Rated 5 out of 5 by from Great features!` It's very heavy. Really like this lawnmower, but it's a bit heavy and large for a smaller yard. Would be perfect for a larger yard. Runs well, starts easily, charges fast. Batteries are heavy.

Rated 5 out of 5 by from Easy, powerful mow I waited to review this lawnmower to be sure my perceptions are correct. After three mows through some fairly heavy growth I can report the self-propelled variable speed function is perfect. The mower actually picks up blade speed and power when it encounters heavier grass growth. I'm ready to turn this new mower over to my wife for her use (we have two properties to maintain). The ease of adjustment, low effort required for maneuvering, ample power and safety features, all make me say: If you can use an vacuum cleaner, you can enjoy using this mower. It replaces a twenty-year-old mulching self-propelled Honda that I love, but which would have been more challenging for her to operate. Plus the old Honda was stalling out even with a new mulching/bagging blade in heavy grass growth. Electric: No such power problem. As easy as vacuuming! My package included the bagger (I used it once, easy and seems durable) and the side-discharge chute (not used yet, but it fits on the mower fine).

Rated 5 out of 5 by from Works like a champ I bought this mower in the middle of May and have used it three times. It has worked flawlessly. I have a corner lot so it takes one full battery to do the front and part of the back. Exactly what I was expecting. Then fold it up and it takes up almost no room in the garage. I would recommend this product to anyone.

Rated 4 out of 5 by from Great battery powered mower Very happy with the mower. It's powerful and easy to handle. The self propelled function is legit. I'm a fast walker, but when I may the handle all the way the mower is pulling me along. It has been a few weeks since I cut my grass and it was able to handle the length. The only downside I found is that it doesn't pick up the cuttings of the sidewalk like my old gas mower; it just doesn't have that kind of power. I mowed my lawn on one battery... It was down to one bar.

Rated 2 out of 5 by from I want to like it. I ordered my first one from Home Depot. Shipping was quick. After the first use, I really liked the mower. It cut well and was easy to use. All was well for the second cut as well until the blades stopped running. The light and self propel features were fine, but the blades wouldn’t run. I checked that there was nothing blocking the blades. I also tried the other battery to see if that was the problem, it wasn’t. I couldn’t resolve the issue myself, so I went to Home Depot and exchanged it for a new mower. I got that one home, charged a battery up, and went to finish my lawn only to learn that the new one has blades that hit the mower deck. Also, I’m not sure if it’s a defect or not, but a front wheel bracket is bowed out making the tire not roll true. I don’t recall it being this way on the first mower, but don’t know for sure. I want to like this mower, but it’s hard to.

Rated 5 out of 5 by from Very impressed! Better POWER than gas!!! The new mower works fantastic! I was a little skeptical, and thought for sure it would be less powerful than our gas powered mower. But, this thing works perfectly! Definitely much better and quieter than gas. I was easily able to mow the entire lawn with plenty of battery life left. It uses two 40v batteries and there's a “key“ that you use to switch between batteries. We have a very tough broadleaf grass called St. Augustine, and it is tough to get through with anything less than a 7hp gas mower. So, yes every power tool we now use is either a 18v or 40v Ryobi.
