I was mowing the back lawn and i ran up over a large log. I heard some weird noises under the deck. the mower didnt die, so I cut it off. I pushed it off the log and started it back up, everything ran fine, cut fine. It sounded like the blades stopped spinning, but perhaps the belts kept trying to move. Is there anything I should check / worry about? I just bought the John Deere LA105 two days ago heh.
