Based on our tests, this weed eater is best for the casual gardener, or those that use this tool for light lawn maintenance and not in any professional or heavy impact applications.

The Black & Decker LST300 12-Inch 20-volt Cordless Trimmer and Edger is lightweight even with the battery on board, making it easy to use around the yard. Please note that those over 6 feet or taller, might find they have to bend over more a bit more with this weed eater due to the compact nature. The 20-volt battery does provide up to 33% more runtime than previous models but is still not robust enough to hold hours of use, and it will take a few hours to recharge. We found at best, it can provide about 30 minutes of continuous use. We found this to not be a sufficient tool to use if needing this for thick turf and weeds.

Weed Eater Buying Guide

String trimmers, also known as weed whackers, are commonly used at the end of the lawncare process to reach hard-to-reach areas in your yard. String trimmers are overworked and misused because they are used to edge around trees, shrubs, and walkways. Here are some tips to buying a suitable trimmer for your garden:

1. Consider your garden's size

Before buying a trimmer, the owner should consider the garden's size to decide which type of trimmer is suitable for the garden.

An electric corded or battery-powered weed trimmer makes quick work of trimming chores in a small yard. Choose a trimmer with enough runtime to tackle the entire job at once if you have a large yard. Large jobs can be tackled with cordless, battery-powered trimmers, but you may need to purchase an extra battery to ensure you have enough power to tackle the entire yard at once.

2. Type of power source

After knowing the garden's size, you can select the string trimmer that is best for you. With so many options in the trimmer market such as electric, cordless, and gas, here are some tips you should consider.

  • Gasoline fuel system: It is a powerful and versatile device, primarily designed to work in large areas.
  • Corded (Electric) machine: Lightweight, mobile and compact, unlike gasoline one. The electric machine is mainly chosen for small and noise-sensitive areas, environmental-friendly users.
  • The cordless (battery-powered) machine: is even more mobile, flexible, and compact than the electric one.

3. Style of trimmer: Curved or Straight Shaft?

Regardless of whether the appliance is gas, electric, or battery-powered, the shaft serves as the main body.

  • Straight Shaft: In general, trimmers with straight shafts are more powerful than the curved shafts. As a result, they'll be ideal for heavy-duty or dealing with a large yard with dense brush. Their design allows them to reach under overhanging tree branches, low decking, and sharp corners with ease. Moreover, this is also less vibration. Straight shaft trimmers are heavier than curved shaft trimmers, which means they will vibrate less and thus cause less user fatigue over long periods of time. However, when compared with curved shaft trimmers, you'll see that straight shaft trimmers are usually more expensive. Because of their versatility and more powerful performance, they cost more to own.
  • Curved Shaft: The first impression is from its cost, inexpensive than the straight one. If you are looking for a cheap trimmer just for basic trimmer function, the curved shaft trimmer is a better choice. Besides price, the curved shaft is loved by ladies because it's lightweight, easy to use, and maneuver. It's perfect to use for a small garden. You can easily get in and out of tight spaces with these trimmers. Anyway, curved is not recommended for tall people. The short shaft on the curved shaft trimmers, tall people may find them inconvenient to use because they will have to reach down frequently.

FAQs

1. What does a string trimmer do?

String trimmers are used to keep the grass trimmed in places where a lawn mower can't reach. And the edgers are used to clean up the edges of sidewalks and driveways. These days, trimmer and edge can combine to save lots of money when buying separate these two tools. Before buying one, we have some things to consider, such as trimmers shafts.

  • Curved Shaft Trimmers: Curved shaft trimmers are typically lighter in weight, making them ideal for small yards with few shrubs.
  • Straight Shaft Trimmers: Straight shaft trimmers are ideal for larger yards and for reaching under decks, patios, and larger shrubs. Straight shaft trimmers are also more comfortable to use for taller users and can help reduce user fatigue.

2. Which is better 2 strokes or 4 strokes Weed Eater?

4-stroke trimmers are stronger than 2-stroke ones, but both have their own advantages.

A 4-stroke string trimmer is friendly to prevent pollutants, reducing environmental impact, and increasing fuel efficiency. That is the reason why in some states, you may be required to use a cleaner-running 4-stroke trimmer. On a consumer level, the increased fuel efficiency of a 4-stroke model is also appealing. You'll use less gas, saving you money and time when it comes to refueling. Plus, when your parts emit fewer pollutants, they tend to make less noise. This is especially true for 4-stroke trimmers.

While 2-stroke string trimmers are dependable tools because they have fewer moving parts. They are lighter than 4-stroke trimmers and vibrate less, reducing operator fatigue and providing a better trimming experience. Moreover, with the 2-stroke trimmer, the user can is easy to store and maintenance it.

3. Which is better gas or battery weed eater?

Electric weed eaters are better for those who do not want to crank the machine by pulling a string or simple friend-environment. But gas weed eater is more powerful.

Cordless weed trimmers are similar to electric weed eaters, but they run on lithium-ion batteries instead of being plugged in. Instead of pulling a rope, these trimmers are started by pressing a button. And to operate it, the trimmer is quieter than the gas one. Because electric trimmers do not use a combustion engine, they are much quieter to use than gas-powered models.

A gasoline-powered weed eater has a gasoline-powered motor. A two-stroke or four-stroke engine can be found in gas weed eaters. Gas-powered weed eaters have more power than their electrical or cordless counterparts. This means they can tackle woodier and heartier plants and weeds than the others. Go with strong power, gasoline-powered weed eaters can be very expensive to fuel, given the price of both gas and oil.

4. How long does the battery last on a weed eater?

For the newer trimmers, it will run for 20 to 40 minutes when fully charged. To extend the life of your trimmer battery, run it completely down every two months and fully recharge it overnight.

Battery-powered trimmers are available in 18-, 24-, 36-, 40-, 56-, and even 80-volt configurations. You might believe that a higher voltage battery automatically equals more power. In the trimmers market, the manufacture prefers to use lithium-ion batteries.

Lithium-ion batteries have two main advantages: they charge quickly and discharge at a consistent rate, regardless of whether they are fully charged or only partially charged. Non-lithium batteries start out strong, but their power gradually fades. You'd know your battery was almost dead on those old-style batteries because your tool slowly stopped working. All Remington battery-powered tools include a high-capacity, rechargeable 40V lithium-ion battery, ensuring a steady stream of power from start to finish.
