When you order your blades, the items shows a 38 inch blade but the price is for just one blade. Had to order another blade but all went well on the repair. Replaced blades with a wrench and a good strong hand. Used a screw driver to slip the old switch out and replace with the new one.

After installing all the safety switches and still nothing, I noticed that the voltage meter wasn\'t moving when I turned the key so I reached my hand back to wiggle the wires and it cranked right up. I guess it had grounded the mower.

I had to do some testing to determine which switch was bad. Turned out to be the blade switch. Extra time was for testing and the fact that you have to remove the battery and its tray to get at the brake/clutch switch to test it. It works now. Yay
