The batter would be the weak spot. Lawn mower battery plates are quite thin and would have a good chance of warping and shorting out internally. As long as you didn't smoke any wiring you should be safe. The starter would turn backwards while hooked up incorrectly, but the bendix would not engage and thus wouldn't do any damage.
