Best String Trimmers 2019 Reviews and Buying Guide


One of the biggest challenges that any home owner has is the care or upkeep of their garden or front lawn. And it’sno longer about simply mowing lawn, but maintaining vegetables, flowers, trees and plants that you have growing there. Then, you have to keep grass from growing all over the pathways, verge and finally comes weed removal.

Whether you have sprawling lawns or a garden you tend to yourself everyday, one thing is for certain – that weeds can grow fast and destroy any garden easily. The simplest way to get rid of them is to remove them and making sure it stays that way. Now, you could get on your knees, search for weeds and pluck them out. But that would take a lot of time, is tough and there’s always a chance that you’d miss a spot. Luckily, we’ve got weed trimmers for that and the most popular one being a string trimmer.

String trimmers or strimmers are an automated, mechanised versions of the original weed whackers and you can find three kinds on store today – electric or corded, gas powered and battery powered. They’re called string trimmers because they use a filament thread for cutting instead of blades.

Top 10 Best String Trimmers Reviews

Electric string trimmers are suitable for smaller gardens, are lighter, cheaper, quieter and easy to take care of. They do however have limited reach owing to the fact that they use power outlets or extension cords to remain active.
Then there’s the battery powered kind that has more portability and can handle small to medium gardens. There’s no cord or fuel required and no emissions. You do however have to keep buying batteries suited to the model you have and keep it ready when clearing out a larger garden.

Next is the gas trimmers that works with big gardens and have to be fitted with two or four cycle engines – two cycle engines need an oil mix of engine an fuel oil. Four cycle engines don’t. They’re easier to start, run smoothly and because they’re more powerful can last for a longer run. Gas trimmers are expensive, emit fumes, and are noisy.

Based on their specifications, you have a number of brands and models to choose from. This guide lists the top ten string trimmers available online and in your local gardening stores.

Best String Trimmers buying guide and pro tips:

The string trimmer really is an essential, time saving tool for those with gardens and lawns. When you go to the store to buy a string trimmer, you have to remember 2 things. One is what would really would cut the grass better and the other is how tall the grass is and how much you’ve got to cut.

Based on that, a trimmer is good for gardens that don’t have a lot of overgrowth or only need minor daily edge trimming. The next question is which one is the best one to buy? This usually all depends on the garden you have. For instance, if the garden is bigger, then a gas trimmer would be best. And if the garden is small, then and electric trimmer will do.

If you’re in an area that receives a lot of rain, then stick with gas trimmers instead because battery powered and electric trimmers will get spoilt easily. In any case, it’s advisable to water the lawn or garden after you’re done trimming it. Gas trimmers are considered to be more powerful and are suited for commercial properties, the only downside is that they emit gas fumes and have to be refilled using special fluid oils. They are noisy as heck and you even have to wear special mask and earplugs for your own protection.

Types of Products:

Weknow that there are many kind of trimmers in the market for you to buy. Battery trimmers, gas, and cordedtrimmers. Gas trimmers have the advantage of being able to clean up bigger yards and that’s why you’ll find them usually with 16 to 18 inches cutting swath. You do need to put up with maintenance, noise, weight and fumes though.

One variant is the 2 cycle engine with individual choke, primer, and throttle controls and runs on a mixture of oil and gas. The other variant is the 4 cycle engine that is costlier but worth every cent. They’requieter, easy to start and use, emit fewer fumes and don’t need a gas-oilmix.
Electric trimmers have the benefit of being lightweight and portable, less noisy and affordable where you can easily find one under $50. On the other hand they have much less power output, limited battery life or cord reach.

The corded variant is suited for your average suburban yard, assuming these homes have outdoor outlets and extension cords for extra reach.

The battery variant handles grass and weeds in small gardens exceptionally well. You do need to set aside time for charging batteries and keep a spare on handy if you want a longer run.

What's the need for the Best String Trimmers?

Weed eater, weed whacker, line or string trimmer, this tool is essential for daily lawn maintenance and care. They’re invaluable in cutting blades of grass that your standard mower can’t reach like fence posts, tree roots, shrubs, rocky textures. This solution prevents grass from overgrowing to an extent where it might costs you thousands of dollars to get rid of then.

Commercial landscaper and home owners alike need some kind of trimmers for their needs, which are very different. If you use the wrong trimmer, you’ll have a tough time cutting through thicker weeds and grass. Choosing the right line is important too, so the thicker the line is, the better the cutting load it can manage.

On commercial properties, string trimmers are easy, faster and an indispensable tools in keeping vast lawns manicured. On residential properties, they save time and money and there’s no need to hire the professionals. Adding to which they’re noiseless and won’t disturb the neighbours. They are more economical than other gardening tools and all replacement and spare parts can be bought in most stores. Installing these parts are easier too. Seniors can use them as well, because they don’t have the same strain that comes with using a mower

Who should use String Trimmers?

From professionals, home owners to real estate developers just about anyone can use a string trimmer. If you’re home has a garden with a lot of landscaping done on it, you may have to invest in a string trimmer. In fact, it’s pretty easy to use one and you don’t have to be a professional before you can start using this fantastic tool.

Operating the tool is as simple as pressing a button and in case of gas powered, simply fill the fuel before use. So, it’s good for those who want a simple, cost effective way to tidy up their lawns.

It’s convenient for old children and elder people to use as well, as they are light and easy to manoeuvre and in all cases, finishes a very messy job quickly. On an average, cleaning out weeds manually takes hours and you never really get a clean finish.

String trimmers don’t have a very bad impact on your surroundings. Battery or electric powered units wont disturb those living close to your home. So, if you don’t want fumes, don’t wish to anger your neighbours and have to work the garden in the summer heat, the string trimmers is a better option.
Maintenance and repairs are cheaper too. There’s fewer repairs involved because of the smaller number of parts. They are good for those who don’t want to spend too much on garden tools but at the same time want a decent looking garden.

The final verdict: If you need a cheap option, then electric trimmer is the best on you’ve got taking into consideration all of the other benefits discussed earlier. Electric trimmers do have cords and if you don’t have any power outlets 100 feet of where you garden is located, then go for the gas or battery powered one.

If your garden has been overlooked for too long and you need some serious power to get it under control, you need the gasoline trimmer. These trimmers are only easy to use if you know which one to buy for yourself, You also do have to have a basic understanding of RPMs, suitable filament and when this needs to be changed.

Trimmers also come with automatic feed and bump feed systems to advance lines as and when they wear out. automatic feeds work by sending out more of the line as the string gets shortened through use. The advantage of this is that you can focus on where your cutting and not the string. Automatic feeds can get jammed or broken easily, in which case you have to manually pull it out. Bump Feeds work by pressing the trimmer against a flat surface to activate a spring loaded head filled with extra string length. In this system you can control how much of the line you use, reducing the number refills required. If it stops working, you can easily get it repaired too. The disadvantage of this is that if you use too much force, you could easily crack or damage the spool.

Coming back to the topic of spools, you can find pre wound spools ready on retail shelves that only have to be loaded onto the trimmer head. The problem with this is that you may have to look for spools specific to your trimmer models to get one that’s fits on easily and wont’ come off during use.

Then again, certain models may not have a replaceable head. This means that you need to buy separate rolls of filament and roll them onto the spool yourself.
StorageWise: Trimmers are longer, thinner and more compact regardless of whether they have a folding shaft or not. As opposed to bulky tractor mowers or hand held mowers, they don’t require a special keeping area and wont take up space in the garage either. They can even be kept indoors too in the basement or coat area.

PowerWise: Going by how big your yard or garden is and the kind of terrain on it, (like rocks, hills, ornaments, trees and weeds) you should get a basic idea of whether you need something very high powered or a smaller lighter models for tackling the random weed growth.

WeightWise: Who uses the string trimmer will determine the ideal weight too so you have good balance when actually using it. Gas trimmers weigh in close to 10 to 14 pounds and most of that weight is due to the engine. Heavy trimmers won’t be a sensible option for older people, those with bad backs or those that don’t want the extra maintenance costs.

When it comes to keeping your lawn neat, trimmers are the multipurpose wonder tool. Of course, consider the application, costs and time that you have before you make your choice. Other demands to keep in mind are those hard to reach areas, grass trimmings, thicker brush, edge lines an if the trimmer will meet those demands.
