I was reading the talk on changing blades or replacing them with sharp ones. Today was one of those days for me. I did the Toro WB and it wasn't bad but still a pain. Putting it on ramps and then blocking so it wouldn't fall. Then bustin the nuts and replacing the blades. I love the Walker. This is the 52" deck with factory doubles. This thing sounds like a helicopter. Piece of cake to change the blades. It takes 5 minutes. Well thats all the bragging. I'm not as fast in the straightaways but I still get the job done with $$$ in my pocket.
