Buyer’s Guide for String Trimmer
The best and perfect trimmer can only be chosen when you are well-aware of the features that make a string trimmer a better tool. Below are the features that you must check out in your weed whacker before you draw out a decision.
The trim width determines the width of the lawn you can trim in one go. So, it also determines the time you need to achieve the end step of your lawn session. Usually, the battery-powered trimmers are equipped with 12 inches of trim width. This is the standard width of the trimmers and can give satisfactory performance for small lawns.
But if you have a high volume of grass to trim off, a 15 inches string trimmer will be a better choice for you.
When you want to find a string trimmer just to weed off the thin volume of unwanted straps of grass around your lawn’s perimeter, a medium powered motor will do. But that is not the case for trimming thick areas. Higher the workload, the more powerful should be the motor.
When you need to deal with a land crowded with grasses, a higher voltage motor engine will be a suitable selection.
‘Ah’ of the Battery
How long the trimmer will run before you need to have a plugin is determined by the “Ah” of the battery. It also depends on the level of toughness of the job you employ your trimmer for. If you need to cut off a few extras here and there by just pulling and releasing the trigger, the charge lasts long. However, when you need to run through a ground of tall and thick weeds, the battery can wear off faster.
So, a professional lawing team that trims large areas of land for hours after-hours needs a higher battery capacity with backups batteries.
The more you trim, the faster the string gets wear off. After losing its sharpness, the line may break and needs to be reloaded, which interrupts the trimming. So, to stop the adding of extra time for changing lines, you need a string of thicker diameter.
The line diameter of the standard string trimmer is 0.080 inches is sufficient for residential yards while the professionals need something more than 0.095 inches.
It is prevalent for the professional to own separate machines for the process of string trimming, to edge, and hedge trimming. But for the homeowners with small lawn to take care of, the budget can be sky-high.
The feature of attaching heads and tools interchangeably, starting from blowing to brush cutting, can save a lot of money.
The most significant benefit of a string trimmer equipped with lithium-ion batteries is its potential to operate with less noise. This feature is more demanded by the owners who have to live within noise limitations.
Balancing can be a real factor in having a smooth and effortless trimming throughout the lawn.
Pushing a heavy trimmer makes you hold an awkward body posture throughout the session and can leave you with pain.
Most of the battery-powered string trimmers have an excellent balancing with the motor on the top of the tool. But few come with the engine placed above the shaft link, making it a little off-balanced.
The factor that most important affects the ease movement of a string trimmer is its weight. Even with the fastest speed and powerful motor, trimming a ¼ acre lawn cleanly takes 15 to 20 minutes. Drawing and pushing a heavy trimmer can suck all your energy.
So, while choosing a trimmer, you must go for the lightest weight model you can search for without compromising the quality of the motor.
Additional Feature: 90-degree Head Tilt
Most of the time, during trimming, it’s becoming challenging to reach places like under the deck of the house or close perimeters of the trees. The problem can be reduced with a trimmer offering a 90-degree head tilt.
In our list, we have WORX WG163, which offers the innovative feature of a 90-degree head tilt. It assists you in giving a clean trim even to those parts of the lawns, which is harder to reach or have tight spacing.
