I have a John Deere 102 riding mower. I got into some tall wet grass and the lawn mower stopped to due to grass getting caught up under the blades. I pulled out and took a less wide path. The mower started to do the same. I pulled out, stopped the blades, then I heard a loud pop/crack from engine. The engine will not start now. WHen I turn the engine over all I get is a whining sound.
