Mitch: I wouldn't look very hard for a rain cap especially on small gas engine tractors. Half the time in heavy rain you look out your window and wind has the rain cap open and is actually deflecting more water down the stack than if it were just an open pipe. Often times a tractor parked near a building will get down draft deflections causing a lot of water to go down the stack.

If your exhaust is tight and tractor is out in the open, even in a 2" rain fall over night you will get very little water down the stack. The important part is that it is started the next morning. The only time I ever cover tractor exhausts is if the tractor is going to be parked for more than a day. The old soup can is still the best insurance against water down the stack. Keep the can very little larger than the stack so wind wont blow it off. I keep a sized soup can in every tractor tool box. In fact I had the same soup can in my 130 for about 10 years now. Had to replace it last week as it had a hole rusted in it.

The other matter I found over the years is rain caps don't last very well on gas engines. I had them on big diesels and they lasted 5 to 10 years. I once put one on my SA and it burned the outer edge of cap off within the first year.

Remember if the soup can is sized, it is virtually water proof. In fact the only time I ever had problems with water getting in the tractor exhaust was a loose pipe where it entered manifold on my Farmall 300. That was clearly water running along the hood and following the pipe. The exhaust actually had a soup can over it.
