It is gas, so it is a power mower. A hand mower does not have an engine.

"There's a difference between interest and commitment. When you're interested in doing something, you do it only when circumstance permit. When you're committed to something, you accept no excuses, only results." ~ Art Turock

I am with Niteman on this. A hand mower is the old school, rolling blade mower not powered by gas or electricity. A power mower may be self propelled or not and of course, self propelled it easier and, in my opinion, worth it. I hate mowing, so anything I can have to make the process a little easier is worth it.
