My Super H sits unstarted for 6 - 7 months every winter/spring. Here's what I do:
Shut off the fuel at the sediment bulb and run the engine until it quits. Then remove, clean and replace the glass bowl.
Disconnect the battery ground cable, or remove the battery.
Either fill the fuel tank full, or drain it completely. Don't leave it with a couple inches of gas in the bottom - if the gas contains ethanol it'll attract water, go stale and may cause rust inside the tank.
Finally if the tractor is stored outside place a large can or bucket over the exhaust and tie it down to keep rain out. I also like to cover the seat.
