Gasoline shut off valve?

[hillybilly]

Good morning all. At 70 years old, I am the very proud owner of a Husqvarna TS154 X. Not only is the nicest riding mower I've ever had, it's the first one I've bought brand new.
Mine has a 27hp Kawasaki engine.
I'm thinking about installing an inline shut off valve for the gasoline for winter storage purposes. I just wonder if anybody has done this?
More background...I only use ethyl free gasoline and put a shot of stability into each 5 gallon jug I use.
Thoughts?

Even with a fuel shutoff I would still recommend starting the engine and let run at least 5 minutes monthly. This is because carburetor are vent to the atmosphere and as the fuel vaporizes it leaves behind all the additive which can clog up a carburetor. By Cycling the engine monthly you are refreshing the carburetor fuel in its fuel bowl.
