Forward Exit Horizontal Exhaust??

[Tony H]

Thanks

I am tractor shopping and the reason I asked is the owners manual for my new to me Alamo SHD96 Flail mower says one cannot have an under tractor exhaust that exits to the rear.

Some of the tractors I've looked at have underslung exhaust systems, but I think they could be reversed and run forward. However, I have not run a tractor with a horizontal forward exiting exhaust.y buddies 3000 series knots has a vertical exhaust the exits the side of the tractor (stock setup) I've spent enough time in that machine to say it's not a problem. I was leery the first time I jumped in it. I was pleasantly surprised.

Also on my newer 2018 M-F 1526 it has a mid mount forward exhaust horizontal that there is no problem with exhaust fumes ( diesel )

I think we're all overlooking the big advantage of vertical exhausts on smallish, no-cab tractors. It's a great hand warmer in the wintertime while removing snow. And adjustable, too. The more heat you like, the lower you grab it.

Now that's funny! More so because it's probably true. Thanks for the chuckle.

Question as I only have a tractor with a vertical exhaust stack.

Do forward exiting horizontal exhaust system found on many cause the operator to breath in lots of exhaust fumes?

I remember years ago being on the steerage hoe behind a tractor with a rear facing horizontal exhaust, my answer is definitely forwards.

His main ????? was, Does a forward horizontal exhaust system make the operator breath in more exhaust fumes than usual & most tractor owners that have a tractor with a forward horizontal exhaust do not have a problem with excessive fumes being breathed in. & on my 2018 M-F 1526 that has that type of exhaust i don't have a problem with excessive fumes. & the exhaust exits on the left side at mid point forward.

I have a MF 135 diesel with the exhaust exiting downward under the left rear axle. We’ve been using it for almost 50 years with a rotary cutter and a flail a bit. Unsure of what the issue might be using a flail. Other than getting ‘gassed’ when hooking up an implement. I do prefer the front horizontal exit on my Kubota for that reason.

Must be wet where you live. Here, in dry powder like soil conditions, any tractor work will send billows of powder dust into the air, and settles on the windshield. You’re good for only 10 minutes, then have to get out a squeegee to clean the window. I’ve modified mine so it blows ahead and up, rather than down.... helps a lot and now buying fewer air filters too.

My Kubota L3400 has the forward facing exhaust and I get hit with fumes quirte often. My L2850 has vertical exhaust and no problems. My 364 IH diesel has under slung exhaust and no problems. Guess it is just a matter of preference but if I had a choice I would take the vertical every time.

It’s the only thing I don’t like on my Deere 110 TLB

It's not a matter of common sense. You can't predict that the DPF will regen and what happens if you're bailing? Or you're in the middle of high brush mowing? Things can go south very quickly. That's why they put a button there to cancel the regen process, however some people can miss it due to lack of knowledge.

The DPF does get temps above 1200F, so you can imagine how hot the gases at the exhaust will be. Just for the kicks, my dad's SUV was regenning one time and I grabbed a dry leaf and held it 4" away from the exhaust tip. That thing lit on fire almost instantaneously.

Mahindra claims that their tractors don't have regens, I guess this was a nice marketing move as people that don't quite understand the various emissions systems fell for it. However, they use a DOC, which is technically always regenerating/burning once it gets to the proper temperature. That's why it's very important with this system, not to idle too much and run high RPM, so it doesn't plug the DOC. One system is not better than the other and vice versa.

I guess the regen jockeys should do what the Aussies are required to do: Have a fire extinguisher on board!

Seems to me that having common sense would allow onee to avoid situations like that during regens and to not miss the opportunity to delay them. At least, it would for me.

DPF, DEF, DOC or not, never having to worry about regens (unexpected, untimely or not) or the need to make sure the DEF tank isn't empty or any of that is a huge plus for me.

This whole discussion demonstrates why I wanted to avoid a regen engine.

Plugging up? Ha. I lose sleep every night, tossing and turning worrying about the catalytic converters on my cars, trucks and tractors plugging up.

It must be working, though, 'cause it's never happened. I'll try to keep that whole 'one system is not better than the other' notion in mind but it won't be easy since I never, ever think about it until someone brings it up.

Hi, I have a 1630 New Holland that the exhaust exits on the left side of the engine through a hole in the hood panel, angled forward. It is about mid shin height sitting on the tractor and seems to blow the considerable smoke well clear. Amcdust

Do you have any pictures of your mod you could share? I'm in the same boat with an M62...

Have a new 40 HP Kubota with forward facing horizontal exhaust, and I don't notice fumes at all. The old Ford with vertical exhaust is much more noticeable. I believe the newer diesels burn cleaner too which helps.

I am looking at tractors from the late 60s to the mid 1990s (IH 64/74/84/85 series and their Case IH counter parts) for my new tractor, but not apposed to others.

The exhaust on my Mahindra 4550 side vents about 2.5 ft forward of the brake pedal, well placed for fumes to waft across the driver. A Hamiltonville Farm video on youtube gave me the idea of using an 18" flexpipe to point the fumes lower. That didn't make much difference, so I took a 6' flexpipe to the lower front of the tractor along a path with few obstacles, but the fumes still managed to make their way back to the driver.

Finally I found a path for 7' of pipe exiting behind the driver's seat and that worked great.

That is a crazy OEM exhaust location. Doesn't make sense, almost like they forgot to install the exhaust system!

Good job fixing it.

I have to agree, it looks like they didn't finish assembling the tractor, you've done a better job of engineering it than Mahindra did.

On my 2nd tractor with forward facing horizontal exhaust. Keeps the fumes away while you're changing implements. The only time I've been "gassed" a bit is if I'm airing up the front left tire while the tractor is warming up! Other than that, all good + no worries about rain going down the exhaust into your cylinders!

I have had my MX5100 for over ten years now and the only time I breath exhaust is while driving on the road any distance. I’ve driven it to my daughters house several times over the years and I can taste diesel after the 8 mile road trip. Grew up on the farm driving diesels and none were as bad as the MX.
