Mahindra 2015 answer to EPA TierIV regulations...

[woodchipper]

Hi all,
Upon reading litterature on Mahindra tractors, I came across their buletin: mCRD.
Once decifered, I beleive it means mutlty port comon rail direct diesel fuel injection. And in conbination with a clean EGR system, and a catalytic converter they call Diesel Oxidation Catalyst (DOC), Mahindra seems to be well positioned to respond in a very inteligent manner to those much controversial environment laws forced upon us by the governing body that we all refer to as the EPA.

Is this not so new technology put up in this new package, the best Tractor Owner answer one can get about this hole mess of complying to the Tier IV restrictions??
To my own eyes, it looks to be the best system put in place by any manufacturer up to date. As per my understanding, you get better fuel "mileage", no DPF filter to fill our dumps with, no down time because of the regen mode so often required, no additional fuel and parts cost and husling, etc... And I am sure these engines will be less noisy, with less vibration, and of course less pollution in the end.

What do you all think?

It sounds like another name for a passive DPF system...

I believe DPF filters are rated for several thousand hours. I have 700 on my current tractor in 10 years so I might go thru 1 filter change in my lifetime if it had the system. And you can keep working during regens to my knowledge. (only time I think that would apply is if filter is really getting plugged) Everyone made this huge fuss when they came out with this on pickups, I had one for 3 years. Wasn't a big deal! (and getting rid of it had nothing to do with the emissions stuff)

Plus its not going away.

Yup sure, that's why all these 09 up VW TDIs are coming in with bad DPFs. Junk pure and simple.

Several thousand hours my rear end, Fred

The DPF on the new VW's state 120,000 miles to be serviced. Numerous people are over that with acceptable ash loads. The only thing that would need to be done is remove the ash. VW did not set up their DPF's to have the ash removed. Usually the ones with problems are the vehicles that had a problem that was not addressed.

The company I work for is going to a Caterpillar engine with catalyst for the orchard elevators we manufacture and we will be dumping the Deutz 3 cylinder engines. No regen or DPF on the Cat. Thank God to, those Deutz are dirty engines for sure. B.

Aggressive egr allows a bunch of soot back into the intake. I'd take a dpf/def equipped tractor over that anyday. The soot accumulates and can cause problems. I did however rush to secure a tier II deere for my personal tractor. I have a '13 powerstroke and haven't had any problems what so ever out of is emmissions system.

$1000 for a re-manufactured DPF from VW not including the install. Also must replace the EGR filter.

You go buy one and tell us after 150,000 miles how you like it.

And when the Urea pump fails you can spend almost another grand to replace that.

Tier 4 lovers can have at it as far as I'm concerned. I work on them for a living, do you see me owning one? NOPE!

Last weekend one of the state plow trucks sat on the side of the road 45 minutes waiting for his DPF to burnoff, another accident waiting to happen and more failed EPA BULLcrap.

By the way your 13 Powerstroke urea pump costs $700 to replace and are failing at just over 60k miles, ask any Ford technician. I hope you bought the $5,000 dollar ford customer care contract because you will need it.


Regards, Fred

I don't like any of this. mCRD is what I was talking about. I'd rather have a def equipped piece of equipment over one that has very aggressive egr. I just bought my tier II tractor in nov so keep from having a tier IV. I have an extended warranty that will hopefully cover anything. If it doesn't, I'll have it deleted within a week.

Yeah, have you looked under the hood of a new powerstroke? You can't see the ground from under the hood that's for sure.

I have a 180,000 mile year 2000 7.3L Ford Powerstroke that has zero emission equipment, the only thing on he exhaust is a muffler and that's from the factory.
I plan on keeping it for as long as possible to avoid a new diesel.

Just like anything... The more parts, the more parts that will fail.

Also have a 2005 Case DX33 and I believe it is also free of all the emission crap, not sure if it has an EGR but I don't think so. A little black puff out of the exhaust on start-up doesn't bother me.
I looked are at the new Kubota's but couldn't justify the extra money for more headaches so I bought the cleanest used tractor I could find.

I hope the new tier IV stuff is problem free but I don't want to be the guy to test them out!
