Noisiest PT Ever

Hey there Bill,

If I decide to leave the cab on year round. I plan to put in a small console with 12 volt plug in's and some extra toggle switches for extra lighting. The 12 volt adaptors could be used for a plug in fan during the summer and a heater during the winter among other things. /forums/images/graemlins/ooo.gif

The soft cab idea is a good one as long as you don't turn your baby over. I would worry that it would keep me from jumping clear in that situation. I read somewhere someone had a JD or Kubota and bought a golf cart soft cab and rigged up some tubing to drape it over and it worked great. You might want to check into that also.

You are probably hearing the sound of the exhaust from two directions. One path direct, and the other path redirected. If you remove the rops, you will notice a difference, but the rops is there for protection. You should line the bottom of your rops with sound absorbing material. A layer of foam might be enough to dampen the noise. )</font>

J_J, I went out a bought some foam from an acoustic engineering firm. Don't ask me what it is, but it seems to help. The sound is very different now and muffled. While wearing my ear protection/radio I can hear the radio much better and at a lower volume. I also got some Dynamat and put it on inside the engine compartment on the solid sections. It is supposed to dampen the vibrations in the metal. I actually did this first, and put some under the ROPs. I could not actually see a difference from it. I then covered most of the under ROPS with the foam. I have attached a picture.

One word of caution, the foam had some dust in it. I seem to have caught a cold from the dust, unless it's just a coincidence. I have since blow off the dust. I hope I got it all.

So the under ROPS foam was a good suggestion. My thanks to Clint Blake and J_J.
