I found this mower to be useless. I couldn't mow more than 1 foot without the blade stopping and I have a really small yard. And unless you have the perfect tools, adjusting the blade is extremely difficult. I guess there is a reason why they don't have this model on stock at the nearest Home Improvement stores. I returned it. The only good thing is that I got a good cardio workout. It is actually lightweight to move on level surfaces, but on the grass (8' X 8') it took me an hour and 1/2 to mow the yard. And now my yard looks really patchy, like allopecia, because I had to use the weed eater to help.
