What to Look For In a String Trimmer or Edger
A string trimmer and edger is a basic tool common around the world. This motorized device utilizes rapidly rotating strings to trim long grass and weeds that grow in yards and around driveways, walkways, and other paths. Over time, the strings break and need to be replaced by the user.
Although this tool is considered one of the simpler lawn implements, it has undergone a broad range of technological advancements in the last few years. The result is a plethora of string trimmers and edgers available for sale with different features.
To help you identify the best model for you, this guide explains the differences between modern trimmers and what traits you should look for before making a purchase.
Fuel
The most common disparity between string trimmers and edgers is in the fuel type used by the device. Old fashioned trimmers utilized a combination of gasoline and oil-fed into a fuel compartment. Through basic combustion, the gasoline/oil mixture would generate the energy necessary to rotate the strings and cut grass.
However, gas models are not as common in the contemporary age as electric devices. An electric string trimmer utilizes lithium-ion batteries to generate the energy needed to spin the strings. These batteries are inserted near the upper handle of the trimmer and are designed to be rechargeable.
Running Time
If you want a trimmer that can operate for a long period of time, then you need to get a gas model. This might be difficult, though, as the majority of companies have started to phase out gas devices for residential use, favoring the commercial market instead. The average gas string trimmer can run for several hours.
Battery operated trimmers only tend to last between 30 and 60 minutes depending on how many are inserted into the device.
Power
Battery operated trimmers are weaker than their gasoline-fueled cousins, but also tend to be lighter and easier to handle for the average person. If you consider yourself an “average Joe” with a basic yard, then you do not need the power of gas. However, it can be nice to have the extra oomph when dealing with brambles and crabgrass.
Noise
Gas-powered trimmers are loud. Extremely loud. Most people will need to wear some form of ear protection when operating this type of trimmer. When you use electric models, you get the benefit of a quieter tool that is easier to use in residential areas.
String Type
Every string trimmer and edger uses a different type of string to accomplish its yardwork feats. Strings vary in material, size, and shape depending on their designated use and the type of tool you buy.
Material
While people imagine the string in string trimmers would be made of basic fabrics, the majority are actually composed of synthetic materials designed to be stronger and easier to use. When shopping around for the ideal trimmers and edgers, you will need to choose between basic monofilament nylon and reinforced nylon.
Basic monofilament nylon is simpler to feed into the trimmer and is weaker. It works well for average jobs and can be spun at rapid speeds. If you are interested in performing heavier work, then you will want to find a feeder that incorporates reinforced nylon. This nylon is tough, doesn’t break easily, and is designed for tough jobs.
Size
The size of a trimming string can be split into three categories.
Light: Strings intended for basic yard work tend to be between .065 and .080 inches thick. This is the type of string you would use when trimming around the driveway and working with basic grass.
Medium: Strings meant for slightly more intense activity are between .085 and .105 inches thick. These can be used for cutting grass and tackling thicker weeds like crabgrass.
Heavy: A string meant for heavy-duty work and activity should be .110 inches thick or greater. These strings will last longer and can tackle tougher jobs.
Shape
Finally, you will need to choose the shape of the string. The majority of products you buy will already have a type of string in mind, so you often have to choose a trimmer that works with the shape you desire. The most common shapes include round, twisted, serrated, and multi-sided.
Round trimmer lines are less prone to breakage but also do not have any cutting edges that can rip through the grass. A twisted line is stronger and also does not break easily. When you use serrated and multi-sided options, you get extra cutting power but will have to deal with an increased amount of breakage.
Choose wisely.
Brush Cutting
Sometimes a string trimmer/edger will claim to also be a brush cutter. A brush cutter is a tool that is capable of cutting through tougher foliage, branches, and even trees. In general, you will not find a reliable string trimmer capable of brush cutting as well unless you are willing to spend hundreds of dollars to get extra attachments.
If you do want a combination trimmer and brush cutter, then you will want a gas-powered tool that uses serrated string.
Brush Guard
A powerful string trimmer and edger need a brush guard. A brush guard is a small plastic or rubber shield that stops rocks, branches, and other debris from being blown back and striking you. This can stop you from being injured and suffering cuts, bruises, and other uncomfortable injuries.
Do not use a string trimmer that does not have a brush guard. This puts you at great risk and can be detrimental for your health and regular yard work.
Dimensions
Finally, you need to consider what dimensions you are comfortable with using when it comes to your tools. Sometimes people will purchase a string trimmer and edger that is way too long or short for their grip, which results in a disheveled lawn, strained back, and difficulty in doing regular yard work.
When checking out the dimensions of an ideal trimmer and edger, check for a model that is between 3 and 4 feet long with a string that has at least a 10 in. cutting swathe. A weight between 8 and 15 lbs. is ideal for the average individual, since the arms can tire quickly when operating a motorized instrument.
Line Feeding Type
Finally, take a look at how the string is fed in the trimmer. An essential component of the string trimmer and edger is how to string is replaced when it is broken by grass and vegetation. Older models implemented a feature called the bump feeder. The bump feeder would release more string when the user tapped it on the ground.
Bump feeders have largely fallen out of fashion in favor of the more technologically advanced automatic feeder. With an automatic model, the device senses when the line has been broken and releases more string to replace it. This is ideal for average yardwork since many people do not notice when their line has been broken without some kind of warning.
The main issue a lot of gardeners have with the line feeder is that the models can be disruptive and it is difficult to tell when too much or too little string is in use. Needing to bump the feeder while the power is running can also be dangerous and result in uneven patches on the lawn. Bump feeders are therefore best used by people with more experience.
The only catch with automatic feeders is that they can produce the wrong length of string. This is why all of the products reviewed on this list have been checked for quality when it comes to the feeding sensors built into the machine.
The Best Brands
Craftsman
Craftsman is a brand originally owned by Sears but which was recently purchased by the same parent company as Black and Decker. The tools have a long reputation of being some of the most durable and high quality, capable of lasting many years when regularly maintained and cleaned.
Black and Decker
Likewise, Black and Decker are one of the most established companies that produces stable and easy to use tools for people of all backgrounds. Both brands manufacture their goods in the United States, which means they need to meet high-quality standards before they are allowed on the market.
Greenworks
If you are interested in affordability and improved environmental friendliness, then you can’t go wrong with Greenworks. This brand is relatively new but focuses on eschewing traditional fuels and materials in favor of options that are ‘greener’ and more biodegradable. The majority of products are also lightweight and easy to use, making them ideal for someone who is unused to yardwork or only has a couple of small projects to complete.
FAQ
Q: Can you mow a lawn with a string trimmer?
A: This is a common question and one without a simple answer. In general, trying to mow a lawn with a string trimmer (or edger) has uneven results and requires a lot of labor. However, if you have a small yard that is less than 750 sq. ft., then it might be easier to invest in a trimmer than purchase a lawnmower.
Q: Can I use an electric trimmer on wet grass?
A: You should NOT use electric trimmers or edgers on a wet lawn. You do not have to worry about electrocution, but the wet vegetation places extra strain on the motor and can more rapidly drain the battery. The moisture is also slippery, and it is easy to injure yourself when trying to trim the lawn when it is wet.
Q: Why won’t my device start?
A: The majority of string trimmers and edgers use a fuel combination that is part oil and part gasoline. The primary ingredient is gasoline, which forms the majority of the fuel composition. If you have tried a new fuel that has too much oil, then it is common for your device to sputter and struggle to start. Clean out the fuel canister and use a manufacturer’s recommended product instead.
Q: Can a string trimmer be used to edge?
A: It is possible to use the trimmer around the edges of your lawn, but the results will not be as clean and it is more likely to get rocks and other debris kicked back towards your legs. If you want to use a string trimmer that also edges, be sure to buy a designated tool that is designed to do both to reduce the chance of injury and ensure you get a clean cut for your yard.
Q: How big should a guard be?
A: The brush guard is one of the most essential components of a string trimmer and edger since it protects your legs from flying debris. In general, you want a guard that is as long as your strings, so use one between 10 and 14 inches.
Conclusion
When it comes to choosing the best string trimmer and edger, it’s important to take into consideration what kind of tool you want. If you want a single product dedicated to both trimming and edging, then you can’t go wrong with the Craftsman V20 String Trimmer and Edger. This model is easy to adjust, has a simple automatic line feed, and also has enough power to get the job done without needing extra charging.
However, all of these models are simple and easy to use. Thanks for reading, and happy trimming!
