Changing the Mower Blades

42” blades have needed changing for a while - last week - it hit something and bent the blade. - so I had no choice but to change them.

How do you keep the blade from turning while trying to loosen nut?

These loosened right up. However - I have had to use a block of wood before to wedge them.
