Bought new in Apr 2011. Started it yesterday afternoon, drove it out of the garage into driveway, shut it off, installed new mulching cover, got back on, and then nothing. headlights work, no noise, nothing turns over. Full of gas, been using it fine all spring/summer. Checked the 20 amp fuse, all good there. I know it just has to be something very simple. Please advise. Dealer appointment for later next week, like to get it going to cut the yard, about an acre and don't want to do it with the push mower. yea I know, call me a wimp. Thanks, Phred sends
