Ever since I started owning tractors (50+ years) I kept them under a tarp, then when money allowed under a roof they went. Mine are in a building all of their own now, tight fit but they both go in, all implements, with gear boxes, are in a lean to and things like the back blade, disc and box blade are out in the weather. Like every other person with a out buildings I do wish they were bigger so everything could be under cover.
