All weed eaters have similarities, including having a primary purpose of trimming weeds and areas where you can’t reach with your lawnmower, around the edge of the rock garden for instance. But there are differences between cordless, electric, and gas weed eaters that you will need to know.

Cordless weed trimmers are a form of an electrical weed eater, but instead of needing to be plugged up, they run off lithium-ion batteries.

You start these trimmers with the push of a button instead of having to pull a rope. But it has the same accelerator that controls the cutting head.

Cordless weed eaters usually have a run time of thirty to sixty minutes, and you can use them anywhere without the pain of extension cords or adding fuel.

The Dewalt DCST925M1 is a 20-volt cordless weed eater that works with any 20v Dewalt battery. There are high and low speeds so that you can alternate between more power or longer runtime.

Electric weed eaters are better for people who don’t want to pull a string to make it crank. All you have to do to start it is push the button.

Electric weed eaters are better for the environment, but some limitations, such as needing a power source to run. There is a male electrical connection towards the top that plugs into an extension cord.

If you’re trimming in a rural area without power, you could run into trouble unless you carry a generator. Gas or battery-powered weed eaters would work better for large jobs.

Electric powered string trimmers work the same as a gas or cordless trimmer in that there is an accelerator that makes the cutting head spin. But this type of weed eater does have less power, 1200 watts max.

Black+Decker String Trimmer

Black+Decker is a popular tool manufacturer, and its electric string trimmer is top of the line. This weed eater has a 6.5 amp motor with a 14” shaft.

A cord retention system means you don’t have to worry about coming unplugged while you’re walking. But the plug is recessed into the machine so it won’t work with some three-prong extension cords.

And the automatic feed spool means you don’t have to tap your weedeater to load more string. It loads as you trim, and you refill the spool using 0.065” round line when the line runs out.

Gas Weedeaters

Remington RM25C 25cc 2-Cycle 16-Inch Curved Shaft Gas String Trimmer, Orange
25CC GAS ENGINE: QuickStart technology Engine to make pull starts easier.; Engine Type: 2-Stroke

Gas-powered weed eaters have a motor that runs on gasoline. Gas weed eaters can have a two-stroke or four-stroke engine.

It is crucial to know which motor you have, as two-stroke engines need gas to oil mixture to run, whereas four strokes only need gas. The two-stroke is the most common home tool, whereas four-stroke is better for industrial use.

Improperly mixing the oil to fuel ratio or not including oil can make a two-stroke engine seize up and stop working. Your mixture needs to contain one bottle of two-stroke engine oil (2.6 ounces) with one gallon of gas. If you’re using two gallons of gas, you’ll need two oil bottles and so on.

Husqvarna 128LD

One of the best gas-powered weed eaters is the Husqvarna 128LD 17” String Trimmer. This 28cc two-stroke engine has a 17” trimmer head.

And it’s equipped with a handy Tap ‘N Go feature that releases new lines by tapping the head on the ground. Adding more line is a breeze with the detachable T25 head that is easy to spool.

This weed eater has a 17” cutting width that helps you trim larger areas less time, and cut down more rigid materials.

Easy start technology and 2-step starting (prime and pull) make it easier to crank without a lot of effort or wasted time.

This weed eater has a fixed-line head that takes a 0.95” tri-color round line which helps cut under bushes or hard to reach areas. 

Battery Powered Weed Eater vs Gas

The big difference with a cordless machine is the NOISE! You can almost (but not quite), relax while using a battery powered weed eater, while using a gas powered model can be somewhat traumatic until you become accustomed to the noise and the fumes. Your neighbours will definitely thank you for choosing battery powered!

What is a Weed Eater?

Weed eaters, also called weed whackers, are a form of string trimmer, which means it uses a durable, flexible plastic string trimmer line to chop down weeds and grass instead of actually removing the weeds.

The design of a string trimmer is the same, regardless of which type of weed eater you choose. There is a cutting head on the bottom, a long shaft, and a handle at the top to move the machine. Some trimmers also have a shoulder strap, but lighter weed eaters will not.

Weed eaters work by a wire or plastic line wound around a rotating wheel. As the wheel spins, centrifugal force causes the line to stiffen enough to perform the cutting. While all weed eaters have the same setup, you can choose different sized lines, depending on your needs.

String trimmers also have a clutch or accelerator that controls the engine. This lever is near the handle for easy access. Once you start the machine, you use the lever to speed the motor up or make it idle, where the engine stays cranked, but the head is not spinning so it won’t cut.

After finishing the weed execution, you can easily clear all the mess using the best backpack blower available, these tools make life so much easier than having to use a rake or broom!

Conclusion of Cordless vs Electric vs Gas Weed Eaters

We’ve explained the three different types of weed eaters and provided details about each of them. Which choice you make will depend on your needs. One more way of dealing with weeds in a lawn, is to pull them up with a manual weed pulling tool. This is also a very quiet method, which would keep your neighbors happy, but may not be so kind to your back!

An electric weed eater wouldn’t work well in rural or industrial conditions. In comparison, a cordless weed eater would work in rural areas but not for all-day use. Gas-powered weed trimmers work best for commercial use.
