I have a 2019 Kubota L6060 with a DPF and was concerned about that system when I bought it, simply because of all the negative information on this forum. My personal experience has been as follows:
1) running the tractor at high rpms does not reduce the time between regens
2) working it under a load, will reduce the regen times and may actually lower the soot levels. I have seen my soot levels drop significantly while using the snowblower while traveling uphill. I suspect that if the tractor is worked hard all the time, it may never regen.
2) when the tractor wants to do a regen, let it and if it calls for more rpms then give it more. Just keep doing whatever you are doing!
3) The only parked regen I have ever done was not actually a "parked regen" because I did not stop the regen, I simply parked the tractor when it started a regen and left it until it was done. Salesman told me that all the problems he ever heard of with regens were caused by the operater not following the proper protocol or stopping regens and not responding properly.
4) I let it idle between operations, just like any tractor.
5) Mine is HST and I run it at around 1500 rpms for most operations (with the auto throttle advance engaged)
5) I have 510 hrs on this tractor and not had any issues with the regen process.
After almost 3 years of use, I have determined the best way to use this tractor is the same way I used my previous tractor and just ignore the Regen process, until I see a flashing light that tells me I need to increase rpm's. I then increase the rpm's until the flashing stops and continue working. I will let the tractor idle when I get out to do something.
For me, this is a non issue.
Before I bought this tractor, I was told the biggest problem with these DPF systems is operator error. Maybe I got lucky or other tractor makes / models are prone to issues.
