I wax my tractor and vehicles and even my brush hog with canaba wax. If you like to work really hard, use Turtle Wax. Good waxes just wipe off after they dry. Actually, Turtle Wax does have a brand that is a new type. Just don't use the old-fashioned kind that almost requires sand paper to get off when dry.
I only wash my tractor every so often, but it comes out nice and shiney when I do. Most times, I just use the air hose and blow stuff off it.
