For a small piece of yard maintenance equipment there would be no need for such a fuel valve, just push it back to the shed. A large riding xxxxx is a different story. I would certainly not want to walk back to the shed to get a gas can when I could flip a valve and drive the machine back for refueling. The fuel you use to do a job one day may be more or less depending on the height of the grass or the depth and pack of the snow. I don't live in snowblower country but I can imagine what a rump hurt it would be to fiddle with a fuel cap in the snow which would probably be all over the machine. There are folks who have some pretty big yards down South, I imagine there are some large yards up there in snow country too. Heck, I'm lazy, I wanna ride back. *snicker*
