Keep the Yard Nice with an Electric Weed Eater

For several decades now, weed eaters, also known as weed or grass trimmers, have been a staple in the yard maintenance industry.  These machines, which come in a variety of sizes, models and styles, can serve many purposes around your yard, such as keeping weeds at bay and putting a nice straight edge on your lawn.

There are essentially three general categories of weed trimmers from which you can choose:  gas trimmers, battery-powered weed eaters, and electric weed trimmers, which rely on a cord that is plugged into a standard wall outlet.

In the following article we will review several products in this latter category – electric weed trimmers – and explain the pros and cons associated with each of the products we’ve reviewed.  We have also included a “Weed Eater Buyer’s Guide” near the end of the article, in which we point out the various factors and features you should look for when purchasing an electric weed eater.

1. Black and Decker GH900 String Trimmer

The Black and Decker GH900 String Trimmer is a great tool that features a powerful 6.5 Amp motor that can handle even the toughest-to-cut weeds and grasses in a single pass.  Its “Automatic Feeding System (AFS)” translates to a continuous feed of cutting string without having to stop or bump it against the turf.

The Power Drive high-torque transmission prevents it from bogging down during even the toughest of jobs, and its easy-grip, ergonomic design provides maximum comfort and control.

The Black and Decker GH900 String Trimmer, which can be adjusted to different heights depending on the user, works great as a weed eater, but it is also designed to be used as an Edger.  The trimmer is equipped with a 2-in-1, easy-conversion wheeled edging option.  To use this option, simply rotate the cutter head from the trimmer to the edger position.  From there, the product’s Smart Edge mode, which allows for greater control and accuracy, will enable you to put a clean, straight edge on any type of lawn.

Electric Weed Eater Buyer’s Guide:  What to Look for When Shopping

When shopping for an electric weed eater, there are several things you should look for – and several things you should consider.  Below we have outlined a few of these to help you get started:


Depending on the size of the job you plan to tackle, you may have to carry your weed eater for many hours at a time.  For this reason, it’s important you look for a model that is light enough to comfortably handle.


While the curved-shaft weed eaters work well for trimming back weeds, the straight-shaft models tend to work better for lawn edging and are safer because you can stand further back.  Once you decide how you primarily plan to use your weed eater, then you can decide on your preferred shape/design.


For large and tough jobs, you need a weed eater with at least 5 amps of power, but for light duty jobs you can get away with a lot less. The electric weed eater models we reviewed above supply between 1.8 Amps of power and 6.5 Amps of power.

Cutting Head Width

A larger cutting head – between 14 inches and 15 inches – will help you get the job done faster and with fewer passes.

Cutting Line/Line Feed

Cutting line comes in various widths.  Naturally, for large or tough jobs, you will need a weed eater that can accept thicker and more durable line.  Also, weed eaters with bump-style line feeders can be very frustrating and time-consuming.  They also tend to break with overuse.  Instead, try and look for a weed eater with an Automatic Line-Feed system.  These systems help to avoid the dreaded “spool tangles” that can waste 30 minutes or more when working.


Although all weed eaters can be used for edging (if you know what you are doing), you will notice that some of the models reviewed here can literally be transformed into easy-to-use edgers with wheel guides for precision cutting.  If edging is important to you, it pays to have this feature.

Other Features

Some electric weed eaters come with a variety of features that can help make your work go smoother and safer.  Some of these features include telescoping shafts for hard-to-reach areas; adjustable and pivoting handles; shoulder straps; and guards for keeping the electric cord away from the cutting line.
