Reviewers say the Black & Decker MM875 is a great lightweight alternative to bulky gas mowers. Its 12-amp motor starts with the push of a button, and the 19-inch polymer deck is covered for life. The MM875 excels at mulching and includes a bag to collect clippings. On the downside, some owners say it doesn't perform well after a few years of use.
Light-duty. The MM875 is outstanding at mulching, according to hundreds of owners and one comparison test from a professional consumer organization. Another expert says it excels at bagging, though a few owners find the mower doesn't fill the included bag evenly. Overall, reviews say it's best for small lawns with few trees or obstacles to entangle the cord.
The 12-amp motor starts quickly with the touch of a button. Most users say the MM875 gives a clean cut. "The mower is reasonably powerful, but struggles when the lawn is not very dry, or in areas where the lawn is thicker or longer," writes a user at Amazon.com. Though it's stronger than the 6.5-amp LM175, this corded mower is best for light-duty cutting. With an optional chute, owners can choose to discharge grass out the side.
Convenient. The MM875 has a one-touch button to adjust the deck from 1.25 to 3.5 inches. Reviews also say it is easy to push and steer with a 19-inch deck that maneuvers well in tight spaces. One Amazon reviewer says it's "extremely light for an almost one-handed [sic] operation when mowing."
The handle on the MM875 features ergonomic grips, different height settings and folds down for storage. Owners at Amazon and Sears.com say it's efficient; they didn't even notice a change in the monthly electric bill.
Though many owners reviewing the MM875 call it reliable, numerous others contend after a few seasons the MM875 begins to have mechanical problems. For some, the mower only lasts three years. There are quite a few complaints about Black & Decker's customer service, and several reviewers say locating a repair shop authorized to handle warranty repairs is difficult. For two consecutive years, Black & Decker lawn mowers rank below industry average for customer satisfaction, according to J.D. Power and Associates surveys. The MM875 has the same two-year mower, limited lifetime deck warranty as the LM175.
Safety switch quickly stops motor and blades. For safety, Black & Decker uses a switch held in the right hand while mowing; letting go of the switch quickly turns the motor and blades off. We didn't find any expert opinions on the safety features of the MM875, but a few Amazon reviews say this switch is a user-friendly feature.
Extra consideration must be used for any lawn mower with a cord. Most users say they follow a similar pattern to vacuuming and don't feel it's too complicated to keep an eye on the cord.
Loud for electric. Black & Decker estimates that the
MM875 can be as loud as 85 decibels, which according to safety experts warrants
wearing hearing protection like
