What can the Black & Decker MM875 Lawn Hog be used for?
Like most corded electric mowers, the MM875 is best suited for smaller lawns up to a quarter acre in size. Since it requires a constant supply of electricity, it must be plugged in at all times. Therefore, if you are considering the purchase of an MM875, you should make sure that you have conveniently placed electrical outlets that you can access from your yard.
This machine is built to handle fairly flat and debris-free yards, so it is ideal for smaller residential lawns.
The fact that it is able to bag, mulch or discharge is appealing to many users since each function can come in handy depending on the situation.
Even though the included bag is not especially large, it is big enough to handle the clippings from smaller yards.
One important feature of this and other electrically-powered mowers is that they run very quietly. If you live in an area with noise restrictions, this is a very valuable aspect of the MM875. Though the spinning blade produces some noise, it is not nearly as loud as a typical gas-powered machine.
Also, the fact that the machine produces no emissions means that it is a valid option for areas with strict emissions regulations. If you live in California, CARB compliance is a crucial concern, but when you operate a mower like the Black and Decker MM875, you need not concern yourself with such compliance issues.
The electric motor
Like most electrically-powered lawn mowers, the Black & Decker MM875 features a 12 amp electric motor.
This size is ideal for lawn mowers since it supplies adequate power for grass cutting in an efficient package. Most users find that the 12 amp motor, while not as powerful as a typical gasoline-powered engine, supplies enough power to cut most grass types.
Power is supplied to the mower via an extension cord which must be plugged in no further than 100 feet from the machine. If you want the maximum range, it is recommended to purchase a heavy-duty 12 gauge extension cord. Using a high-quality cord ensures that the electrical load is handled properly between the outlet and the mower.
Handling and operating the Black and Decker MM875 Lawn Hog
Using the Black & Decker MM875 Lawn Hog mower is very easy. Starting the machine is simple and relatively effortless – all you need to do is plug it in, stand safely behind the unit, engage the starter switch and you are ready to start cutting grass.
Even though you must push the machine, its light weight makes (52 pounds) it easily maneuverable.
The electric motor will produce a minimum of vibration. Also, the handle of this machine is padded for even greater comfort.
The fact that the Black & Decker MM875 is so quiet, easy to start and effortless to operate makes it incredibly simple to use. Beware that the simplicity of operation will be negated if you attempt to use the mower on terrain too rough for it.
However, as long as you operate the machine on relatively flat surfaces and you stay near the electrical outlet, operation of this unit is a breeze.
The Black & Decker MM875 Lawn Hog comes with a single 19 inch blade. The blade is durable and effective for mulching, bagging or side discharge.
Although some users may have reservations about the electric motor’s ability to rotate the blade at adequate speeds, people are generally impressed with the motor’s power and grass cutting strength.
The deck is made from heavy-duty, but light materials and it is guaranteed with a lifetime warranty against defects or workmanship.
The deck’s height is adjusted easily with one simple control. All you need to do to adjust the cutting height is squeeze the deck height adjuster and pull up or down. The height is adjustable within a range from 1.25 to 3.5 inches for maximum versatility.
As indicated above, the MM875 is able to perform three different functions as a mower.
It comes with a bag and mulching insert so you can bag or mulch your grass right out of the box. It is also able to simply discharge the grass clippings with a side discharge chute, which is sold separately.
As long as you are plugged in to an outlet, you will have the power you need to cut your grass and operate this machine’s cutting functions effectively.
Cord management is a major concern for operators of corded electric power equipment. Thankfully, this unit is set up to make cord management easy.
The power cord is plugged in near the unit’s handle so you can always have access to it. Also, there is a hook located near the plug that prevents the cord from becoming unplugged during use.
Since cord management is so important, users will be pleased that Black & Decker has engineered this machine to make the process as easy as possible.
One advantage of purchasing an electrically-powered lawn mower is the fact that very little assembly is required.
Once you remove the MM875 from its box, all you need to do is fold up the handle and tighten it into place. Unlike gas-powered machines, this unit does not require you to fill it with oil or fuel. Simply plug in your extension cord, and you will be ready to go.
The included grass bag requires some initial assembly, but it only takes a moment to complete.
Following are some of the important dimensions of the MM875:
- Cutting width – 19 inches
- Mower length – 36 inches
- Mower height – 17.6 inches
- Mower width – 22.5 inches
- Weight – 52 pounds
One of the major benefits to owning an electrically-powered push mower is the fact that there is very little maintenance required.
Gas-powered mowers require you to change the oil periodically in addition to fueling and they also require tune ups and spark plug changes from time to time. None of this is required for owners of the Black & Decker MM875.
This is not to say that the machine is completely maintenance-free, however. Users must maintain a sharp cutting blade, plus they should clean the underside of the deck regularly to ensure effective use.
The most useful and popular accessory for the MM875 is the optional side discharge chute. The mower comes equipped for bagging and mulching, but you must purchase the side discharge attachment to discharge the grass to the side. The accessory is inexpensive and it is available from your Black & Decker dealer.
You’ll also need a decent outdoor extension cord.

- Ability to bag, mulch or side discharge
- Virtually no maintenance required

This mower is so popular that it has received over 500 reviews on Amazon.com. The average rating is 4.1 out of five stars, which is outstanding.
Of the 502 reviews 240 people gave the MM875 a five star review, with 159 reviewers giving the machine four stars. That means very nearly 80% of reviewers give the MM875 4 or more stars.
The positive customer reviews cite the machine’s power and ease of use as major benefits. Reviewers love the ease with which the deck is adjusted, and they are generally pleased with the mower’s cutting ability. Users are also very pleased with the machine’s quiet operation and need for very little maintenance.
Negative reviews seem to indicate that many people are purchasing this machine with higher expectations than it deserves. Some people have noted a lack of power, but they may be more accustomed to gas-powered mowers and some are not impressed with the polymer deck. Other reviewers have expressed dissatisfaction with the bag’s inability to store clippings without spillage.
Here is what two reviewers have to say.
First a 5 star reviewer:
“Just as other reviewers have stated it arrived in a big box on my front porch. Assembling the handle and attaching the bagger was a snap. It IS a two-prong input into the handle of the Lawn Hog – I already had that type of cord. I plugged it in, pulled up the orange handle up and WHAMO! It roared to power! In my opinion, this mower is comparable to a 6.5HP gas mower – others may disagree but I will tell you, this thing is POWERFUL. It cuts the grass with the cleanest cut out of any mower I have ever owned and does no damage to the lawn sprouts (as long as you do not set the height adjustment to scalp your lawn). The height adjustment is fingertip easy.
TIP#1: To assure the bag fills evenly
With the bag empty – cut for about 2-3 minutes, stop the mower, take off the bag, shake the accumulated contents to the rear of the bag and put the bag back on the Lawn Hog. Now you should be able to cut until the bagger reaches capacity and it will fill evenly.” Read more …
And this, from a 3 star reviewer:
This product is not perfect. It is largely plastic, and prone to breakage if you use it as though it is of the old, all-metal construction. In fact, between the time we took delivery on our second unit and my dropping the first at the dump, we had to cannibalize a part from the prior unit. That said, we prefer an electric model, and when used judiciously it will plow through and handle long, thick grass and mulch up leaves, to boot. Just be sure not to run it over hard objects, which one shouldn’t do in any case, but the plastic construction really comes clear when you might do so. Also the electic motor can burn out if you try running it mercilessly in damp grass. Read more …
