I mowed for the last time this year last Saturday. Not that the grass really needed it, but going trough a pile of dry, dead leaves cleans up a mower deck really good.
Now that this is done with, I changed the oil of my snow blower. It's a late 2000s Craftsman 31" with a 11HP Tecumseh engine. I bought it 3 years ago. The auger belt was replaced last year and it now has fresh oil and started on 2nd pull. When used regularly in the winter, it always starts on 1st pull. It can also be plugged to a wall outlet to use the electric starter, but I used it only once to check if it still worked, it did.
I do use E0 fuel (around here only premium fuel at a few stations offer it) with some MMO for light cleaning/stabilizing properties. I do nothing special when storing it for the summer. I don't top off nor drain the fuel or use any stabilizer other than what MMO includes, nor do I fog the carb. Right before the first use, I'll top off the fuel, so old fuel will be mixed with fresh one. I'm ready for snow, despite not really liking it.
