Rated 5 out of 5 by I Love This Mower! I don't usually take the time to write a review on anything. But after owning this nice little mower for a month, I am really impressed with it. I have not once started this mower with the pull start, why you ask, because I don't have to. One little turn of the key and it fires right up every time. The motor is powerful while being very quite at the same time. I love the adjustable speed on the self propel drive. The only thing I would add to this mower is the deck wash port. I almost purchased the Honda Electric start self propelled mower for $499 but I passed on it and got the Lawn Boy and I an glad I did. I hope this review might help someone else who is "on the fence" like I was. July 18, 2014
Rated 3 out of 5 by Not bad for the price The electric start is great for those of us with bad backs. I have never had a mower that starts so easily. The variable speed, self propelled feature is a bit awkward to use but will likely be ok once I become more accustomed to it. Without the bag, the mower works quite well, however, the bag is a disappointment. The bag is easy to empty but is very small. If you usually use a bag, you will not like how often you need to empty it. The bag does not work with wet grass. May 4, 2014
Rated 5 out of 5 by Works great! It was easy to put together. The self propel works great even in thick leaves. The blades mulch leaves really fine. I love the electric start. I'm a 59 year old female and this lawn mower is great. April 22, 2014
Rated 5 out of 5 by Always starts first try! Great mower! Easy to clean out after mowing too. I have a bad back and cannot do repetitive motion without pain. The electric start is a good feature and always works. battery charge lasts a long time too. April 15, 2014
Rated 5 out of 5 by Good Buy! Mower arrived slightly damaged, battery box lid and battery were found in shipping carton. Looks like carton was flipped over during handling and battery fell out of its plastic box and snapped lid off. Called Home Depot, they wanted me to return unit, told them damage did not affect functionality, asked for a replacement battery box on a Friday, it arrived following Tuesday! Plenty of power, much more so than 2 cycle Lawn Boy it replaced. Recoil start very easy. Battery came with nearly full charge even though they recommend charging battery 24 hours before use. Just remember, lawn mower DOES NOT charge battery! Battery must be charged with included AC power cube charger that plugs into wiring harness or remove battery and use external gel cell battery charger. Mfg. recommends recharge approximately every 25 starts. If you like to walk fast, this is a great unit! Self propel speed might be a little fast for some people. Definitely recommend this mower!
