Item Specifics

The Black & Decker Cordless Electric Lawn Mower has a highly efficient and sleek design.  It runs on 36- volt batteries to provide you with both power and convenience.  A cordless lawn mower is nice because you don’t have to contend with a cord like you would with an electric lawn mower.  You also don’t have the high maintenance nor high sound volume of a gas powered lawn mower.  This lawn mower was created to help you keep up your lawn without the hassle, expense and emissions of gas-powered models.

With this lawn mower you get an instant start that includes the bagging.  A 1- touch height adjustment makes folding this lawn mower up and down easy.  It folds up nicely for compact storage in your garage or shed.  The included charger is Energy Star rated.  One of the coolest things that I liked about this lawn mower is that you can insert a conversion plug to convert this machine from a mower to a mulcher.

The wheel height can be adjusted with the pull of a lever.  The battery is made to cut up to a typical 1/3 acre of lawn on one single charge.  Just start it up with a key and a quick pull of a handle.  Once it’s started, enjoy quiet operation without worry of disturbing wildlife nor your neighbors.

Bag Included but Not Necessarily Needed

A bag is included with the purchase of this Black & Decker Cordless Electric Lawn Mower.  Though it comes with the lawn mower, it seemed like most of the customers started off with the bag, but then discontinued using it.  Because this lawn mower mulches up the grass so tiny and evenly distributes it, most people didn’t even feel it was necessary to use it.

You Will Need to Carry a Charged Battery or Wait for Battery to Charge

One drawback of battery lawn mowers is that the charger can only carry a charge so long.  It seemed like the norm was about 1/3 an acre that this lawn mower would cut and then you need to put in a charged up battery.  

Comes with Plastic Key for Safety

Because this lawn mower is so very easy to start, it comes with a plastic key for keeping kids from starting it up.  The key was as controversial topic.  While some didn’t mind it, others thought it was unnecessary.  One customer was discouraged because he was all set to start to use this lawn mower, but the key was not included.  The company promptly sent him the key.  He was very satisfied with the service but wished it didn’t need the key.

Easy to Assemble

Based on feedback from customers, the Black & Decker Cordless Electric Lawn Mower is easy to assemble.  The main thing that you will have to do is simply attach the handle and put the trimming catcher bag together.  I did not find customers complaining about having a hard time assembling this lawn mower.

Low Noise

One of the best features about the Black & Decker Cordless Electric Lawn Mower is that the noise output is very low.  This is a real plus if you have close neighbors.  You won’t have to worry about disturbing sleeping babies nor mowing too late into the evening.

Easy to Start

Another great feature of this lawn mower is that it is easy to start.  Some of the customers who bought this lawn mower, specifically purchased it because they were tired of struggling and wasting time trying to get gas mowers to start.  This starts with the simple key and button.

Black & Decker Cordless Electric Lawn Mower Conclusion

The Black & Decker Cordless Electric Lawn Mower has some great features.  It produces low noise in comparison to a gas mower.  It is easy to assemble and also easy to start.  You will need a plastic key to get it to start, which some people found was a nuisance.  But this feature is there to prevent kids from starting it up too easily.  A bag is included for grass clippings though it’s not necessarily needed. People who bought and used this lawn mower found that because it chopped up the grass so well and distributed it so evenly, that the bag was not necessary.

Common Questions

Here are some top questions that I found for people considering buying a Black & Decker Cordless Electric Lawn Mower.

  • chevron-circle-right How do you change the height of wheels?  There is one lever which changes the level simultaneously for all 4 wheels. 
  • chevron-circle-right How big is the bag? What is the size in bushels?  It measures 22″ long and 12 ” wide and 10″ on the side. 
  • chevron-circle-right How do you store cordless mowers in the winter?  From the Black and Decker Website:  When storing the mower in an environment that will be consistently below 40 degrees Fahrenheit (but not below -40 degrees F), the battery should be fully charged and disconnected from the charger until the next mowing season. The battery can remain in the cold temperature, but will have to be charged before first usage in the next season. Alternatively, the battery can be brought inside to a warm environment with the battery connected to an active charger.
