exhaust on diesel tractor?

Anonymous-0 · Jul 7, 2010

Hey folks,
Aside from cool points, is there a disadvantage to running the exhaust under and out the back of a tractor instead of the stack?

I don't do crops, but was pulling a heavy tank after dark once and had a fireworks show from the stack. Was wondering if that would be a problem with hay making.

Stack gets caught on fruit trees and looks a little drunk at the moment. Don't know what would be the greatest danger though.

Thoughts???

Main reason for the vertical exhaust is breathing. A hard habit to break.

That "fireworks show" is heat being expelled (amomng other things) Under-slung exhaust puts that heat right under your feet. Makes for an unpleasant experience in hot weather.

Exhaust out the back can make for misery when hooking up an implement.

Then there's that issue of setting hay/weeds/ect on fire.

Personally, I'd MUCH rather have the exhaust fumes and heat going up and over my head.

I guess you need to weigh the options yourself. For your trees, yeah, you will like it better underneat. And haying is not real hard work so I wouldn't expect to start a fire. Unless the wind is contrary I have never found exhaust gas to be a problem on an open tractor.

Had a frind who's hired guy burned up a brand new Deere when hay caught under the tractor and was set of fire by the exhaust.

11 bazillion N Fords had exhaust underneath. I ran one all the time as a kid, don't recall any problems. We hayed with it, never set anything on fire.

Had a couple of MF 135's and hooking to 3 point
would make my eyes burn. Like has been said it's
hard on the breathing too.

Under the running boards is hot on your feet and a stack blows heat in your face, diesel really should not be a fire hazard at all.

The diesel fumes are a lot more toxic than the gas fumes from the old gas tractors. Had a customer one time that had a canopy. His muffler had an extension to put the fumes above the canopy. That extension rusted out. He just put the rain cap on the muffler ran it with the fumes going under the canopy rather than over. He passed out one afternoon mowing hay. He had to spend several days in the hospital with carbon monoxide poisoning.
I would not put a down swept exhaust on a diesel.

It also can be red hot carbon that is expelled from the exhaust system when you work the tractor harder than usual. I don't know if all diesels coat the insides of the exhaust with carbon, but my 641D Ford sure does it, especially when I am just using it for light work. When I plow with a moldboard plow, I expect to get lots of sparks out the vertical exhaust. The sparks have actually started a couple of grass fires, so I am really careful about using that tractor in the very dry times of the year.

I have seen lots of Ford gas tractors with exhaust out the back, but I have never seen a diesel model with anything but vertical exhaust. My guess is that most people prefer to have the stinky diesel exhaust blowing away from where they are, at least some of the time, rather than having to smell it all the time since it is ending up right under the seat.

Don't wanna git in a pi$$ing contest here! I've worked with diesel tractors for 50+ years using both vertical & horizontal exhaust, and can say that either system works fine! Its all a matter of personal prioritys/needs! Both have advantages and disadvantages, and as far as engine performance goes, either system is OEM on most diesel tractors!

Exhaust out the back is very annoying. Most of the tractors around here that had it have been converted to vertical exhaust.
