Hustler Fastrak starting problem.

I've been trying to diagnose my problem for several days, and ran across this video on YouTube which shows EXACTLY what my mower is doing. It was left out in the rain one night about a week ago, but that's happened a couple of times over the past couple of years with no problems. I can hear the spinning sound when I turn on the ignition, but doesn't seem to want to turn over at all. The battery also checks out fine. Any help is appreciated!
