Was loading mower into van using ramps was raining and ramps were wet mower started slipping and tipping.
I shut off mower and repositioned wheels on ramp and loaded mower by hand pushing into van.
Unloaded mower by hand also.
Now mower will not start no click not anything. Checked fuse it is good.

Sure is fun riding one of those to the ground,If your mower turned upside down you may have oil in the top of the cylinder and its locking the engine up
If it doesn't make any sound when you turn the key then I would check if the seat or brake/clutch lever is bent. Ether one will keep the safety switches from making contact . If those are good ,if you have a test light ck battery and work your way down to the starter while turning the key to start when you loose your 12v you found your bad connection
