When brake is taken off, motor stops

I have a simplicity 24 HP Zero turn. Last week I turned it over and most of it got wet. I let it sit and dry out and that evening it started fine except for a little blue smoke and used it several times the next day. 5 days later, I started it and it ran fine. When I took the brake off to move it, it stopped. I tried it several times and the same thing happens.
