Gas Weed Trimmers Reviews: Best Models & Recommendations

For this section, I picked seven most reliable and cost-effective gas grass trimmer models and wrote a detailed review and recommendations for each one. Read them thoroughly, and you’ll be able to choose the best gas weed eater for your purposes without problems.

Echo GT-225 2 Cycle 21.2cc – Best Gas String Trimmer

Echo is one of the top brands on the market of handheld power tools for commercial and personal use. The brand has high-quality support, offers competitive assembly quality, and some of the most reliable 2-stroke engine models with a 5-year consumer warranty and a 2-year commercial warranty. Echo’s trimmers are not only powerful but also have low emissions and meet both CARB and EPA standards.

The GT-225 is my favorite lightweight gas weed eater. It combines the compact design of a home-use tool and the heavy-duty sturdiness of a commercial instrument. The weight of the device is just 10 lbs, while the motor power is 21.2cc. It’s equipped with a patented i-30 starting technology, which makes it significantly easier to start. The 48” curved drive shart has a sturdy 4-cable drive with a large 16” Rapin Loader cutting head on end.

I recommend this model for all average purposes, including the trimming of large lawns. The curved shaft offers high maneuverability, while the high cutting width lets you cover larger areas in less time.


PROS:
  • Powerful and compact tool;
  • High maneuverability;
  • Sturdy 4-cord drive;
  • Large 16” cutting width;
  • The lightest gas weed trimmer.
CONS:
  • The fuel tank could be a bit bigger.

Husqvarna 128LD 17″ Gas String Trimmer – Powerful Straight Shaft Weed Eater

Husqvarna is the largest manufacturer of gardening power tools in the world. This Swedish company has been in business for almost 400 years and has experience in manufacturing not only power tools but also high-quality firearms. Well, this company is older than the US, which is definitely a sign of quality and traditions.

The 128LD is a powerful 28cc straight-shaft machine that comes with a large default 17” trimmer head. The firm string replacement system is a pleasure to use as it lets you change the string fast and painless. I think it’s a crucial feature for commercial users. Moreover, you can quickly release new cutting lines. Simply tap the trimmer head against the grass to use the feature. I can’t say that it works perfectly well, but it’s definitely a unique thing to try.

Other benefits of the device include capability with several attachments, including an edger, a cultivator, and a pole saw. It’s an excellent choice for both occasional and professional gardeners who need a bit more power with a straight shaft. By the way, you can easily detach the shaft for more convenient transportation in your car’s boot.


PROS:
  • Straight shaft;
  • You can release new lines on the go;
  • COmpatible with different attachments;
  • 2.6-oz of oil is included;
  • Detachable shaft.
CONS:
  • The Tap’N’Go feature needs more precision.

Poulan Pro PR28SD – Best Alternative to Husqvarna

Poulan Pro is a native American brand and a high-quality sub-brand of Husqvarna. Although this device is based on different engineering approaches than the previous one, it offers the same level of convenience and excellent capabilities. The good news is that Husqvarna shared the Tap’N’Go feature with Poulan so that you can benefit from it with this tool too.

While the engine specs are almost identical to the Husqvarna analog, the ergonomics of the model are slightly improved. The shaft holder is much easier to adjust as it doesn’t require a screwdriver to release the part and move it to the needed position. It’s also very easy to detach the shaft for transportation. This weed eater is excellent for professional and personal use and lets you easily trim hard-to-reach areas.


PROS:
  • Good for hard-to-reach areas;
  • Easily adjustable hold;
  • Wide range of settings;
  • Convenient air purge;
  • Easy to transport.
CONS:
  • The warranty could be longer.

Remington RM25C 25cc – Lightweight Curved-Shaft Trimmer

Remington is a well-known American manufacturer of power tools that offers excellent quality and reliable support. RM25C is an excellent alternative to Echo GT225 as it offers the same curved shaft and a Husqvarna-style trimmer head with a tap extra line release mechanism.

It’s an excellent device for small and medium lawns as it has low fuel consumption, and you won’t get tired by carrying it around without a strap. The only disadvantage is the location of the power circuit switch. Why is it placed away from the handle?


PROS:
  • Lightweight design;
  • Curved shaft;
  • 16” cutting width;
  • Adjustable handle;
  • Tap extra line release.
CONS:
  • The power switch location is weird.

Craftsman WS205 25cc – Basic Cost-Effective Solution

Craftsman is a 93-year-old US-based manufacturer with one of the best customer support services and reliable assembly quality. WS205 is a lightweight device with a small 25cc motor and a wide 17-inch cutting ability. Due to these characteristics and conveniently adjustable design, you can use this trimmer for hard-to-reach places and quick trimming on open areas.

The gear head is easy to replace with a variety of nozzles by Craftsman and other compatible brands. However, I’d not recommend to use it for brushwood, and similar power-greedy tasks as the engine are designed for grass and dense weeds. Not more. I recommend it to anyone who has a small to medium garden and average trimming purposes. Craftsman offers great value for money and simple exploitation.


PROS:
  • Lightweight model;
  • Adjustable handle;
  • Compatible with third-party heads;
  • Easy to start;
  • Good price.
CONS:
  • Warranty length is not mentioned.

COOCHEER 42.7CC 2-Cycle String Trimmer – Best 2-in-1 Solution

This brutal weed eater is equipped with a powerful 42.7cc 2-stroke power unit and an extra-long 62.2” straight shaft. Of course, the item is notably heavier than the previous models in my review, but it’s also much easier to hold. The default package includes an adjustable strap and a 25” two-arm grip with built-in remote controls. The good news is that the package also includes all the needed instruments for assembling and adjusting the tool.

Due to the extra powerful 2-stroke engine, this trimmer is very similar to brush cutters. As a result, you can apply brush cutter blades with this device. The manufacturer recommends using the default star-shaped blade for heavy brush, but I’ve successfully tested several other nozzles too, By the way, you can already read my reviews of the best brush cutter blades on my blog.

I recommend COOCHEER’s 42.7cc string trimmer for gardeners who look for a powerful combined solution that can deal with anything from grass to dense brushwood. It offers the best value for money as well.


PROS:
  • The best delivery kit;
  • As powerful as a brush cutter;
  • String trimmer head and a star-shaped blade included;
  • Two-hand grip;
  • Up to 7000 RPM.
CONS:
  • High fuel consumption;
  • Rather heavy.

PROYAMA 42.7cc – 2 in 1 Extreme Duty Gas Trimmer

Similarly to COOCHEER, PROYAMA offers an extra-powerful heavy-duty tool with a large variety of capabilities. In fact, it’s a full-value brush cutter that can be used as a conventional trimmer. The tool has a convenient U-shaped handle and a full-shoulder strap system that makes it a pleasure to carry the tool the whole day long.

In addition, the package includes a load of surprising bonuses, including protective glasses, on-ear noise protection, gloves, and 3 extra blades. Using a wrench, you can easily turn the trimmer into a powerful brush cutter with a 40-tooth carbide blade, star-shaped blade, or the monster chainsaw chisel blade that can easily cut through dense brushwood.


PROS:
  • Universal multi-item kit;
  • Powerful engine;
  • Brush cutter capabilities;
  • Good value for money.
CONS:
  • Metal quality could be a bit better.

How to Choose a Gas Weed Trimmer

Craftsman WS205

This part can be a bit difficult to remember, but it’s crucial for you to shop successfully, especially if you are going to make a purchase online. Study each point below to get a clear understanding of what you need and what’s not necessary.

Engine Power

In most cases, weed eaters are equipped with 2-stroke engines that offer an excellent balance between performance and durability. They’re notably easier to maintain and include fewer parts, so you can expect them to break very rarely.

Four-stroke engines are much more powerful but require more maintenance, cost more, weigh more, and are more difficult to repair. On the other hand, they’re more cost-efficient as the 4-stroke system doesn’t lose fuel while operating and uses a separate oil injector, which is a time-saving feature. I recommend this type to professionals and owners of large gardens who need higher efficiency.

Cutting Width

In most cases, the cutting width is between 12 and 14 inches. The bigger it is, the more grass you can cut per second without moving the tool. Low width is perfect for small gardens and smaller machines that offer higher maneuverability. The high cutting width is a must for large gardens. There’s no general rule to follow, so you should choose the one that is more comfortable for you.

Trimmer Weight

Average weed eaters are usually significantly lighter than brush cutters, but always heavier than battery-powered trimmers. Gas-powered models can be split into two major weight categories. The first one is designed for homeowners and usually weighs from 9.3 lbs to 10.6 lbs, while the weight of professional line trimmers can vary from around 10.6 lbs to 15.9 lbs. This feature depends on a brand and depends on the tool’s length, engine type, fuel tank size, filter size, and other parts. You should understand that the lower the weight, the less powerful your tool can be. Of course, technologies don’t stand still, but this dependency remains a general rule.

Length of Shaft

First of all, you should see the difference between the curved and straight shaft types. The straight shaft is better for trimming around and under trees and fences. A long and straight shaft will keep you away from high-speed debris. It also makes it a lot easier to cut underneath hedges, fences, and around bushes. On the other hand, longer shafts are also a bit heavier and require a bit more strength from you to operate. Short shafts require a bit less movement and save you some energy.

A curved shaft is more convenient for trimming grass and weeds on open ground. As for me, it’s a bit more difficult to maneuver but easier to choose the proper height while trimming on open ground. Choose this type if that’s what you need, but be ready to face heavier attacks of debris if you take a device with a short shaft. You don’t need a long shaft if you have a small yard as it may lower your maneuverability, but it’s up to you.

Safety Features

Line trimmers spin the cutter extremely fast and can shoot debris at high speed. I recommend you to give preference to models that are equipped with guards to save you from shrapnel. At the same time, you shouldn’t neglect additional safety measures and wear gloves, eye protection, long pants, and long sleeves. Believe me, and you will have injuries if you don’t follow these simple rules.

Materials

Gas weed trimmers are usually very durable, and it’s easy to maintain them because they have exposed lines. To my mind, you should also look for models that use bump feeding technology as they’re simple and break rarely. In most cases, simplicity is the key to durability. You should also avoid trimmers with too many parts that are exposed to corrosion or easy to break by accident. Besides, you should use strings only of the recommended thickness and length to avoid malfunction.

How to Use a Gas Trimmer

I’ve already taught my new neighbor how to master his tool as gas string trimmer reviews never tell about it, so many users face frustration and work slower than they actually can. Here are the rules that I follow to use my wacker effectively.

Mind The Spin Direction

You should always mind the spin direction of the trimmer head as it defines the direction of debris ejection. Depending on this factor, you should position the head of your tool properly to let the clippings eject in the most convenient direction. You don’t want the grass to stick to the fence, right? Always walk in the same position to pile up the clippings towards the path.

Practice Cutting Techniques

Unfortunately, cutting the grass with a trimmer isn’t as easy as hovering the tool above the ground. You should focus on proper cutting techniques to achieve the needed precision. Your moves should be free, fast, and steady at the same time. There are four main ways to cut:

  • Tapering – this method is the best for cutting near walls, fences, and trees. You should hold the tool at a slight angle to achieve the same height as the mowed lawn. This way, you can control the length easier and avoid scalping.
  • Edging – I usually use this technique to achieve the right length on the edges of the lawn that border with walkways. You have to hold the trimmer vertically for this. Don’t be afraid to pull up some debris doing this as they will end up totally after a few weeks of regular trimming.
  • Scything – this one is good for trimming near obstacles or in tall grass. Move the trimmer head in shallow U scythes and overlap the scythes to even the length.
  • Screeding – this one’s good for cutting weeds and grass in cracks. You should carefully choose the angle to touch the grass with the tips and not to damage the strings.

FAQ

Husqvarna 128LD 17

If you still have questions after reading my gas weed eaters reviews and tips, this FAQ will answer them. I picked some of the most common questions from my readers and subscribers on social networks, so they should be helpful if you’re new to the topic.

How to start a gas weed eater?

Starting a weed eater can get quite tricky, especially if you’re a newbie. It’s important to follow several steps to avoid making mistakes:

  • Use the right gas mixture – two-cycle and four-cycle engines need different fuel types to work without failures;
  • Seal the fuel tank tight;
  • Flip the kill switch – this switch is used as a circuit breaker, and you cannot start the engine without flipping it;
  • Turn the choke on – the choke is used to make it easier to turn the engine on by restricting the airflow. You don’t need it if you want to start the warmed-up engine;
  • Press the purge valve 5-6 times – similarly to the previous step, and this action is needed when the engine is cold. The purge lets you pour some fresh fuel into the carburetor.
  • Pull the throttle cord up 2-3 times – usually, it’s enough to start the engine;
  • Switch the choke back to the OFF position to let the air flow freely. If you keep it in the closed position, your weed whacker will consume too much petrol.

What kind of gas does a weed eater use?

The majority of wee eaters are equipped with 2-cycle engines that require fueling with a mixture of gas and oil for proper piston lubrication. The required ratio of gas and oil in the mixture depends on the brand. Most machines require 87-octane fuel with 10% ethanol, while the right oil quantity is always mentioned in the user manual.

How to restring a gas trimmer?

This one needs a step-by-step instruction. The procedure is similar for one-line and two-line trimmers. Just follow these steps:

  1. Get the line – purchase the trimmer line of the right length. You can find this information in the manual or on the manufacturer’s website;
  2. Make sure the engine is off and cold;
  3. Put the retaining cap off the trimmer head – the mechanisms are always different, but intuitive;
  4. Wrap the new line around the trimmer head – make neat rows to avoid jams and snap the ends into the spool retainers.
  5. Put the spool back, line up the retainer with the slots, and pull the line ends through the slot (or slots).

How to clean a gas weed trimmer?

Cleaning your gas grass trimmer, you should stick to safety rules and be careful with the parts to avoid breakages. Here are the main steps to follow:

  • Disable the power source – you should empty or detach the fuel tank. I leave the fuel inside if I plan to use the trimmer right after cleaning, but I always empty it before storing;
  • Remove dirt – take a stiff brush and remove all the debris, dust, dirt, and clippings. You should remove everything to avoid caking. Use warm soapy water if it’s too hard.
  • Clean the filter – do it after every 10 hours of use. Remove the cover, take the filter, and wash it in warm soapy water. Rinse it with clean water and air-dry before putting it back.
  • Clean the Spark Plug – remove it with a socket wrench, and wash with a brake cleaner. If the tip of the plug is black, get the new one. If not, put it back.
  • Get back to work, or move the trimmer into storage.

Still Not Trimming?

Knowing all the answers and things to look at while choosing a gas weed wacker, you can easily pick up the proper model for your gardening needs. I recommend you to look for a tool that offers a bit more than you need at the moment so that you were able to do heavier tasks if they appear.
