Buying Advice Diesel smog emission stuff?

[5030]

Basically with the exception of common rail, high pressure injection. Problem is every manufacturer uses the least expensive components. Sort of like the Takita air bag scenario. No manufacturer wanted to adopt T4, the EPA forced them into it. Same with Europe but a different EPA. I believe in Europe is TUV or something like that.

I'm also guessing all the electronics are there mostly to make the tractor meet emissions standards?

Not entirely. My pre-emissions
diesel truck with common rail 5.9 Cummins has an ECM.

I have a Deere 4044M. It needs to run at 1500 RPMs or the regen will eventually kick in. The only issue I've had with it is that my father in law borrowed it having no clue about the regen feature for the diesel particulate filter. He mentioned that it ran louder than normal... and he shut it off. When that happens it can sometimes be difficult to get the regen to complete. I was due for service at the time, so I let the dealer handle it. When it goes into regen mode the tractor must maintain 1500 RPMs until it senses the filter has been cleaned off. Mine very rarely goes into regen. I did have to let it run 15 or 20 minutes until the regen was completed after I was done working with it a couple months ago. I would much rather have the regen feature than have to add DEF.

Rich,

You should get a tractor that can do the work and tasks you want to do, in the time you want to do it in.

If you're buying a 25hp tractor only to eliminate emissions, but in reality what you need is a 40-50hp tractor for the work and attachments you have, how is that a good idea? you'll be back trading in and trading up in hp before you know it.

Buy the best fit of equipment for the work you need done, and hang all this worry and wort about the emissions stuff. Most folks have no trouble at all with theirs. Just run it like you're supposed to, keep the rpms up, and keep the filter hot.

Exactly! Buy the tractor that best suits what you NEED and be willing to WORK it. Buying a 50 HP tractor to pull the kids around in their wagon will ensure that the tractor sits at the dealer getting repaired.

Well, regarding DPF's, Mahindra does not use them on the majority of their tractors. From a vendor site:

IS IT TRUE THAT MAHINDRA TRACTORS DON’T HAVE A DPF (DIESEL PARTICULATE FILTER)?​

Nearly all of Mahindra’s tractor models in their Compact Utility (series 1600, 2600, 3600, and 4500) and Utility (series 5500, 6000, 7000, 8000, 9000) lineups do not have diesel particulate filters. This is because Mahindra’s mCRD engine eliminates the need for a DPF and never requires high-temperature burn-offs, which is a maintenance task that often gets forgotten by owners and tractor operators.


Might be worth considering. The series listed above, run the gamut from 26 HP to 71 HP tractors (1600 - 6000 series). Cheers!

There are different ways to achieve T4 and Mahindra chose to use a bunch of EGR.

^^^^
And the overuse of EGR typically results in a massive buildup of carbon and soot over time in diesel engines negatively impacting engine performance and efficiency.

I seem to recall Ford had issues with one of the versions of the Powerstroke. A friend of mine said you had to remove the egr and they were fine after that.

Considering Mahindra's size 15 footprint in the global tractor market (top tractor seller in the world, by volume of units sold), I don't see this as an issue. That article was published in 2014. Mahindra business has not been impacted by their EGR T4 engine designs yet, in nine years...

Their smaller engines are made by Yanmar, and they have a platinum reputation within the industry. Mahindra still offers seven years on the power train warranty.

Say what you will, but Mahindra's market success, globally, is hard to argue against. If Mahindra tractors, and their EGR T4 engines, were garbage, the global market would chase after other brands. Cheers!

Ford has had issues with every model of powerstroke except for the original IH 7.4L.
