The first 22 years of my engineering career involved combines where we left our exhaust behind us, well behind us. With Cat I was where to send the exhaust so you don't kill the crew, a requirement from our customers.
Hey that's me! For what its worth, there is a HUGE amount of marginally correct or flat out wrong information in this thread. I don't have the hours it would take to correct it all, but for what its worth... information gleaned from internet forums should not be considered gospel.

Excellent video, cleared up a ton of questions for me.Hey that's me!

Let me ADD that Cummins also has an emissions division. So, even though it is not there engine it maybe there controls.Going to go out on a limb again. I think you are going to see gas engines offered in your light/utility tractors. The hobby farm/residential owners are going to have a hard time justifying the increase in purchase and maintenance costs for diesel. Cummins did not jump into bed with westport for grins. Cummins Westport - About Us Yes, Cummins has gas engines in there product line. A Cummins Gasoline Engine? - Diesel Progress - July 2014 So, Cummins has had a good relationship with New Holland. My prediction is you will see gas fired engines in New Holland tractors sooner than latter. Maybe some other tractor manufacturer first, but it just makes sense.

Can I ask you a couple questions?
On the older model tractor where the must depress button to engage auto regen, what happens when they do not?
lights will flash on the dash once the DPF restricts telling them to do it, if they ignore that and keep running eventually they will end up in "limp" mode, if they still keep running it shuts down and you need a laptop to recover the machine.
we probably see as many problems with these systems from simple operator ignorance than we do from actual mechanical issues.
Once it goes into limp mode can the operator still do a regen? Do you know an amount of time they can ignore it?lights will flash on the dash once the DPF restricts telling them to do it, if they ignore that and keep running eventually they will end up in "limp" mode, if they still keep running it shuts down and you need a laptop to recover the machine.

By the time they got to the tractors they had most of the bugs worked out, so I agree with him.Spoken like a true retailer.....![]()

Once you have to do a service regen, can the customer have the DPF cleaned? then install and not need service call to reset ecm?
Thanks again.

Yea, the operator can do a parked regen in limp mode. The amount of time you can get buy will all depend on the exhaust stream. You can't really put times to anything with a DPF as its all determined by the operating conditions.
I'll screw up some detail of this, but there are 5 stages to the cleaning requirement. Running regen indicator - parked regen indicator - derate - laptop regren required - dead. When you get to the bottom stages the only recovery option is plugging in the laptop, cleaning it won't do it. some of these things run on timers.. its not all sensors. Really buy the point that's required, the operator has ignored notifications for hours and on most machines where auto-regen is the default they would have had to bypass the regen several times.
Maybe I'll do another video on this sometime that goes over some of this detail, and shows the regen process running with a laptop hooked up. Thats when these things clicked for me.
I'm wondering if there's a way to know when the process has gone passed the point of no return.
As to the Shibauru - See my earlier posts on Mahindra's similar non DPF Tier 4 technology. (Links to a data sheet and also a video are included). I was sold on it with my recent purchase.
