If you are looking for one yard tool to take care of a few different jobs in your lawn, this might be it. The Black & Decker MTE912 is three tools in one, a trimmer, edger, and a mower. The trimmer/edger fits in to a four wheeled mower base quickly when you are ready to mow. When it is time to trim around the house, fence line, trees, or other objects, simply press the foot peddle on the mower base to disconnect the trimmer. Having three tools at hand will allow you to finish the yard work in short order, and get back to the important things in life.

The gear driven transmission allows the trimmer/mower to keep a constant speed when you come to tough sections of lawn. The Auto Feed System will insure that the trimmer line is always there when you need to cut through the grass or weeds. You will not need to bother with bumping to feed the line out as with other string trimmers.

No more tired and sore arms or shoulders after doing yard work. The light weight, just over 13 pounds, and ergonomic design go a long ways towards reducing your discomfort at mowing and trimming. To further increase your comfort, the handle can be adjusted to various heights, and positions. Making it great for people of all heights to use safely.

The mower deck can be set at either 1.6 or 2.4 inches, giving you the best cut for your grass type. With a narrow 12 inch cutting path, this trimmer/mower is great for small yards and areas of larger lawns that might not be easily reached with a larger mower, like steep embankments, or under low hanging trees and shrubs. Black & Decker recommends this mower for use on a lawn that is about 1200 square feet.

This little yard tool has a lot of nice features packed in to it that are going to make yard work much easier. With three tools in one, you will regain some of your lost time.

Customer Opinionfor the Black & Decker MTE912 12-Inch Electric 3-in-1 Trimmer, Edger, and Mower

At the time I completed my review, 868 owners had made their own reviews on Amazon. Out of those, 61% rated it 5 stars. The mower is currently getting an average review of 4.2 stars out of 5. It is clear this is a well liked popular trimmer, edger, and mower.

In general, customers are happy with this little tool. If it is used in a small lawn it works great for what it is. Other owners commented how simple it was to setup out of the box. It is just a matter of snapping on the guard and a screw for the handle. One owner described it as a “…weed whacker on roller skates…”, but it does what it is supposed to do, and it is capable of cutting through tough crab grass.

Even with the great reviews, this mower does have a few draw backs, according to some owners. The biggest complaint is the quality of the mowing job. While it works well as a trimmer and edger, they feel it does not do that great as a mower. The grass is not cut evenly, and because of the light weight, narrow cutting path, unevenness in the lawn shows up in the grass. Some owners that choose the cordless version do not think the battery last long enough to complete the job, it seems the battery lasts from 15 to 40 minutes. I guess this is going to depend on how tough of grass you are cutting.

The majority of owners do agree that it is a well built piece of equipment, even if it looks like something made for kids. A few comments mentioned how nice it was not to be covered in grass from the larger mowers, and how quiet it was. If you need to mow late at night, or early in the morning you are not going to disturb your neighbors.

Final thoughts
