    So this is my first year owning a Z and I am about to winterize it in the next couple of days. I have 200 hours on it so it is still pretty new. I am going to put stabil in the gas tank and fog the engine but to my main question, is there anything I need to do to the hydro's for winter? Anything else I'm missing besides the stabil, fogging, cleaning and greasing for winter for the Z?

    Also, I have a sthil FS110 4-Mix and I have used it for one season (approx. 25-50 hours). I was wondering if I need to get the valves adjusted or anything special for winterizing (lost the manual) besides fogging and stabil in the tank?

    Toro/Exmark's should have Mobil 1 in the hydro's. Change fluid and filter at recommended intervals (500 hours I think). Nothing else needs to be done to the hydro's.

    just me, but I would change the fluid at the start of the season, instead of the end.

    I think that you can do both maintenanc at the beginning or the end, but I feel that the end would be better. Because then you might find problems that you then would have 3 to 4 months to solve before the start of the season, instead of finding out the problems at the beginning of the season
