Rolling coal? Lots of soot under load - B2601

[RMS]

From what I've seen on my lx2610 that looks normal. I use Spray Nine degreaser on my loader arms and snowblower to clean it usually when I remove them for the season.

That unit would be torn off by the bush within a few months. I've already broke the tailpipe off of the B2650 twice. The latest welds are holding.

Well, it's been on mine for better than 5 years.


OP, it looks very normal to me.

This is after about 20 hours of digging. I only see the black smoke when I'm have too big of scoop and am giving it max power to try and bust free of the dirt that doesn't want to budge. I would not consider this normal use for most.

What elevation is this? If you've checked the air filter and induction system, you may just not have enough air. I don't know if there's a procedure to adjust the fueling for high altitude.

Did you remove DPF and reprogram the ECU?

Yes for both tractors, along with custom exhausts. And for the record, WAY more soot from the little 3-cylinder BX25 than either the MX or M. There's not a trace of soot from either but the EPA knows best .... yeah right!

Actually soot isn’t the most dangerous diesel exhaust pollutant. It’s sulfur oxide which is a colorless gas. This is why DEF is used to reduce it.

Sounds like you abuse your tractor or don’t pay attention if you are ripping the exhaust off from it.

A Diesel engine (typically) is running without throttle and excess air. It may be that your injection pump needs adjusting (not sure if that applies to your model). If it injects more Diesel than there is air for it to burn you get only soot and practically no extra power. If you can see the soot in the exhaust gas it's definitely too much Diesel injected. Clogged air filter would have the same effect, as mentioned already.

Kind regards,
Hugo

I take care of my equipment. It just has seen some heavy work over 6 years. It's still running pretty much like the day I got it new.

And I don't "abuse" that equipment. I work hard with my tractor and sometimes tough sticks worm their way between the engine and its various parts while I'm checking the rear while backing up. The one that mashed into the exhaust pipe was laying flat then the rear wheel leveraged it pointing up while reversing.
This kind of thing also happened with the RPM sender gauge.

The best would be having guard plates/pans under the 'bota, I know. But they're really costly just like new tailpipes or rpm senders.
Those sticks are no longer an issue.

Neither of my tractors have DEF, and if you want to talk about SO2 emissions do some reading on volcanic activity. When I was working in Hawaii and spending a lot of time in Kilauea during the eruptions, that mountain was spewing out more than 100,000 metric tons per day!!!!

When you consider that there are about 1,350 potentially active volcanoes on the earth not including the incredible number of volcanoes on the ocean floor, with many currently sending all manner of toxic crap into the atmosphere, you start to wonder why the focus on a subset of a subset of a subset. We see this slight of hand in every aspect of life with the "something meaningful is being done" illusion.

Here's the EPA hard at work for us.

The E.P.A. Promotes Toxic Fertilizer. 3M Told It of Risks Years Ago.

More than two decades ago, research from the 3M company showed the U.S. Environmental Protection Agency, or EPA, that sewage sludge, the raw material used for fertilizer, carried toxic “forever chemicals.” Since then, Rolf Halden, a professor in the School of Sustainable Engineering and the...

I don’t intend to get into a political EPA bashing discussion. My point was that diesel emissions systems for larger machines are not just focused on soot as a pollutant.

Soot is the first and primary pollutant regulated on diesel engines. That is accomplished via the DPF or diesel particulate filter. I believe what you are trying to call the most dangerous pollutant is actually Nox or oxides of nitrogen. This is the secondary pollutant regulated by the EPA. Sulfur oxides are not even a concern of the EPA currently, besides any sulfur that would result from diesel exhaust would come from the ultra low sulfur diesel fuel which would bind with the SCR before it is sent out the exhaust.

You are correct. I meant NOX, not sulfur oxides.

I'm well aware of that, but let's not kid ourselves that DPF on small tractors is going to move the needle in any meaningful way. It's a placebo that consumers pay for so that various entities can make egregious claims regarding the betterment of the planet. It's a con just like carbon credits are a con.

The VP of engineering at the company I work for spent decades at John Deere, and he has a tremendous amount of experience with emission systems on agricultural equipment. He mentioned that the contribution to emissions from US agriculture is less than 2%. What percentage of that 2% is from hobby tractors? Less than .0001% I bet.

Volcanic emissions account for a big chunk of global emissions, and what about all of those rocket launches and thousands of aircraft in the sky at any one time? There's a much bigger discussion to be had here when it comes to the planet and meaningful, impactful ways to reduce pollution.

The pollution caused by rocket launches

Rocket launches are an integral part of our 21st-Century world. But how do we stop their polluting exhausts accelerating climate change?

One thing I do know is I can operate my tier 4 tractor all day without a sinus headache. My previous pre-emissions tractor gave me a splitting sinus headache after an hour of operation.
