Need for Muffler Fluid.?

BushogPapa · Oct 31, 2015

I have not been hearing anything about this..I see that SOME New Diesel tractors do not need or use the stuff...

Mahindra, for example...

Is that a sign that soon non will be needing it and will that obsolete anything "new" we have already purchased..??

What do you se going on..?

The Mahindra Diesel engine is called a "Tier 4" does that shed any light..??!

There's links to plenty of articles about different tier 4 engines on the attached site.

ALL new off-road diesel engines sold in the US must meet "Tier 4" emission standards.

Diesel mfr's have developed 2 ways to meet Tier 4. In very simplified terms:
1 - Cooled exhaust gas recirculation, particulate trap and selective catalytic converter (SCR), or
2 - Urea (DEF or "diesel exhaust fluid") injection + diesel oxidation catalyst + SCR.

Consequently same as on-road diesels, you will find some tractors may require DEF while others do not.

Note each scheme has advantages and disadvantages around complexity (hence cost), fuel economy, exhaust outlet temperature, sensitivity to long periods of idling, requirement to periodically replenish the DEF tank, etc.

Fortunately Tier 4 diesel emission requirements are not retroactive to existing engines - at least not yet...

ALL off road diesel engines must meet the same nonsensical EPA regulations.

Some manufacturers have inventory built before the latest regulations went into effect and/or nonsensical credits that they can use for the time being.

If you want a new tractor above 60 HP that does not use DEF buy it NOW! I just did.

If you want a new tractor below 60 HP that does not use DEF buy it soon.

If you want any diesel powered equipment, even a lawn tractor, that does not use DEF, pay attention to the ever-changing EPA regulations.

The EPA cannot and will not leave anything alone unless and until it is reined-in (preferably eliminated).

There are still a few so-called "interim Tier IV" machines that have not yet been sold. Such machines are currently in demand, going fast, and will soon be gone, whether manufactured by Mahindra or others.

I just bought the last Kubota interim Tier IV model of my choice yet available in the United States. It was delivered yesterday. The model that replaces it uses DEF, has different sheet metal, a different model number and a few other trivial changes. It also costs approximately $8,000 more. The model sold before the model that I bought had no DPF and cost approximately $5,000 less. Shame on me for not paying close enough attention to what the federales were doing a couple of years ago.

The prices of used, low hour, non TIER IV (interim or otherwise) tractors are increasing rapidly.

Thanks feds.

Have you considered purchasing one of the new Volkswagon line of tractors? I've read that they guarantee that their tractors will never fail the most stringent EPA standards, on or off road. I have to give them credit for their thinking outside of the box efforts and ingenuity, not to mention technologies to pull that off. Grin.

On your last sentence they are if you live in California. Must be state law because our 1984 Ford L9000 dump truck has a exhaust filter. The engine is a Cummins 855 350 hp Big Cam. Nice box hanging off the side of the frame were they can plug in their emissions testing equipment too. Also saw an 1989 IH dump truck with an aftermarket exhaust filter.

Dean,
I grew up on a dairy in northern Indiana. I had a lot of seat time on diesel tractors, 50-60's. I don't know why, but today I can't get within 100 feet of a diesel without instantly getting a headache. If a smoking diesel truck passes me, I have to get on the brakes and put distance between me and the smoke.

So, I'm glad the EPA is cleaning up my air. Even the cops are handing out tickets to some for excessive black smoke. Consider yourself lucky if you don't get a headache.

I would love to buy a new small tractor that wasn't diesel. Instead I have to use antique tractors. Which I don't mind. Love my mother's old farmall C and Jubilee. When I was looking for a sub-compact backhoe the only gas ones were allmond and terramite. So I settled for a terramite.

I know this isn't popular to say, but I'm glad the EPA is cleaning up diesels and hope some small engines go back to gas. Then I might even buy a Kubota.

Before I get kicked un the rear, I know others who can't get close to diesels without getting a headache too.

Diesel smell gives me a headache too, it got a lot better with low sulfur.

GreenEnvy · Nov 1, 2015

Well I have asthma so I hope the EPA will start putting the clamps down on any farmer that makes dust. That is what you sound like to me.

The majority of diesel engines are used in urban areas, where pollution is still a major problem.

I'm mildly sensitized to diesel exhaust. I can't follow certain years of Volvo truck with a Cummins engine. Don't know why but their exhaust is quite rank and makes me sick.

That being said, I don't really care what you do to your truck, as long as you're not blowing large amounts of unburnt fuel out in my face.

Its called DF and ex fluid

I'm thinking these new regulations are making the diesels fumes harder to tolerate. I have been stuck behind some recently and there is no smoke to speak of but boy there sure is something that burns your eyes.
