Thanks everyone, my original plan was to just unhook the loader at the rear axles and roll the back away. I have plenty of 3/4 plywood sheets. I also have some 2'x2' concrete pads about 3" thick, was thinking of putting the floor jack on a few of these instead of on plywood. Based on all your replies it seems like it will work. I sure appreciate the tips.
Should I drain the rear tires or does it matter?
