What do you mean by living it's life in auto regen? If it has the latest updates it should be there already. meaning it will automatically start a regen without operator input if it needs a regen provided the engine is warm enough.I spoke to the dealer this morning checking the status of the repair, he said Kubota gave him the ok to replace the dfp and the elbow/exhaust heater prior to the dfp. The cpu listed a fault and premature shutdown during the parked regen d/t a over heat issue... then he said he was install a bra over the front for cold weather applications... go figure.
In addition he states that my cpu is behind on two or three updates that should help as well. All done at least another week to repair.
I also spoke with someone who is very knowledgeable about kubota tractors and their tier 4 emissions. My question, if the dfp is monitored by heat variations within its three zones could the cpu be tricked into thinking all is well and the tractor living itÂ’s life in auto regen? He said yes, but he doesnÂ’t know anyone willing to attempt it.
I think I know someone.
The ecu looks at the differential pressure switch to see if a regen is necessary. It looks at the 3 temperature probes to ensure that the regen is proceeding properly. If the DPF portion was hollow it "likely" wouldn't ever trigger the need for a regen. I can't guarantee that though because there might be other trickery in there to detect the absence of the DPF. It is your tractor, you can experiment with it if you want! LOL I know of one SVL90-2 that has run good for the last 4 years with the DPF hollowed out, and never called for a regen in that time. SVL's use a different system though.. If I were trying it I would leave the DOC portion intact and just remove the DPF.. Theoretically, if you were to run the engine hard enough it would automatically keep the DPF hot enough to burn itself clean and never need a regen so I doubt that there is a timer in there that makes it regen after a specific amount of hours but the Kubota service reps tell me there is. Only trying it would tell you for sure! DPF's are kinda expensive to experiment with though! If it doesn't work you would need to buy a new one.
The "exhaust heater" is called a reformer. It has been changed at least once during the 3350 model run. If, as you say, the ECU firmware in your 3350 is not current, the reformer almost certainly will not be as well. This is likely why Kubota decided to replace it. It is a VERY expensive part.I spoke to the dealer this morning checking the status of the repair, he said Kubota gave him the ok to replace the dfp and the elbow/exhaust heater prior to the dfp.

Agreed.
I'd like to get hold of one too! I can't see why it would be very difficult to eliminate all that crap on these machines.I've looked into this quite a bit, and I'm surprised someone hasn't just eliminated the emissions system completely, it's a mechanical fuel injected engine, there is nothing to stop it from running if done properly.
there are no controls to it that can't be bypassed.
There are plenty of V1505 non emissions engines out there for cheap enough that one could pull the whole engine and emissions system out and replace it with an older version of the same motor, with more HP and no emissions headaches.
This of course is all just speaking off the cuff and I for one would never do such a hideous thing as to make a non performing emissions regulated tractor perform without it's emissions...
Anyone got a B3350 that they wanna dump for cheap because it doesn't run?
Click on the small image and it should pop up full size, or at least it does for me. Anyone else having trouble?
Just call it a B2650.5I've looked into this quite a bit, and I'm surprised someone hasn't just eliminated the emissions system completely, it's a mechanical fuel injected engine, there is nothing to stop it from running if done properly.
