hey all.

I have a rover mulcher with what I think is a 171cc 4HP on it. I have taken the body apart and now I need to take the old engine off and I want to put a newer second hand one on. I Have gotten to this stage of taking the blade off.

I have taken all the nuts off but it still wont come off and i think it has something to do with that round piece of metal in the middle of the blade.
