Tractor exhaust pipe modification

[Tachdriver]

I have a new 2655 Mahindra tractor. I would like to have a vertical exhaust pipe with rain cap flapper, I may make one, but has anyone done this or have an ideas ? I suspect I will have to install a SS flex joint where the new pipe meets the factory one

Is it a cab unit? Just asking because a vertical pipe may allow exhaust into cab ac intakes.... just saying

Have only had replacements made but if it were me, if vertical exhaust was an option would like to see that design first. I would fine an exhaust shop who makes their pipes as they should be able to make a pipe to fit the tractor with out flex pipe. As to the top rather have the basically gentle bend and not a flapper on top of the pipe. Of course turn it away from the operator's station or cab. Be sure it does not interfere with hood or front end loader. Depending on how it exits the hood area may need to install heat shield. It will create a blind spot of some size and also something for tree limbs to have fun with.

its not a cab tractor but open one

Out of curiosity, why do you want the vertical exhaust? Congrats on the new tractor.

i want to be cool, like Oliver Douglas

Most vertical exhaust pipes on non cab tractors run directly up from the exhaust manifold, it may take some brackettry to do a vertical not held by the manifold.
Also definitely go with the rain flapper. If you end up with a trap in your exhaust piping you may wish to add a weep hole in the low point.

I'm cabbed (DIY) and my exhaust is at roof level with a flapper valve.
I never get any fumes in the cab so I'm good to go!
Extending is not rocket science, just weld on an extension to the pipe.
You can use flared tubing and clamps ( if you don't have welding abilities), but be sure to add a flapper cap to avoid water ingestion. (or at minimum U can add a 90 deg curve at the top end).

its the units with ac and heat that may have an issue. They have intake vents on outside top of cab.

This guy nailed it, i like it. thanks

Pretty well all ag tractors have vertical exhaust, cab or not. No design issues on those.

Underslung has it's benefits, but using one in a dusty yard makes one question having one. I plan to convert it at some point, but it's nice not looking at a stack.

Farmer495, I agree with your statement "Underslung, using one in a dusty yard makes one question having one." That's my biggest complaint with my tractors exhaust. It blows dust right in front of the radiator which helps it clog frequently. I have made it a practice to blow off/out the radiator fins each and every time I use the beast; even if it's only a short while of use. It just seems to help it stay running cool longer. Often it's just a PITA to do, but only takes a few minutes and I am assured that next time I fire up I'm good to go for the task at hand. Unless it's mowing or working in dirt, then I've got to be constantly aware of the dust blow-up factor.

Blowing straight upwards would be much better for me but my TYM's design makes that an almost impossible task to create. I've got flex tube on the very end and have it blow to the side of the tractor but it still creates dust. Just the dynamics of our CUT's designs.

Mine is low to the front and pointing down. Every time I drive into my barn I blow dust everywhere.

On my M4700 it's on the left pointing up. Every time I drive in the woods it catches tree limbs.

Another thing you can do to slightly modify the direction she is putt-putt'n out is to add a slightly larger than the pipe stainless exhaust tip. Or other such extension to divert it a little. I had a problem with my 2555 spit'n out black oily stuff for a boot a minute when I started her cold.... Vertical exhausts have their own distinct problems. You want them high enough that you do not have to eat fumies all day when the wind is just right and you get to enjoy it when plowing/disking a field back and forth all day. Plus the keep the rain water out of the motor thing. My Jd 2240 had an exhaust pipe exiting under the left rear axle. That was a lot of fun when you were changing something on the 3pt. We tend to think that ' my life would be soooo better if I pointed my exhaust that way ', but usually any way you point it has it's drawbacks...

Just have the outlet above the cab inlets and off to the side helps too....just look at stacks on cab tractors.

i will give you my experience on the flapper slappers - they are rattling nightmare, they also grab branches and hold on vs rolling past a smooth pipe, they also can cause excessive vibration and loosen other bolts/brackets on the exhaust due to the added weight on the top of the pipe and vibration of the engine, if its designed for it its one thing if not i tried adding to my skid steer, backhoe, bad idea. Both have been removed - it may end up costing you more than a 10 dollar flapper!!! - for my big tractors we curved the pipes at the top - works great although we dont leave ours outside and if we do a can goes over the straight exhaust and a stopper goes in the curved ones

Like Searcyfarms, I removed the flapper from the vertical pipe exhaust. The rattle and noise was too much to endure. When I get a "round toit" I'll install a bent pipe in its place.

You don't want a flapper. They end up being a pain. You are much better off curving the end tip slightly and cutting it at a 180* angle and point it in the direction you want..

My vertical pipes have the rain flapper on them,
the only time it flaps up and down is at a very low idle.
If the tractor has any rpms to speak of it doesn't flap against the pipe.
I run with the weighted end forward or sometimes it will get twisted to the side.
Yes it will catch some limbs, but they are going to get me in the face anyways so I am using the clutch to ease thru and catch them with my hand.
