My kubota 2015 l3901 just passed 400h. It goes into regen every 18-20 h. It drive me nut. I like this tractor a lot but hate the regen stuff.
Is 20 regen normal?

18~20 hours? No regen here so no clue, but it doesn’t sound too excessive.My kubota 2015 l3901 just passed 400h. It goes into regen every 18-20 h. It drive me nut. I like this tractor a lot but hate the regen stuff.

For the next 20 hours - or hopefully it will be more, run it at 2400 all the way around.Every 20 hours.
I do run the tractor at 1800 rpm most of the time. When i am on the backhoe: rpm at 2200
Its about normal given your decision to only run at 1800 rpm per statement below. Why do you want to operate rpm's below designed operating range?My kubota 2015 l3901 just passed 400h. It goes into regen every 18-20 h. It drive me nut. I like this tractor a lot but hate the regen stuff.

My experience is close to 40 hours between regens if you keep engine RPM in the 2200+ range and avoid short run times.That allows the DPF to clean itself without help from the ECU.Every 20 hours.

I use the MX all winter long to push and blow snow and rarely does the tractor do a regen. I start out blowing downhill at 2,200 rpm for about 200 yards, then push snow on the lower driveway at 2,000 rpm for another 200 yards. I turn around at the bottom and then come back up the lower driveway at 2,400 rpm (it's fairly steep), then rinse & repeat. Coming back up the driveway puts the tractor under a good load and the DPF is hottest in those moments. When I'm clearing the parking areas in front of the house and garage I'm running at 2,200 rpm.Thx you all for your advise.
I didn't realize it was better to run it at 2200-2400 all the time. Will do. It all make sense now.
So... help me understand this....For the next 20 hours - or hopefully it will be more, run it at 2400 all the way around.
That 2400 is not even max RPM according to the data.
The problem with Tier IV is that you have to get the screen at the exhaust really hot to burn those particulates off. You will not hurt the engine running it in that range.
Hard to measure that in isolation. The facts on the ground are it ts a common rail diesel with DPF, governed max engine speed of 2700 RPM, and designed to run all day at 540 PTO speed (2400 engine RPM).So... help me understand this....
Pistons/rods/crank, etc., running at 1800 RPM (or less) wear ("not hurt") at exactly the same rate as those running at 2400 RPM?
I think you missed my point!Hard to measure that in isolation. The facts on the ground are it ts a common rail diesel with DPF, governed max engine speed of 2700 RPM, and designed to run all day at 540 PTO speed (2400 engine RPM).
So do you think running at 1800 RPM with active regens every 20 hours results in more or less engine wear than running at 2400 PTO speed and halving the number of active regens?
It would be an interesting engine stand test. I would be inclined to bet on fewer regens reducing engine deposits and wear = longer engine life.

Ok - you have never worked commerical construction that I know of - you have never operated a half mil dollar machine - you believe all you want. Easter bunny, santa claus - unicorns, I care not. I just know that limping a diesel around does IT NO good!I DO NOT believe that!
You are correct,.....sort of...Ok - you have never worked commerical construction that I know of - you have never operated a half mil dollar machine - you believe all you want. Easter bunny, santa claus - unicorns, I care not. I just know that limping a diesel around does IT NO good!
KUBOTA designed it to run - NO WHERE IN THE manual does it say dperate at high idle - other than to warm the machine up!!!
Remember something - you do you, and the rest of us will do ............... US!

Depending ON the Tier of the engine!!!!!! AND the size and the DESIGN!You are correct,.....sort of...
It is a known fact that diesels in general, operate most efficiently at, or below, 1800 RPM.
I think you are the one missing the point.I think you missed my point!
I don't care one iota about "regens", I will never have one.
Your comment seems to indicate that you believe that any engine run at 2400 RPM will last just as long as the same one run at 1800 RPM.
I DO NOT believe that!
