If you're too lazy to do it, guess you don't care what the tractor looks like. I do most of this naked. Makes it fun to do. Of course, it'd be ever better if the wife joined in.
On topic: I was too anxious to use my tractor when they delivered it. Now I don't know if I will ever get it "that clean" again. I am really more concerned about corrosion control than wax at this point. Although I suppose wax could inhibit rust too. When/If I do wax I do not think I would wax all the implement angles. After all it is a tractor not a collector sports car. Just my opinion.
