The Buying Guide for the Best Weed Wacker

The Buying Guide for the Best Weed Wacker

It’s great to have a nice yard and garden, isn’t it? It makes your home and property so much more attractive. On the other hand, you do need to maintain your yard properly, and often, that means you need to find the best weed wacker to do the job for you.

Weed wackers, also commonly known as string trimmers, use plastic lines to trim areas of the yard that need it the most. This includes getting rid of those pesky weeds growing up in the cracks of the driveway and sidewalks and achieving a perfect edge on the other areas of your property.

It is a convenient power tool to use for lawn care and maintenance and helps when the area you need to get rid of grass and weeds is just too irregular to mow or get to with a lawnmower.

Factors to Consider

You really want to avoid the overly cheap weed wackers, since they won’t get the job done. That’s the main point, so you need to save up to get the proper unit that will do the best job possible for your yard. Here are some considerations that must be factored in before you make your final choice:

Gas-Powered, Corded Electric, or Battery-Powered

The kind of weed wacker you get is the first major choice you need to make. Each one has its own set of pros and cons, and so you need to make sure that your choice matches your circumstances.

Gas powered weed trimmers are capable of cleaning up a much larger yard and has a large cutting swath of 16 to 18 inches. However, gas-powered weed trimmers tend to be on the heavier side, they are a lot noisier, and they also require far more maintenance. You always need to have gas and oil on hand.

Corded electric weed wackers offer something that is lighter in weight, and they come at an affordable price. However, a corded electric weed wacker will probably not be useful for sawing brush, and you may find a limited cord reach.

Battery powered trimmers can handle smaller yards, and they are lightweight and easy to take wherever you need them. They also typically come with a rechargeable 12-volt battery, so you don’t have to be limited to the length of an extension cord. You can also purchase spare battery packs, so you always have a backup available when you need it.

Ease-of-Use Features

This factor includes how easy it is to start up, which is crucial for notoriously hard-starting gas-powered weed wackers. You’ll want to check how easy it is to put in oil and water, or if the batteries can last long enough for you to get the job done. You also need to check the spool type and see if it advances the line automatically and if it’s easy to replace the spool.

For an item like this, it is really highly recommended that you stick with well-known brands. That’s so you don’t waste time and money dealing with substandard quality. Famous brands have spent years establishing their reputation, and you’re better off by picking a famous brand than some unknown manufacturer. This isn’t brand snobbery—it’s just plain common sense.

How well does the weed wacker do the job it’s supposed to do?

With this factor, the gas-powered models are your best option, because they offer powerful motors that can provide high rpm that can deal with any type of vegetation you use it on. Also, you have to consider the swath diameter, as a bigger one will obviously get the job done faster. You should also check if it can work as an edger too, or if you need to buy attachments to make this switch.

This is about how well you can handle the weed wacker so you can do the job comfortably. It helps if you can adjust the length of the handle, and of course, it’s also easier for you if it isn’t too heavy. For heavier models, you may need to check if it comes with a shoulder harness, which can add support and control. It also shouldn’t vibrate too much.

The importance of the brand can’t be overestimated, which is why we made sure that each of our recommendations is from well-known manufacturers. If you’re looking to buy the best weed wacker for the money, you may want to start your search with these 5 excellent branded choices:

BLACK+DECKER LST300 Weed Whacker

This is a battery-operated trimmer that can convert to an edger in just a few seconds. So right away you know that you don’t need to deal with fumes and fuel mixes, and you won’t have to bother with cumbersome cords.


  • This uses the 2.0 Amp hour lithium-ion battery pack
  • The motor can go up to 6200 rpm
  • It features an automatic feed spool
  • The height and handle positions can be adjusted
  • It weighs 5.7 pounds
  • The cutting swath is 12 inches
  • It also offers a guard on the head so that you and your pretty flowers are protected
  • It converts to an edger easily


  • The battery is an improvement on the previous version. It also uses the same type of battery that you find in other cordless Black and Decker power tools. You can charge those other batteries fully so that you’ll have an endless supply of portable power if you have a large yard to maintain
  • It’s more comfortable to use since the height, and the handle can be adjusted. This makes storage a lot easier, as well
  • The light weight of this trimmer not only makes it comfy to use, but you’re able to control it much better
  • You do have ample power to trim grass and weeds with no trouble
  • Changing to the edger function doesn’t take more than a few seconds


  • The single battery can last for just 25 minutes or so. That’s a problem if you have a large yard and you don’t have spare batteries because you don’t have any other Black and Decker cordless power tools. This means you’ll have to buy a spare battery pack for backup
  • Like most battery-powered trimmers, the power may not suffice for more stubborn stalks and vines. Other types of stubborn weeds may also take several minutes, compared to the few moments needed with a gas-powered weed eater. You may want to change the installed string with an edged version for better cutting performance


This works well enough if you have a small yard to maintain, and it makes perfect sense if you’re also a frequent buyer of other Black and Decker cordless power tools. Just get an edge string to improve the cutting ability, and you can really enjoy the quiet and the fresh air.


WORX WG163 GT 3.0 20V Cordless

WORX WG163 GT 3.0 20V Cordless

Once again, we have a trimmer that turns into an edger easily, and it’s powered by a rechargeable 20V battery pack. Again, you can enjoy not having to deal with a long cord, nor do you have to put in gas and oil, or contend with a lot of noise, and noxious fumes.


  • This uses a Max lithium power battery, but this purchase comes with 2 of them. What’s more, this is the battery that’s used for the 20V Worx Power Share System. This means that if you have other cordless Worx power tools in your shed, you can use those batteries for this trimmer
  • You have a 12-inch wide cutting swath
  • Converting the trimmer to an edger only needs a simple pull so you can turn the trimmer head. Once that’s done, you can just turn it to lock it securely. Now you have a wheeled edger for sidewalks and driveways
  • You have 7 preset height settings to choose from. With these presets, the handle clicks into place, so it stays that way as you use it
  • As for the weight, it’s just 5.3 pounds
  • There’s no bumping here needed to advance the line, as it uses the “Command Feed” spool system
  • The flower spacer guard lets you trim the grass and weeds without touching the flowers in your garden. It also works as the edger guide when you’re in edger


  • With 2 batteries you have a backup power supply available so you can work longer without waiting to recharge the batteries. You also get lots more batteries to use if you have lots of other cordless Worx tools
  • The battery runs for 20 to 30 minutes, so 2 batteries can give you up to an hour of trimming
  • It’s nice that it turns into an edger very easily
  • With the preset height settings, you’re able to pick one that lets you control the trimmer most effectively and comfortably. It also helps with control and comfort that it’s so lightweight


  • It takes about 3 hours to fully recharge the battery. So, even having two batteries, won’t allow you to use one while charging the other one indefinitely.
  • The cutting ability obviously won’t deal with tougher stalks and vines.


This is like the Black and Decker cordless in most ways, though here at least you have an extra battery as part of the purchase. However, this really makes a lot more sense if you already have other cordless Worx tools at home.

Trimmer Technique

If you aren’t careful and you trim too close to the surface, you may end up stripping the lawn bald. To trim more effectively, you need to make sure to keep the trimmer at least two to three inches off the ground. You then sweep the trimmer side to side in a steady motion while remaining parallel to the ground. It is easy to do once you learn the technique and practice it.

If you are faced with overgrown and tall grass, it is easy to get the trimmer’s strings tangled up. Always trim the taller weeds down before using the trimmer, so the strings can do their job more effectively without becoming tangled up and damaged.

It may take a bit to achieve a clean edge along the driveway or other areas, but once you achieve the edge you want, it is very easy to maintain.

Cleaning Your Trimmer

When you are done with your trimmer, it is important to wipe off all the grass and other debris that may be on it. You should also check the gas level and inspect the string to see how much is left. If it has a cord, neatly coil it.

If it has a battery, be sure to recharge the batteries. If it is gas-powered, you want to make sure that you store the trimmer vertically (upright) so that the fluids don’t leak.

Final Verdict

So, which one is the best? With our list, we stuck to famous brands to make sure they all work very well, and they won’t break down easily. The most obvious answer to that question is simple: it’s up to you. You need to address your primary concerns.

If you’re just trimming grass and you don’t want to make a fuss, then you’re probably looking at the cordless models that don’t make a lot of noise.

Yet if you really want to get the job done right, you should really consider the Husqvarna 128LD. This thing is a beast. Yes, it’s a lot noisier and heavier than your battery-operated options.

You’ll need to buy an attachment to use it as an edger, while ear protection is a must. You will also need to deal with mixing gas with oil, and the resulting fumes as you use it.

But this is still without a doubt your best option, as it offers you contractor-grade performance that can deal with any type of vegetation on your lawn that you want to trim and cut.

At the same time, you’re not faced with an intimidating set of features that’s common for other professional weed wackers. This one is extremely easy to use even for ordinary homeowners.

So, buy the Husqvarna 128LD if you have a sizable lawn and tough stalks to deal with. You won’t have any trouble cutting the yard, and you’ll get the job done more quickly. That’ll give you more time to relax in a lounge chair while you look out and admire your beautiful yard.
