    What Are Weed Whackers?

    We’ve all heard the term “weed whacker” or “weed wacker”…but what image springs to mind when these words are spoken?

    For most of us, it’s just a nondescript piece of machinery.

    Most people have no idea what this hunk of metal actually does—and that’s okay, because we’re here to tell you. Essentially, the weed whacker’s job is to eliminate difficult-to-reach weeds which grow in the tough corners of yards and drivers.

    How Does a Weed Whacker Work?

    Weed whackers can be complicated machines, but they work based on a simple premise.

    They utilize an energy source like a battery, gas engine, or electric engine which moves the head. Attached to the head are long, tough strings which spin quickly and build up enough momentum to slice through the stems and leaves of weeds.

    Strings vs. Chains

    Chains are naturally stronger, but are banned in many places because of the danger involved. At least one person died from being hit by the moving chains, so it is safer to invest in strings or plastic lines. Another problem with the chains is that pieces of the metal can detach and become shrapnel from flying several hundred feet through the air.

    String trimmers continue to be popular because they are inexpensive and easy to replace. The strings also pose few health risks unless someone comes in contact with them while the whacker is on.

    Gasoline vs. Electric

    Weed whackers powered by gasoline tend to be more expensive than electric versions, but also more powerful.

    For comparison, a stronger gas-powered model can cost hundreds of dollars while a small, weaker, electric version can be purchased for under a hundred bucks. Both models, of course, have different benefits.

    Gas trimmers work best on difficult types of terrain which feature a lot of rocks or brush. Many of these models can have their string heads replaced with others that have circular blades for cutting through thick brush or saplings.

    Electric trimmers work well for the typical homeowner who has a smaller yard to maintain. These simple models are useful for clearing up weeds around gardens, driveways, and regular lawn decorations.

    To listen to the difference between these two motors in action, take a quick peek at the video below.

    The best trimmer will depend on what kind of yard you have and how you plan on using the device.

    Is It Dangerous to Use a Weed Whacker?

    The main risk of using a weed whacker is accidentally getting clothes or flesh tangled in the strings.

    The University of Arkansas Division of Agriculture recommends that users wear tight clothing, boots, eye protection, and long pants. Ear protection is also valuable, as these machines roar pretty loudly.

    Another problem many users encounter is that they sometimes hit rocks or sharp sticks with the machine. The object could go flying and collide with someone, so it’s important to clear the area before turning the whacker on.

    What Makes a Quality Weed Whacker?

    As with any piece of machinery, a quality weed whacker is one that works but also doesn’t pose too much of a safety risk to the user.

    Some styles have been banned in several countries because of their safety hazards, so a string weed whacker is considered best. Otherwise, it’s important to choose a device with a power level suited to your yard.

    How Much Does a Weed Whacker Cost?

    Here’s where the waters get murky: sometimes, you’ll see weed whackers for just a few bucks. Sometimes, they’ll go for several hundred.

    Long story short—you get what you pay for.

    A weed whacker usually has a long lifespan, so buying one should be an investment that lasts several years. Cheaper models are usually more likely to break or are not as powerful as their more expensive counterparts.

    To view up-to-date prices on recommended models, see our buying guide below.

    Do Weed Whackers Work?

    When used properly and safely, weed whackers get the job done with ease and precision.

    What makes a weed whacker advantageous over a tradition lawn mower is its flexibility; because it’s a handheld device, the user can get to tight spaces with so much more ease than with a clunky, awkward push-mower.

    The owner should always take care to read the instructions carefully before operating any type of machinery.  As always, use best practices for safety while operating machinery.
