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!
