DPF

And it’s subsidized.

Of course with our money. Did any of you vote for ethanol?

The farmers that voted for ethanol probably think a JOHN DEERE 9R 440 is a small tractor.

The wife and I went to a town nearby for a Dr appmt and there is a pretty big Kubota dealer there. I said to her that one of these days I'm gonna stop in there instead of talk about it. But one question I have to ask of them might be better here: "When does DPF come into the scene when buying a new tractor?" It seems I've heard that it is a function of HP? Is this true of all manufacturers?

I have to say outright I would NOT buy a new tractor that required DPF. And I sure the heck would spend mega bucks and void the warranty with a defeat mod. So, folks, what's the skinny on new tractors and DPF?

Soon all that crap will disappear. Changes at the EPA. That is what you should be talking about. Wait a little longer till the dust settles.

Something to think about (which I haven't seen mentioned), is that some manufacturers have figured out how to avoid DPF in 25-75 HP machines. Mahindra and Massey Ferguson come to mind. My son-in-law's new John Deere 5075E has no DPF. For me, DPF has only caused one issue with my Kioti. That was operator error (my brother-in-law). Otherwise, it occurs automatically; or can be done manually. It's no big deal - except when it's happening automatically and I'm finished working! In which case, I just find something else to work the tractor a little longer.

I’m really surprised I haven’t seen anyone talk about Mahindra Tractors on this thread, only 1 other.
I’ve owned three Mahindra Tractors and never had to worry about DEF. From my understanding, Mahindra has been able to recycle the exhaust and avoid, legally, the need for DEF up to 100 HP. I’m sure other manufacturers will catch up to the Mahindras one day but for now. The burned diesel smells a little different from the old days but not near as bad as after you run DEF. I have borrowed a friends Kubota and swore I’d never buy another tractor that had to regin!

The New Holland and Case utility tractors up to 75 hp such as my Workmaster 75, not made by LS, uses DOC/EGR instead of a DPF. The smaller CUTs made by LS use DPF.

Up to 25HP, the emissions requirements can be met without DPF, DEF, EGR, etc.

25hp up to 75HP, that's were the DPF appears. On most engines, EGR and EGR coolers also come into play.

From 75HP and up, it's all the above, plus DEF.

Somehow Mahindra beat this on their mid-sized tractors when I bought my Kioti back in 2016. I looked at a 55hp Mahindra that didn’t have a DPF system on it like my 45hp Kioti did.

I have a BadBoy (Kukeje) 4025 and it is the same motor as the 4035 that has def. You can put a tune on the 25 to take it to 35. Same motor.

Neither have DEF. Only DPF for the Kioti and DOC for the Mahindra.

What Mahindra does is using a DOC. A DOC is more or less a DPF without a way to force a Regen. It relies solely on good engine loads to keep the exhaust temps high enough that it continuously burns the particles inside the DOC.

The issue with this system is that it can get clogged, really clogged if the engine is not ran hard enough. A good drive on the road in the highest gear every once in a while takes care of it though.

This was also how Branson did initially, when emissions came into play.

I understand a lot of this stuff is going away. The OBBB and the changes going on at EPA should end a lot of this stuff.

I just spent $5,000 on Emissions Equipment for my Ram Cummins Diesel. It breaks. Bigly. And when it does, it's expensive. Bigly.

For those of you that haven't experieced it, good. I hope you never do. But if you do -- Good luck.

My neighbor spent $6500 on his Ford F250 diesel emissions. He then traded the truck in on a gas job because the dealer said that this issue was going to happen again with it.
