Cordless String Trimmer Features
When searching for a cordless string trimmer, you need to consider some general features before making a decision. There are many types of string trimmers available including cordless, electric and gas-powered. It is important to make sure that the string trimmer you choose is cordless. They are lighter, easier to maintain and do not require fuel to run. Below are some other guidelines to follow.
Battery Power
Most cordless trimmers use lithium ion batteries for power. Batteries rated from 40V to 80V will provide more power than their lower voltage counterparts. If you have a small yard, a 20V battery powered trimmer will be enough for you. Larger yards will require a higher voltage power for you to complete your trimming all at once.
Consider the size of your yard and the voltage of the trimmer before making a choice.
Trim Area Diameter
Trimmers can cut a path anywhere from 10-inches in diameter up to 14-inches and more. If you have a lot of tight spaces in your yard that need trimmed, you may want to consider a trimmer that has a smaller cutting swath.
Adjustable Handle and Height
Will you have several people who will use the cordless trimmer? Then you want one that has a multi-position handle. An adjustable telescopic height adjustment feature is equally important This allows everyone to adjust the trimmer based on their ergonomic comfort and height needs.
Safety Shields
Safety shields are important for any yard tool. Make sure the trimmer you are considering has safety shields in place to protect you from flying debris while you are trimming your yard.
Trimmer Line Feed
There are 3 different types of trimmer line feed:
- Bump feed – With a bump feed trimmer, you literally bump the trimmer on the ground in order to force the line to advance.
- Button controlled – Some trimmers have a button you can press that will advance the line in a semi-automatic manner.
- Automatic – There are some manufacturers who have discovered how to advance the line automatically based on patented technology.
The bump feed is the oldest and most reliable method. If you want to try something new, then look for a trimmer that has an automatic or semi-automatic line feed feature.
Conclusion
There are many features to consider when searching for a cordless string trimmer for your yard. With so many trimmers available, you do not need to be overwhelmed by the choices. The guidelines above and the reviews of our top 10 favorites should give you all the information you need to make an informed decision.
