Forward Exit Horizontal Exhaust??

   / Forward Exit Horizontal Exhaust?? #31  
Older gasoline engine tractors were notorious for setting fires, especially if the muffler was removed (it served as a spark arrestor). We had an Allis-Chalmers B that set multiple wagons filled with hay bales afire before we learned our lesson that it's place was on a hay rake, half throttle where it didn't spit out flaming carbon. Dad reluctantly re-installed a muffler on our Farmall H following a couple fires - it was our most common hay hauler in the late 50's early 60's. None of these had horizontal exhausts but the fact is that gasoline engines (and I'm talking of 30's, 40's, & 50's) were notorious fire starters. Diesels run a cooler exhaust because of improved efficiency - more heat is converted to work on a diesel, thus lower exhaust temperature and reduced tendency to start fires. We started our shift to diesels on our farm in 1956 and away went the burning hay wagons. We never had a gas engine tractor with a horizontal exhaust but I assume the same hot spark issue under high power load would exist.

I have a forward pointing vertical exhaust on my open station Kubota M6040. Never bothers me. Sorry - just noticed you are asking about horizontal exhausts. I would guess they are not a problem either. But take a look at the picture of mine. Vertical with a tip that directs the exhaust gasses horizontally. Whatever - in use the exhaust gasses are never noticeable. View attachment 694001
I have a 2yo Massy with a horizontal front opening exhaust. Not a problem. Smelled exhaust once in 2 years.

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?
We have 2 with the "sideways" pipes--seldom notice the exhaust. You could put an extender on the sideways (or vertical) pipe to deflect the exhaust out further it it's a concern. Diesel smells better than gas, to me, anyway....:)

It can very well happen. Mostly with the newer tractors with emissions, when it starts the regen process.

We have had big fires starting because the tractors started the regen process during brush mowing in forests with dry brush.
Regen? Heck, my Mahindra has no such function. Tier IV but no regen, no DEF and no wild fires . . . That's JUST why I bought it - 'cause I was so worried about setting the woods on fire. OK, OK, maybe there have been cases - Like catalytic converters and leaf piles don't mix well. But, regardless, like most things, a little common sense goes a long way: Don't park on piles of leaves, grass, hay, etc.

My tractor has a front exhaust and, when standing in front, sure, the exhaust is noticeable. But, I don't recall it being a problem while operating the tractor. Still, it would be cool to have a nice, shiny chrome exhaust stack with one of those rain caps bobbing up and down. That way, I could see all them sparks flyin' out!

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.

I just spent a few weeks cleaning out some commercial chicken houses. Move slats, clean poop. Move slats back, then others moved on top of those, clean poop. Then go back and reset the slats back. Used an old tractor with the exhaust broke off at the hood. Never have sinus trouble but I do now. I. can blow a double handful of snot at any time on demand. Been messed up for weeks now. Get the upright exhaust, heat rises. If you're afraid you'll break it, incorporate into some protection. Our skidder has the exhaust in one of the runners from the grille to the top of cab. Can't say it will last, but it was bought new when Jimmy Carter was president.

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.

We have a JD backhoe with a factory forward exiting exhaust, below the front "grille" area. I do get a whiff of exhaust fumes occasionally, but not really much different from other open station rigs I've used. Now, if it had regen crap on it things could be different.

ust & I converted to vertical do to exhaust fumes using my log splitter & I'm glad I did! If your not using a aft mounted implement that requires to stay at the rear of the tractor while it's running than your okay going horizontal

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 )
