Introduction to Weed Eaters

Whether you maintain a garden as a homeowner or a landscaper, you’re probably going to have to deal with weeds. Weeds are plants that are unwanted because they kill other plants or ruin the look of a garden. There are many methods that are used nowadays to remove weeds from a garden whether it’s with weed killers, manually pulling them out, using garden shears or our topic for this article, using a weed eater.

Weed eaters, also called weed whackers, line trimmers and string trimmers, are high powered gardening tools that are used to rapidly cut grass and weeds. Weed eaters use a thin plastic line which is attached to a rotating spindle located at the bottom of a pole. When powered on, the spindle whorls the thin lines at incredibly fast speeds that slice through foliage. Weed eaters are one of the most commonly used powered gardening tools in landscaping next to lawn mowers and are great for medium to large sized lawns that have a lot of ground to cover.

Weed eaters have been around for a while and new developments are being made year after year. Companies have found ways to make weed eaters stronger, more efficient and even include features that would change the game entirely. If you’re new to weed eaters, we’ll be covering all of the basic features that you’ll likely run into and more down below. So, without further adieu, let’s get into our list of the best weed eaters available online.

Buying Guide for Weed Eaters

Types of Weed Eater

Weed eaters come in different shapes, sizes and even have different power sources. In this segment, we’ll be explaining the most common types of weed eater you’re probably going to run into in your search for the best one.

Gas Powered

Similar to most medium sized machines used in gardening, the early weed eaters were originally gas powered. Having a gas engine has several pros and cons. Gas powered weed eaters are significantly more robust and powerful than their electric powered cousins. Gas powered weed eaters also tend to struggle less when cutting through thicker grass. Surprisingly, gas powered weed eaters are similar in weight to their electric counterparts despite the more durable construction. The cons of gas powered weed eaters are pretty clear. Being gas powered, these weed eaters are pretty loud. We’re talking about at least 100dB or as loud as a chainsaw. Gas powered weed eaters also emit dangerous fumes that could cause respiratory issues further down the line. Gas powered weed eaters also require more maintenance than electric alternatives.

Electric Powered 

There are two main types of electric powered weed eaters in the form of corded and cordless models. Let’s see how the two compare.

Corded weed eaters have some advantages and disadvantages compared to both cordless and gas powered models. For one, corded weed eaters are much quieter than gas powered weed eaters and don’t emit any harmful gasses. Corded weed eaters are also maintenance free and have no need for fuel or oils. Corded weed eaters will typically have motors that are 5 Amps or higher. This is enough power to power through most tall grass and some manufacturers even refine these motors to increase torque. These refined motors can give some corded weed eaters a cutting speed rivaling those of gas powered weed eaters. Given that these are corded tools, users would need a nearby power outlet or to invest in an extension cord to cover more area. This is one glaring con and because of this, corded weed eaters are usually used by homeowners with smaller lawns.

Mobility is where cordless weed eaters shine. These use Lithium Ion batteries and have the advantage of being highly portable. You’d be somewhat correct in thinking that batteries don’t offer as much power as corded or gas powered weed eaters but with battery technology getting better every year, it’s only a matter of time. An obvious issue with battery powered weed eaters is that you’ll eventually need to recharge the battery, leading to more downtime. To solve this issue, some companies include two or more batteries so that you can just swap out batteries when one dies. This can be a con as well because the price of a good battery can be quite high.

Important Factors

Weed eaters can be complicated machines. They can have complex features and parts that help the user get the job done faster. Here are some important factors that you should consider before buying a weed eater.

Cutting Path

The cutting path of a weed eater refers to how wide of a path the lines can cut. The width of the cutting path is limited by the protective shield that surrounds half of the cutting diameter and prevents debris from flying at the user. Most weed eaters will have cutting paths anywhere from 10 to 20 inches wide. 

Motor, Battery & Engine Size

The motor and engine size are two measurements used to determine how powerful a weed eater is, specifically corded and gas powered models. On corded models, the motor size is often translated into amperes or Amps for short, with most corded weed eaters having motors ranging in size from 5 to 10 Amps. For gas powered weed eaters, the size of the engine is determined by its displacement and is measured in liters and cubic centimeters or CC for short. Most gas powered weed eaters have engine sizes ranging from 28cc to 50cc. Cordless weed eaters use batteries as a power source and thus, are measured in voltage and amp hour or V and Ah for short. Most cordless weed eaters use batteries that are at least 20V and have amp hours of 2.0 Ah or more.

Feed & Line Type

The feed and line type of weed eaters refers to how the line is installed onto the trimmer head. There are two main types of feed types in the form of bump fed and string fed systems. 

A bump feed line system has a spool of line that can be manually adjusted by the user. When the existing length breaks or is worn out, the user simply has to take out or open the reel and extend the line to the desired length. Newer models have automatic feeding systems that use small motors inside the trimmer head to keep the length of line consistent.

A string fed system on the other hand, uses pre-cut lengths of line that are individually inserted into the trimmer head. String fed weed eaters are relatively easy to maintain when the line breaks but relies on the user to have some spare lines nearby. String fed weed eaters also require users to be more careful with how long of a line they insert as having a line that is too long can damage the protective shielding. 

Weight & Ergonomics

The weight and ergonomics of a weed eater are important factors to consider because it will determine how comfortable and controllable the weed eater would be. Weed eaters are typically 30 inches long, or more, and weigh below 20 lbs. This may seem pretty manageable but also consider that these are powerful tools that have a cutting head that spins at thousands of rotations per minute. Not to mention, you’ll also have to consider how long it’ll take for you to trim the whole area. A couple of pounds may not seem like much but even a 10 pound weed eater can be tiring to use after 20 minutes of lawn trimming under the sun. 

Manufacturers take these into account and include features that make their weed eaters easy to use. This includes an auxiliary handle that you can use to have more control over the weed eater, ergonomic grips that make it easier to hold the weed eater for long sessions,  adjustable trimmer heads that let you angle the weed eater and even telescopic shafts that lets you adjust the length of the pole.

Parts of a Weed Eater

Trimmer Head

The trimmer head of a weed eater is where the line will be housed. Trimmer heads can be bump fed or string fed. A bump feed trimmer head will have a housing specifically for the spool while a string fed trimmer head will have locking inserts for the line. Trimmer heads are built to be the sturdiest part of the weed eater because of the material they are meant to cut along with the flying debris that’ll be caught in the whorling of the lines as it passes over them. Learn how to replace trimmer line here.

Trimmer Head

The shield of a weed eater ensures that the user is protected from any flying debris that might be thrown around by the trimmer head. These are designed to be sturdy yet lightweight enough to not impede on the mobility of the weed eater. The shield is usually a half circle that covers half of the cutting path but some manufacturers make these shields smaller.

Auxiliary Handle

This part of the weed eater helps the user have more control over the weed eater. Auxiliary handles are wider than the shaft and grip so that users can hold them in whatever position they find the safest or most comfortable.These are typically covered in a rubber overmold that also helps make it more comfortable to carry.

Auxiliary Handle

This part of a weed eater holds the essential controls such as the power switch, variable speed controls and the trigger. Depending on the model, the motor or engine can be located below or behind the grip. Cordless models mostly have the battery insert located by the grip as well.



Q: Would a lawn mower be better than a weed eater?

A: Both a lawn mower and weed eater fulfill similar roles and have their pros and cons. A lawn mower is better at making even cuts on a lawn than a weed eater but using a weed eater gives you more control over how deep you want to cut. A lawn mower can cover more ground faster than a weed eater but a weed eater is better at cutting on an inclined surface. In general, both of these tools are good at what they do and whether one is better than the other depends on factors such as location, how much ground you have to cover and budget.

Q: Are weed eaters safe?

A: As we mentioned, weed eaters are powerful tools that can be capable of causing harm if not used properly. Weed eaters should be used responsibly and not in areas with people nearby that can be hit by debris. It’s also best to use weed eaters with gloves and safety glasses for your own protection. If you follow basic safety etiquette, weed eaters should be safe to use for any adult.

If you’d prefer a hand tool, grass shears can work too, but are tedious to use and keep sharp.

Q: Are weed eaters expensive?

A: This depends on the brand, engine or motor size, material that the weed eater is made of and features that the manufacturer includes. On average, weed eaters can cost anywhere from $50 to $500.


Weed eaters can be a great addition to your gardening tool kit. We hope that this article taught you a thing or two about weed eaters and that you leave here with a better understanding on which one you think is best for you. Thank you dear reader and happy gardening!
