Best Weed Eater Reviews 2017 – 2018

Weed eaters, also known as string trimmers or lawnmowers, are becoming more and more popular among the environmentally conscious consumers. What’s more, compared to older models, even gas-powered lawnmowers are far less polluting and wasteful of gas for practical reasons.

This is especially true in California, where it has tougher federal regulations on how much gas and waste a gas-powered trimmer can use up and emit respectively. To get these energy savers, you should make sure that their engines are certified to meet Californian federal regulations for 300 hours instead of just 50 hours.

Not only will you get less pollution from these trimmers, you can also have longer operating life out of their engine to boot. It’s literally a win-win scenario when you go green and care more about Mother Nature.

Best Weed Eater Reviews

Black & Decker LST136W 40V Max String Trimmer (BEST SELLER)

As the best seller of the weed eater bunch according to, the Black & Decker LST136W String Trimmer has a lot to live up to. After all, it is a Black & Decker power tool, which means it has to fall within the standards of one of the most famous and ubiquitous American power tool companies around.

The LST136W shows off its stripes by having a Power Command dial that allows you to choose the maximum runtime and power. As for the string trimmer’s Automatic Feed Spool, it is there to make sure that you can continuously operate the machine without worrying about bumping and interruptions.

If you’re worried about battery life, then take note that the Black & Decker LST136W has loads of energy from the 40-volt MAX lithium battery that should suit the needs of any residence or homeowner, even if you have grass so tall big cats like lions and tigers could hide in them.

Moreover, with a quick turn of the shaft of the LST136W, you can also convert the trimmer to an edger. That means you can get more versatility and flexibility from this electric string trimmer wonder.

You can also get the job of cutting your grass and mowing your lawn done faster thanks to this machine’s Power Drive Transmission that delivers more juice and power efficiency to your already impressive motor.

If you thought that electric string trimmers just can’t compete with gas string trimmers, then think again: The Black & Decker LST136W makes a compelling argument against that. Read our detailed review of the Black & Decker LST136W here.

Black and Decker LST420 High Performance Trimmer and Edger

Finally, the second Black & Decker of the list – the Black and Decker LST420 Trimmer and Edger – proves itself to be another convertible kind of trimmer with superior power drive transmission.

You could get as much power from its engine as possible while cutting grass, hedges, and vines down to size without having to invest in a chainsaw or huge grass-cutting shears. The Black and Decker LST420 is enough to suit all your needs.

The power of the trimmer and edger is distributed from motor to cutting string, so every cut is even and smooth all around. In many ways, the Black and Decker LST420 is a gift that keeps on giving (or a trimmer that keeps on trimming).

As cliché as it might sound, the machine really does have the ability to cut through organic matter like a whirring hot knife through butter; the 2-in-1 Black & Decker LST420 Trimmer is truly amazing. Although it doesn’t appear as impressive on paper as the WORX WG175 (which has an extra mini mower transformation), the LST420 more than makes up for it with an automatic feed spool, runtime extension technology, a 2-amp and one hour lithium battery pack collection with each battery delivering 33% more energy than the LBXR20 battery pack, and the 20-volt MAX system that has a battery that can fit your other battery-powered appliances on your toolshed.

CORE GasLess Power CGT400 CGTSD

CORE GasLess Power CGT400 CGTSD Gasless Powered Trimmer

The main claim to fame of the CORE GasLess Power CGT400 can’t be narrowed down to just one feature. This multifaceted beaut of a gas-less (electric) power trimmer ensures ecological grass trimming just short of using an old-fashioned scythe to cut down your grass to size.

More to the point, the CORE GasLess Power CGT400 CGTSD has dual-mode power control speed reserved for quality trimming action on regular yard work jobs or optimum performance and a longer run time with its extra torque option if you so choose. Meanwhile, its cutting-edge prismatic high-energy power cell operates in harmony with its new smart core electronics to make it more sophisticated at cutting your lawn grass in a completely controlled fashion. You’re the one that’s always in control.

You’ll never feel like the CORE CGT400 has a mind of its own. What’s more, it runs for 1 hour and 10 minutes every time, so it has the operating time of a laptop at the lowest energy settings essentially. This is more than enough time to get your yard work done before the next recharge for sure, especially when you take into consideration the trimmer’s amazing 5,000 RPM torque and 7,000 RPM speed.

In fact, the machine has 25% more torque than a commercial trimmer that’s twin-cycled and runs at 25 CC. If that’s not enough to amaze and wow you, then how about the electric string trimmer’s head-type dual-line bump feed and trimmer line that’s 0.095 in diameter and is 20 inches on spool?

The machine has everything you’re looking for in an electric trimmer and then some! What more can you ask for? Read our detailed review of the CORE CGT400 here.

Husqvarna 128DJx String Trimmer

While electronic or electric mowers and weed eaters conserve energy and natural oil resources better, there’s still nothing like a good old-fashioned gas string trimmer such as the Husqvarna 128DJx Gas Powered String Trimmer when it comes to heavy-duty cutting of Amazonian jungle tall grass that you’d need grazing sheep to get rid of.

There are certain jobs that the string trimmer mower or electric string trimmer can’t do that the gas string trimmer could. Otherwise, you need to invest in a machete, big shears, or a scythe to get your tall grass short enough for a mower or electric trimmer. With that said, the Husqvarna 128DJx is CARB-compliant.

What that means is that even though it’s gas-powered, it also conserves and maximizes its output per fuel intake so that there are fewer emissions and more efficient burning of that gasoline (that translates to a better job at cutting your grass down to size all-in-all). For a gas-powered weed eater, it has all the bells and whistles of an ecologically friendly piece of equipment.

It’s easy to start thanks to its smart start feature, it has a convenient fuel pump, and it sports an auto-return stop switch that allows you to easily start it whenever you need it. Meanwhile, it reduces its exhaust emissions through its E-Tech II feature.

As for the Combi-Guard, it’s used for both the grass blade and the trimmer line for more effective cutting and less residue flying into your face. The Husqvarna 128DJx even has a harness that assures you of better control of the machine as you operate it. Read our detailed review of the Husqvarna 128DJx here.

GreenWorks 21142 Corded String Trimmer

Last but not least is the GreenWorks 21142 10Amp 18-Inch Corded String Trimmer. This weed eater’s main claim to fame is that it accepts most gas attachments so that it serves as a versatile, multifunction tool that provides multiple types of uses.

It’s also quite powerful thanks to its 10-amp motor with a .08 dual-line bump feed and straight shaft. Another notable thing about the GreenWorks 21142 is its large 18-inch cutting path that speeds up your trimming operation every time, plus it’s lightweight and can be started easily with a push of a button through its simple electric start mechanism.

Meanwhile, the GreenWorks 21142 String Trimmer also comes with a cord-lock feature that makes it safe and easy to use. You’ll avoid many potential injuries thanks to all the safety precautions and measures of the 21142. It’s also compatible to Model 29622’s Replacement Spool so you won’t have to look far and wide to get the right spool for this trimmer.

Many reviewers agree that you can rely on this corded string trimmer because it really does belong to this list of quality weed eaters that are highly recommended for your usage and consumption. It’s definitely something that will last you a long, long time. Read our detailed review of the GreenWorks 21142 here.

WORX WG175 Cordless Grass Trimmer and Edger

While it’s no Black & Decker or Husqvarna, WORX has undeniable quality specs that make it stand out (like its fellow company that’s exclusively known for weed eaters, CORE). To wit, the WORX Cordless Grass Trimmer comes complete with a quick-release lever and 90-degree tilting shaft for quick telescopic height adjustments, a 12-inch cutting diameter with no bumps and 100% single-line feed, a lithium power battery with a maximum power grade of 32 volts that provides longer runtime and high power, and versatility through trimmer-to-edger conversion in seconds without the use of any tools.

Its main claim to fame, however, is its 3-in-1 function that allows it to use dual-positioning wheels for easier weed-eating, grass-trimming action every time. It’s capable of mowing, edging, and trimming in one power tool.

Furthermore, the WORX WG175 will prove to become a beloved edition to your toolshed because it brings mowing, edging, and trimming to a whole new level. It might even give certain gas-powered offerings out there a run for their money while at the same time having superior energy-conservation and emission-mitigation (as in zero emissions, in its case) benefits.

It’s easy to use, easy to turn on, easy to transform from mower to edger to trimmer, and it has a generous cutting diameter which means that even if its power is limited compared to a gas trimmer or a lawnmower with a long extension cord, it makes short work of many huge lawns anyway for the time limit to matter. It’s also cordless, so you can go as far as you can in cutting down your lawn without worrying about unplugging anything.

Weed Eater Buying Guide

Reasons for Buying a Weed Eater

Every lawn has its own individual requirements. Each of them has their own circumstances and needs. Yards and yard work should be approached on a case-by-case basis. The same goes for homeowners or gardeners who have to take care of these gardens. There are weeds that are tougher to remove with shears or by uprooting compared to others, so you should definitely buy a weed eater to deal with them in an effective fashion.

You should figure out what kind of weed you’re dealing with and if you have the right grade of weed whacker or lawnmower to assist you in your yard work requirements. How intuitive and comfortable the weed eater is can be a major factor in your trimmer shopping for sure. Take a look at the device’s handle to ensure that it has an ergonomic grip that won’t leave your hands chaffed and bleeding when everything is said and done.

When shopping for the right weed whacker or lawnmower, it’s always all about picking the one that feels right. It’s hard to explain, but once you start using a weed eater, you’ll immediately know which ones are easiest to use in accordance to objective results you can get out of them and also to your own personal tastes. How a trimmer handles in your grasp all depends on its balance.

It’s also a case-by-case basis type of feature since certain mowers work differently than others in relation to your height and weight. You shouldn’t get a lumbering, unintuitive device that feels cumbersome when you use it. It should instead have a comfortable reach when you hold the trimmer in the cutting position (although many of them have front handles that can be adjusted according to what you want). You should be able to push it forward like a two-wheeled wheelbarrow with both of your hands.

Things to Remember about Weed Eaters

When buying a weed eater, you should also buy a visor. Weeds are usually trimmed at high speeds, thus the cut weeds could fly right at you, specifically your face or even your eyes. Having visors or perhaps goggles should safeguard your face and eyes.

It can also protect you against flying stones, pebbles, splinters, and other such materials that turn into unintentional projectiles as you go about mowing your lawn in peace.

Aside from eye protection, you should also wear gloves and long pants when using your weed trimmer or mover. Safety should be a top priority of yours. You should also have ear protection. You can use an iPod or ear mufflers that you can soundproof your ears from a trimmer’s loudness (many of which emit at least 85 decibels save for the cordless electric models). What’s more, its weight should be evenly distributed from top to bottom or at least with slight top-heaviness.

The reason for this is because you want to be able to control it in a balanced fashion from the front handle without letting the bottom parts overpower you. The controls should also be easy to reach while working smoothly at the same time. You should check the gap as well since weeds ad tall grass can stall or slow a trimmer. Perhaps you should use your shears first or perhaps you should check the gap since these weeds can wrap around the top of the mower’s cutting head.

More to the point, if there’s a gap between the mounting for the grass-debris guard and the cutting head, then it’s more likely to make the grass get tangled into its blades. Therefore, when buying a weed eater, you should definitely look for the models that sidestepped this issue by having a protective sleeve or smaller gap between the cutting head and the grass-debris guard. 

Types of Weed Eater

Gas String Trimmers

A gas string trimmer is more powerful than electric weed eaters for the simple fact that it makes use of gas. If you have a jungle for a yard or lawn, then it’s a good choice to go the grass string trimmer route to handle all that heavier growth or huge lawn area (like mowing the grass of a golf course, perhaps). Gardeners love them because they offer long run times and loads of mobility for something so powerful.

With that said, like many gas-powered tools, it’s a pull-start kind of device. You have to pull the cord to rev up the engine the same way you’d start a car or a motorcycle. You can also avail of models that are easier to start thanks to a powered device setup that you can buy separate from the weed eater, thus eliminating the need for a pull-start in the first place. Grass trimmers require the right fuel and can only handle certain levels of ethanol.

String Trimmer Mowers

As for this iteration of the lawnmower or weed eater, it’s a trimmer that’s effective in areas that are hard to reach with a full-sized weed eater on the level of a gas-powered string trimmer. It’s also the ideal mower compared to handheld trimmers when dealing with jobs that are too much for them to handle. This piece of equipment is an expert at maintaining the length of the grass just right at the average lawn.

When you think of lawnmowers, the first thing you visualize is what the string trimmer mower is. It can do all sorts of weed-eating work without being so small that it’ll get overwhelmed by a yard that hasn’t been cut in a month or so. This is also a gas-powered mower, but it isn’t single-handled and features wheels, unlike the gas string trimmer. Aside from mounting its trimmer head on a wheeled body, it also offers superior power and mobility that’s only outdone by the heavy-duty gas string trimmer.

Electric String Trimmers

The third type of weed eater looks a lot like the gas string trimmer but is instead powered by electricity (you need to plug it into your electrical socket to recharge it after use). Compared to gas models, this string trimmer variant is easier to start and maintain. You don’t have to pull a cord to start it and you can maintain it better since it’s more of an electrical appliance than motor-running equipment like vehicles or certain power tools (air compressors and chainsaws).

You also don’t have to deal with noise pollution or air pollution when it comes to these weed eaters, but it comes at the price of raw cutting power. Corded electric trimmers will give you constant power as long as they’re plugged into the socket. Cordless electric trimmers have a more limited operation time due to their battery life, but it comes at the benefit of not tripping unto cords and extensions or unplugging them by accident. 

In Summary

The downside to buying ecologically friendly trimmers is you have to pay upwards of $200 and beyond to get these weed eaters. That’s because they’re premium trimmers of the highest caliber that doesn’t compromise when it comes to wastefulness reduction and less emissions all-in-all.

When shopping for corded weed eater machines, you should go with those that can tackle tall grass, trim, and edge out your lawn in a manner that’s as impressive as a gas-powered mower.

Meanwhile, when buying a cordless weed eater, you have to be aware that there’s sometimes a tradeoff between mobility and quality. The more mobile something is, the less effective it is at doing other stuff, like battery-powered trimmers having less ability to hack away tall grass (one exception to this rule are smartphones that can seemingly do anything and everything).

With that said, there are some battery portables that can do a decent job at trimming even the toughest weeds usually reserved for their gas-powered counterparts. When shopping for the right type of mower or string trimmer, you should let your needs dictate what you’ll ultimately end up with.

Electrical string trimmers (either corded or cordless) provide the most environment-friendly solution but at the expense of power, with cordless covering a longer area without the use of extension cords. Gas-powered string trimmers are only reserved for jungle-like lawns that haven’t been cut in ages since they’re harder to maintain.

The lawnmower or string trimmer mower is the perfect balance between the two extremes, although it’s also gas-powered but easier to push around thanks to its wheels. Follow the manufacturer’s requirements when it comes to fueling the gas-powered trimmers on this list.
