how do I replace the blades on my John Deere 855 60 inch cut lawn tractor. When I try to remove the blades by loosening the nut, the blade just spins, I have even tried to block the blade fron turning
i block my blades with a piece of 4 x 4 about
1 1/2 ft in length. i wedge it against the deck housing. not real difficult, but tricky until you do it once.
