Having a good string trimmer in your landscaping arsenal is the key to maintaining a neat, well-manicured lawn. With different power sources available – battery-operated, corded, and gasoline-powered engines – it can seem overwhelming trying to choose which model is the best string trimmer for your needs. For homeowners with a sizeable yard, a gas-powered weed eater is undoubtedly a better option than their battery-operated or corded counterparts.
The best gas string trimmers on the market are built to be durable, heavy-duty pieces of equipment that can trim more grass in less time. Unlike other weed eaters, their gasoline engines are strong enough to also power through thick, tough grass and maybe even small brush. Since they are designed to be more powerful, the best gas trimmers typically have a longer life than battery-operated or corded string trimmers.
There are some drawbacks to owning a gas string trimmer over one of the other power sources. They’re loud and emit noxious exhaust fumes, making them a less environmentally conscious choice. They’re also considerably more heavy and cumbersome to use, especially when carrying them around a large yard.
However, on the flip side, you’re not tethered to an extension cord, constantly dragging it around the yard as you are with a corded trimmer. Or you’re not sidelined, waiting for a battery to recharge every hour or so.
Its exemplary performance and dependability overshadow the disadvantages of purchasing a gas string trimmer. Battery-powered and corded weed eater models can’t hold a candle to these powerhouses.
Buying a gas string trimmer can seem like an overwhelming task, but we’ve combed through reviews and weighed the pros and cons to compile a buying guide with our top 10 best gas trimmers.

What to Look For When Buying a Gas String Trimmer
After you decide to buy a gas string trimmer, your journey to purchasing one is only just beginning. There are hundreds of different models to choose from that offer various features and sell for a range of prices.
This article aims to make your buying decision quicker and easier, helping you purchase the best, most dependable gas model that fits your budget and lawn care needs. We’ve done all the research to help make this an easy decision!
The best gas-powered string trimmer is dictated by what you’re looking for in one of these machines. Here are some of the critical features to consider when browsing the best gas string trimmers to help you on your journey.
The motor is the most crucial part of any gas-powered machine – it determines your equipment’s amount of power and speed. It’s essential to look at the machine’s capacity when purchasing a string trimmer. A smaller capacity motor results in lower power output and speed but helps to keep the motor weight down. A high-capacity motor has more power and speed, reducing the time it takes to trim.
Another essential aspect to consider when looking at a grass trimmer is the number of engine cycles. A 2-stroke completes all five functions in only two strokes of the piston. A 4-stroke requires four piston strokes or two full crankshaft revolutions to complete the functions. Two-cylinder engines run on a mix of gas and oil and are louder to operate. A four-cycle motor has different compartments for fuel and oil, which increases the cost, but operates quieter.

A wider cutting width allows you to trim an area in less time. Most gas trimmers have a diameter greater than 15-inches, leading to a reasonably high output of time spent working. When buying a weed whacker for a medium to a large lawn, you want to look for a model with an adequately sized spool, giving you a greater cutting width. The best models have a minimum 17-inch cutting path. It’s frustrating to purchase a heavy-duty trimmer only to find it takes forever to finish a job because of a narrow swath.
The truth of the matter is you’re going to be carrying this trimmer around your yard, hanging onto it as it vibrates in your hands. Some of the best gas string trimmers are inherently heavier than other types because of the type of motor and fuel capacity. As time goes on and you continue to trim around your property, your arms, shoulders, and back will naturally become fatigued.
Look for a machine that’s designed well so you can carry it comfortably for an extended period of time. If it takes a long time to trim, you need a model that isn’t going to tire you out quickly. If you have back or shoulder concerns, choose one with a shoulder strap to evenly distribute the weight, reducing the strain on your body.
Remember, you don’t want to go with the lightest available trimmer either. One with more heft usually corresponds to a higher engine output that improves your efficiency. The extra weight also acts as an anti-vibration mechanism too, absorbing some of the vibrational energy.
Trimmer shafts are either straight or curved; each type offer advantages and disadvantages. A curved model is usually shorter, reducing the weight of the weed eater. Their design makes them feel balanced, and they’re more comfortable for shorter users. On the downside, a curved shaft gets in the way when trimming under lawn furniture or gound shrubs. This type also has less torque, and the drive cable has a shorter lifespan.
A straight shaft trimmer will cost more money, but you’ll end up with a heavy-duty unit that generates more torque. It’s more comfortable for taller users as it extends the reach. Keep in mind that this type tends to be heavier and feels less balanced than the curved shaft models.
Fuel Tank Capacity
There’s a balance to be found between having a fuel tank with a large enough capacity to negate filling it often while keeping the overall trimmer weight down. Keep in mind, the larger the fuel tank, the heavier it will be when full, and you will tire easier. Some people might prefer a model that weighs less when full of fuel, even if it needs a fuel refill more often.
There are two aspects of the feed system to consider when purchasing the best gas string trimmer. The first aspect is the number of lines that feed from the trimmer head, and the second is how new line is fed.
Many trimmers – especially entry-level models – feed one line from the spool. They’re easy to wind but take longer to cut grass and weeds. Dual-line models take extra effort to wind a new string, but they cut twice as fast, improving your efficiency and significantly reducing the time it takes to get the job done.
The string on a weed eater is fed out of the spool via a bump feed or auto-feed system. With a bump feed system, you manually advance the string by “bumping” the weed eater gently on the ground when operating. An auto-feed system will have an automatic advancing mechanism that feeds more line when the string gets too short.
Some weed eaters come equipped with quick connects to support several outdoor power equipment attachments, such as a brush cutter, blower, or pole saw. The ability to change the attachment tool extends your equipment’s versatility without purchasing numerous pieces that need storage.
If you’re in the market for a string trimmer that takes different head attachments, look at the mounting mechanism and how hard it is to switch from one tool to another. Ideally, you want a unit with a quick change option that doesn’t require special tools to change attachments.
Once you’ve narrowed down your selection of the best gas string trimmer to a couple of models, take the time to go down to the local equipment dealer and get your hands on at least one or two weed eaters. Getting a feel for the unit will give you an idea of whether the handle is in a good spot and how well the weight is balanced along the shaft.
The best trimmers should be chosen for their prevalent features, their reliability, and their warranty. They take a lot of abuse, and there’s always a chance that parts will break or the engine will have problems.
When looking at gas string trimmers, check out the manufacturer’s warranty, including what parts are covered, the length of coverage, and any stipulations you must follow to ensure you don’t void any part of the warranty. A good warranty means little need to worry about breakdowns and replacement costs.
A good gas string trimmer is an important equipment investment when it comes to caring for your yard, but choosing a high-quality model can be daunting, especially if you’re a new user looking to buy your first trimmer.
Gas-powered weed eaters are known for their duty, capability, and power. All ten models included in this list are highly-rated by consumers and offer various equipment features to meet your yard and budget needs.
When purchasing a trimmer, keep in mind the unit’s output and speed, if it’s a two-cycle or four-cycle, and the cutting width. These factors vary between models. They impact how quickly you can manicure your lawn and what type of fuel the trimmer requires.
Beyond that, you can look at features such as weight, shaft length, fuel capacity, and feed system to find the best gas string trimmer for you and your yard duties. Taking the time to find the best gas string trimmer for your situation will pay off once you can sit back and enjoy a landscaping job well done.
Frequently Asked Questions
Q. What is a weed eater?
A. This is a powered tool that uses a single line (string) that rotates at a very high speed to cut grass or to remove weeds. The machine uses the principle of centrifugal force in its operation. The head is held by a long shaft, and the device is ideal for yards with obstacles or steep terrain. Weed eaters are categorized into gas, electric, and battery-powered. The types are based on the kind of power that the machine uses.
Gas weed whackers are the most powerful though they emit fumes and maybe a bit heavier. Battery trimmers are ideal for small lawns but could be located far from the power source. Lastly, electric weed eaters are suitable for yards near the power source (electricity).
Q. How to use string trimmer?
A. After purchasing your weed trimmer, you should assemble the parts using the user manual. Then, ensure that you have enough power to run the machine. For two-cycle power equipment, you should mix fuel and oil in the correct ratio. For electric weed eaters, make sure that the cord is long enough to reach the furthest corner of your yard. Check the battery level of a chargeable trimmer to ensure you will not need to recharge after a few minutes.
Ensure that the thread is in good condition. If you realize the line is worn out, it is advisable to replace it to have the greatest output. The yard should be free from stones or other obstacles which may lessen the life of the string. Hold the machine close to the ground before turning it on. This reduces the impact of vibration because the grass trimmers seem to be more vibrant when not in use.
You will also get the best trimming position before start off. Turn on the machine and start trimming a few centimeters above the ground. Unless you want to replace the string, you should avoid tapping the head on the ground because you will waste the line. It is advisable to relax if you feel that the impact of the whacker strains your body.
Q. How to install a string trimmer line?
A. Place the machine in a position where it is supported to access the spool. Remove the spark plug wire from the spark plug taking care not to hurt your hands. You should be in proper work gloves when replacing the wire. Ensure that you have the right diameter of the line to avoid jamming your gas-powered tool. Locate the starter whole where you are supposed to attach the tip of the line.
After inserting the string, you are supposed to wind the spool in a clockwise direction. Lastly, line up the retainer with the outside slot and pull it through until it feeds smoothly. You are good to place the cap and start trimming with your new line.
Q. Do String Trimmer use regular gas?
A. Most whackers use unleaded regular gas. The four-cycle engine uses pure gas while two-stroke engines use a mixture of fuel and oil. You should ensure the two are mixed in their right ratios if your machine is to work efficiently and serve you for years.
