Has anyone "lifted" a tractor with a 633a trans? I'm looking to lift the rear of my sears enough to make it level with 25x10x12 on the front and 27x12x12 on the rear. I don't imagine it would be overly difficult, but I would just like to see ideas of what you guys have done. (btw, I have access to a welder and grinder, so bolt on's aren't needed but appreciated all the same.)
