The Black & Decker CMM1200 is part of the lawn mower & tractor
test program at Consumer Reports. In our lab tests, push mower
models like the CMM1200 are rated on multiple criteria, such as those listed below.
Reflects a combination of evenness, which is how close the mowers came to even, carpet-like mowing, and how completely the mower distributed its clippings over the lawn's surface.
Denotes a combination of evenness, which is how close the mowers came to even, carpet-like mowing, and how much clippings the bag held before it filled or the chute clogged.
A combination of evenness, which is how close the mowers came to even, carpet-like mowing, and how evenly clippings were dispersed from the side-discharge chute.
About This Brand
Black & Decker is the leading manufacturer and marketer of corded electric and electric rechargeable mowers. Black & Decker mowers are available in only sub-20-inch cutting widths and in mulching and rear-bag configurations. Black & Decker mowers are widely available online and through Home Depot, Lowe's, and Wal-Mart.
Can bag Indicates whether the mower can cut in the bagging mode. In this mode, the clippings are gathered in a removable catcher. Lawns tend to have the best appearance after cutting in this mode because the mower essentially vacuums the lawn clean and leaves very little debris behind. This advantage is offset by the need to periodically empty the catcher and dispose of the grass clippings.
Can mulch Indicates whether the mower can cut in the mulching mode. In this mode, the discharge port is closed off, and the mower re-cuts clippings until they're small enough to settle and decompose in the lawn. Cutting in this mode reduces the need to fertilize the lawn because some of the nutrients from the clippings are returned to the soil. It is also more convenient because there is no need to empty a catcher or dispose of any clippings. Certain conditions are required for successful mulching, and if these conditions are not met, many visible clippings can be left behind on the lawn. For successful mulching, one should avoid cutting more than one third of the grass's length, cutting wet grass, or cutting at too fast a pace.
Can side discharge Indicates whether the mower can cut in the side-discharge mode. In this mode, the mower simply discharges the clippings off to the side of the mower. Depending on the length of the grass cut, this method tends to leave many visible clippings behind. This mode is preferable when cutting tall grass because the mower is less likely to clog, since the clippings are quickly removed from the deck.

Deck size (in.) Most models have a deck size, or cutting swath, of 20 to 22 inches. There is no significant advantage from one size to another. A larger deck can cut more grass in a single pass, but in this size range the difference is negligible.
Deck size (in.)
Engine size For gas-powered mowers, engine size in cubic centimeters (cc) provides a rough indication of the engine's power; electric models are rated in volts (for cordless) or amperes (corded). A larger number for either a gas or electric model, however, does not necessarily result in better cutting performance.
I have had this mower for 6 years now. Initially I found the battery losing power after a year. I replaced the battery and kept the mower in my shop which is kept at 70 F after that. I am still on that second battery with no loss of performance. I mow about 6000 sq ft twice per week in peak growing times, less as summer progresses. Besure to keep the blade sharp and well balanced. I had to replace the safety switch twice, both times under warranty. This mower is 24 volt. I will probably replace with the 36 volt sometime in the future. I will never go back to gas. Theses mowers are smooth and quiet and very reliable.

Love the instant start. I hated yanking on gas mower strings. I love the easy height adjustment. No struggles there. I'm a fit 60+ woman with about a1/3 acre yard.<br />This unit started to constantly overheat right after the warranty ran out. It runs for about 3 minutes at a time! Very, very frustrating. Longer grass is nearly an instant stall even at the high setting.<br />Probably going back to gas even though I think electric is more Eco-friendly.

No gas, no repair bills, reliable
Easy to Push & Steer
I've had this mower over three years now and have always been pleased. I have 3/4 acre but the centipede grass grows slowly, so I can alternate front and back yards each week. The mower has a hard time with thick, wet grass, so this mower will work best for you if your lawn is not too lush. I have not noticed any capacity fade in the battery over the last three years. I can't understand why other reviewers say this mower is heavy - it is far lighter than ANY gas mower I have ever used, and that makes pushing the mower much less work! Another benefit that has been overlooked: if you have a lawn that puts up a lot of dust or debris (e.g. dry pine needle bits), this mower will not suffer from contaminated air filter, air intake, or carburetor system. I have saved more than the cost of the mower in savings from not having to take it in to the shop for cleaning and repairing the fuel system. If they would add some battery capacity, I'd give it five stars.
