Thank you to all for the welcome.
I mow about at least 8 acres with a Kubota F3990. This is the machine that has been causing me headaches with the DPF Regen technology. It has only 324 hrs, new in 2014, and over those years there have had to be four forced regens by the dealer, two this year, an expensive way to address a problem.
I think the dealer suspects this is my fault because the ECM shows that there have been some instances of the engine being stopped during a regen, which is a no no. He says this bumps the regen up to the next level of severity, and in the end the owner has no choice but to ask for the help of the dealer to do the forced regen.
This has happened twice so far this year even though I have become very vigilant to not allow the engine to stop and also to follow all recommended steps for each stage of the regen [engine at low idle, parking brake on, PTO disengaged etc]. Both times this year the on board system went from the lowest stage with only the regen icon lit up, to the highest stage with the engine warning light flashing, in one jump. That is bizarre.
But the first time the dealer came out to do another forced regen in march he said he could find nothing wrong with the technology. Of course, he is able to disable and to subdue embedded bugs in the technology, do his thing, and then all is well, and he feels vindicated. I do not think that Kubota regen technology is exonerated.
I call this temperamental technology because it does not come out and shut me down all the time. There have been enough times when I can remember that I have hopped off the machine to unplug the grass chute and the engine has stopped, and nothing else has happened. Why does it only happen sometimes?? Furthermore, can Kubota not design some technology that is able to recover from the engine being shut off and go back to a restore point and continue to do its regen? That is how my home computer works.
Very long story short......I would like to be rid of this technology and delete it from the ECM module. So far I cannot find someone who can do that even though there are enough people
