Once you've mowed the lawn, your work is not over—you still have to get out your string trimmer to finish the job. String trimmers are great for:

  • Tidying grassy areas around gardens, trees, fences, or other obstacles, such as swing sets or decking.
  • Going into overgrown areas of brush that are more than a mower can cope with.

Generally speaking, when it comes to buying a trimmer, the more you pay, the better quality model you get. A cheap string trimmer may seem like a bargain at the time, but may give out after a few seasons; whereas a more expensive and higher quality model will last a long, long time, as well as often having other advantages.

String trimmers are sometimes called weed eaters, or weed wackers. They work through a revolving cutting head that automatically feeds a cord (or string) from a spool, as the spin creates a centrifugal force.

Before I give my suggestions for string trimmers, I think it is important to understand the different styles of trimmer out there, because each is designed for a different purpose.

3 Types of String Trimmer Used in Yardwork

Trimmers come in several styles: electric trimmers, gas-powered trimmers, and brush cutters. It is very important that you pick the right type for your needs. To pick the correct style, you first need to consider: the type of material that you are whacking; the size of the area you are working on; and whether you require any restrictions regarding noise.

  • Electric string trimmers are quiet and convenient, plus you don't have the hassle of dealing with gas and oil. They are powered either by an extension cord, or a battery pack. Easy to use, they are light and maneuverable and great for small to medium-sized spaces.
  • Gas-powered string trimmers are suitable for large lawns and heavy trimming use. Powerful and versatile, these trimmers come with 2-cycle or 4-cycle engines. Used by landscaping professionals, some models also come with attachments for edging, pruning, and cultivation duties, as well as trimming.
  • Brush cutters are the big boys of the trimmer world, they have larger engines, thicker line, and strong metal blades for dealing with dense brush and weeds. As well as handheld versions, you can also purchase walk-behind and tow-behind versions for clearing big areas.

String Trimmer Safety Tips

  • Before you get started, make sure that you are completely familiar with your machine, including its safety features, and that it is the appropriate style of trimmer for the job (see above).
  • Wear protective gear. Eye protection, gloves, long pants, long sleeves, and closed toe shoes all help to protect you from flying debris and toxic plant material.
  • It is important to know which direction the strings in your trimmer are spinning, as this affects where the debris is thrown out. If the strings rotate counter clockwise, that means that it cuts to the right and and debris will be expelled from the left side of the trimmer. If the strings rotate clockwise, the debris will come out to the right side. Always try to keep your body towards the cutting side.

String Trimmer Basics

Using Your String Trimmer

You would think that using a trimmer would be easy, you just hover over the area of grass that you want to cut and let it do the work, but this is rarely the best method and can result in scalping.

The truth is that there are numerous more effective techniques for using a string trimmer, some of which are explained below.

  • Edging: To deliver a clean, crisp borderline between the grass and driveways and walkways, you can turn your trimmer so that the strings rotate vertically. You should then walk the into the cut path, allowing the debris to be thrown into the are that has just been cut. It may take several attempts over time to create a crisp edge.
  • Tapering: This can be very effective for dealing with borders where the grass grows along trees, decks or fences, or when the border is on a bend. It is a pleasant and practical alternative to edging in many circumstances. Tapering is achieved by simply holding the trimmer at a slight angle, pitching it slightly towards the fence or object that you're trimming against. Done well, the taper will blend with the mowed grass.
  • Trimming: As mentioned above, the most obvious method for using your string trimmer can also do the most damage to your trimmer if not performed correctly. When cutting tall grass, start by trimming from the top down to stop the string from getting tangled. When dealing with bigger trimming jobs, start trimming in small sections rather than attempting everything at once. This should stop the trimmer stalling and prevent the string from tangling.
