I bought the Black & Decker 19-inch Lawnhog Electric Mower used off of Craigslist. It was already a few years old, but it worked perfectly. I had to buy my own power cord, as the original owner had lost the one it came with, but it was easy to look up online what kind of cord it needed. This was an extremely easy lawn mower to use. I have even used it with a newborn in a sling in front of me, fast asleep, and did not have any problems at all, safety or otherwise. It was extremely easy to push, even in slightly wet grass. It worked well in the backyard, even when weeds were over a foot tall before we were able to put grass in. The only concern I had was that I might accidentally run over the power cord and cut it. I never had any problems with power, which I was concerned about since before this I had always used lawn mower that ran on gas. I actually prefer this lawn mower to other gas ones that I have used. I really like that I do not have to worry about running out of gas.
