Riding Lawnmower Freak Accident [Video]

I recently heard some good news from the city of Flint. There are two vacant lots behind my house that I have been asking about for over a year and last week they told me I can buy them if I want for SUPER CHEAP!! My immediate concern was with the extra land being added to my house how will I be able to cut such a large lot?Immediately I thought about a riding lawnmower (I just have to figure out how can I afford it). The only thing is I'm not sure how to use it.

I'm sure it's easy to use but I don't want to be in some sort of accident and look like a fool, something like this guy.
