Any lawn mower or lawn tractor will rust if it is stored outside or in a humid environment. The paint on lawn tractors is not nearly as good as automotive grade paint, and simply doesn't stand up to the elements as well over time. Once you've got a rust problem, I don't think there's a whole lot to do other then try to limit further degradation. Rusty equipment, just like cars with rust problems, isn't worth much, but if you don't plan to sell it, you can probably get plenty more hours out of it if the engine and tranny are still good and you keep it away from rain.
