I just hang it up and charge the batteries every couple of months
another added benefit lol.
I would keep the tank full, fuel stabilizer, pull the plug and spray de-fogger in there, put the plug back and pull the cord a few times and hang it up till next winter. if you drain all the fuel thats when you have problems of everything gumming up. once a year put a spurt 1/2 ounce of sea foam in your tank start of the season
