Tier 4 emissions

[TractorLegend]

....would be a reason I would be discouraged from buying a new model tractor. After-treatment system (soot filter) EGR valve- NO THANKS!
These are a big dollar source of trouble for many people with late model diesel automobiles and trucks.
I'm not sure when they go haywire on a tractor, like on many autos, if they also derate the power via computer controls so you're forced to fix it.
I'm not sure the logic Big Brother applies to requiring this on such limited use equipment as a tractor or a diesel powered generator.
Saving babies and unicorns, I guess. At the consumers expense. Rant over.

For what it is worth, I have heard that the new tractor engines are far more reliable than modern diesel vehicles, I guess time will tell.

I'm all for turbocharging and direct injection! :~}

Maybe the hot rodders will help out with programmers, like they did with diesel pickups.:confused3: 445A

I can believe that about the engine itself but the after-treatment systems are still in the experimental stages.
The trend, by nature, makes things more complicated to work on and own. Leaving the door open for proprietary diagnostics and software updates (such as on land rovers and many others) that tie you into repairs at the dealers.
I don't think these emission controls couldn't be computer controlled.
I'd be interested to hear from newer tractor owners who have Tier 4 and a some hours on their rigs if this has been trouble free?
Is there now a Check Engine Light just like on autos? Is the power programmed to be reduced when there's a particle filter system trouble or check engine light event such as on a 2008 Dodge diesel?

I couldn't disagree with you more. The cost of emissions with Tier 4 is shifted to the owner operator, where it should be. It is unfair to leave the cost to the general public in having to consume an owner/operator's pollution. Take a look at the effect of diesel soot emissions and that puff of black stuff doesn't look so good anymore.

Everybody wants to say, "But it's just little old me with my little old machine" but the problem is that there a million "little old me(s)". Take a peek at Bejing or Shanghi China and you should get the point. Any of you visit Los Angeles in the 1960's vs now? You couldn't see three blocks for the smog back then and now the air is relatively clean.

Yes there is a cost to Tier 4 but rather than pi$$ and moan, be happy you're delivering clean air to your neighbor's baby. I don't know they had Unicorns in Washington State

I should clarify- I do see the want and need for tighter emissions on automobiles due to the sheer number of them and miles driven. They represent a huge share of emission output in this world.
A limited use farm tractor- we've made great strides even in the years just prior to Tier 4.
Why isn't that good enough considering the limited number of hours operated and globally how few people own them?
We now have the healthiest unicorns in WA thanks to adopting CA standards... lol

I agree something had to be done about deisel soot. They've come yards in the improvement scale, and with teir 4 they're trying to go another inch, and it is killing mileage and the economy . $10000 repairs are not uncommon on the newer big diesels . What small business can keep absorbing those hits? A lot of people aren't buying new because of this( hurts economy). Prices of reman engines have gone up considerably as people rebuild old stuff.

I own a M7060 tier 4, it's pretty simple (so far), at certain time intervals a light will come on indicating its time to Regen. Choices are put it in neutral and it automatically increases engine speed and when near complete the rpms are automatically decreased. The second option is to push another button that starts the Regen cycle once engine rpms are satisfied while continuing to work. This machine has 275 hours on it and I am very satisfied with it and have no reservations with the tier 4

Diesel Exhaust:

1995 California Numbers
On road diesel engines produced 15,680 tons of particulate matter
Off road diesel engines produced 9,820 tons of particulate matter
Stationary diesel engines produced 1,400 tons of particulate matter

Your tractor would obviously be included in category two, off road diesel engines. Why is particulate matter from diesel engines particularly dangerous. They contain Polycyclic Aromatic Hydrocarbons a proven dangerous substance and nano particles which invade lung tissue much deeper due to their tiny size. Infants and children are more seriously affected by this due to the relative smaller lung tissue volume. Studies have proven that PAH causes lung cancer. All credible health organizations agree on the risk and damage of these pollutants.

I posted the 1995 numbers to show the volume of particulate matter early in diesel emission control systems. No doubt these numbers have fallen dramatically and will continue to fall with more vehicles covered and better systems evolving.

You have no right to create dangerous pollutants that affect the lives of others. Doing that is simply a form of trespass, serious trespass. You have a duty to do your part to prevent this problem, even if it costs you money to do so. It's called the total cost of operating. Sure it would be less expensive for one to dump used motor oil into the ditch and drain ethylene glycol on the ground. That simply shifts the cost from the person using the oil and coolant to everybody else and that is not a fair deal.
