Types of String Trimmer

There are basically three main types of string trimmers on the market, each with its own defining features. The different types and their features are as follows.

1. Corded Electric String Trimmer

These string trimmers are powered by electricity and come in a cordless or corded model. It’s very convenient and more comfortable to use.

Also, the use of electricity means it’s eco-friendly. But electric weed eaters have typically less power than gas-powered weed whackers.

The corded electric string trimmer uses an electrical cable attached to the weed eater to power the motor. It’s useful as you don’t have to worry about charging or replacing batteries or fill up the gas.

It’s ideal to use in a small to medium size garden as you’re limited by the length of the cable. You can use extension cable in some situations, but it may become a hassle if you got several plants or bushes in the garden.

You may also have to keep unwinding your cable as you cut weed around the trees and bushes.

2. Battery Powered String Trimmer

This type of string trimmers are gaining popularity as it’s very convenient to use, weigh less than gas-powered trimmer, and are eco-friendly.

It’s ideal to use for any garden size as you’re not limited to how far you can move around, unlike corded electric weed eaters.

The battery also allows you to use it quickly for smaller jobs, such as cutting a small portion of lawn where you find new weed growth.

The only downside with a battery-powered string trimmer is that you have to keep it charged. It’s always a good practice to connect the battery with a charger after each use. It will avoid the battery dying off in the middle of the job.

String trimmers like this are more economical to operate than other types of string trimmer.

3. Gas-Powered String Trimmer

Gas-powered string trimmers are primarily targeted toward professional landscapers or people with a big backyard. It’s more powerful than the electric-powered string trimmer and allows you to cut thick and stronger weeds.

Here, the only downside is to keep it filled up with gas, and it generates lots of smoke. The gas engine is also noisier than the silent electric motor.

Plus, it’s heavier than the other string trimmer as these types of string trimmer have a small internal combustion engine. And you have to carry it around with a gas in it which adds extra weight.

If you decide to use a gas-powered string trimmer, then we recommend getting the model which has a transparent fuel tank. It helps you see the amount of fuel left in the tank.

Things to Look for in an Electric Weed Eater

There are some important features you need to keep in mind before purchasing. These will allow you to choose the best model and get your money’s worth.

Battery And Power

Regardless of whether you use a corded or cordless string trimmer, the primary power source in these types of weed eater is electricity. The electric current moves the trimmer motor inside. And the more powerful the engine, the more electricity it will consume.

This is where the power rating of the electric string trimmer comes in. The corded electric string trimmer plugin to standard 120 Volts with varying current levels depending on the power of the motor.

Choose a corded electric string trimmer when you need more power to remove more robust grass or weed. As we said earlier, choose it if you have a small to mid-size garden with not much obstruction to move the cable around.

Pick a cordless electric string trimmer if you don’t have tougher weeds or grass in the garden. The main benefit of a cordless string trimmer is increased mobility. You can move anywhere without getting restricted by the length of the cable.

Battery Charge Time

The battery charge time varies depending on the power rating and the battery type. Some batteries get fully charged in a few hours, and some take several hours to get charged.

Look for the batteries and the charger type if you need something which does not take too long to get fully charged.

Tip: The power of the electric motor is denoted in the Ampere (Amp). Most electric string trimmer comes in a range of 1 ampere to over 10 amperes. Higher the ampere means more powerful the string trimmer.

Moreover, for small yards, 1 amp to 4-amp rating will be enough. For large yards, pick anything more than a 5-amp rating.

String Trimmer Layout

The design and layout of the string trimmer are essential as you will be carrying it around with you for an extended period. A poorly designed string trimmer will make you get tired quickly, or it may be awkward for you to handle it.

Pay close attention to the motor position, the overall weight, and the length of the shaft. These are essential design factors that will make trimming a painful or pleasant experience.

Furthermore, the smooth and well-placed controls make it easier to operate the trimmer. The shaft of the trimmer connects the main motor to the feeder. There are two common design types of the shaft; straight shaft and curved shaft.

Now, the straight shaft is more convenient if you’re tall and need some distance between the holding handle and the ground. The curved shaft is lightweight and more comfortable to use around hard-to-reach places such as under the bush.

Find out which type of shaft design is more comfortable for you. Most trimmer models also allow you to adjust the shaft length.

String Trimmer Line

The line of a trimmer is made from nylon or a polymer string. And the trimmer line should be of good quality, so it doesn’t break when in use. There are two main types of trimmer lines available, the consumer-grade trimmer line and the commercial-grade trimmer line.

Moreover, the consumer-grade trimmer line is cheap and is suitable for small to the mid-size yard. The commercial-grade trimmer line uses high-quality, durable materials. It’s ideal to use if you’re a professional landscaper or have a big yard and tough weeds to remove.

It’s very common for these string trimmer line to break during the use regardless of how strong it’s. Keep some spare trimmer line just in case you need it while trimming your garden.

Shoulder Strap (Optional)

If you’re trimming a small yard or garden, then you may not need to carry it around for a long. But if you’re doing anything which requires you to hold a string trimmer for some time, then look for the shoulder straps.

Most electric string trimmers are lightweight, and you may not need one. But if you’re getting a heavy-duty and more powerful electric string trimmer, then it may be wise to pick a model which has a shoulder strap as it may get heavy.

The shoulder strap makes it easier to hold the trimmer, move it around to trim, and prevents you from getting backache.

Weight

As you may have imagined, weight is an essential consideration when looking for a string trimmer. Fortunately, the electric string trimmer is far lighter than the gas-powered string trimmer.

But check out the weight of the trimmer before you buy as it all depends on your comfort level to carry.

Ease of Use

The electric string trimmer is easier to use. The use of electricity means, there is no long waiting time or hassle of filling up a gas tank.

When you need to trim, simply attach the battery or plug it into the power outlet. Look for the length of the cord and layout of your yard when using a corded electric string trimmer.

If you have lots of plants and bushes, then it may not be convenient to use a corded string trimmer.

Trimmer Line Cutting Diameter

The cutting diameter of the lawn depends on the trimmer line length and the cutting feeder area. Pick a string trimmer depending on the size of your garden and the type of weed or grass you want to cut.

And for any small to medium size garden, choose a trimmer line which provides 10-15 inch of cutting diameter. For a large garden or when you have thick weeds or grass, choose a 15 to 18 inches cutting width.

Most of the gas-powered weed eaters have more full cutting diameter than the electric string trimmers.

String Trimmer Line-Feed

This allows you to trim the weed without getting any interruption. Some models have a manual line-feed where you have to turn-off the trimmer to change or unwind the line from the spool.

The bump head in the string trimmers automatically feeds the trimmer line with a simple tap on the ground. It reduces the time to trim as you won’t be stopping and changing the feed line.

Some trimmer line also has automatic line-feed (AFS) which releases the trimmer line when it gets too short.

Safety Considerations When Using a String Trimmer

There are certain safety factors as well that you must take under consideration when using a string trimmer. These factors will keep you and your device safe from imminent damage.

Noise Level

The electric string trimmer is less noisy than the gas-powered one. But you still get the noise from the motor and the noise from the string shaft.

Always wear protective noise cancellation headphones to prevent damage to your hearing ability. As the continuous long-term exposure affects the hearing ability, it’s better to put on earmuffs.

Plus, you don’t want to annoy your neighbor with noisy garden maintenance.

Protective Measures

The string trimmer feeder spins at a very high rate, which may become a safety issue.

Choose a string trimmer with a straight shaft as it allows you to maintain a reasonable distance between the weed and you. Also, the placement of an emergency cut-off switch is a nice safety feature if something goes off.

Accessories

Some string trimmer comes with an option to change the cutting line and spools. Additional attachments which you can use are brush-cutting blades or wider edging heads.
