Query: What a disappointment....

I bought this mower because I thought it was a waste to hire a gardener to mow my tiny San Francisco lawn (it's maybe 15'x20'). It was easy to assemble (though one of the bolts fell out because I hadn't tightened it enough--doing it by hand is not tight enough). The first time I used it, I thought I was going to throw out my back, but I attributed it to the fact that the grass had grown pretty tall (high enough to use a line trimmer). But I just tried using it after hiring a professional to mow it a week or two ago, and it still was backbreaking work. I consider myself a strong person (220 pounds), but I could barely get the thing to budge. Maybe it works if you mow every few days and don't let the grass get too tall. But as for me, I'll probably never use it again.Anyone want a cheap hand reel mower???
