My ZTX5 has a Kohler ZT740 engine. Seems excessively loud to me. This may be normal but just checking see if anyone else had noticed. Do they make anything to help reduce the noise? Wonder if they make a quitter muffler. Don’t know who supplies their mufflers.
Yes that’s it. I have an internal expansion tank. It shows there is a two prong black adapter to use, but, it screws in on the back side. Do you have to remove the wheel ?
