Exhaust pipe/tubing

Hello all,

I want to add a small vertical exhaust stack to my SS12 with a Tecumseh HH120. Is black iron pipe suitable for the nipple and 90?

Any type of sealant recommendation? Maybe a jam nut?

I'm guessing it'll have to be braced or supported, where do y'all recommend supporting it from?

Thanks,
bobcat2

Black iron stuff is what I use. And brace where you can. I didn’t use any sealant. Mine have been on for years. I like the look. All my Massey Ferguson’s have stacks. MF 7, 12, 14.

I started installing forward facing exhaust systems. The farther away from my ears that noise is the better.
Definately the way to go Chris. My Cub diesel had the muffler going straight up. Was getting the stink and heat from the exhaust as well as as having to watch it so not to catch it on a big limb or something. Turned it 90° to the front. Got rid of the stink, heat and lot of the noise. Not all trees are perfectly round or grow straight up so no vertical stake to catch them. Personally, stacks on a GT make them look like toys. Big boy wanna be's.

One of my lawn tractors years ago, I had the exhaust pointed toward the deck. My thinking was the vacuum from the deck would suck in the exhaust fumes, mix it with a bunch of air and go out the chute. Worked great. No fumes. The exhaust normally came out the side, at the front and seemed to be allways smelly.
Now this downward pipe was not right at grass level. It was only pointed toward the deck. But once when I was cutting a field which had not been cut all year and it was very dry and hot, the exhaust set the long dry grass a fire. Luckily we got the fire out. Melted a few wires on the tractor but was still able to use. Fixed the wires and the tractor is still operational. This was 15 years ago. And now, this tractor has a stack. Which has been there for years.
And another thing about stacks, they fetch up the spider webs, before the spider web gets fetched up on you.

Bought this tractor new in 1993.

I can't do a stack here because of trees with fairly low branches. I had to build both the exhaust setups on my MF GT's and both come out the right front and discharge down. Don't ever seem to get fumes with these non original engines set up that way. Should be able to see them in this most recent pic.

If you do a stack, make sure you put a brace underneath to support the stack. If not, the weight can easily break off the exhaust port on the head.
