Kubota Regeneration

[RickB]

If the tractor is not calling for a regen you don't need expensive wiring harnesses and ECU's. The tractor will just keep running like there is no problem. I was told that all I needed to do was remove the differential sensor and keep running my machine because it tricks the ECU into thinking that there is no problem. Unfortunately my CEL had already been triggered and the tractor put into limp mode. So I had to bring it back to the dealer for the 3rd time in 8 weeks for the same problem.

The first three sentences of your post are contradictory.
A common rail engine will not run without a functional ECU and other connected components.

True. You missed this part at the bottom. I did mis-read your above post. I agree that the expensive harnesses and all the electronics is a PITA. Eventually it will come back
to bite us in the butt, not the manufacturers.

Not sure if there are differential pressure sensors in the DPFs used on common rail injected Kubota tractors.

There definitely are none on the mechanically injected B3350, which operates open loop.

Yes, the entire nonsense will eventually bite the owners in the but as the machinery ages.

The good news: Emissions issues with off road engines is a minor problem compared to the troubles such nonsense is causing to the heavy truck industry. Nonsense is unsustainable in the long term, and the trucking industry has a well-established lobby. This nonsense will eventually be rolled back but how long this takes will depend upon the next election.

No it's the little V6 eco-diesel 3.0 liter.

I've read that they are troublesome engines. Kind of surprised it's not a removable inner element. Must be a FCA thing.

I'll keep running my Pre tier 4 engines. I like to see the smoke anyway. I know it's making power...

I think (personal opinion and observation) that the root of the issue is lowest bidder components in the emissions systems.

Guess the 64 dollar question is, who foots the repair bill when the engines are no longer under warranty? Stuff is new enough now that dealers and parent companies eat the repair costs but down the road, I wonder how it will play. Not having any, I don't know what the warranty period on emissions related components are but it has to be a finite duration.

I know I'd never buy a used tractor that had emissions hardware, one never knows if it's good, bad or just plain ugly.

Sounds to me like resale on them will be in the tank.

You really need to ask?

My L3301 did its first regen at 43 hrs last weekend. I was using the rotary cutter at the time and worked right through it without any issue.

On commercial fleet's and on the road non agriculture trucks you have no choice. Fines are a consideration and being able to pass yrly insp is the biggest issue. But the idea that I can be in my tractor 2am in the morning keeping my road clear in a blizzard and having my machine forcing me to stop for a Regen is mind numbing. I don't know much about the systems used in tractors buy have seen the horror shows that low rpm stop and go fleet's go thru. Garbage companies, school bus and city transportation are going thru **** with these DPF systems. Alot of school bus companies are actually switching back to gas engines and propane power now. The idea that an individual who takes care of a small farm or personal property with a tractor having to burdened with a system that's bound to fail and cost a fortune is insane. My advice is do the research and rip the thing out as soon as the warranty period is up or buy a pre DPF machine.

Kioti has a 5 year warranty on emissions. Time will tell on how long these last. The cost to repair these systems in not going to be cheap. It is nice not to have to smell diesel fumes when working with a tractor all day. I don't miss the stink from my last tractor. I do miss not having my tractor when it is not running right.

My thoughts too. No need to ask for that answer!

My tractors don't 'stink' at all. Combusted diesel has little smell compared to say an DEF overdosing diesel engine that will make your eyes water.

You buy the emissions compliant diesel engines, and at some point way down the road, you get to pay for the components, when they fail...

I will say (from experience with Class 8 compliant engines that cleaning a DPF cartridge will cost between 300 and 500 bucks and often times replacement is necessary and that can be upwards of $1000 bucks. I saw that play out many times with big trucks and the emission control warranty don't cover that, you cover that out of your pocket because the cartridge is considered a consumable item. It consumes your money.....:laughing:

I know my dealer personally as well as his head mechanic or should I say 'technician' and I asked him candidly one time a while ago about the emissions junk and his reply was.... I just sell and service them but my personal engines are all pre Tier 4.

Guess that covers that.

As far as I know none of the tractors force you to stop to do a regen. Now, who knows how they will be once they are 10 years old, problems may develop or not. I do believe there is a lot of misunderstanding of how they work. Would be nice to not have the DPF but it is a fact that new tractors have them. Hopefully they keep working and do not cause major issues down the road. I don't expect major problems with mine with the hours I will use it, just have to wait and see. In the mean time I will enjoy using it and not spend any time worrying about something that has not happened yet.

The EPA has mandated the 5 year emissions system warranty. It is identical across all manufacturers.

Kioti's regen cycle starts out with a solid light and the RPM's go down to 2100. If the system works fine you are all set. If that regen light starts blinking you need to stop what your doing, put it in neutral, lock the brake and pull the throttle back to an idle, then hit the manual regen button and wait until it is finished. You can sit there waiting for 30 - 40 minutes. Mine will run for 10 minutes and go straight to the CEL light. Then you have no choice but to trailer it up and bring it back to the dealer again and again for the same problem until somebody figures out what is wrong with it. Mine only does this when I am mowing at 2500 rpm's and there is very little load on the tractor from mowing because I run it slow knowing that it is going to screw up again.

Maybe the email I sent to the EPA today about my tractor will get something done to have mine repaired properly since it is still under warranty.

I’m sure they will get right on it.

Good grief. If I was farming with one and it did that...well, I'd be pizzed big time.

That is why I have had enough of it. Time and time again.
