This detachable model is designed with smart start functionality that makes it easier to start trimming the weeds in your yard or garden. There is a function that is designed to remove all of the air from the engine and the carburetor so that the trimmer can easily access the fuel when it needs to start. In addition, the start switch will also reset back to the starting position when it is turned off so that it can easily be started again.

This is a lightweight trimmer model that is easy to maneuver around your yard. The handles are designed with an ergonomic shape that is easy to hold, and the shaft can be removed from the body of the trimmer so that it can be transported to other spaces with ease. In addition, the 17-inch cutting diameter makes it a great tool to use for a larger space.

This is a very versatile trimmer that is designed to be able to accommodate nearly any gardening needs. There are 11 different attachments that can be used with this trimmer, and they are all professional grade tools that will be useful in some way. With these attachments, you can trim your hedges, shape your bushes, prune your trees, and much more.

Some of the attachments that require the trimmer to be inverted when they are being used are not as effective as they could be. For example, the pole trimmer seems to struggle to get the gas that it needs to trim branches adequately.

Verdict

This is a very versatile trimmer that is designed with a lot of attachments. It has a large trimming diameter, and it is easy to carry through your garden. A carry strap would be a welcome addition to the trimmer, but it is still a great option without one.

Pros

  • This gas string trimmer has quite a bit of power.
  • Starting this trimmer is a very simple process.
  • Replacement trimmer line is very easy to install in this unit.

Cons

  • This is a trimmer that seems to go through gas very quickly.

The debris guard that is located at the base of the trimmer is very small, which means that if there is any rubble or debris in the weeds that you need to trim, they will most likely be flung out of the unit when you are trimming your garden or yard.

Verdict

However, only having this amount of string in the trimmer at once means that there is less chance of the string getting tangled, so you will simply have to replace it more often.

Verdict

Pros

  • It is very simple to start this trimmer.
  • The unit vibrates very little while it is being used, which means that it is easier to handle when you have a lot to trim.
  • This trimmer has an extra long shaft that is designed to make it easy to reach under shrubs and bushes.

Cons

  • It takes a bit of effort to bump the cord when you need new string.
  • The debris shield seems like it could be a bit larger.
  • The throttle lever is plastic, which means that it is not as durable as it could be.

In addition, this unit is compatible with 10 different attachments, so it is a versatile tool to use in any garden.

This is a very heavy trimmer to carry around a large yard or garden. In total, it weighs about 18 pounds, so you may need to invest in a strap that makes it easier to maneuver when you are using it to trim your yard.

As a trimmer, this is a very great option to consider, especially if you need to trim, cut, and edge the shrubs and the grass in your yard or garden. Though it is a bit on the heavy side, it will get the job done easily, even when the weeds are thick.

Cutting Width 15-Inch
Starting System EZ start recoil system for quick, easy starts
Product Dimensions 37.4 x 11.61 x 12.2 inches
Item Weight 17 pounds
BUY ON AMAZON

Features

  • 2 in 1 Brush Cutter/Trimmer
  • Anti-vibe handle increases stability and comfort
  • Powerful 2-stroke, 42.7cc engine is designed to cut through extreme ground cover conditions
  • EZ start recoil system for quick, easy starts
  • 3-prong brush cutter blade cuts vegatation up to 1 in. thick

When you're working in the yard, the vibrations that a trimmer can generate can be more than a bit uncomfortable, which is why the anti-vibe feature of this Blue Max trimmer is so useful. This is also a trimmer that's designed to be lightweight, so hours spent in the yard won't be as fatiguing as they would be with even a slightly heavier product.

The two-stroke engine of this product is also very powerful, which means that you shouldn't have much issue clearing through even the thickest brush.

This trimmer is designed with a straight shaft that makes clearing grass and brush very easy to control. Couple this with the 42.7cc engine and gardening is relatively easy with this Blue Max trimmer. The product uses a gas/oil mix of 40:1, and it runs fairly cleanly during your gardening duties. It also has a recoil starting system that makes it a cinch to get going quickly, and the handles are positioned in such a way as to be very ergonomic.

This product comes with a shoulder strap that isn't very well-made; in fact, it's fairly easy for it to wear out over time, and it's simply going to be better for you to purchase a harness. Also, the spring-loaded clip that binds the top and bottom together can be a bit rickety and can fail in short order. Additionally, the motor can bog down if you're cutting through thicker items like saplings.

Verdict

Overall, this Blue Max product is a good option for anyone that needs a product that has a lightweight operation and wants something that's got enough power for thicker applications as well. Also, since this is a hybrid product that will trim and cut through heavy duty brush, this is a great overall product for versatility.

  • Its straight body makes it very easy to control.
  • The handles are very ergonomically placed.

Best gas string trimmer - Buyer's Guide

Gas trimmers are not the only type of trimmer that you can purchase. There are also electric- and battery-powered options that are available on the market as well. With that being said, gas-powered string trimmers tend to be the most powerful option, which makes them great for large gardens and lawns. However, these are often the most expensive option, so you will need to consider your budget before making a purchase. Don't forget to take the fuel that you will need for the trimmer to run into account. It will not be a lot, but it is an added cost that you will need to consider.

What are other important features to consider?

One of the first things that you are going to need to consider is the shape of the shaft on the trimmer. You are going to need to have a trimmer that is comfortable to hold so that you are able to trim your entire yard or garden without getting fatigued. That being said, there are two types of trimmer shafts that you can consider.

Shape of the Shaft

The first, which is a curved shaft, is best for smaller areas. These models are typically lighter in weight so that they can be maneuvered with ease. They are also shorter in length, which can make it easier to trim small weeds in a flowerbed.

The second type of string trimmer shaft that you can consider is a straight shaft. This one is designed to be used in yards that have dense growth because the heavy-duty design has a longer reach that is great for trimming under bushes where a lawn mower cannot reach. Since these trimmers are larger, they may be more difficult to store.

Cutting Diameter

The cutting diameter of the string trimmer is basically the amount of weeds that can be trimmed in a single pass. If you have a small yard or garden, then you will only need to have a cutting diameter of about 10 to 14 inches, but if you have a larger space that needs to be trimmed with a gas string trimmer, then 15 to 18 inches is most likely going to be preferred.

Type of Engine

Gas trimmers can have two different types of engines. The first is a two-cycle engine; this is the more economical option if you are looking for a simple trimmer to trim the weeds in your yard. The second option is a four-cycle engine. This option is a bit more expensive to purchase, but it is designed with a little bit more power so that it works for larger jobs as well as small ones.

Easy to Maneuver

Regardless of the string trimmer that you select, you are going to need to choose one that is easy to move around the yard. Many of the models on the market are handheld, which gives you fewer restrictions as you use the trimmer; however, if you are using the device for a large yard, these types of trimmers can become difficult to manage. Some are designed with shoulder straps to help take some of the weight off of your arms as you use the trimmer, but trimming your yard or garden still makes you feel fatigue, then perhaps a trimmer that has wheels is a better option for you to consider. If you need to trim an area that is overgrown, then this may be the most efficient option for getting the job done.

Type of Trimmer Line and Feed System

There are two types of trimmer line that you can choose for your trimmer. This line is effectively what cuts the grass, so you will need to make sure that you select the right line for your needs. A standard line is designed for most lawns. This type of line does not cost a lot, so it is often the choice of homeowners. If you have a thicker area that needs cleared, then a commercial grade line is going to be able to clear the area with ease.

When it comes to the feed line on the trimmer, you will have two options to choose from. The first is a bump feeder, which will replenish the line as the old one needs to be replaced. There is also a fixed line that is a set length, which means that when it needs to be replaced, you will have to remove the old line and replace it with a newer one.

Maintenance Requirements

As with any gas-powered device, there are things that you will need to consider to maintain a string trimmer so that it functions season after season. First, you will need to make sure that the gas tank is free of any external or internal dust and debris, the oil will need to be changed somewhat frequently, and the motor will need to be cleaned thoroughly as well. It is always best to check the trimmer line and the amount of fuel that you have remaining after each use so that it is ready to go when you need to use it.

Final Thoughts

All of the gas string trimmers that we have reviewed in this guide are great options to consider. However, every garden or yard is not going to have the same needs when it comes to trimming, so what works for one individual may not be the best option for you. Hopefully, this guide has helped you find the right trimmer for the job, but if you are still searching, use the buyer's guide to help. Gas trimmers are powerful tools, but they still emit emissions, perhaps in the future, there will be a more eco-friendly fuel source for trimmers that will operate more cleanly and for a longer period of time.
