​A newly manicured yard or lawn will increase the curb appeal of your home almost instantly. However, keeping your lawn in tiptop condition requires plenty of time, effort, and, most importantly, an investment in the right tools. A weed wacker is one such tool, which occasionally gets overlooked in favor of a lawnmower. When it comes to lawn maintenance, however, you need not neglect any tool—especially weed eaters. These tools, also known as an electric weed wacker, a string trimmer, and a weed trimmer, serve double duty, sometimes as a mini-mower, and other times as an edger or hedge trimmer.

Finding the right string trimmer isn’t difficult. You just have to be specific about what you’re looking for. Consider the size of the lawn as well as how fast and efficiently you want the trimmer to slice through grass and weeds.

Weed Wacker Buying Guide

Every gardener or homeowner would want tools that make his life easy. Few tools offer the kind of performance and convenience that a weed whacker does. Weed eaters have become a staple when it comes to taking care of yards and lawns. Currently, there are hundreds of different models on the market. So, how do you determine the best weed wacker for your needs? Here are a few aspects to help you narrow down that list of options.

Engine Type

The most important feature that you should be looking at when it comes to weed eaters is the type of engine. This is going to determine a lot of your decisions. The two main types of engines you will get are electric and gas-powered. With electric, the string trimmer is powered by a rechargeable battery or traditional cord that has to be plugged into an electric outlet. Conversely, gas-powered weed wackers tend to have more power, but they’re also bigger and suitable for heavy-duty projects. And since they run on fuel, maintaining gas string trimmers can be expensive.

The electric models do not have as much power as the gas-powered models. However, these electric weed eaters are fitted with different kinds of motors, which have varying torque and total output.

Perhaps the best option for those who want minimal maintenance is a battery-powered weed eater. It may need to be charged several times but it gives you the utmost mobility. The corded models are a bit limiting since one can only go as far as the cord allows you to.

Feed System

There are two major types of feed systems. A feed system is a mechanism that determines just how much string gets fed out through the head. Originally, this mechanism was referred to as a bump feed since an individual was forced to press downward in a bumping motion so as to release more of the line.

Overall, this system gives users more control when it comes to the length of the line being used. Unfortunately, it also increases the risk of damaging the weed eater since one has to apply a great deal of force in smashing it to the ground.

The second variation of the feed system is known as an automatic feed. As you might have guessed, this mechanism works automatically in that the weed eater extends the feed line as you go. The greatest benefit of an automatic feed is that it does not require the use of any force. On the flipside, these mechanisms do not give users as much control and fixing them when they break is difficult.

Cutting Width

Every weed wacker has a specific cutting width that is expressed in inches. The average width is between 12 and 14 inches. The cutting width is simply the space in which the weed eater cuts down grass without forcing the user to move an inch. That said, a bigger cutting width means that an individual can cover a large area using minimal effort, which makes them suitable for large yards. On the other hand, weed whackers that have a small cutting width are better suited for small yards.

This does not necessarily mean that a string trimmer with a bigger cutting width is better. Ultimately, your choice for a weed eater boils down to how efficient it is, how comfortable you are using it, your physical strength and the needs of your yard. Depending on the situation at hand, selecting a trimmer that is too big or too small could cause more problems for you.

The Bottom Line

Weed whackers, also known as string trimmers, serve two main roles: to access those hard-to-reach areas of a garden that a lawnmower cannot—and to keep your edges looking tidy.

There are three main variations of weed eaters: some are powered by batteries, by gas, or batteries. Regardless of the model, you decide to go for, ensure it provides sufficient power and a large cutting width to help you cover a large area within a short amount of time.
