Many people who own smaller properties but still take pride in keeping their lawns in pristine conditions would be well-advised to consider this mower as a worthy addition to their tool collection. The 3-in-1 design allows it to convert from a mower to an edger or trimmer. These tools give you the precision to care for your grass that simply cannot be achieved through the use of a standard mower.

Aside from its ability to complete a variety of lawn care tasks, this model boasts several convenient features which allow it to enhance the overall comfort and personalization for users. It was designed with superior control, comfort, and utility in mind. Using this mower to tend to your lawn will lead to results that do not disappoint.

Keep reading our Black Decker MTE912 review to learn about the features and advantages of this tool.


3-in-1 design — This unit is so much more than just a mower; it can convert into an edger and a trimmer in order to achieve finer, more precise results when tending to your lawn. By taking advantage of this, you can take your lawn care to the next level by reaching spots that the average electric mower wouldn’t be able to access.

Gear drive transmission — This transmission allows the mower to overcome tall grass and large masses of weeds rather than getting bogged down. Don’t let the ergonomic design of this mower fool you—there is more to it than meets the eye in the sense that it has the power to slice through heavy vegetation without getting overwhelmed.

6.5-amp motor — Due to the fact that this tool can do the job of three different lawn care units, it was important to fit it with a motor that can cope with high volumes of work and power through jobs without slowing down. At 6.5 amps, this motor will quickly get your lawn under control.

AFS line-feeding system — The AFS system constantly feeds line to the unit as you go about edging and trimming. This saves a lot of time and hassle since it removes the need for any bumping while you work.

Lightweight design — The ergonomic design of the Black & Decker MTE912 allows for continuous use without the common issue of user fatigue. Working with heavier units usually results in the need for rest breaks, tired arms, and even soreness the next day. Thanks to the lightweight construction of this machine, those worries are a thing of the past.

Foot pedal release — A convenient foot pedal release allows users to detach the trimmer/edger unit from the rest of the mower. Thanks to this feature, going from one stage of your yard work to the next one has never been easier.

Detachable mower deck — This feature allows for much more flexibility depending on what works best for you. It provides two height adjustment options that can raise or lower all four wheels.

Corded unit — Since this is a corded unit, there’s no need to worry about when the battery might die or how long you have to wait to recharge it. Furthermore, it doesn’t run on gas or give off any emissions, so it’s better for the air you breathe and the environment at large.

Let's review the advantages of the Black & Decker MTE912.


  • The 3-in-1 design allows users to use a single tool to reap the benefits of owning three different lawn care tools without having the drawbacks of purchasing, storing, and maintaining all three
  • It is fueled completely by electric power, so no fumes or emissions pollute the air during use
  • You can save money since you don’t need gas
  • The corded design allows for continuous use without the issue of limited battery life


  • Intended for properties of 1,200 square feet or less. It is not suited for more extensive jobs or large properties
  • Due to the corded design, its use is limited strictly to areas nears electrical outlets or those which can be reached via an extension cord


All things considered, the Black & Decker MTE912 is a unique and powerful little machine which changes the game for lawn care power tools. Its most notable feature is the 3-in-1 design, and users get a range of benefits by owning a single tool that can serve as a mower, edger, and trimmer. Beyond that, its lightweight construction, technical specifications, and user-friendly design all provide a comfortable and simple user experience in order to make yard work a bit easier for you.

Purchasing a mower, trimmer, and edger all as separate tools versus purchasing a 3-in-1 tool like the Black & Decker MTE912 is much more than just comparing price tags. There are other factors to consider as well.

For one thing, many lawn and garden power tools run on gas, so that’s an additional expense to consider. In comparison, the Black & Decker MTE912 is a corded unit that runs solely on electricity. Not only is this great news for your wallet, but no gas also means no emissions during use. This results in cleaner, fresher air for you during yard work.

Additionally, imagine all of the storage space which is saved by owning one mower-sized machine instead of three separate units. Embrace the spirit of minimalism by maximizing the storage space in your garage to allow for easier access to everything you have there.

Even though this mower has a lightweight design, there are a couple of features which provide it with more power than one might first expect. The 6.5-amp motor provides the raw cutting power that’s needed to go from mowing to edging in a matter of seconds. Since this tool was designed to do it all, it was necessary to equip the Black & Decker MTE912 with a motor that can keep up with the expected output of work.

The gear drive transmission can also push this mower through thick grass and weeds without stopping. Users who wish to tackle thicker grass or inclines with this mower would be pleasantly surprised by how much it can handle. The adjustable mowing deck can also be set to two different heights, and the mower is intended for grass between 1.6 and 2.4 inches.

Once you’re done mowing, you’ll want to take advantage of this machine as an edger/trimmer. The AFS system on the Black & Decker MTE912 allows feed line to be constantly fed as you work so that you can focus less on bumping and more on giving your property the precise fine-tuning that it needs in order to look fantastic.


The Black & Decker MTE912 is intended for use on smaller properties of about 1,200 square feet or less. Despite this, it can still take on thicker lawns and inclines. Since this is a corded model, there’s never any need to charge batteries or be concerned about when they might run out of energy. Black & Decker also has a very similar cordless model for users who prefer to work with a bit more freedom and mobility.

Looking over our Black Decker MTE912 review, we think this 3-in-1 mower would be an ideal choice for an owner of a smaller property who wants to give their lawn more precise, fine-tuned care. The corded design is also a convenient feature for those who have access to a nearby electrical outlet to power the unit during use. It is great if you’re tired of waiting for batteries to charge or find yourself losing spare batteries.
