A gas weed wacker is more powerful than its battery-powered counterpart. In this guide of gas weed trimmer reviews, we’ll show you how to choose the best tool for your needs.

How do Gas String Trimmers Work?

To their name, gas string trimmers run on gas. They are preferred for their power, reliability, and relatively long life. String trimmers have a small engine which rotates a nylon string at a speed of about 10,000 rpm. The string is what cuts through weed grass and shapes bushes. Some trimmers may have two nylon strings, but the working principle remains.

In some gas string trimmers, you can change the speed of rotation based on the task at hand. In gas models, the engines are more powerful, and thus the speed of rotation is higher. The nylon string wears out with time, and a new one has to be bought eventually.​

Below, a video on the differences between gas and cordless string trimmers:​

Advantages and Disadvantages of Gas String Trimmers

Gas string trimmers run on a combustion engine with a power between 15 and 22cc. Most use a double line of spool, but some have a single line. Even the best gas-powered weed eater is not designed to accommodate plastic or metallic blades. Given their higher power, these trimmers can be used on large lawn sizes. They do not need connections since you just need to refill them with gas and this enhances their portability.

There are both 2-cylinder and 4-cylinder engines; 2 cylinder engines run on a mixture of gas and oil while 4-cylinder engines run on gas. Even the best gas trimmer has one main disadvantage: these trimmers are relatively heavy. Seeing how you’ll be needing to add gas to the tank, you have to factor in the weight of the gas on top of the stated weight. In most cases, you will need to use a shoulder strap.

Though there are models that are fitted with anti-vibration systems, most gas-powered string trimmers transmit a lot of vibrations to the user. Some are comfortable to use as they absorb vibrations and their weights have been trimmed. Keep in mind that, being gas-powered trimmers, they pollute the environment.

Nonetheless, the great engine power delivered by these tools surpasses the disadvantages. They are preferred by lawn care professionals and homeowners with large lawns. You might also consider this if you need fast lawn manicures and weed cutting. If you have a small yard, however, a different type might suit you better.

Choosing the Best Gas Powered Weed Eater of 2018

With so many brands on the market, it is a challenge to choose the best. As a rule of thumb, your needs will dictate the machine that you buy; consider what you need and your budget, and use that criteria as a guide when choosing a trimmer. You can consider gas trimmers reviews online, but you still need to consider certain factors:

  • Ergonomics: The construction of the trimmer determines how comfortable it feels when in use. All trimmers vibrate, but some have features to dampen the vibrations. The best lightweight gas weed eater might only need a top mounted handle to give the user control. Bigger trimmers are offered with shoulder harnesses to offer enough support, allowing users to work for extended periods. While most are offered with a single handle, some are designed with a secondary handle.
  • Features: Gas string trimmers are simple tools with only a few features. Some of the simple features to look for include easy starting systems, spool type (single or double), and gas saving features. Most of the features on these tools are striking on many brands. Features will determine the performance of a trimmer, consider the speed of rotation and the power of the machine; this will, of course, depend on your needs. A good trimmer should cope with any task you throw at it.
  • Straight vs Curved Shaft: Though this will be heavily influenced by your preference, a curved shaft feels more comfortable in general. The shaft is designed ergonomically, and you can hold it facing down. A curved shaft maneuvers easily, and seeing how the strings will be parallel to the ground, you will be cutting in straight lines. A straight shaft trimmer is great for thick bushes and weeds, as it allows you to reach longer.

    Straight shafts are preferred by professionals. Given their straight nature, the drive cord runs through a hollow shaft reducing friction. To this end, they last longer. Straight shafts are slightly more expensive than curved shafts.
  • Safety When Using a Gas Weed Eater: Gas weed eater reviews show that weed eaters are powerful, and as such, care should be taken when using them. When the tool is rotating at 10,000 rpm, a lot of debris flies; therefore, you’ll be wise to wear work boots, work pants, and a long-sleeved shirt. In case you are using a loud model, also be sure to wear ear protection. Before using your new weed eater, read manual instructions.
