B2150 exhaust

KCB · Apr 10, 2000

Has anyone tried relocating the exhaust stack on the 2150? I have a lot of dogwoods with low branches that tend to get caught by the exhaust pipe and then whip me in the face as I continue. Not a very pleasant experience. I could deal with them brushing by my face, but the whipping has gotten old fast. Is it possible to rotate the stack 90 degrees where it connects to the manifold, towards the front , so that it's parallel to the engine? Would this put too much stress on the mainfold? I'm guessing that if the exhaust tip is anywhere near the front, the radiator fan would blow the exhaust fumes away from the driver. Anyone have any suggestions?

I don't know about the 2150 but the B7100 (1995 model at least) came with the exhaust horizontal to the front, but had to be rotated 90 degrees (straight up) when they put a front end loader on it, so if the bolt holes line up, and you don't have a loader or other implement in the way, there should be no problem. And if you're pushing into limbs solid enough to whip back and hit you like that, you may break the exhaust off some day if you don't change it. Twice I pushed into limbs with my B7100 and the engine died, and I discovered a limb had whipped back into the throttle handle fast and hard enough to shut me down./w3tcompact/icons/smile.gif

Take your muffler off and take it to a muffler shop. Tell them what you want and they'll weld a 90 degree bend into the exhaust pipe. This shouldn't place an undue amount of stress on the exhaust manifold since Kubota uses this design on other models. If you are concerned that it may cause stress you can run a brace from the tractor to the end of the muffler.

Yes,this exhaust is made to run in either direction,only need to trim some off the exhaust tip.There is no need to reinforce anything.Only hang-up is if you have loader,a small portion of the loader frame will be black from the exhaust.

I broke off the vertically oriented muffler on my B1550 on a low hanging limb. The replacement cost over $100 -several years ago, probably is more now. I put the new one on horizontally facing forward - works fine - the only disadvantage is the occasional whiff of diesel exhaust in the face. Some might think that's not a disadvantage- I go to "Bike Week" in Daytona every year and the smell of exhast fumes and burning rubber in the air adds a lot to the experience.

Hi JBM.
Horizontal mufflers do have there advanages.
Very seldom gets broken off from low objects and keeps the insects from nibbling on one if you don't mine the smell of the fumes also keep the weather from entering.
I'm a firm believer a tractor should have somekind of muffler stack if there a front loader,also in the past a horizonal muffler doen't help the paint.
With a vertical muffler the fumes aren't as likely to enter the engine area where the air filter located.

Have fun and stay safe.

I moved mine (B2150) a couple of weeks ago and attached a short(~7") 45 degree elbow on the end. This blows the exhaust diagonally outward across in front of the radiator and towards the right. The radiator fan helps to blow the exhaust away from the tractor. I tried turning the exhaust tip several directions and this seems to work best. It was very simple to do. So far no problems with the loader and It's sooo much easier to mow around those dogwoods. Thanks to all for their input.
