Benefits of Cordless Weed Eaters

  • Eco-friendly. One of the main benefits of cordless weed eaters is that they are environmentally friendly. This lawn care tool does not require any fuel or a power outlet, as it typically runs on a rechargeable battery.
  • Extended reach. Since cordless weed eaters do not require an electrical outlet, they allow you to reach the most difficult areas of your property without having to use an extension cord.
  • User-friendly. Cordless weed eaters are usually extremely easy to operate compared to gas-powered options. They require less maintenance and are more lightweight than gas-powered weed eaters.

Types of Cordless Weed Eaters

Curved Shaft

Curved shaft weed eaters are the best type of weed eater for open spaces or larger yards. This type of cordless weed eater is not as efficient for use in tight spaces like under fences, bushes, or hedges due to the curved design. Curved shaft weed eaters are generally the easiest to operate of all types of cordless weed eaters.

Straight Shaft

Straight shaft weed eaters are more versatile than curved shaft weed eaters. This type of cordless weed eater can be used in open spaces, but the design is specifically intended for use in tight spaces or hard-to-reach areas of your property. The straight shaft can reach under fences, bushes, or hedges.

Telescopic Shaft

Telescopic shaft weed eaters are the most user-friendly type of cordless weed eater. The shaft is fully adjustable and can be customized to fit your height. This allows you to be completely comfortable while operating your weed eater, and you don't have to worry about any unintended stress or fatigue while working on your lawn.

Key Features

Run Time

The battery run time is one of the critical features of cordless weed eaters. You'll want to make sure to purchase a second battery as a backup option if your battery does not have a long enough run time to work for extended periods on your lawn. Another essential factor that coincides with battery run time is the charge time of your battery and charger. In most cases, you will not be able to operate your weed eater while your battery is charging.

Weight

The weight of your cordless weed eater is another factor to consider. Most cordless weed eaters are relatively lightweight, and that can be important so that you do not become too stressed or tired while working on your lawn. You will also want to make sure that the battery does not add weight to your weed eater once it is charged and installed.

Design

The cordless weed eater's design is a crucial factor depending on the size of your property and the landscape that surrounds it. Straight shaft weed eaters are best for trimming hard-to-reach areas like fence lines or under hedges. Curved shaft weed eaters are best for trimming open spaces or large properties.

Other Considerations

  • Battery. The type of battery included with your cordless weed eater can be an important factor that influences the overall operation of your product. Lithium-ion batteries are the most common because they are the most lightweight and feature a long run time on just a single charge. Nickel Cadmium batteries are less common, but they are much cheaper than lithium-ion batteries. The advantage of this type of battery is that it is affected less by extreme temperatures.
  • Power. The power produced by your cordless weed eater is another essential factor to consider. Make sure to find a product that is the best fit for your specific property and has a sufficient amount of power to trim your lawn properly. Depending on the size of your yard, you may need a different type of weed eater with a larger power output.
  • Warranty. The length and type of warranty are important considerations when contemplating the best cordless weed eater to fit your lawn care needs best. Most reputable manufacturers will include some kind of warranty with their cordless weed eater. Look to purchase a weed eater with a limited warranty that will cover any manufacturing defects or issues with your product for its first few uses.

  • Most cordless weed eaters are not able to charge the battery while in use. If you have a larger yard or will be working for extended periods, make sure to purchase a second battery to use as a backup option.
  • Consider the type of battery before making your purchase. The highest quality batteries will equate to longer durability and longer run time for your weed eater.
  • If you are using your cordless weed eater on a large area or for extended periods, make sure that it is lightweight enough not to cause you any stress, fatigue, or injury. Even though it is lightweight, make sure that it has enough power to trim your lawn.
  • If you are deciding between a couple of different models, always make sure to check the length and type of warranty included with your weed eater. The most reputable companies will typically offer a longer and better warranty.
