Best String Trimmers 2020 – Reviews by Experts

A string trimmer is known by a variety of names across the world, the most popular ones being ‘line trimmer’, ‘weed eater’ and ‘strimmer’. It is a power tool used in gardens and farms for weeding or cutting grass or unnecessary smaller plants that have overgrown around objects. You can remove plants on an irregular terrain as well. A string trimmer doesn’t employ a blade to cut plants and grass. It works using a monofilament line which is quite flexible as well.

The tool in itself has a long handle attached with a cutting tip which has the monofilament line. This is sharp enough to cut most types of grass. The flexibility of the monofilament line makes it easy for you to navigate around irregular areas and cut wherever you want. The string trimmer works using a rotating cutting head containing the monofilament line.

Some of them can be adjusted; you can change up the angle of the rotating head to fit the area that you are trimming. You also have the option of fuel string trimmers which use an IC Engine in the machine which uses either gasoline or diesel as the fuel, or you can buy an electrical one which works with obviously, an electric motor.

Types of String Trimmers:

There are 4 types of string trimmers available in the market. The details on all these are given below:

1. Electric String Trimmers

  • These are simpler and easier to start.
  • They run on electric motors which are easier to start and switch off as well.
  • These have a noticeably small sound level, they create much less noise than the gas one, which should be kept in mind.
  • They are available in the cordless and corded variants.
  • The cordless ones are understandably easier to move around because there is no wire attached to it. They operate on 20 to 40 or 80 volt batteries, based on the power of the motor that you are using. As stated earlier, the power rating of the string trimmer that you choose should depend on how large your farm is and how long you are going to be using your string trimmer. These batteries can last from 30 minutes to a number of hours.
  • The corded string trimmers that you can get in the market are much lighter than the cordless ones you get. This is because of the lack of battery in the corded ones. You also do not have to charge it and it does not stop during work as it has a continuous power supply. It would be more difficult to work with this as corded string trimmers have a little flexibility with the amount of area they can cover. You need extension cords to expand the area that they can cover, which becomes a hassle at times.

2. Gas String Trimmers

  • Gas String trimmers are used to cover more areas and to cut more growth than just small weeds and grass. They are more powerful than electrical trimmers.
  • They are a little tougher to start up, as they use a pull-start to be able to crank the motor. You can also purchase a separate attachment which basically starts the machine for you at the push of a button and you do not have to use this cord.
  • They run for a longer time than electrical string trimmers as well, as they do not need to be charged and they run on petrol or diesel.
  • You do need to keep the motor properly fueled and maintained by lubrication and proper maintenance methods.

3. Walk-behind String Trimmer

  • These have wheels and a bar that you can use to drive it around like a cart, which is easier to maneuver than hand-held string trimmers.
  • They also have wider area coverage as the line that cuts is bigger than that of hand-held trimmers.
  • These are mostly gas powered and are easier to start because of its structure although it does have the pull start mechanism with the recoil spring.
  • It is used for tougher bushes and harder terrain, which is why the cutting line becomes worn out easily. You have to replace the lines regularly.

This Best String Trimmers Review is about the best string trimmers on the market, which have the best specifications and efficiency along with the best value for money.

Factors to Consider Buying of Best String Trimmers:

While buying a string trimmer, there are many things that you do need to keep in mind. There are many things which make one better from the other, and we are here to help you find the right one based on your needs. Look through the following points to see what you really require:

  1. There are 3 types of string trimmers which you should know about: Electric string trimmers, gas powered string trimmers and walk-behind string trimmers. The next segment contains details about each of these.
  2. The size of your yard is also very important in your selection of a string trimmer.
  3. If you have a yard larger than 1 acre, you should get a cordless gas trimmer for cutting to be done in sufficient time and for the trimmer to work for a longer time.
  4. For lawns having a size ranging between half an acre to an acre can go with cordless electric string trimmers with 40 to 80 volt wattage, but having a gas trimmer isn’t bad either.
  5. For smaller yards having a size less than half an acre, using a corded string trimmer could be a good idea as well if you have an electrical port nearby. You can also use a 20V to 40V cordless trimmer for the easiest and fastest trim job.
  6. In case your terrain is really tough, so much that the string trimmers do not really work anymore, you can look into Brush Cutters, which are like the walk-behind string trimmers. They use rotating saw blades instead of the line cutter. This helps cut woodier shrubs and weeds in the area that you need to trim.
