Black & Decker CM2040 40V Full Review

The Black & Decker CM2040 40V has the power and the runtime that you need for even difficult midsize jobs. This is a great mower for mowing about a quarter of an acre yard. This mower features mulching, bagging, as well as side discharge.

It utilizes EDGEMAX so that it can come right up to the edge of flowerbeds and other landscaping to reduce the need for weed whacking after mowing. This convenient feature is not only great for working around objects; it also allows a clean line between grass and mulch areas, or at the edge of concrete paths or driveways. If you have lots of landscaping, especially hardscaping, to work around, this mower may be just what you need.

This cordless battery-powered electric mower has variable speeds. A higher speed powers through tough grass and a lower speed conserves battery. AutoSense Technology decides how thick your grass is and adjusts the power needed accordingly.

This enables you to get the best runtime from your mower without compromising on power when you need it. It also means that you may be able to mow the entire lawn in one sitting at one time but be unable to finish without waiting to charge at another time. Since the charge time is so long, make sure you can get your entire lawn mowed, even when overgrown, on one charge before deciding on this mower.

Two 40 volt Max lithium ion batteries come with this mower but only one is used to power it at any given time. When not in use, the extra battery can be stored in a convenient compartment on top of the mower. This battery can be used with any of the 40 volt Max Black and Decker lawn and garden tools.

This mower comes with a 15 gallon nylon bag that lets you easily check the fill level. The height can be adjusted with six different settings that cut between one and a half inch to 4 inches.
