I got sick of struggling to start my push mower that only gets used every few months, so I decided to start it with a cordless drill (you can use an electric drill if you don't have a cordless one).
I didn't bother showing how to get the pull start mechanism off as it will vary from mower to mower.

Do this at your own risk.
