Mower Won't Restart After Hitting a Stump

I have a Murry Select 17.5 HP 42 inch cut mower. I hit a stump and the mower stopped right away, my husband changed the blades yesterday, charged the battery last night and went to start it today and nothing. It doesn't even try to start.
The kill switch from what we understand had been disconnected by the person we got it from, but if you touch the two wires together it causes a short that will turn the mower off. Please help.

That piece of metal is called a keyway and you can get them at your local hardware store. It is best to bring the old one with you because they come in all different sizes.

There a rectangular shaped piece of metal down where the blades attach that has been sheared off more than likely. Don't remember what they are called but the ex was always shearing them off. They are a safety measure. You can replace them yourselves if you can locate them.
