Factors to Consider When Choosing the Best Gas String Trimmer

1. Types of Gas Weed Eaters

There are three main types; gas, electric, and battery-powered.

  • Gas Weed Eater

These models are the most durable, portable, and powerful products. They feature strong combustion engines that are enough to get you through the thickest brushes and weeds. Plus, you won't have to worry about restrictive movement since they are cordless.

As a result, you can carry them as far as necessary to clear out unwanted vegetation. The main drawback of this type of weed eater is their noise since they are quite loud and challenging to start.

  • Electric Weed Eaters

In contrast to the gas weed eaters, the electric models are far quieter and can start up much faster without any trouble. All you need to do is to plug them into a power source and press the trigger. Unfortunately, the extension cord on these weed eaters will limit your mobility. They also have less power and are not designed to deal with thick vegetation.

  • Battery-Based Gas Trimmers

These are the newest models to the market and are similar to the electric units but are not as powerful as gas weed eaters. Plus, you'll still need to recharge them constantly. A potential problem you could run into with these trimmers is when the batteries die out mid-job.

2. Power

The amount of power the motor provides is among the first things you need to know. The engine's power is measured in CCs (cubic centimetres), representing the amount of fuel and air the cylinders of the motor can push through. Generally, a higher CC translates to a more powerful engine and a higher price tag. The engine you'll probably come across in a weed eater model is the 2-stroke or 4 stroke engine. They respectively feature 2-cycle and 4-cycle motors.

3. Cutting Radius

The cut radius refers to the length of the trimmer's cutting line as it extends from the rotary. A larger cut radius means you can cut off more grass in one use. For instance, if the weed eater has a 17-inch cut radius, you can cut 17 inches of grass at a time. So, a higher cut radius could save you some time since you can clear larger portions of grass or weeds with each cut.

4. Weight

The reason you need to consider the weight of the weed eaters is that you'll be carrying it around as you move around your yard, cutting grass. The heavier models typically have larger motors for carrying more fuel, making them better suited for large yards and commercial applications.

On the other hand, lighter units are easy to use and maneuver around the lawn since they are not as tiring as the heavier options. So, as you look for the best weed eater for your premises, you should add the weight to the list of considerations.

5. Line Diameter

As you search for a gas weed eater line on the market, you'll notice there are several options available at the hardware store. Before you buy a line trimmer for your gas model, you'll need to ensure it can fit in your weed eater. However, as a general rule, a thicker line can cut through larger weeds with ease.

Fortunately, most gas models are compatible with multiple line sizes. If you're unsure of the size, don't worry, your weed eater will come with a pre-wound line that you can use as a standard for replacements.

6. Curved or Straight Shaft

The gas weed eaters on the market come with a straight or curved shaft. So, what the difference between the two?

The curved types are lighter, more stable, and compact, making them easier to use than the straight types. Since they have less torque, you won't need to generate an equal output while using the gas trimmer.

The main advantage of the straight shafts is that they are better powered to handle thicker weeds and grass. Plus, it can easily get into compact and hard-to-reach areas since it is not obstructed like the curved ones.

7. Starting Ability

You'll also need to check how easy the weed eater starts. If you have some experience with these outdoor tools, you know that it can be tricky to get them starting. That is why the weed eater needs to have a function that enables easy starting.

8. Vibration

Every weed eater produces a fair amount of vibration as you use it. This vibration makes it challenging to use weed eaters for long periods without getting fatigued or discomfort. In many cases, the shaking will cause a tingle in your hands.

Fortunately, the weed eaters in this review have anti-vibration mechanisms that reduce the amount of shaking that the tool produces. This makes it easier to use the weed eater for longer without getting too uncomfortable.
