BLACK+DECKER CM1640 16-Inch Cordless Mower, 40-volt


Lightweight, easy to maneuver, and no cords (view larger).

Designed for cutting efficiency and the freedom of cordless convenience, the Black & Decker CM1640 16-Inch Cordless Mower is ideal for smaller yards up to 1/8 of an acre. Weighing only 38 pounds, the CM1640 cordless mower is lightweight, compact, and easy to maneuver for great cutting results with minimal effort. It’s powered by Black & Decker’s 40-volt MAX lithium-ion battery system, and the two included batteries combine to give you up to 30 minutes of mowing.

Easy Starting

The CM1640 cordless mower easily starts with just a push of a button, and is a smart, no-mess, no-hassle alternative to gas powered lawn mowers. You’ll save time by eliminating the frustration of pull cords, the hassle of mixing gas and oil, as well as trips to the gas station and engine maintenance.


Handle folds down for convenient storage (view larger).

Cutting Convenience

The CM1640 features a cutting height range of 1 to 3 inches and a handy single lever height adjustment raises or lowers all four wheels simultaneously. When beginning to mow, the motor makes a smooth start and then easily tackles thick grass or uneven cutting terrain.

The 16-inch deck is ideal for smaller yards, and the durable and lightweight cutting deck never rusts, and is easy to clean. The soft fabric of the grass bag allows for easy checking by tapping the bag from the bottom to see if it is full. For convenient storage, the mower’s handles fold down and over the mower so it fits nicely in small spaces in sheds or garages. Carrying handles on the mower make it easy to lift and carry.

    It works very well for an electric powered by batteries that fit in your hand. Set up was easy and took about 15 minutes from unboxing, full assembly, and batteries on the charger. Build quality is decent, mostly very heavy duty plastics with some metal like the handle. The batteries chaged quickly and in about an hour I was out mowing. (It came with two batteries and I already had a charger so the process for me was faster then if I would have had just the one charger).I have the 36v weed whacker and also the 36v blower. My weed trimmer is going on summer…
