Our Pick

Husqvarna 128LD 17-Inch Straight Shaft Detachable String Trimmer, 28cc

Our top pick for the best weed wacker

The Husqvarna Straight Shaft String Trimmer is our best string trimmer that is currently found in the market. This gas-powered string trimmer allows you to enjoy the amazing power outputs of gas engines. The 28cc engine produces about 1 HP which is quite decent for trimming.

A Smart Start System makes starting the engine very easy. Even I hate the endless cord pulling when starting the gas engine. But with this, this task is made a breeze. The tough standard 0.095” trimmer line tackles any types of weeds real head on.

With such amazing weed eating capabilities, you may think it weighs a tone. But it weighs quite the opposite, weighing a mere 11 pounds. Even a hard to impress me is wowed by that for this best gas weed eater.

How to choose the best string trimmer

The consumer market of weed eaters is flooded with different options that you can choose from. What this does is make it a little hard for you to decide on the one that best suits your needs. In this section, I have the intention of showing you how to separate the wheat from the chaff.

  1. Types of Weed Eaters

When setting out to buy the best weed eater, this is the first decision that you will have to make. And when deciding, the size of your lawn will come into play as well as the frequency with which you will be using the trimmer.

Generally, there are three types of weed eaters: Gas powered weed eaters, Corded and Cordless (battery) string trimmers.

  • Gas trimmers

If your lawn is considerably large, has tall grass and weed or the weed is tough, then a gas-powered string trimmer will be the best choice for you. They may be a little heavy, but this is compensated for by the power they deliver.

What bothers me most is the high noise levels and considerable fumes they produce. However, with newer designs, the noise levels have been greatly reduced, as does the fumes produced. What is better is that some can even use steel brush cutters for thick brushes in your lawn.

  • Corded Trimmers

But if your lawn is small, has a couple of weeds or the weeds and grass is the soft type, then an electric weed wacker should do for you. These types are the lightest, cheapest and basically meant for those occasional lawn grooming needs.

If you have a reliable power source, and don’t mind dragging along power cords, then these could be a good choice.

  • Cordless String Trimmers (Battery Powered)

Cordless weed eaters eliminate the annoying cords, do not produce any fumes and are very portable. They are a good option if your lawn is slightly too large for power cords, but have soft weeds. This is since they are generally less powerful.

Their drawback is the battery life. It will run out of power at some point, meaning you will have to stop, recharge it, then continue with your work.

When looking for one, the battery life should be a top consideration. You should ideally look for the models with lithium-ion batteries as these last longer in a single charge.

  1. Design ergonomics

The best weed wacker should feel comfortable when being used. This is more so if you are going to use the whacker for a considerable amount of time. There should be some sense of balance in the whacker when being held in your hands, with a uniform distribution throughout the length.

Vibration damping is another key aspect you will have to consider. Eliminating vibrations altogether is impossible, but damping it is important in ensuring less fatigue when using the weed wacker. The electric weed eaters will not have this problem, but the gas-powered counterparts will definitely have this problem.

Lightweight electric models only have a handle mounted at the top for a firmer control over the machine. In contrast, the heavier gas-powered types should have an extra shoulder harness for longer periods of use.

  1. The string feed options

The ease with which a new line is fed will vary from trimmer to trimmer. How a new line is fed is also different and will determine how easy and convenient it is to use the tool.

Here, you will have three choices: Bump feed, Fixed Lined feed and Auto Feed.

  • Bump feed

The bump feed requires that you bump the head of the trimmer onto the ground. This then activates the mechanism that feeds a new line.

  • Auto feed

An Auto feed mechanism feeds a new line once the existing one wears out. This allows you to concentrate on eating the weeds away.

  • Fixed line feed

For a fixed line feed, a certain length of the line is loaded onto the trimmer. Once this is exhausted, you then have to reload another fresh line manually.

  1. Performance ratings

This feature is very critical if you want to end up with the best weed wacker. This is the description of the amount of power the engine generates, the length of the cutting swath and generally what makes the weed eater tick.

Depending on the size and nature of your lawn, you will need different engine power outputs to tackle these conditions. Tough grass will need to be whacked with the most powerful engine within your budget.

And the higher the engine displacement (indicated in cc), then the more power the engine delivers. A longer cutting swath will also be necessary for a faster rate of job completion. And then to access those hard to reach spots, you would need a longer shaft, if not a telescopic one.

  1. Curved vs straight shaft

The power that is delivered by the engine is transmitted to the cutting line through the shaft. These shafts can be found in the two options: Straight and curved.

  • Straight shaft

The straight shafts are great for reaching hard to reach spots and work well for users who are tall.

  • Curved shaft

The curved shafts, on the other hand, are much lighter and are much easier to handle than the straight shaft ones.

  1. Other features

Features such as a rotating head will be useful when you want to edge your lawns after mowing or trimming them. This eliminates the expense of another tool for the same job.

Starting and stopping aids make operating a gas-powered trimmer much easier. A spring assisted starting feature will be very useful.

  1. Husqvarna Straight Shaft String Trimmer

Husqvarna 128LD 17-Inch Straight Shaft Detachable String Trimmer, 28cc

With a 28 cc, 2-stroke engine powering it, the Husqvarna delivers enough power to be used by professionals and DIY enthusiasts alike. It has features that make using it quite a breeze. For starters, it uses a Smart Start System which aids in getting it up and running. You don’t have to struggle with endless cord pulling.

Secondly, a semi-automatic line feed system keeps the weed wacker running in top condition throughout. Once the standard 0.095” trimmer line wears out, a new extension is automatically fed through. And if your lawn has tough shrubs, there is a steel brush that you can fit in the head and power through the tough shrubs.

Since it is a gas-powered trimmer, the motor needs the gas to be mixed with oil to run properly. This may be inconvenient, but the raw power delivered after that will be worth it. This gas trimmer weighs just 11 pounds. Such weight will not wear you down much as you work.

  • Works great
  • High quality
  • Semi-automatic feed
  • Easy to start
