too much, so have been kicking the revs up, but started beeping yesterday right in the middle of some heavy clearing, and had to find a place to let it regen out in the open.

Kubota L3301 issues

I just acquired a Kubota L3301 Gear Drive Transmission., 3rd Function valve with grapple, with R1 tires. I want to know what issues I should look out for, and what implements I should add and costs, as I would like to farm and use for land clearing.

Was is private sale or from a dealer? Maybe you acquired someone else's problem?

I usually push the button and keep running, but this time it started to beep and would not stop till I regened..

I know at least Kubota recommends delaying regens when in a potentially combustible environment like dry fields etc, but unless the tractor is caked in vegetation I just don't see it as an issue. That said, I would imagine it's safer to avoid it.
My L4060 allows me to inhibit (delay) Regen, but I haven't found the need in my use to utilize that feature. I just work through the regens, which in my case is once every 50 hours. I'm coming up on Regen #17 in 6 years, so I will be long dead before the tractor gets anywhere near 2300.

If I were having regens every 5 hours my opinion would certainly be different.

It was a private sale, but it was immaculate, and all services done.
