Bought a Plugr Hydro last week. At first I thought "what have I done?", as it wore me out on 2 smallish lawns I did. Then today, I did my own yard and let the machine do the work, and worry less with the Hydro which I finally figured out would forward without me having to do it. I simply nudge it when going up a slight grade or transporting from a to b. Now that I have a couple of hours of experience under my belt, I am quite pleased with the unit. Cant wait to make more $$$ this week.
