Vertical Exhaust

[TractorTucker]

Since my 2n has a through hood air cleaner, I am thinking about putting a vertical exhaust on it. Does anyone have pictures of one or a reason on which one is
better? Also, my manifold has been cracked and welded. It seems to run fine and doesn't leak so I think I will just leave it be.

I think Henry Ford had it right.
Send the exhaust out behind you so you can enjoy your work day in the fresh air.
An exhaust pipe a few feet in front of one's face sounds like a long, HOT day.
Just my $0.02. You asked for "reasons' and that is mine.
Have fun!

Take the vertical exhaust 10 to 1 over the rear exhaust. After working for a couple of hours, the PTO shaft so hot you had to wear gloves, same with lift arms and sway bars. I installed a vertical on my 53 NAA and have no problem whatsoever with smoke, smell, heat or any thing else from the exhaust. The exhaust actually goes 3 feet above the end of the pipe at 1500 rpm and never reaches the open operator station.

I built my own vertical exhaust because I didn't like having all that exhaust blowing in my face when I was hooking up implements. Not to mention I like the looks of the vertical exhaust.

A little advice from my experience:

Just go ahead and spend the money up front to buy the kit. You will have just as much wrapped up in your DIY as purchasing the kit...unless you just enjoy tinkering. That's why I built my own, and why I build most of my stuff myself, just because that's what I like doing and that's my hobby.

From the muffler up, I believe I used 2 1/2" conduit. I love the way it sounds, and the way it looks but there is not enough updraft. My 2N has a lot of blow-by (as seen in 1st and 3rd picture); couple that with the oversize exhaust (less updraft), means the lovely half burnt oil smell settles downward and directly on me thus making me smell very heavily of exhaust after even a short stint on this tractor. So - stick with the stock exhaust diameter. When I originally built my vertical exhaust, I had a rain cap on it. There was not enough updraft to stand the rain cap up straight, even at full throttle, which pushed the exhaust back down on me even worse. So now it is just a straight stack with a vegetable can on it when its parked. The 4th picture was just a brisk morning startup.

If you use your tractor as a tractor - mowing pastures, haying, farming...stuff in larger spaces - go ahead and put the vertical exhaust on it. If you are using it to mow your yard or anything around/under a lot of trees, leave the stock weedburner exhaust - you and your manifold will be much happier.

Agreed.

Having used both, I much prefer the horizontal exhaust.

It's very easy to add a deflector to the horizontal exhaust to deflect the exhaust to the side and down.

Heat and fumes won't be an issue as long as you stick with the stock pipe diameter so it will push the exhaust up and out over your head. Also, just like a chimney on a house, make sure the top of your exhaust is at least head level or above.

As carpetfarmer indicated the vertical exhaust can be a disadvantage when working around trees. Since I use my 8N on a bush hog to maintain the fence rows, the lane to the woods and along the drainage ditch bank, I use the horizontal exhaust.

I believe the original purpose of the vertical exhaust was to prevent fires when harvesting wheat, oats, etc. Dad would put the vertical exhaust on when using the 8N on the combine. When the harvesting was finished, the horizontial exhaust was installed until the next years harvest.

Mine had a vertical on it when purchased. Wife complained I stunk of exhaust every time I'd come in from using the tractor, so when I restored it, I went back to horizontal. Never set any weeds on fire, and didn't have a problem with PTO or lift arms heating up. I held my breath for the 30 seconds it took to hook up the right hand lift arm to an implement...

Bingo.

I routinely drive near and beneath trees. Vertical exhaust systems simply do not work.

Get a diesel. It stops all the complaints of stink from a gas tractor. Thats what I did

Diesels stink a whole lot more than a gas rig!

I put a vertical on our 8N after the 2nd or 3rd time my son destroyed the horizontal exhaust when brush bashing.

I used the kit from this site as of about 5-6 years ago, and its worked out just fine. the rain cap is hinged on the forward side, and the exhaust has no trouble keeping it wide open.

only down side is, you have to be careful to keep your alternator wire away from the vertical pipe

 

[Ultradog MN]

Amen brother!

 

[8n13325]

I use my 8n on my tree farm and horizontally it was an ignition source in the bush.
I switched to vertical asap.
Depending on your terrain and vegetation.

I eventually did, too:

The Boomer 8N exhausts underneath and diagonally to the front-right, so other than a whiff at startup, is unnoticeable.

Horizontal for me, I'm not a fan of stinky exhaust blowing in my face the whole time. I'd rather deal with it for the short time it takes to hook up an implement.

 

[HFJ]

my N came (to me) with a vertical exhaust. it didn't take me long to switch it back to horizontal.

would rather shut the ractor off before hooking up an implement.

 

[wallytoo]

i have both; the 2n has the original horizontal, and the 8n has a vertical.

i prefer the vertical. i don't smell the exhaust, and i run a splitter at the 3-point, so not having the exhaust right there is nice.

Horizontal is like a built in safety feature.
If you are conscientious about the air you breathe, then the horizontal exhaust calls for the engine being off when hooking up . . . which is what I do too.

Here's my vertical exhaust

If you drive in the woods, you don't want vertical. hurts when the branches snap by the pipe. Trust me.

I am swapping to a vertical stack.
I noticed the hydraulic plumbing was on exhaust pipe and hydraulic fluid was heating up artificially.
Tree farm has brush high enough to make ignition possible too.
I will fabricate a spark arrestor with smallest hardware clothe I can find.
Use a muffler designed for torque, straight pipe for horsepower.
Flapper...

Try again to post a photo.
Just found modern view wasn't on.

My 9N had vertical exhaust when I got it. Changed it out pretty quick when it got bent a couple times when mowing under trees and around bushes. Never regretted it.
