What is String Trimmers? – Its Uses, Benefits, and Drawbacks

What is String Trimmers

Like the Brushcutter, a string is also a tool that is used to trim grasses around the yard.

However, a string trimmer is not for cutting thick weed stems or tree trunks. You can cut only the small and easy to cut grasses and weeds using this tool.

Instead of using a metal blade, a string trimmer uses a monofilament/nylon line to do the operation.

It’s more lightweight compared to the brush trimmer and also costs way less. Nonetheless, the nylon is not as durable as the metal blade of a brush cutter.

A string can be of three types – gas-powered, battery-powered, and electric corded.

If you want to clean a large surface, then a gas-powered string trimmer is the best bet for you.

On the other hand, if you want to clean a smaller surface, then a battery-powered string trimmer is enough to serve the purpose.

An electric corded string trimmer allows an even more specific surface.

So, let’s sum up the benefits of a string trimmer.

Benefits of String Trimmers

  • It’s lightweight and easy to operate. That’s why a beginner or any DIYer can start using it comfortably.
  • A string trimmer costs pretty less compared to a brush cutter.
  • It can reach to a tight space.
  • You have the liberty to choose from different types of a string trimmer (gas, cordless, corded) based on your budget and needs.
  • Some string trimmers offer full rotation features that make it work as a lawn edger. That means where the weed mowers can’t reach; you can use a string trimmer as an alternative.

Brush Cutter Vs String Trimmer – Which One is the Best?

While both of these tools do the cutting and trimmer, you saw some differences, if you read through the last couple of points.

It’s not that hard to tell which one is the best, but it depends on your application and budget.

Yes, both of these tools save money from spending a somewhat significant amount on hiring professionals to clean up the lawn.

However, a brush cutter costs more than $100; a good one requires even more like $200. Whereas, an electric string trimmer costs around $30.

So, if you want to go for the budget solution, then perhaps string trimmers are the ones you should be looking for.

With that said, as you saw, the application of both of these tools is not the same.

If you have to cut tree trunks up to 4” thick or thick weed stems, then you must go for a brush cutter.

On the other hand, if you have to deal with only small grass and weeds, then no need to spend money on a brush cutter. Better go for a string trimmer.

So, which one is the best? It depends on the application first, then the budget.
