We chose this mower, because it is an environmentally friendly option. With the price of gas being what it is these days, it makes lawn care a lot cheaper, too. And, I love that I don't have to wear ear plugs to mow the lawn. No motor = no noise. Another plus - if I ever decide to mow the lawn early in the morning, I won't wake the neighbors. What I don't like about this mower is that, even with the blades set as low as they will go, it doesn't cut as close as I would like it to. It's not much harder to push than a motorized push mower, but it's not as effective; stubborn areas need to be gone over more than once. We've only had it since last summer, so we haven't had to sharpen the blades yet (I don't know how much that will cost, but I'm sure it's still cheaper than it would be to put gas in it every week). When we bought this, the guy at Home Depot was telling us that he used to have one, and he had to sharpen the blades only every couple of years. (If I'm remembering correctly). Yesterday, one of the screws that holds the middle bar fell out. I didn't notice it, and the nut had fallen off of the other one. (There are two screws that hold the bar, in the middle, together). So, I had to go to the hardware store for replacements. Not expensive at all, but I guess I'll have to get in the habit of checking the screws before using the mower. For me, the pros outweigh the cons for this mower.
