I suspect that Mike McCain originated the idea of the elephant trunk spout on tow mixers. He is certainly the first person I ever saw using one.
If you have a large enough innertube to use, you can make the trunk really long. Then the trunk itsef can simple be lifted up above the upper rim of the tow mixer tank. When the open end of the trunk is that high, it acts as a shutoff valve. The mix simply cannot flow uphill. To open the mixer to let it drain, you simply lower the trunk down to the ground.
As long as you have a quality seal where the trunk meets the tank outlet, you should have no leaks at all.

Don't know about the length of your blade. I think mine is 24 or 26 inches, the longest ride-on mower blade I could find. Next time I make a mixer I will definitely do the elephant trunk thing. I am now using a 8" pipe with a soccer ball that I inflate in it and deflate when it's time. Do you live in MA?
