Well, it turned out to be the damn battery. I charged it all day and it started. I was able to cut the grass but when I shut it down and tried to restart it, it barely turned like it was dying so I took it to O'Reilly Auto Parts to get it tested. Sure enough, it's a bad battery. This battery is barely 13 months old. What a piece of crap! O'Reilly only warranties them for 3 months.
