The way to adjust the alignment on any Cub Cadet or #series Lo-boy is to adjust the tie rod ends. Back off the jam nut, then spin the tie rod end (part #7 from the diagram above) out or in on the tie rod, then re-tighten the jam nut. However, it is unlikely that you knocked it out of alignment unless you bent something. If you stopped the tractor by hitting the stump, you have likely bent something. My guess is that you have bent either the spindle itself or the arm on the spindle, and it is hitting the axle stop too quickly. In either case, you likely need a new spindle, or you may have to straighten it. Be careful if you try to straighten it, as they tend to break if torqued on too many times. If you clean it off you should be able to see either chipped or wrinkled paint where the bend is.
