Black & Decker CM2040 40V 20” Electric Lawn Mower

Cut Down on Yard Work Time with EdgeMax

The mower’s EdgeMax design puts the blade in line with the wheels, so every blade of grass you roll over gets snipped. No more edging around flower beds or pavers when you’re done with mowing.

No More Hassle with Oil, Gasoline, or Tangled Cords

The two electric batteries that come with this lawn mower eliminate the need to keep stores of messy oil or gasoline on hand for refills, which also means no more last-minute trips to the gas station when that supply runs low.

Backup Battery Doubles Run Time

With one battery always in reserve, the mower’s can run twice as long. When not in use, the extra battery stores convenient in a compartment on top of the mower, so you won’t have to spend time hunting it down in your garage or shed. The batteries also double as backups for other Black & Decker lawn tools.

About Black & Decker

S. Duncan Black and Alonzo G. Decker started their small shop in Baltimore in 1910—but it wasn’t until 1916, when they sought to patent their version of the electric drill with a trigger switch and pistol grip, that the company really took off. The original model of that signature product, which was much more portable than its contemporaries, is displayed at the Smithsonian in Washington, DC. Within a few years of their invention, the pair had started to sell products in Canada, and by 1930, they were established in Australia and continuing to spread throughout the world. The tools’ reach eventually even extended into space: a Black & Decker tool was part of a drill that was used to take samples of the moon in three of the Apollo missions. Handymen all over the world still rely on the company for power tools and almost anything involving home improvement, from painting and plumbing to hedge trimming and storage.

Only cuts grass on the HIGHEST settings (7) - motor stops when the height is set for anything below 7.
