What Is A String Trimmer?

A string trimmer is a tool that uses a flexible monofilament line to cut grass and plants near objects. String trimmers can even work on rough or uneven terrain making them useful landscaping. It has a cutting tip located at the end of the shaft with a long handle.

String trimmers work on the physics principle that a line can become stiff once rotated at a high velocity. The higher the velocity, the stiffer the line. Some string trimmers have monofilament lines that have an extruded, start-like shape. This makes it easier for the line to cut through the material such as small shrubs effectively.

What is a string trimmer

String trimmers are used to cut through places that your lawn mower can't reach. They are perfect if you're planning to cut down weeds, brush, or grass on steeper inclines. Also, string trimmers are used to trim or edge yards to enhance their appearance.

With its long handle, whirling string, and compact weight, a string trimmer is essential for your daily yard maintenance. You can trim away weeds and grass against a fence, underneath the shaggy boughs, and up to the tree trunks. Overall, string trimmers give your yard or lawn a nice finished touch.


String trimmers come in two different types: Gas and Electric.

Gas Powered

Gas powered string trimmers have more power and are usually cordless. For heavy duty jobs where you have to cut through a lot of material, gas powered trimmers are the way to go.

Gas string trimmers with 2-stroke engines require a mix of oil and gas to operate. Some models with 4-stroke engines are smoother to operate, faster to start up and don't require oil/gas mixtures. Gas powered trimmers have pull starters- you might have issues starting the engine sometimes.

Gas String Trimmer

Gas trimmers weigh more and have a higher noise level than electric powered trimmers. Gas trimmers will require more maintenance than electric trimmers due to their inbuilt motors.


Electric trimmer models can be either cordless or corded and are ideal for simple yard jobs. If you have a small garden, electric trimmers are a better investment than their gas-powered counterparts. Electric trimmers are powered via rechargeable batteries (NiCad or Lithium-Ion).

Electric Powered Trimmer

Cordless electric units have quiet operations, extra mobility, and faster start times, and weigh less than gas-powered trimmers.

Corded electric trimmer models operate quietly, easier to start, and are lighter than cordless models. Both corded and cordless electric trimmers require little maintenance. Whichever type you choose depends on the size of your lawn, the location of power outlets, and how frequent you trim.

How To Use A String Trimmer

Here are a few tips to help you use your string trimmer effectively:

Understand The Trimmer You're Using

First, depending on your choice, different trimmers are suited for different people and situations. Some people find Straight Shaft Tools to be easier to control and effective since you can move them under shrubs and small trees. Others tend to use Curved-Shaft String Trimmers when you need to cut your grass at a specific angle.

Understanding Spinning Direction

Next, understanding the spinning direction is another needed technique that you must know. Most beginners struggle with spin direction when using their first string trimmer. It's simple as ejecting saw dust and circular saw cutting. In that way, your trimmer should eject debris and material from its path when using it.

Counter clockwise spin directions remove debris from the left and cuts gas through the right side. This means that if your movement is along a curb or low fence, keep the right side of the trimmer close to the area you're working on.

Wire Trim Spin

Cutting in the opposite direction means debris or material ejection into the cut path, trimmer bogging, and scalping (too much cutting of the grass blades).

Cutting Techniques

The third and final technique involves cutting. For your trimmer to create the desired cutting results, understand that the string ends have the most cutting power. The faster the string ends spin, the harder they will cut the material and the better the results.

Edging, Tapering, and Screeding, and Scything are the cutting techniques that you need to take into consideration.


Edging is used for parallel surfaces. For example, driveways, walkways, and in between grass. The string trimmer is turned so that the string is in a vertical position; making it easier to remove debris from the desired cut path.

When edging yards that haven't been properly edged for a long time, expect to pull up dirt, rocks, and other forms of debris. After all of these, the maintenance is easier and takes less time than usual.

Line Trimming The Edge

If the trimmer is not held in a way that the surface is parallel to the string, the string diameter will just cut at a full grass swath. A sign that it did not taper is when the cut grass is shorter when compared to the mowing grass.

Consequently, when your trimmer string tips are placed towards the desired object to be trimmed, a lesser amount of grass is cut which results in a tapered edge. Thus, blending the edge with the mowed grass height to make a pristine look.


Screeding is effective on grass and weeds that grow in sideways, paths, and sidewalk cracks. Your weed eater is tipped in a way that the strings slightly glance the pavement. Then move the string tiller to the weed's base and cut it.

When screeding your garden, you need to be careful. Because if your trimmer at a shallow angle, it won't cut but eat the string. If the angle is too sharp, then it won't be able to cut through the weed base effectively.


Tapering, just like edging is used for edge treatment along the walls, curb, fence line, or even the tree. The method requires you to hold your string trimmer in a way that the string strikes the grass at a slight angle.

Lawn Care Tapering


When scything, your string trimmer should be brought in and out of work. This needs to be done in a shallow U-turn method. Doing this overlaps the scythe and makes an even cut. We suggest using this cutting method when you need to trim weeds quickly and efficiently.

What To Look For In A String Trimmer

Before you buy, it's best that you understand the specs. Once you've got a good grasp on what each spec does for your trimmer, it's time to make a purchasing decision. Choose the trimmer whose specs suits your and your garden's needs.


Do you need a gas-powered or an electric trimmer? Here is a table discussion the pros and cons of each string trimmer type:

Trimmer Type





  • Light weight
  • Easier startup
  • Consistent power and unlimited run time
  • Little maintenance needed
  • Eco-friendly, no fumes, oil, or gas
  • Low mobility – Coverage is limited by the cord’s length
  • Power cord can be a distraction



  • Cord free and doesn’t need gas
  • Low maintenance
  • Quiet operation
  • Lower weight than gas
  • Replacement batteries are expensive
  • Heavier than corded electric trimmers


  • Ample power
  • Dual trimmer heads cut faster
  • Accepts a wide range of attachments
  • Ideal for intensive cutting
  • Uses lines with larger diameters
  • Loud operation
  • Not environmentally friendly
  • More weight than electric models
  • Higher operating expenses due to oil and gas costs
  • Tends to use pull starters


In addition to the features of your trimmers, weight is another option that you need to consider. While stronger trimmers can handle tougher weeds and larger areas, they tend to be heavier than lighter string trimmers. Invest in a gas powered string trimmer if you want something that's heavy that delivers a lot more power than electric models.

Consider the trimming jobs and look for a trimmer with a balance between weight and power to comfortably handle them.

Match The String Trimmer To Your Yard

As a rule of thumb, the larger the landscape, the stronger your trimmer will be to maintain it. Stronger trimmers can handle a large variety of tasks.

Light-Duty string trimmers can handle light grass and some weeds. They're used for landscapes that are about an acre in size.

Medium Duty string trimmers work thick weeds and grass. Some units allow you to use attachments for other jobs. They're best for a few yards up to an acre but are also effective for yards that are 2 acres in size.

String for every ocasion

Heavy Duty string trimmers are good for tougher weeds and grass and can accept a variety of attachments. These trimmers work on yards that are 2 acres but can be used for larger landscapes if needed.

Professional string trimmers can cut through almost any weeds, grass and use power attachments to handle other jobs. They work the best in every landscape size and should be considered if you're serious about keeping your garden perfectly clean.

Noise Levels

On average, electric string trimmers operate at a sound of 85 decibels. In comparison to gas powered trimmers, they are quieter and operate faster. Gas string trimmers release their sound within a range of 90-105 decibels.

Remember, using string trimmers can be very loud. If possible, invest in a pair of sound reducing ear equipment. Doing this allows you to operate effectively without allowing the sound of the trimmer to damage your ears.

Safety Features

Like lawn mowers, string trimmers require a lot of awareness and concentration to operate. They are dangerous power tools and can result in serious injury if not used correctly. To trim safely, you should invest in a protective shield guard for your trimmer.

Safety Features

The protective guard for your trimmer should be made in a way to protect you and the machine from flying debris. Even with the best, most high-end shield, you'll want to wear a pair of safety goggles, long pants and sleeves, and shoes to prevent getting injured from the flying debris.

Does your trimmer have a trigger lock? You should buy an electric trimmer with this feature to stop the trim head from starting accidentally. Your trigger lock switch should be stored in a safe location where it can be easily accessed.
