Best Weed Wacker Options

If your lawn features a lot of “interruptions”—trees, shrubbery, pavers, and pathways—odds are that you struggle with a bulky lawnmower to maneuver around and maintain growth around these landscaping highlights. A perfect complement to a lawn mower, the string trimmer tackles overgrown grass in hard-to-mow areas. This lawn tool, also known as a “weed whacker” or “weed eater,” uses a monofilament line (a strong, flexible, hard plastic cord) to do just what its name implies: trim!

Best Weed Wacker – Buyer's Guide

Let’s Cut to the Chase: Shopping Considerations

To make sure that you’re selecting the right tool for your yard, start by getting a grasp on the different variations available.

Pick your power.

The fuel source you need often depends on the size of the yard and how long your string trimmer would need to run to get the job done. That said, you’ll also need to think about what a battery or a tank of fuel adds to the overall weight of the machine.

  • Gas-powered models are powerful and untethered, giving users the freedom to move about the yard without extension cords. As exhaust emissions become a greater concern than ever before, some manufacturers have introduced gas-powered models that create less pollution without sacrificing performance. If you’re interested in buying a more environmentally friendly gas-powered string trimmer, look for the words “low emission” on the packaging. While these tools can handle long weeds better than their electric-powered counterparts, but they’re also more expensive. They’re heavier as well, with many models weighing in at just under 13 pounds.
  • Electric-powered models tend to be even more lightweight and functional, whether a consumer chooses one with a rechargeable battery or a good old-fashioned cord. Corded versions occasionally pose problems maneuvering around a property, since the cord can get tangled or run out of length, but they’re also the most budget-friendly option. Cordless versions, on the other hand, are extremely portable and easy to maneuver, but their battery (or batteries) must be recharged between each use and they don’t perform as well as corded models in tall grasses. That said, recent technological improvements have aided corded and cordless electric string trimmers in catching up with their gas-powered counterparts in terms of performance.

Mind maneuverability.

Whether or not you need a tool with wheels depends largely on the type of terrain you’ll encounter on your property.

  • A wheeled model, sometimes called a “walk-behind,” ideal for handling large patches of rough terrain, thanks to the maneuverability provided by the wheels and typically wider cutting paths. A majority of these machines operate on a gas-powered engine similar to a lawnmower’s and run on two or four wheels.
  • A string trimmer without wheels, though, is far more common and generally effective on even the messiest tangles of grass. Unless you live on a property with extensive weeds and rough terrain, you can likely make do with a model without wheels.

Select a shape.

String trimmers come in two shapes: curved shaft and straight shaft.

  • Curved shaft string trimmers feature a bend at the end of the shaft, near the blades, that makes them shorter in length and—combined with a lighter weight—more comfortable to use. These weed wackers work best for homeowners who need to manage grass and plant growth around (but not underneath) trees and other objects, since their design won’t quite fit into hard-to-reach places.
  • Narrow straight shaft string trimmers boast a greater reach for tall users and those who need to trim far beneath shrubbery or unique landscape features, but they tend to be tougher to use due to their heavy weight and high level of vibration.

Find the right feel.

The most popular string trimmers range in weight from five to 15 pounds. Corded, curved-shaft models are typically the lightest, while gas-powered walk-behinds are the heaviest. Additionally, most weed string trimmers have cutting path diameters somewhere between 12 and 17 inches.
