DPF

[Rdrcr]

One thing worth mentioning is that the DPF (Diesel Particulate FILTER), is a serviceable item. Over time the DPF will build up with enough soot that it can no longer be effective and will need to be replaced.

Where does it squirt urine into the exhaust stream? Just before the filter or does it do it like the Cummins diesel (on 3500's) in the engine cylinders? This has shown to add a lot of fuel to the oil in some cases.

Quick Google...
The Selective Catalytic Reduction (SCR) unit is located in the exhaust stream of a diesel vehicle, positioned downstream of the engine and typically after the Diesel Oxidation Catalyst (DOC) and Diesel Particulate Filter (DPF). Diesel Exhaust Fluid (DEF), a urea solution, is injected into the exhaust just before the SCR catalyst, which is a large metallic structure containing the catalyst that converts harmful nitrogen oxides (NOx) into harmless nitrogen and water.

I believe it's like 5000 hrs on many

I believe it's like 5000 hrs on many

Think it will still be available and affordable when the time comes? My 25 year old BX is near 5000 (no EPA stuff) but my LS does have it. Think I will be able to buy that stuff in 25 years? Many tractors are in use for over 30 years in non commercial applications.
Seems like it takes less than 150K miles for many catalytic converters to clog in gas cars, getting ready to cut the one out of my old truck. It is clogged and will not allow more than 30% throttle. No converter in the exhaust she runs like a raped ape, all the lost ponies reappeared.

No emissions testing or requirements in my county, no factory catalytic converters for this 30 year old truck. It's buy from the junk yard, after market or straight pipe.

5000hrs is a lot of hrs. By then or before I think there will be alternatives to replacing it with generic aftermarket units.

Cars don't have the soot like diesels. There are tons of aftermarket CATs you can use that are cheap compared to OEM. Me personally would do the same as you.

My 2004 Dodge Cummins fortunately had no emissions from the factory except egr in the cam profile. I somehow lost that cam.

Now let's address the elephant.

LS used an EGR valve that was failing for some, replacement was not a big deal. The OEM of that valve went out of business and it is no longer available. The replacement requires a new manifold and other parts, then it must have a software change to the ECM to function. This kind of thing will happen over and over to all flavor or tractor. For many of us the tractor should out last us not have to be scrapped for EPA stuff.

I figure my DPF will need replacing at some time, I put about 300-500 hours on the tractor a year. Currently the can is well north of $500 and the dealers want to install it. Dealer is over an hour on way, want a fortune for little labor, lets say a 1000 all in to get it done. I'm miles ahead if I spend 2500 to get the ECM to ignore EGR and DPF, removing all points of expensive failures that do nothing for me.

Pretty sure using a few tires to start a slash burn will emit more pollution than my little tractor will in it's life time. As will all the cars on the road/strip using NOX and CO2 as power adders and venting it directly as needed.

I do not see a strong after market for Tractor emission parts. I expect we will pull together to find solutions to keep them working down the road.

Mine is working fine right now but when it no longer does things will change. Maybe just a few whacks with a long pipe.

Now if you ever see me set a field on fire during a regen (god forbid) it will be bad. I'm surrounded by 3 million acres of government forest that will burn like crazy and is loaded with lots of garbage and discarded tires.

I'm not against any of this, just when you mandate things you need to ensure support for the long term. 5 years is NOT long term. My newest tractor is 7 but my newest car is 20. All paid for and might last me to the end.

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.

I don’t like to criticize brands; most are outstanding with current models. But LS has a history of tier 4 emissions problems that far exceeds other brands. Hopefully the current models have addressed these issues.

I have a 2014 New Holland Boomer 37 that has had problems since almost new with the regen process, spent nearly 5K at the dealer before doinjg a total delete last fall......... its an excellent tractor now. then I have a 2015 New Holland T4-75 and have had zero problems with it so i think it's one of those some good some bad things... I'm hoping the newer tractors have most of the bugs worked out by now....

Do you think that tractors that are manufactured overseas for a worldwide market will have special engine and ECM modules modified for what could be a temporary change in U.S. regulations? There are no CUTs or utility tractors manufactured in the U.S.
