What We Like
  • Powerful motor

What We Don't Like

  • Expensive

For a powerful lawn tool that is still easy to start and use, this gas string trimmer from Husqvarna features a SmartStart recoil system and fuel pump that will have you working in just a few minutes. The 17-inch cutting width is one of the widest available at this price and comes with easy-to-use features.

This is a heavy-duty weed eater, which is why the stabilizing handle is so useful. Since it's a gas-powered weed eater, users will need to operate common functions like the choke and purge settings. Husqvarna designed the controls to be intuitive, and the included instructions explain everything very well.

One of the best parts about using a combination tool system is that once you get the hang of using the controls, the learning curve to master the new attachment is quick and easy. 

This weed eater also performs well as a weed wacker, with an impressive 17-inch cutting width, power from a four-cycle engine, and a simple prime and pull start process. It is also quieter than many other gas weed wackers, and it features an adjustable handle for right-handed or left-handed users.

What We Like

What We Like
  • Combination trimmer/edger

  • Budget-friendly

  • Good cutting width

What We Don't Like
  • Needs to plug in

Using a weed eater with a plug-in cord means that you can run it indefinitely without ever having to worry about battery life. It also means that you need to be close enough to an electrical outlet to secure a power source. Generally, plug-in electric weed wackers are not the best option for large areas because of their limited range, but they're great for use in small yards to bypass the need to charge batteries. The Toro 51480 Corded 14-Inch Electric Trimmer/Edger is a reliable combination tool at a great price. The telescoping shaft is made from aluminum, and the wide cutting width is perfect for almost any job.

Weight: 6.3 pounds | Voltage: Not listed | Power Type: Electric | Shaft Type: Straight | Maximum Cutting Width: 14 inches

Final Verdict

Our top pick is the Ryobi 40-Volt Lithium-Ion Brushless Electric Cordless String Trimmer for its great performance, ease of use, and coordinating line of compatible tools from Ryobi. Another great option is the budget-friendly Worx 12 Inch 20 Volt Grass Trimmer/Edger. This lightweight weed eater can tackle just about any weed or overgrown area of your yard while still being easy on your muscles and wallet.

What to Look for in a Weed Eater

Power Source

Like many yard tools, weed eaters come in outlet-powered, battery-powered, and gas-powered varieties. Gas-powered weed eaters are more powerful, but require you to have gas or a mixture of gas and oil on hand and may be more difficult to start up. Electric options are less powerful, but can easily be recharged or plugged in for lighter jobs.

Rotating Head

Some weed eaters can also be rotated to serve as edgers, which cut perpendicular to the ground rather than parallel to it. This feature allows you to clean up areas around your sidewalk or driveway without buying another yard tool.

Adjustable Length

If you anticipate multiple members of your household might be using the weed eater, look for one with an adjustable shaft that can be made longer or shorter, depending on the height of the user.

  • What is the best kind of weed eater for long/thick weeds?

    Gas-powered weed eaters are usually more powerful than electric varieties, making them great for long or thick weeds. If you choose an electric tool, look for an option with a high voltage rating for maximum power against those tough weeds.

    The type of feeder string you use also makes a huge difference in how well the trimmer performs. Your user manual will help guide you, but square, multi-sided, serrated, or round strings will slice through thick weeds easier because of the sharp edges.

    You may need to use a hedge trimmer or brushcutter for bushes and other overgrown areas with thick or tough stems. Investing in a weed eater that has attachments or is compatible with a larger line of yard tools can help you complete a variety of jobs.

  • How long do weed eaters last?

    With routine maintenance, weed eaters can last for years. You will need to replace the string regularly before replacing the weed eater, and may need to purchase a new battery for your battery-operated weed eater. 

  • How do you care for/maintain weed eaters?

    You will need to replace the cutting string periodically, but most models make this easy with a plug-in refillable string spool. If you have a gas-powered weed eater, you will also need to replace the oil to keep the motor operating well and refill it with gas to provide power. Seasonal maintenance, such as a thorough cleaning and proper storage, is important to keep your weed eater working properly. If you tackle a particularly dirty job, make sure to clean off any brush and debris before putting your weed eater away.
