I have a troy bilt bronco tractor had for about 3 years. I ran it this past weekend and for some reason it sounded a lot louder. It seems to be coming from muffler/exhaust. I head that gaskets leading to muffler have been issue in past for this bran. Has anyone ran into similar issue?

Which motor do you have.

I have the 18 HP Kohler Courage

For some reason the gaskets on those get brittle and come apart.but its not a troy bilt thing,it was with the engine.

I ripped it apart ove weekend and put new gasket in, works like a charm now
Thanks
