The Greenworks 18-Inch 10 Amp Corded String Trimmer is the best electric string trimmer for the value it provides.
You’ve been trimming the grass and weeds in your garden with shears but it’s hard work.
That’s why you want to invest in a good electric string trimmer that gets the work done fast and with ease.
But there are so many choices out there and you don’t know which one to buy. No worries, because we’ll show you exactly how you can pick the best electric string trimmer you need.
What is an electric string trimmer?
A string trimmer is a tool that can help you trim grass, small plants, and weeds. An electric string trimmer is powered by electricity. So it could be corded that needs to be plugged in a socket. Or cordless where it’s battery powered.
It has a long shaft with a handle on one end and a cutting head on the other. The string trimmer uses a monofilament line instead of a blade for doing the cutting. The line will rotate fast and this rotation helps to cut the plants.
What are the different types of string trimmers?
You can get a string trimmer that is powered by electric or gas. The electric one could be corded or cordless.
The gas powered ones are great if you want good cutting power. And they are quite mobile because you just need to fill the tank up and you’re good for a long period of trimming.
The problem with a gas-powered string trimmer is the noise they produce. They need a lot more maintenance and they’re a heck of a lot expensive.
The future is electric and the same holds for the string trimmer. You can get an electric one that would be as good as a gas powered one.
They have the benefit of less noise so you won’t damage your ears and your neighbor’s. They’re a lot less expensive than a gas string trimmer. And they need less maintenance than the gas powered ones.
You can get electric string trimmers that are corded. So you plug them into a socket and you’re good to go. Though this means they are limited in how far you can work with them.
The other electric option is a cordless string trimmer that runs on battery power. This makes it more mobile when working outdoors. But it’s a little bit more expensive than the corded one.
Do you need an electric string trimmer?
If you have a garden, you’re going to face the problem of weeds, uneven growth of grass and plants. So you’ll need some sort of trimming tool.
If you have a small garden, a garden shear should be enough to get the job done. But if you’re working with a large garden, it’s good to opt for a good electric string trimmer.
It can help you reach places where a shear or a lawn mower cannot. It’ll help you cut grass in hard-to-reach places like around fences, trees, and walkways. And it’ll help you edge the garden bed and bring it in shape.
It’s beneficial for you if you have back issues and cannot be bending in the garden for long periods of time.
How to choose a good electric string trimmer?
There are certain features to look out for when you’re choosing an electric string trimmer to get the best value.
The first thing you’ll notice about string trimmers is the shaft that connects the handle to the cutting head.
This shaft could be curved or straight in design. The straight ones are best for tall users while the curved ones are better for shorter users. Because you need to trim at an angle that’s most comfortable based on your height.
You can choose between a corded and cordless string trimmer.
The corded ones are inexpensive and lightweight but they have limited mobility because they’re limited by the length of the power cord. The cordless ones are battery powered and have great mobility outdoors but they can be more expensive.
Depending on the power source of the electric string trimmer you choose, you’ll need to check the power capacity.
This could be in Amperes for the corded ones and Volts for the cordless ones. The more power you need the higher these values should be. But the price will be based on this as well.
For the cordless ones, remember to check the battery capacity. You don’t want your trimming work to stop because the battery died too soon. Choose one that comes with good battery capacity.
For the corded ones, it’s good to buy an outdoor extension cord that is long enough that you can trim comfortably in the yard.
The cutting head is the thing you’ll find at one end of the electric string trimmer.
Make sure that the area between the shaft and the trimmer has a small gap. If there’s a large one, long grass and weeds will get stuck there while trimming. Check that it’s easy to clean the head in case you want to remove debris from it.
The RPM (Revolutions Per Minute) tells you how fast the string trimmer head can rotate. The faster it rotates the better it will cut.
The string is attached to the trimmer cutting head and is the part that does the cutting work. You want to make sure it’s the best quality that doesn’t break or get worn out fast.
Some string trimmers may have two lines that can help you cut heavier growth with ease.
They might have a spool or fixed-line type of string attachment. The fixed-line helps reduce jams but needs faster replacement.
It’s good if your string trimmer has an automatic feed spool so you don’t need to stop work and add more string. String trimmers come with a bump feed where you need to bump the cutting head on the ground and it automatically brings out more string.
Choose a handle that is ergonomic and has a soft grip. This is especially useful if you’re going to be using the electric string trimmer often.
Some string trimmers come with an adjustable handle that can be pivoted as well as adjusted for length.
This is another important factor if you’re going to use the electric string trimmer often. You want it to be lightweight enough to carry around the yard without fatigue.
It’s best to choose a string trimmer that has good balance as well. The ones with the motor on one end and the cutting head on the other give the best balance.
The handle of electric string trimmers might be fixed. Or you might get some that can be pivoted as well as extended. So choose one based on your needs.
Some string trimmers come with controls that help regulate the speed of the cutting head.
We always recommend going for the best quality tools and this holds for the electric string trimmer as well. You don’t want your trimmer to die on you after a few weeks of use.
Choose one that comes with the best quality and durability. The price that you pay will be worth it.
The price of your electric string trimmer depends on several factors we’ve already seen. The cordless ones may cost a bit more than the corded ones.
If you need one with a larger battery or more power, it’ll cost you a bit more. Quality and durability might also be factors to consider the price.
You want to make sure to get the longest warranty as possible. If you’re chosen a good quality electric string trimmer, you’ll not have problems. But it’s better to be safe than sorry in case something goes wrong.
Precautions when using an electric string trimmer
Make sure that you’re not using the electric string trimmer in bad weather. You don’t want to get electrified when working in rain or when the garden is damp.
Inspect the electric string trimmer and check if there is any damage. Make sure the parts are all fixed and not wobbly.
Make sure to clean the trimming head from any debris that might be stuck in it. The string in the head will keep shortening over time. So ensure that the string is in working condition before using the trimmer or replace it if required.
Wear a pair of thick, long pants, covered shoes, and gloves that can protect your feet and hands from any accidents. A good pair of safety goggles can help protect your eyes from debris flying during the trimming.
How to use an electric string trimmer
The electric string trimmer is a great tool to trim around fences, trees, and ppes where a lawn mower can’t reach.
When you’re trimming the grass, you want to keep the trimming head level and parallel to the ground.
Trim the grass to the same height as you would with a lawn mower. This will help keep the cutting even on your entire lawn when you use both.
The trimming head rotates in an anti-clockwise direction so you want to make sure to trim in a direction so that the trimmings fall onto the lawn. Later when you mow the lawn, it will include these trimmings as well and you don’t need to do extra work collecting them.
When you want to edge the garden beds or pathways, pivot the trimming head at an angle so it’s possible to do so.
In case the string shortens during the trimming, you can bump the trimming head on a flat surface and it should advance the line.
You could even use the string trimmer to blow any trimmings from the pathways onto the lawn. Just use it in a sweeping motion over the pathways to move the trimmings.
Maintaining your electric string trimmer
If you’re using a corded string trimmer, check if there’s any damage to the cord. If it does you’ll need to get it replaced. Check the same for the outdoor extension cord you’re using. If there’s any damage, get a new one.
Check that the string trimmer is clean and does not have moisture, oil, or grease covering its surface.
Before trying to use the electric string trimmer, take a look for any damage. It’s dangerous to use a damaged trimmer so either get it fixed or replaced.
The trimming line or string in the trimmer may have become brittle and weak. So check if it needs a replacement.
You can store the electric string trimmer in a dry location and at a height that’s safe from the reach of children and pets.
