  • Fantastic Design Makes Up for the Mediocre Power
Style: 40V Cordless Mower Kit
This is a quality product for the price range. I own several 20 volt BLACK+DECKER cordless yard tools and have been really happy with their performance so I bought this mower hoping the batteries were interchangeable. They are not. The batteries that come with this unit (2) are double the size and 40 volts. They take at least four hours to charge out of the box so make sure that is the first thing you do when you receive the package. Set up was ridiculously easy since the unit is shipped 90% assembled already. The shape is impressive and looks like a sleek RC race car except larger (it is the size of a typical mower). The handle to adjust the cutting height is large and easy to use which is good because you will need to start high and slowly work your way down to your desired cutting height (just like the instructions recommend). The unit is very light weight so it was a breeze to maneuver (My kids will be able to take over this chore much sooner)! One battery was able to handle my entire backyard which has a sizeable lawn. There was one area that has been taken over by Tall Fescue which was several inches high. I had to pass over this area at the highest cut-height setting (7) or the engine would quit. I then tried to lower the height to 4 but that was too dramatic a difference and the engine quit. I was able to make another complete pass at 5 before the battery was depleted. I have no doubt that with two batteries I will have no issues mowing my yard in the future. There is a convenient storage compartment on board for the spare battery which is awesome. The power and performance were honestly about a 3-4 range. I still gave it a 5 however because the design and weight or so great and I was able to push this mower with more ease than the self propelled walk behind gasoline mower I used previously. ... show more

  • Batteries make this nearly useless
Style: 40V Cordless Mower Kit
Needing a new lawn mower at the start of COVID, I didn't want to shop in person, so purchased this. The mower itself is lightweight (not surprising, since it's mostly plastic) and maneuverable. Granted it has been over 2 years since I assembled it, but my recollection is that it was straightforward to put together. Unfortunately, a major problem - and what brings my overall rating of this mower to just 1 star - is that the batteries don't last long enough to do the job. My home sits on a quarter-acre lot with a house, shed, driveway, several trees and a garden. If the grass wasn't overgrown, I could mow the yard in 45 minutes with my old corded mower. The description of this mower stated that just one of the two included batteries would last the amount of time I needed to complete cutting my yard's grass. Unfortunately, this was never the case. The original two batteries combined have never lasted the 45 minutes that were promised for one battery. On top of that, only one charger was included, so only a single "round" of mowing could be done at a time. With a charging time of several hours, I often had to wait until the next day to resume mowing. After a couple months of frustration with the above situation I purchased new batteries and a second charger. When I made the purchase, I stuck with Black & Decker batteries. I verified that the voltage, amps, etc. were the same. The batteries also looked identical in the pictures I could see. Unfortunately, when the batteries arrived they were obviously not right for my mower, as the connectors were wrong. Last year I purchased another replacement battery and charger. This battery was stated to have twice the capacity (amp-hours) as the originals. Unfortunately, it also fails to last anywhere close to the 45 minutes (let alone the 90 minutes one would expect) I need to get the job done. At least I can get in two "rounds" of mowing now. Another frustration is that if the grass is overgrown and thick, the mower stalls quite easily. With the battery situation being what it is, this often happens as I need several days to mow my yard. The method I've adopted when dealing with this is to "pop a wheelie" with the mower: Where there is a small patch like this I will just lower the mower onto the patch. Where there is an extended stretch of such grass I mow over it multiple times in order to get it to the desired height. This can extend the time needed to cut the grass quite a lot. When I was younger it seemed that Black & Decker had a pretty good reputation. Unfortunately, this experience, a few others, and some things I've seen & heard from other sources, leads me to conclude that they no longer deserve that reputation. I certainly won't be buying any more of their battery operated tools in the future. Update: At only three years old the starting mechanism failed. I tried to fix it myself, but found that beyond my skill. With the problems mentioned above, I wasn't willing to put more money into having it repaired and bought a replacement from another manufacturer. ... show more

  • Good buy for the money
Style: 40V Cordless Mower Kit
>-- Summary --< pros + Got my whole yard (about 9000 sq ft, just under 1/4 acre) even after being overgrown + Very quiet, makes about as much noise as a high powered indoor fan + Extremely light, almost felt like a toy when I was using it. + Easily adjustable handlebar, you can get it in the perfect spot so pushing it is effortless + Folds and stores to take up very little space when not in use. cons + A lot of plastic parts, including the wheels, doesn't feel super durable (but should be good as long as not abused) + Required a battery change to get the whole lawn (comes with 2) + Comes with 2 batteries but only one charger (an inconvenience) I bought this after having owned the previous model of this lawn mower for about 5 or 6 years. The previous model had a 36v sealed lead acid battery, and it worked perfectly for those 5 or 6 years. Batteries do wear over time, and since the previous battery was expensive to buy when I needed a replacement, I decided to spend a little more and try this "entry level" cordless lawn mower. I just finished mowing my yard (about 9000 sq ft), which I had let go for about 2 weeks. A little overgrown, but not horribly so. I was able to get the entire yard in one go, although it did require using both batteries (there is a storage slot for a second battery in the mower). It was a very effortless job. The mower itself has handlebars that are easily adjustable so you can get it at the perfect ergonomic height, and it is so light weight (even lighter than my previous cordless mower) that I basically felt like I was going for a walk instead of doing yardwork. All in all, I have to say that for the money, this is an impressively built yard tool, and B&D made the right design decisions to keep it affordable. There are improvements I would like to see, hence only the four out of 5 stars, but these are more annoyances than anything. I feel like this purchase is absolutely worth the value. 1 - It would be nice if it came with 2 chargers, since it uses two batteries. I tend to recharge after use so I don't have to think about it, and with only the one charger I have to charge over 2 nights and remember to switch the batteries. 2 - It would be nice if the storage slot for the second battery was another power source. They could either link them together, or put in a switch to go between one or the other, but it would save me the 30 seconds it took to change the battery (again, ultimately an inconvenience). 3 - It would be nice if B&D sold a multi-battery fast charger (3-4 batteries). The fast chargers they sell still take about 2 hours to charge the battery. A multi-battery fast charger would make it easy to go "all in" on the cordless suite of yard tools (edger \ line trimmer \ hedge trimmer \ chain saw) for one of those extended yard work days. 4 - It would be nice if B&D sold higher amperage batteries. The batteries are 2 amp batteries, a 4 amp battery probably would have gotten the whole yard. There are 3rd party sellers who seller higher amp batteries, I may invest in one eventually. Any of the improvements I had listed I could have overcome by buying another brand of lawnmower, but the brand I know of that has all those improvements is twice as expensive. Again, these are inconveniences, the important thing is that my lawn was mowed in one go, it was pretty effortless, and the noise was so low I could easily hear my headphones while mowing. ... show more
